A: Light bacterial fertilizer is a new type of clean fertilizer. It is based on the scientific principle of "increasing the concentration of carbon dioxide around cash crops can increase crop yield", and selects several substances-microalgae, which can provide crops with high-efficiency nutrition and high-efficiency carbon dioxide adsorption. After scientific formulation and physical methods, the successful appearance of light bacterial fertilizer will end the 40-year history of "chemical agriculture" in China and open a new chapter of "ecological agriculture". It is the leading product for the Chinese nation to achieve the grand strategic goal of "green development, circular development, low-carbon development and building a beautiful China"; It can achieve the purpose of "eliminating the residue of harmful substances in the environment and ensuring local production and income increase".
2. What raw materials are used to synthesize photosynthetic bacterial fertilizer?
Answer: Light and bacterial fertilizer are ecological organic water-soluble fertilizers. The core components include: microalgae (nanocarbon factor), metalloproteinases (efficient catalyst, promoting absorption), Bacillus subtilis (promoting rooting and preventing soil-borne diseases), etc.
3. What is the function of microalgae (nano-carbon factor) contained in light and bacterial fertilizer?
A: It is known that leguminous crops, some bacteria and slight light can directly fix nitrogen in the atmosphere. In addition, microalgae also have special solidification and environmental protection functions. Photobacterium fertilizer combined with microalgae has the following functions: ① It is fully beneficial for microalgae to contain up to 70% protein and rich trace elements as nutrients for crops to absorb and transform; More importantly, it can give full play to the solidification and environmental protection function of microalgae.
The solidification and environmental protection functions of microalgae include:
1. can fix nitrogen in the atmosphere, provide nitrogen fertilizer for crops through foliage, and reduce nitrogen particles in the air (nitrogen particles and nitrogen oxides are a large number of components of PM25), which can effectively reduce and alleviate air smog.
2. Microalgae can fix and remove harmful heavy metal residues (arsenic, lead, cadmium, etc.) when acting on crops. ), chemical fertilizers and pesticide residues, and refractory organic matter in the soil, so as not to pollute crop products, thus ensuring the organic quality of agricultural products.
4. What is the action mechanism of light and bacterial fertilizer?
A: Spraying light and bacterial manure on the surface of crop leaves and stems can adsorb and enrich carbon dioxide in the air around plant leaves and stems for crops to absorb, thus strengthening photosynthesis, increasing photosynthetic rate, inhibiting photorespiration, accelerating the production of chlorophyll, and improving and strengthening the functions of crop growth and dry matter accumulation.
5. What is photosynthesis?
Answer: Photosynthesis is a process in which green plants use the energy of sunlight to synthesize organic matter-carbohydrates from carbon dioxide and water and release oxygen, which is called photosynthesis.
Knowledge related to photosynthesis:
1. Photosynthesis must be carried out in chloroplasts of green plants, because only chlorophyll, the pigment of chloroplasts, can absorb light energy and convert it into chemical energy;
2. Photosynthesis needs light, which is the energy source of photosynthesis and the condition of chlorophyll formation;
3. The three elements needed for photosynthesis are carbon, hydrogen and oxygen, namely carbon dioxide (CO2), hydrogen (H) and water (H2O), which are raw materials for synthesizing carbon compounds (CH2+O2). Our agricultural production is the process of crop photosynthesis to produce organic matter, and it is wrong to apply nitrogen, phosphorus and potassium for 40 years.
6. What is light breathing?
A: Plants absorb carbon dioxide during the day, carry out photosynthesis and exhale oxygen, which is called photosynthesis; The process of absorbing oxygen and exhaling carbon dioxide at night is called photorespiration. Photosynthesis is to create and increase nutrition for crops, while photorespiration is to consume nutrition. Therefore, inhibiting photorespiration and minimizing the energy loss of photorespiration have become important measures to improve agricultural output. Suppressing night photorespiration and minimizing the energy loss of photorespiration is a unique scientific and technological innovation of photobacterial fertilizer, which is of great significance to high yield of crops.
7. What is the core technology of applying light bacterial fertilizer to obtain higher yield than applying chemical fertilizer?
