How to choose high-oil soybean

The contribution rate of high-yield varieties in general production accounts for about 30% to 40%. In the production of high-oil soybeans, the contribution rate of high oil varieties can reach over 80% in terms of the oil content of products. In recent years, driven by the implementation of the soybean revitalization program by the Ministry of Agriculture, a series of high-oil soybean varieties have been bred in succession in China, especially in the Northeast soybean production area. However, due to the different ecological conditions in the producing areas, the maturity types of different high-oil soybean varieties vary greatly, resulting in a significant change in yield between different regions and years. Therefore, it is entirely possible to rationally select high-oil varieties that are compatible with local ecological conditions, and to support practical high-yielding cultivation patterns and technical measures to increase production. It is entirely possible to increase the current high-oil soybean production level and overall quality in a short period of time. feasible. According to local production practices, the selection of high-yield soybeans for high-yield cultivation should follow the following principles: The maturity of the varieties is appropriate, and it is a measure of whether the accumulated temperature before ripening, the number of breeding days, and the ripening period are similar to the local main cultivars. The main criteria for the appropriate maturity of varieties. Among them, the ripening period is similar to the standard of the local cultivars. It is more accurate and reliable. Because soybean growth is more sensitive to light, the accumulated temperature and number of fertility days is only a relative average of fertility performance in specific areas, and often varies depending on the year and place. In addition, the coordinated development of the variety development process and climate seasonal changes is also one of the prerequisites for achieving high oil-yielding soybean production. Variety oil content rate High soybean oil content should be more than 20%, high oil soybean should be more than 22%, pure grain rate of more than 98%, the former can meet the first-class standards, the latter up to special standards. At present, under the circumstance that high-oil soybean varieties are valued, exaggerating the oil content of the varieties or over-emphasizing the high oil content should avoid misleading production. High yield potential, adaptability, and high yield. The selection of high oil varieties cannot ignore the yield potential of varieties, which is one of the prerequisites for the formation of high yields. Due to the different utilization and adaptability of different varieties to the local conditions such as fertilizer and water, they will also show different characteristics in the growth and development, and ultimately cause significant differences in the high yield of the varieties. Only according to the actual conditions of local soil fertility and water conditions, select varieties with strong adaptability, good yield and stability, in order to fully tap the high-yield potential of the high-oil varieties themselves, and realize more significant increase in production. Varieties resistant to pests and diseases High oil-yield Soybeans High-yielding cultivation should also emphasize the variety's resistance to pests and diseases. Because pests and diseases can not only reduce the appearance of commodity soybean quality and oil content, serious damage will also cause soybean fertility disorders and significantly reduce production. Variety resistance to pests and diseases can also effectively reduce control operations and reduce production costs. In addition, the selection of pest-resistant varieties is the basis and prerequisite for the production of pollution-free (green or organic) soybeans, which directly determines whether commodity soybeans can meet pollution-free (green or organic) product standards.
