One is to deepen the soil. Before the vegetable is planted, it is necessary to deep-deep the soil, it is best to use a shovel to deepen 30 cm deep, and then use a rotary tiller to thin. This soil is not only breathable and permeable, but also conducive to deep rooting.
The second is to increase organic fertilizer. The lack of soil organic matter and excessive use of chemical fertilizers often result in soil compaction and poor air permeability. Therefore, increasing organic fertilizer is an important measure to increase soil permeability and change soil properties. It can apply 15 to 25 cubic meters of chicken manure per acre based on the crop.
The third is to change cultivation methods. Changing the cultivation method can also improve the permeability of the soil. For example, ridge cultivation can be carried out in a furrow by watering, so the ridge surface has good air permeability and obvious temperature increase. However, the roots of the vegetables planted in the ditch are often contaminated with water and the permeability of the roots is deteriorated. This can easily cause roots. Therefore, in the cultivation of vegetables, ridge cultivation is advocated.
Fourth, pay attention to the use of biological bacterial fertilizer. After being applied to the soil, the biological bacteria in the biological fertilizer will multiply in the soil and play the role of activating and loosening the soil, which has a significant promoting effect on improving the soil structure and increasing the permeability of the soil. You can apply 150-200 kg of biological fertilizer per acre or 25-30 kg per acre.
The fifth is reasonable watering. Vegetables usually watering must pay attention to the amount of water should not be too large, should not flood irrigation, the best use of micro-irrigation. After watering, see the timely cultivating tillage when the soil is dry and wet.
