Diligent planning and autumnal delay After the planting of vegetables, attention should be paid to diligent work, so that the permeability of the soil can be enhanced, which is conducive to the growth of vegetable roots. After the general autumn delay of vegetable planting, should be scratched again every 3 to 5 days, and every time after watering, must be timely scratching. Care should be taken to avoid overdipging the soil. If the soil is too deep, it is easy to agglomerate, but it should not be too shallow. The shallow effect is not good. Generally, the depth of the ploughing should be 3 to 5 cm. Watering volume should not be too large Watering should pay attention to controlling the amount of water, not too large, in particular, can not let the water diffuse over the ridge. If the water passes over the ridge, the ridge will be poured, resulting in reduced soil permeability, resulting in root breathing difficulties, unfavorable growth of the roots of the vegetables, and even causing root failure. Therefore, late autumn vegetables should be watered with a small amount of water, and the amount of watering should not be too large. Covering the film can not be close to the ground. When covering the film on the autumn delayed vegetable colonization line, it is best to use a bamboo or iron wire to support the plastic film. After watering under the film, the plastic film will not cling to the ground and make the soil breathable. reduce. Covering crop stalks between lines of operation Because vegetable farmers trample on agricultural operations for a long time, the soil tends to be tightly packed and has poor air permeability, which is unfavorable to the extension of vegetable roots. The best way is to cover a layer of crop stalks between the operating lines, so as to avoid the soil being solid, but also to keep warm and dehumidify. Adding bio-fertilizers Bio-fertilizer is a good fertilizer to improve soil and roots. After application, it will use microbial activity to achieve bulky soil, improve soil structure, and enhance soil permeability.
