我场十队,1988年应用大豆双行精量点播机,播种大豆1500亩,增产18.7～20.6%,每亩增产大豆为41～42.4公斤,共增产大豆6万公斤,每亩纯收益33.3元。实践证明,大豆双行精量点播是一项挖掘大豆增产潜力的好措施。它具有单株分布均匀,群体结构合理,提高吸肥、吸水、抗旱能力,节省种子、降低成本的作用。在应用中应注意以下几个问题:
I field ten teams, in 1988 the application of double-precision sowing machine soybeans, sowing 1500 acres of soybean, an increase of 18.7 ~ 20.6% yield per acre soybeans 41 ~ 42.4 kg, a total of soybean yield 60,000 kg, 33.8 yuan net profit per acre . Practice has proved that the quality of dual-line soybeans on-demand is a good measure to tap soybean production potential. The utility model has the advantages of uniform distribution of individual plants, reasonable population structure, enhancement of ability of absorbing fertilizer, absorbing water and drought, saving seeds and reducing cost. In the application should pay attention to the following questions:
