The returning of corn stalks can not only increase soil organic matter content, improve the structure of soil aggregates, and increase soil water and fertilizer retention performance. However, the following points should also be taken into account during the specific implementation:
1. When the corn is fully mature, pick the ear in time and remove it together with the loquat leaves. After avoiding pruning corn stalks, the panicles should be picked so as to avoid the yellowing and drying of the straws in the field. The crushing effect is poor and it is not easy to rot.
2. After crushing and picking, crushing operations should be carried out in time. When operating, adjust the tractor's working speed and stubble height. Beware of missing cuts and blades.
3. Application of nitrogen fertilizer to soil microorganisms When decomposing crop straws, certain nitrogen is needed, which is prone to compete with crop seedlings for available nitrogen in the soil. Therefore, the amount of 10 kg of ammonium bicarbonate per 100 kg of straw must be supplemented to accelerate the decomposition of straw. Supplemental nitrogen fertilizer is still stored in soil after being used by microorganisms, and its utilization rate is higher than that applied to uncultivated cultivated land, and nitrogen deficiency and yellowing at seedling stage can be avoided.
4. After rotary tilling or smashing, it is necessary to use a heavy-duty disc to cut it twice to further shred the straw and root pods. After the hoe is smashed, it should be deep-turned and capped in time to play a role in smashing the soil and make the stalks. The fertilizer is mixed with the soil and distributed in a 0 to 10 cm soil layer. Do not be heavy, leaking, and tightly covered, so as to avoid loss of cultivation, ploughing after farming, in order to facilitate sowing.
5. After the straw is returned to field, the water content of the soil will be reduced due to water absorption and microbial decomposition of the straw itself. Therefore, timely watering is required to accelerate soil settling, promote close contact between the straw and the soil, and prevent overhead.
6. The quantity of returning field should be suitable for returning crops to straw, but it is not as good as returning farmland. The number of returning fields should be determined according to the water source and farming conditions. In principle, it should be ensured that the returning field straw is fully rotted and the quality of the tillage is not affected. Advocate returning 300-400 kilograms per acre is appropriate, too much damage to crop root growth.
7. Prevention of Diseases and Insect Pests When straw is returned to the field, it is necessary to use well-grown stalks instead of returning fields with pests and diseases to control the number of insect pests in the coming year and the primary source of infection.
8. Seeding Because of the straw returning, the crop fiber in the soil is increased. In order to ensure the operation quality, it is better to use mechanical sowing to ensure the consistency of the depth and reduce the air leakage situation of wheat aerial and wheat roots.
