What to Do About Soybean Yield Loss from Continuous Cropping? Latest Control Measures Explained
Soybean, as one of China's main food crops, has a very large market demand in our country. There are also many people who grow it, but many people do not pay attention to the problem of continuous cropping when growing soybeans. This leads to yield loss from continuous soybean cropping and seriously affects farmers' economic benefits. Therefore, continuous soybean cropping is something we need to pay close attention to. So how can we prevent yield loss from continuous soybean cropping? Let's take a look together below!
1. Crop rotation control
Soybean is a crop that is not suitable for continuous cropping, so if we want to prevent yield loss from continuous cropping, then first of all we need a reasonable crop rotation system. This is the most basic and also the most effective measure for reducing yield loss from continuous soybean cropping. When we grow soybeans, the area should not exceed 1/3 of the grain area, and reasonable rotation should be carried out. In the soil plow layer, deep plowing should be carried out, combining loosening, turning and harrowing, to improve the soil structure and create a good growing environment for soybeans. For the plot, do not choose soil that has been continuously cropped, is barren, or is low-lying, so as to ensure soybean yield.
2. Variety control
Variety is very critical to the growth and yield of soybeans, and choosing a good variety is also a main measure for reducing the harm of continuous soybean cropping. Soybean seeds must be plump, without wounds, and free of pests and diseases. Before sowing, seed dressing can be done with agents such as amino-oligosaccharin, which can effectively increase the emergence rate of soybean seeds and enhance their immunity. There have also been professional data surveys showing that it is not only by renewing the planted variety that the harm of continuous cropping can be reduced. Even if it is the same variety, then appropriate replacement can also achieve the effect.
3. Nutritional control
When we grow soybeans, fertilization work is very important. Appropriately increasing the application amount of beneficial fertilizers such as organic fertilizer, biological fertilizer, and biological bacterial fertilizer can effectively reduce the harm caused by continuous cropping. For example, the amino-oligosaccharin just mentioned can improve soil fertility, break up soil compaction, enrich the nutrient structure in the soil, promote healthy development of soybeans, enhance the stress resistance of soybean plants, and increase their yield. As for microbial inoculants, they can increase soil activity, regulate the pH inside the soil, and ensure normal growth of soybeans.
4. Pest and disease control
In soil under continuous soybean cropping, the number of pests in the soil is very large. Pests are also a main cause of soybean yield loss, so if we want to reduce the harm of continuous soybean cropping, then pest and disease control work is naturally indispensable. We should thoroughly disinfect the soil, reasonably use insecticides, and carry out flushing application, foliar spraying, and so on. Do a good job in preventing pests such as root-knot nematodes to reduce pest harm.
The above is a brief introduction to the control measures for yield loss from continuous soybean cropping. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
