How to prevent yield reduction during wheat harvest?
How to prevent yield reduction during wheat harvest? What factors will lead to a reduction in production?

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 economy of farmers.

Yield reduction reasons and yield protection techniques of soybean continuous cropping cultivation
The main results are as follows: 1. the reasons for the yield reduction of continuous cropping soybean are slow growth, dwarfism, yellow leaf color, few pods and few seeds, resulting in a significant decrease in yield. In the short term, continuous cropping will aggravate the harm of cyst nematode, root maggot, root rot, heart borer, gray spot and malignant weeds, and the partial consumption of soil nutrients, resulting in the deficiency of soil nutrient elements and the increase of pathogenic fungi in soil. the number of beneficial bacteria decreased, and some toxins were produced, which led to a serious decline in soybean yield and quality. In the long run, after long-term accumulation and reproduction, diseases and insects

Great progress has been made in the project of "controlling soybean continuous cropping and reducing yield".
The reporter learned from the relevant departments that the project "Research and demonstration of key Technologies for controlling Soybean continuous cropping and yield reduction" invited by the Municipal Science and Technology Bureau has made significant progress after two years of scientific research. The project was carried out in Yilan and Bayan counties with the largest soybean area in Harbin. Through the study of key technologies, soybean varieties resistant to continuous cropping, such as Kenfeng 16, Heinong 48, Kangxian 4 and Hefeng 47, were selected. It was proposed that 45 kg of nitrogen, 60-67.5 kg of phosphorus, 67.5-75 kg of potassium per hectare were applied.
