In planting vegetables, there are often dead tree phenomenon, increase soil permeability to prevent vegetables dead trees, must do the following:
One is to pay attention to the deep turning of 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 pay attention 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, the application of organic fertilizer is an important measure to improve soil permeability and change soil properties. It can apply chicken manure 15-25 squares per acre basis.
Third, pay attention to changing 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. The ditch planted vegetable root soil is often poured into the water, the permeability is poor, and it easily causes roots. Therefore, in vegetable cultivation, we must promote ridge cultivation. Conditional drip irrigation water is better.
Fourth, pay attention to the use of biological bacterial fertilizer. After being applied into the soil, the biological bacteria in the biological fertilizer will multiply in the soil and play a 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. Can be 150-200 kg of biofertilizer per mu, or 25-30 kg per mu.
Fifth, pay attention to reasonable watering. Vegetables usually watering must pay attention to the amount of watering should not be too large, should not flood irrigation, the best conditions for the use of micro-irrigation. After watering, when the soil is dry and wet, pay attention to timely cultivating loose soil, so that the air permeability of the soil will be good.
