Picking: When the maize is fully ripe, pick the panicles in time and take them off together with the loquat leaves. After avoiding cutting down the straw and picking the panicle, the straw will not turn yellow and dry in the field, resulting in poor crushing effect and not easy to rot.
Crushing: After the picking of the ear, the crushing operation is performed in time, and the tractor's working speed and stubble height are adjusted during the operation, and it is necessary to prevent leakage and blade hitting.
The application of nitrogen fertilizer: When the soil microorganisms decompose the crop straw, it needs a certain amount of nitrogen, and it is easy to compete with the crop seedlings for the available nitrogen in the soil. Therefore, it is necessary to add nitrogen fertilizer at a rate of 10 kg of ammonium bicarbonate per 100 kg of straw to accelerate straw rot.
Rotary tillage or tiller: After the straw is crushed, be sure to use a heavy-duty disc harrow twice to further chop the straw and root pods. After the rake is hauled in, it should be deep-turned and covered in a timely manner to protect the smashed soil and make the straw and fertilizer. The soil is mixed and distributed in 3-10 cm of soil. It is necessary to make sure that it is not leaked or covered so that it will not be lost or lost. After ploughing, it should be flattened to facilitate sowing.
Returning soil to the field: After the straw is returned to the field, the water content of the soil will be reduced due to water absorption by the straw itself and decomposition by the microorganisms. Therefore, timely watering is required to accelerate the sinking of the soil and promote close contact between the straw and the soil to prevent overhead.
The quantity of returning field should be suitable: The amount of returning straw should be determined according to the water source and cultivation conditions. In principle, it should ensure that the returning field straw is fully rotted and does not affect the ploughing tillage. It is appropriate to use 300-400 kg of straw per acre.
Prevention of pest and disease transmission: When straw is returned to the field, it is necessary to use well-grown stalks, and do not return fields with pests and diseases to control the number of pests in the coming year and the initial source of the disease.
