Soil-borne diseases are a common disease in vegetable cultivation. They usually endanger the roots and stems of plants. Once the disease occurs in the early stage of vegetable growth, the roots of the seedlings rot or the stems rot and fall, the seedlings will soon die, seriously affecting the crops. Growth requires timely prevention. Next, Huinong.com will share with you how to prevent and cure vegetables.
First, soil disinfection
1. Lime disinfection: Lime can both sterilize and neutralize the acidity of the soil.
2. Large water soaking: Where there are conditions, you can use the crop leisure season to block the water and soak the soil. The longer the soaking time, the more obvious the effect. If soaked for more than 20 days, the nematode hazard can be basically controlled.
3. High-temperature disinfection: greenhouse greenhouses in the summer high temperature season, the soil can be ploughed, covered with mulch, and then covered with a film, the ground temperature can reach 50 ° C or more to kill some of the bacteria.
4. Disinfection of the medicament: The soil can be disinfected with the medicament before sowing.
Second, the selection
The selection of disease-resistant or disease-resistant varieties can greatly reduce the degree of damage caused by soil-borne diseases.
Third, the implementation of rotation
This is the most cost-effective measure to prevent soil-borne diseases. Reasonable crop rotation, especially water and drought rotation, can have a multiplier effect on preventing the occurrence of soil-borne diseases.
Fourth, improve cultivation measures to prevent disease
1. Deep sorghum cultivation, small water pouring, avoid flooding.
2. Reasonable close planting, improve the ventilation and light transmission conditions of the crop, and reduce the ground humidity.
3. Clean the garden, remove the diseased plants, and apply lime in the diseased plant.
4. Avoid partial application of nitrogen fertilizer, it is best to increase the application of organic fertilizer to improve crop disease resistance.
5. Foliar spray instead of root top dressing, crop growth period can be combined with application of spraying Jiameijin point, melatonin.
6. Grafting and disease prevention, grafting roots with disease-resistant rootstocks can effectively prevent the occurrence of soil-borne diseases.
Vegetable soil-borne diseases are not terrible. As long as we do a good job of prevention in advance and pay attention to the hazards of pests and diseases, we will certainly increase the production and income of vegetables.
