It is extremely difficult to cure dead vegetables. How to prevent dead vegetables?

Dead plants often occur in vegetable cultivation. To increase soil permeability and prevent dead vegetables, the following points must be done:

Dead vegetables

First, the soil is turned deep. Before planting vegetables, be sure to dig deep into the soil. It is best to dig deep into the 30cm with a shovel, and then use a rotary tiller to fine the soil. This kind of soil is permeable and permeable, and it is beneficial to the deep root system of vegetables.

The second is to increase the application of organic fertilizer. The soil organic matter is insufficient but the chemical fertilizer is overused, the soil is easy to solidify and the air permeability is poor. Therefore, the air permeability of soil can be improved and the soil properties can be changed by increasing the application of organic fertilizer. 15ml / mu chicken manure can be applied according to vegetable varieties.

The third is to change the cultivation mode. Improving the air permeability of the soil can also be achieved by changing the cultivation methods, such as ridging cultivation, because the ridge soil is watered in the ridge and furrow, so the permeability of the ridge soil is good, and the temperature increases obviously. On the other hand, the soil at the root of trench vegetables is often irrigated by water, and the air permeability becomes worse, which is easy to cause retting roots. Therefore, ridging is advocated to cultivate vegetables.

The fourth is the use of biological fertilizer. The biological bacteria in biological fertilizer will multiply in large numbers after entering the soil, which can activate and loosen the soil, improve the soil structure and increase the soil permeability. The basic application of biological fertilizer can be 150 kg / mu or 200 kg / mu, or 25 kg / mu.

Fifth, rational watering. Usually watering vegetables must pay attention to the one-time watering should not be too large, do not flood irrigation, preferably micro-irrigation. After watering, when the soil is dry and wet, ploughing and loosening the soil in time can increase the air permeability of the soil.
