Healthy eating method of corn
Eat coarse grain corn products, such as Wowotou, millet porridge, corn porridge, black rice porridge, corn flour, corn paste, sorghum rice porridge, corn carrot steamed buns, glutinous rice bean buns, rye pot stickers, rye scrolls, rye steamed buns, etc. , are good coarse-grained corn. Few young people like to eat these coarse grains, and they don't want to eat them if they feel bad. In fact, these coarse grains are the healthiest and most effective food. They can prevent and improve obesity.
Drinking boiled corn water directly as boiled water can play a good role in losing weight. Principle: The water for boiling corn has diuretic effect, especially for people with edema and obesity, which can effectively eliminate edema and prevent obesity.
Nutritional value of yellow corn residue
1. Yellow corn residue has a high cellulose content, which has the characteristics of promoting gastrointestinal peristalsis and accelerating fecal excretion, and can prevent and treat constipation, enteritis and intestinal cancer.
2. Vitamin E contained in yellow corn residue has the functions of promoting cell division, delaying aging, lowering serum cholesterol, preventing facial lesions, relieving arteriosclerosis and brain function decline.
The researchers pointed out that yellow corn residue contains lutein and zeaxanthin, which can resist eye aging. In addition, eating more yellow corn can also inhibit the side effects of anticancer drugs on human body, * * * brain cells and enhance people's brain power and memory.
4. In areas where corn is the staple food, the incidence of cancer is generally low, which may be because corn is rich in magnesium and selenium, which inhibits the growth of tumors. In particular, corn also contains more glutamic acid, which has the function of strengthening the brain. Glutamate can help and promote the respiration of brain cells. In the process of physiological activities, it can remove waste in the body and help eliminate ammonia in brain tissue, so it can strengthen the brain if eaten regularly.
Benefits of eating yellow corn residue
1, corn residue can prevent intestinal cancer and constipation.
Corn residue has a good preventive effect on human intestinal cancer and constipation, because corn residue contains a lot of cellulose, which can promote the peristalsis of human intestine and make human feces excrete quickly. Some toxic substances in the intestine will also be excreted with feces, so eating corn residue at ordinary times can prevent human constipation and prevent the occurrence of intestinal cancer.
2. Corn residue can delay aging.
Corn residue can delay human aging. It contains a lot of vitamin E, which can promote cell division and regeneration and delay aging after being absorbed by human body. In addition, it can also remove cholesterol from human body and delay the aging of panel. In addition, eating more corn residue at ordinary times is also good for preventing hyperlipidemia.
3. Corn residue can protect eyes.
Corn residue can protect eyes. Contains lutein and zeaxanthin, which can delay eye aging, prevent vision loss and effectively improve human visual function. In addition, these two substances can also inhibit the growth of cancer cells and reduce the side effects of cancer drugs on the human body. It is an ideal food for preventing cancer.
Management method of planting corn
First, thinning and fixing seedlings
Increasing planting density is an important measure to achieve high yield of maize. According to the characteristics of varieties and the level of soil fertility, the suitable density should be determined, and the planting density should be ensured by spacing and fixing seedlings in time. Generally, seedlings should be checked immediately after emergence, and two plants should be left near the same row or adjacent rows for early replanting. Seedlings should be established at intervals of 3 leaves, with 5-6 visible leaves and 4-5 spreading leaves. We should eliminate weak seedlings, diseased seedlings and insect seedlings, keep strong seedlings, keep neat seedlings and tidy seedlings to improve the uniformity of the population. For density-tolerant varieties and high-yield fields, the suitable seedling density is about 4500 plants per mu, and for sparse varieties and plots with poor soil fertility, the suitable seedling density is about 3500 plants per mu.
Second, scientific fertilization.
Balanced fertilization should be carried out according to the corn yield target and soil fertility level in various places. On the basis of applying sufficient base fertilizer to winter wheat in the previous crop, mainly apply chemical fertilizer * * * urea * * *, and pay attention to increasing the application of phosphorus, potassium and trace fertilizers, and apply phosphorus and potassium fertilizers at one time. Nitrogen fertilizer operation adheres to the principle of light seedling fertilizer, heavy trumpet fertilizer and supplementary flower fertilizer. At jointing stage, * * 15-20 cm * * nitrogen fertilizer was deeply applied along one side of the seedlings, accounting for about 30% of the total nitrogen fertilizer, which played a role in promoting roots and strengthening seedlings. Topdressing about 50% of total nitrogen at the stage of big bell mouth to promote large panicle and more grains, pay attention to deep application and combine weeding and topdressing with intertillage. Topdressing 20% total nitrogen at grain filling stage can improve the photosynthetic capacity of leaves and increase grain weight.
Third, rational irrigation.
According to the law of corn water demand and soil moisture, master the best irrigation period and supply water in time. After jointing, the roots, stems and leaves of maize grow rapidly and enter the stage of male and female ear differentiation, and the field soil water capacity should be kept at 65-75%. The flowering period is the peak period of water demand for maize, and the water content of 1 m soil layer is required to be no less than 70% of the field water capacity. The filling stage is the key period of yield formation, so it is necessary to ensure the demand of corn for water, effectively increase the number of grains per ear, prevent bare stalks and increase the 1000-grain weight of corn. In addition to the seedling stage, irrigation should be done in time when the field water capacity is lower than 60% in each growth period.
Fourth, weed control.
For plots with good soil moisture, 200-250 ml of 40% E-A mixed solution can be directly sprayed per mu, or 33% pendimethalin * * Tian Bu * * EC 100ml and 72% tole EC 75ml with 50l of water can be mixed and sprayed in a closed way. For plots with poor soil moisture content, spray 4% Yunongle SC * * * nicosulfuron * * 100 ml and 50 liters of water per mu at the stage of 3-5 leaves of corn seedlings and 2-5 leaves of weeds, or mix 20% paraquat * * Wu Ke * * aqueous solution with 50 liters of water at the stage of 7-8 leaves of corn.
Five, chemical prevention and fall prevention
Lodging, especially in the middle and late stage, is an important factor affecting corn yield. On the basis of selecting density-tolerant and lodging-resistant varieties, it is necessary to cultivate the soil in time and control it in time to prevent lodging. For plots with high density and serious lodging risk, 200 times of 50% chlormequat chloride solution can be sprayed before booting stage to enhance the lodging resistance of plants and improve the ventilation and light transmission conditions of groups.
