据统计，黑龙江省林区大豆种植面积约70万亩，占林区农田总面积的43．7×10－2，亩产90～130公斤．低于农场总局系统10．0×10-2左右；如与当今农业高科技种植亩产200～250公斤相比，则低55．0×10－2～75.0×10-2。究其原因主要是种植技术不更新，管理措施不科学。为了尽快提
According to statistics, the planting area of soybean in the forest area of Heilongjiang Province is about 700,000 mu, accounting for 43.7 × 10-2 of the total farmland in the forest area, with a yield of 90-130 kg per mu. Which is lower than the 10.0 × 10-2 system of the Farm Administration. If it is between 200 and 250 kg per mu in current high-tech agricultural farming, it will be 55.0 × 10-2 to 75.0 × 10-2 lower. The main reason is that planting technology is not updated, unscientific management practices. In order to mention as soon as possible