Carbon dioxide capture technology. Carbon dioxide is an inorganic substance, which cannot be completely burned during oxidation. After the "energy upgrade" of photosynthesis, carbon dioxide is converted into carbohydrates (from inorganic substances to organic substances). With the help of green plants, light and bacterial manure can synthesize glucose, starch, fat and protein rich in energy and nutrition through photosynthesis, and restore the natural biological chain and human health food chain, which is a great contribution to the earth and mankind.
Eight, what is the principle of light and bacterial fertilizer to increase production?
Answer: The three elements of plant growth are sunlight, air and water, and the carbon and hydrogen in the air are the "food" for plant growth. As long as the concentration of carbon dioxide around crops increases, it means that crops are "full, grow fast and have high yield". At present, the concentration of sulfur dioxide in the air is 350PPM, and the required concentration for high yield of crops is 550- 1000PPM. How can 350PPM make "not enough to eat" crops yield high? Photobacterium fertilizer can enrich carbon dioxide in the air on the stems and leaves of green-leaf crops, so that its concentration can reach more than 550PPM, and it can be absorbed and utilized by crops under the action of sunlight, thus achieving the goal of high yield without chemical fertilizer.
Nine, why do you say that after applying light bacterial fertilizer, you can not apply chemical fertilizer?
A: There are 16 elements in plants, of which carbon, hydrogen and oxygen account for more than 96‰, while the sum of nitrogen, phosphorus, potassium, medium and trace elements only accounts for 4%. For 40 years, people have only been superstitious about the supplement of mineral elements such as nitrogen, phosphorus and potassium, while ignoring the satisfaction of autotrophic elements such as carbon, hydrogen and oxygen in crops. Because carbon dioxide is the "food" of plants, its growth and dry matter accumulation depend on carbon, hydrogen and oxygen, and the nutrients that maintain human life are all composed of carbon, hydrogen and oxygen. Moreover, research and practice have proved that plants can completely obtain carbon, hydrogen and oxygen from air and water, and there are ways to increase the concentration of carbon dioxide around crops, so as to obtain high yield. As for nitrogen, potassium and trace elements, they all exist in crop straw, animal manure and soil, and do not need to be supplemented by chemical fertilizers.
X. why is it said that the application of light bacterial fertilizer is good for soil?
A: Spraying photobacterium fertilizer on the leaves and stopping applying chemical fertilizer can naturally restore the soil environment, improve soil acidification, hardening and rocky desertification, and enhance the ability of water and gas retention and microbial reproduction. Of course, there are many benefits.
XI。 Why can photosynthetic bacteria fertilizer resist diseases?
A: The action principle of photosynthetic bacteria fertilizer accords with the real science. He uses leaves to promote roots, which is not harmed by soil worms. After spraying, the roots of crops do not rot, and the disease resistance is enhanced. Photosynthetic bacterial fertilizer can effectively prevent diseases and diseases.
Why can light and bacterial fertilizer resist insects?
A: After crops are sprayed with photobacterial fertilizer, the concentration of carbon dioxide among crop groups increases, and the living environment of pests becomes anoxic, which is not conducive to the reproduction and growth of pests, leading to the death of pests and indirectly playing a role in preventing pests.
Thirteen, why is it said that eating crop food sprayed with light and bacterial fertilizer is good for human health?
A: After using photobacterial fertilizer, you can use less pesticides instead of chemical fertilizers. Chemical fertilizers, chemical pesticides and heavy metal residues no longer pollute agricultural products, food is green and organic, and human health is guaranteed.
14. Are there any restrictions on the application of photobacterial fertilizer?
Answer: the application of light bacterial fertilizer is not limited by any conditions, as long as there is sunshine, air, water and temperature, the cost is low. The input is lower than that of chemical fertilizer, the output is higher than that of chemical fertilizer, and the quality is better than that of chemical fertilizer. People like it and accept it easily.
Fifteen, how to give full play to the maximum benefit of photobacterial fertilizer and matters needing attention?
A:
(1), there are five factors that determine crop yield:
& lt 1 & gt； Leaf area,
& lt2> photosynthetic intensity,
& lt3> photosynthetic time,
& lt4> Breathe
& lt5> Economic coefficient (economic output-biological output)
? (2) Ways to improve the utilization rate and yield of crop light energy:
& lt 1 & gt； Reasonable close planting;
& lt2> Intercropping and Multiple Cropping;
& lt3> Select a compact lodging-resistant dwarf variety with upright upper leaves and inclined middle and lower leaves;
& lt4> Strengthen site management.
