Returning straw to the field

1. The field is covered with straw. After wheat sowing is completed, 250-300 kg rice straw per mu is cut into 10-20 cm straw sections, and the fields are evenly covered so that the grass does not pile up and the land is not exposed.

2. The rape field was covered with straw. When transplanting rape, the seedlings should be planted in the hole where sufficient base fertilizer is applied, and then the whole field should be evenly covered with 300 kg of rice straw / mu. The grass should not cover the hole (seedling) and the soil should not be exposed, and at the same time, the comprehensive control and necessary field management measures should be taken.

3. Drainage and irrigation. If you encounter more Rain Water during the period of wheat sowing and rape transplanting, you should keep the gully communication inside and outside the field, and there is no stagnant water in the ditch after rain. After straw mulching, water should be irrigated once in case of drought, or clear dung water should be applied once, with one ton per mu.

4. Formula fertilization. According to the target of soil fertility and crop yield, balanced fertilization was carried out with organic fertilizer and inorganic fertilizer, nitrogen, phosphorus and potassium. In order to adjust the ratio of carbon to nitrogen, promote the activity of microorganisms and accelerate the maturity of straw, it is necessary to apply 5-10 kg urea per mu.

5. Chemical weeding. Herbicides should be applied 3-7 days before sowing wheat or rape transplanting.
