一般生产上良种的贡献率约占30％～40％,而在高油大豆生产中,从商品含油率看,高油品种的贡献率可以达到80％以上。近年来,在农业部实施大豆振兴计划的带动下,我国特别是东北大豆产区已相继育成了一批高油大豆新品种。但由于产区生态条件的不同,不同高油大豆品种熟期类型差别较大,导致在不同地区和年份间产量变化也非常明显。 因此,合理选用与当地生态条件相适应的高油品种,并配套实用的高产栽培模式和技术措施来增加产量,对于较短时期内提高目前东北高油大豆生产水平和整体品质,是完全可能和可行的。通过各地的生产实践来看,高油大豆高主栽培的品种选用应遵循以下几项原
In general, the contribution of elite seeds is about 30% to 40%. In high-oil soybean production, the contribution rate of high oil varieties can reach more than 80% from the perspective of the oil content of the products. In recent years, driven by the implementation of the soybean revitalization plan by the Ministry of Agriculture, a number of new varieties of high-oil soybean have been bred in China, especially in the northeast soybean producing areas. However, due to the different ecological conditions in the producing areas, the maturity types of different high-oil soybean varieties are quite different, resulting in obvious changes in production in different regions and years. Therefore, it is quite possible to rationally choose the high-oil varieties suitable for the local ecological conditions and to support the practical high-yield cultivation modes and technical measures to increase the output so as to increase the production level and overall quality of the Northeast high oil soybean in a relatively short time feasible. Through the production practices around the point of view, high oil cultivation of soybean varieties should follow the following principles