? (3) Prevent soil hardening, ensure the roots of crops are ventilated, and drain water in time after rain. Anaerobic respiration is not conducive to crop growth.
? (4) Attention should be paid to illumination and application of bacterial manure: with the change of temperature, the optimum temperature of photosynthesis is 25 ~ 30℃, which starts to decrease at 35℃, stops at 40~50℃ and stops at the lowest temperature of 0~2℃. Therefore, when the temperature is lower than 10℃ and higher than 35℃, do not spray light and bacterial fertilizers.
? 5. Water is an important raw material for photosynthesis. When the weather is dry, photosynthesis is inhibited to 10~90%, and soil and atmospheric moisture affect the water content of leaves. When water is scarce, the stomata are closed, which affects the entry of carbon dioxide into the leaves.
? [6]. At the same time of spraying bacterial fertilizer on the leaves, we should also apply sufficient organic fertilizer (farmyard manure) at the roots of crops, which not only meets the needs of crops for nitrogen, phosphorus and potassium, but also meets the activities of soil microorganisms and decomposes carbon dioxide released by organic matter. Part of soil carbon dioxide is dissolved in soil solution and absorbed by roots, and part of it is diffused into the air and absorbed by leaves. Organic matters such as crop residues and animal manure must be applied to the field after harmless treatment, return to nature, restore the biological chain, and achieve natural ecological balance. At the same time, organic fertilizers such as nitrogen, phosphorus and potassium should be applied to crops. Therefore, the combination of photobacteria fertilizer and organic fertilizer is the most scientific application method.
? Once, when growing vegetables in greenhouse or using plastic film to raise seedlings, after spraying light and bacterial fertilizer, we should pay attention to solving the contradiction between high temperature and insufficient light, uncover the film in time, ventilate and cool down, reduce respiratory consumption and cultivate strong seedlings.
⑻ To cultivate vegetables in greenhouse, the temperature should be adjusted to 25℃ during the day, which is to improve photosynthetic efficiency (spraying photosynthetic bacteria fertilizer is the most effective at present), and the temperature should be lowered at night to reduce the consumption of photorespiration energy, so as to accumulate more energy and nutrients.
? (9) In the vegetable greenhouse, in order to prevent the soil temperature from changing sharply, it is suggested that tap water should be put into a large tank and irrigated after the water temperature is slightly warmer, which is more conducive to the growth and development of crops.
? ⑽. Why not irrigate at the hottest time at noon?
Answer: It is because irrigation suddenly lowers the soil temperature, which affects the root system and water absorption, and even causes crops to lose water balance, wither and die. It is forbidden to use light and bacterial fertilizers in rainy days, foggy days and windy days. Unfavorable weather affects photosynthesis, which will greatly reduce the benefits of light and bacterial fertilizer.
Sixteen, what is pollution-free food?
A: There are two pollution-free quality indicators: the content of heavy metals in products and the residue of chemical fertilizers and pesticides (veterinary drugs) meet the requirements of national pollution-free food standards.
17. What is green food?
A: The main features are:
1 safe. Pesticide residues, veterinary drug residues, heavy metal pollution, biological pollution (such as fungi, bacteria, viruses and parasites) and environmental pollution shall not exceed the standard;
2 nutrition. Green food emphasizes the double guarantee of "safety+nutrition";
3. Environmental protection. Pay attention to "environment+economy" in green food.
Eighteen, what is organic food?
A: In the production and processing of food raw materials, it is forbidden to use chemicals such as pesticides, fertilizers, growth hormones, chemical pigments and preservatives, and it is forbidden to use genetic engineering technology, which is more demanding than green food.
Nineteen, what is a toxic substance?
A: Toxic substances include mercury, arsenic, phenol, fluorine, lead and cadmium. And most of them coexist with phosphate rock (phosphate fertilizer used in agriculture), sulfur dioxide, radioisotopes, fertilizers and pesticide residues. These toxic substances are continuously discharged into the environment, immediately participate in the cycle of the ecosystem, can not be discharged in crop metabolism, accumulate in organisms for a long time, and gradually enrich with the transfer of nutrients, thus increasing the harm to organisms and even leading to their death. We should be highly alert to toxic and harmful substances entering the ecosystem, which not only poisons the ecological environment, but also poisons human beings themselves.
