How to treat continuous cropping diseases in vegetables? These control methods are very practical
The development of greenhouse production has brought obvious economic benefits to farmers, but after greenhouses have been used for many years, various diseases, especially soil-borne diseases, have become increasingly serious, and this has become a problem that must be taken seriously in greenhouse vegetable production. The best way to solve continuous cropping disease is to adopt comprehensive measures. So today let us take a look together at how to treat continuous cropping diseases in vegetables?
1. Implement crop rotation
According to the requirements of different vegetable crops, plant again after a certain interval. Crop rotation is effective in preventing soil-borne diseases.
2. Use compound fertilizer reasonably
Do not use it excessively. It can be used together with macro-element water-soluble fertilizer. It is recommended to apply it in small amounts many times. In the early stage, focus on balance to promote growth. In the later stage, choose a high-potassium water-soluble fertilizer according to the situation. A liquid-based clear water-soluble fertilizer is better.
3. High-temperature greenhouse sealing
High-temperature greenhouse sealing is an economical and effective method to prevent continuous cropping diseases in vegetables, that is, using high temperature from solar energy for treatment, disinfection and sterilization. The specific method is to carry out the treatment during the high-temperature stage from June to September each year, generally from early July to late August. It has low cost, little pollution, simple operation and good effect.
4. Supplement beneficial microbial communities
Sufficient soil nutrients are one aspect, and the content of good beneficial microbial communities is also very important, but when we apply microbial agent fertilizer by flushing, soil problems cause the survival rate of beneficial microbes to decline. In addition, some microbial agents do not have a combination that can eliminate harmful pathogens, so the effect after use is poor.
