The latest control measures for yield reduction of soybean in continuous cropping
As one of the main food crops in China, the market demand of soybean is very large in our country. There are also a lot of growers, but many people don't pay attention to the problem of continuous cropping when planting soybeans. It leads to the reduction of soybean yield after continuous cropping, which seriously affects the economic benefits of farmers. Therefore, soybean continuous cropping requires us to pay more attention, so how can we prevent soybean continuous cropping from reducing soybean yield? Let's take a look at it with the editor.
1. Crop rotation control
Soybean is an unsuitable crop for continuous cropping, so we want to prevent continuous cropping from reducing yield. Well, first of all, there must be a reasonable rotation system, which is the most basic and most effective measure to reduce the yield reduction of soybean continuous cropping. When we plant soybeans, the area of soybeans should not exceed 1x3 of grain area, and crop rotation should be reasonable. On the ploughing layer of the soil, it is necessary to turn it deeply and combine it with loosening and raking to improve the structure of the soil and create a good growth environment for soybean. The plot does not select continuous cropping, barren, low-lying soil to ensure soybean yield.
2. Variety control
Variety is very important for the growth and yield of soybean, and the selection of a good variety is the main measure to reduce the harm of soybean continuous cropping. Soybean seeds should be full, no wounds, no diseases and insect pests and so on. Before sowing, seeds can be mixed with amino oligosaccharins and other agents, which can effectively improve the emergence rate of soybean seeds and enhance their immune ability. There has also been a professional data survey phenomenon, not only the renewal of planting varieties can reduce the harm of repeated cropping. Even if it is the same variety, then the appropriate replacement can achieve its effect.
3. Nutritional prevention and control
When we are growing soybeans, fertilization is very important. Properly increasing the application amount of organic fertilizer, biological fertilizer, biological bacterial fertilizer and other beneficial fertilizers can effectively reduce the harm caused by continuous cropping. For example, aminooligosaccharides just mentioned can improve soil fertility, break soil consolidation, enrich soil nutritional structure, promote the healthy development of soybean, enhance the stress resistance of soybean plants, and increase its yield. The microbial agent can improve the activity of the soil, adjust the acidity and alkalinity of the soil, and ensure the normal growth of soybean.
4. Disease and pest control
In the soil of soybean continuous cropping, the number of pests in the soil is very large. And pests are also one of the main reasons for the reduction of soybean production, so if you want to reduce the harm of soybean cropping, then pest control work is indispensable. We carry out comprehensive and thorough disinfection of the soil, rational use of pesticides, flushing application, leaf spraying and so on. Do a good job in the prevention of root-knot nematodes and other insect pests to reduce the harm of insect pests.
The above is a brief introduction to the prevention and control measures of soybean continuous cropping. That's all for today's introduction. This article is for reference only. I hope it can help you all.
