(1) source extension
Expand the area of green vegetation and increase the capture of solar energy.
(2) A powerful library
Strengthening the reservoir refers to strengthening the storage energy and conversion efficiency of the reservoir to ensure a large amount of bioenergy output.
(3) River closure
Through various channels, the energy will be trapped in the agricultural ecosystem as much as possible, so as to expand the cycle, improve the utilization efficiency of agricultural resources and reduce the excessive dependence on fossil auxiliary energy.
(4) Reduce consumption
Reduce consumption, save energy, reduce unnecessary energy losses, and develop modern agriculture that saves energy, water, land and energy.

Construction and optimization of efficient agricultural ecosystem (practical skills);
1, understanding soil and crops
The construction of agro-ecosystem needs to understand soil and crops first. Through soil testing and understanding crops, we can understand the nutrient situation of soil and the growth demand of crops. Replenish nutrients to the soil to make it more suitable for crop growth and improve crop yield and quality. At the same time, we should also pay attention to the growth cycle and habits of crops in order to arrange the planting time and mode reasonably.
2. Protect the soil ecosystem
Protecting soil ecosystem is an important link in building efficient agricultural ecosystem. We can reduce soil erosion and nutrient loss and protect the stability of soil ecosystem through reasonable farming methods, such as crop rotation, intercropping and plastic film mulching. At the same time, it can also increase soil organic matter content and improve soil fertility through biodiversity protection and straw returning.
3. Scientific fertilization and pest control
Scientific fertilization and pest control are the keys to ensure the healthy growth, high yield and high quality of crops. Rational fertilization can improve crop nutrient utilization efficiency and yield, while reducing soil pollution and environmental pollution. Pest control can prevent the damage of pests and diseases to crops and reduce crop yield reduction and death. When choosing fertilization and pest control methods, we should comprehensively consider factors such as crop types, soil types and environmental conditions, and adopt scientific and safe methods for fertilization and pest control.
