三江平原是全国大豆生产基地之一,历年种植面积占耕地面积的30%左右。为提高单产,从1987年开始,黑龙江省科委组织我所在三江平原宝清县开展大豆大面积高产高效益试验示范,3年累计试验示范面积60万亩,平均亩产177.1公斤。总结关键栽培技术如下:一、选用良种,合理密植大豆高产最首要的是选用适合当地土壤气候特点、丰产性能好、抗逆性强、成熟期适宜的品种。据此, Sanjiang Plain is one of the national soybean production bases, and the cultivated area over the years accounts for about 30% of the cultivated land area. To improve yields, from 1987, Heilongjiang Provincial Science and Technology Commission organized a demonstration experiment on large-area, high-yield and high-yield soybean in Baoqing County, where is located in Sanjiang Plain. The demonstration area of ​​three years of accumulated experiments was 600,000 mu with an average yield of 177.1 kg per mu. Summarize the key cultivation techniques are as follows: First, the selection of elite, close planting rational soybean density The most important choice is suitable for the local climate characteristics of the soil, high yield performance, strong resistance, maturity suitable varieties. Accordingly,
