One is to turn the soil deeply. Before planting the vegetables, it is necessary to turn the soil deeply, it is best to turn the shovel 30 cm deep, and then use a rotary tiller to thin it. In this way, the soil is not only breathable and permeable to water, but also conducive to deep rooting.
The second is to increase the application of organic fertilizer. Insufficient organic matter in the soil and excessive use of chemical fertilizers often cause soil compaction and poor permeability. Therefore, increasing the application of organic fertilizer is an important measure to improve soil permeability and change soil properties. According to the planted crops, 15 to 25 cubic meters of chicken manure can be applied per mu.
The third is to change the cultivation method. Changing the cultivation method can also improve the air permeability of the soil. For example, the ridge cultivation is carried out in the ditch, so the ridge surface has good permeability and the temperature increase is obvious. The root soil of furrowed vegetables is often watered, and the permeability is poor, which is easy to cause roots. Therefore, in vegetable cultivation, ridge cultivation is advocated.
Fourth, pay attention to the use of biological bacterial fertilizer. After applied to the soil, the biological bacteria in the biological fertilizer will multiply in a large amount in the soil, play a role in activating and loosening the soil, and have a significant promotion effect on improving the soil structure and increasing the soil permeability. It can apply 150-200 kg of bio-fertilizer per acre or 25-30 kg per acre.
Five is reasonable watering. When watering vegetables, please pay attention to the amount of water should not be too large, avoid flood irrigation, it is best to use micro irrigation. After watering, when the soil is dry and wet, pay attention to plowing the soil in time.
