How to prevent and cure garlic replanting

Garlic has a large planting area in all parts of our country. The planting method of garlic is relatively simple, and the yield is relatively high. However, there are many farmers in the planting of garlic, because of continuous cropping will appear the harm of continuous cropping. The continuous cropping of garlic has a great effect on its yield and growth. So when we grow garlic, how to prevent garlic cropping? The following editor will give you a brief introduction, let's have a look!

1. Deep ploughing in rotation

If you want to prevent and cure garlic cropping, then rotation is the simplest and most effective way. When growing garlic, we should rotate with vegetables such as celery and kale. If the disease is serious, then at least 2-3 years of crop change can be replanted, and the role of crop rotation can be achieved by planting large banners intercropping some overwintering vegetables. Then we have to do a good job of deep ploughing, to break the plough bottom of the soil, and the depth of ploughing should be kept at about 25cm. Then fine soil preparation can improve the degree of soil activation and reduce the base number of bacteria and eggs in the soil.

2. Rational fertilization

Reasonable application of organic fertilizer and returning straw to the field can also effectively prevent the harm of continuous cropping of garlic. Garlic per mu should be applied high-quality farm fertilizer 5000kg, with appropriate amount of chicken and duck manure and grain straw and so on. In this way, it can effectively improve the soil structure and improve the water and fertilizer conservation capacity of the soil. When we are fertilizing, it is best to test the soil and distribute fertilizer. By examining the nutritional structure of the soil, according to the nutrient content of the soil, supplement the lack of nutrients in the soil, use chemical fertilizer reasonably and scientifically, and reduce the harm of repeated cropping of garlic.

3. Apply biological bacterial fertilizer.

Biological fertilizer is very beneficial to the growth of garlic. Because after entering the soil, biological bacteria will compete for growth nutrition and space with pathogens, which will antagonize each other. Therefore, it can also effectively reduce the number of pathogens in soil. Keep microbes, soil, etc., in a state of equilibrium with the roots of garlic. The organic matter in biological fertilizer can also increase the content of organic matter in soil, improve the structure of soil aggregates and improve soil permeability. Provide sufficient nutrition for the growth of microorganisms and promote the growth and reproduction of microorganisms.

4. Chemical control

Before sowing garlic, we should apply seed dressing, disinfection and accelerate germination of garlic seeds. It can be evenly mixed with water and seeds with Dorning powder, and then sowed after being stuffed for about 6 hours. Then we mix the fine soil with carbendazim and Donin powder and spread the fine soil evenly on the surface before sowing. In addition, we also need to carry out targeted drug control according to the types of diseases in the planting. For example, if leaf blight occurs, chlorothalonil can be used for control to ensure the healthy growth of garlic.

The above is a brief introduction to how to prevent garlic cropping. That's all for today's introduction. This article is for reference only. I hope it can help you all.
