Abstract:
Amur Oblast in Russia is adjacent to Heilongjiang Province in China,both of them are the most important soybean production areas in two countries,and since the agricultural ecological environment of the two regions is similar,the soybean production experience of the two regions has the value for mutual learning.This article introduced the distribution of soybean varieties in Amur Oblast,Russia in the past 7 years,provided the proportion of local varieties in Amur Oblast,foreign varieties and non-variety soybeans planted in the region,and discussed the related issues of the unreasonable planting proportion of varieties in Amur Oblast.In Amur Oblast,the planting proportions of early-maturing,middle-maturing and late-maturing varieties were 31.1%,49.6%,and 7.6%respectively.Therefore,the article recommend choosing high-quality varieties suitable for local climatic conditions in soybean planting,implementing a scientific crop rotation system to improve the local planting structure,increasing local seed production capacity,and providing growers with high-quality and lowcost seed materials.
