在1981—1985年对三江平原上种植旱作大豆的高产技术配套体系进行研究,先后在牡丹江、红兴隆、建三江等三个国营农场管理局、十二个农场、三十七个生产队,一百多个点次进行了大面积示范和推广,经过不同旱涝灾害,不同土壤类型的考验。大面积生产实践验证;大豆高产技术配套体系,改善了土壤理化性质,扩大土壤生态容量,解决了缺苗断条,满足大豆整个生育期对养分的需要,增强抗旱,抗涝,抗病虫害能力。结果:五年累计种植面积46万多亩,其中示范面积8.3万亩,平均亩产176.15公斤,每亩比相临对照增加55.7公斤,增产46.2％:每亩比对照增收30.9元,增值80.9％。推广面积38.1万亩,平均亩产137.6公斤,比相临对照增产19.2％;增收12.9元,增值28.1％。
From 1981 to 1985, we studied the high-yielding technology supporting system for planting dry soybean in the Sanjiang Plain. In three state-owned farms, including Mudanjiang, Hongxinglong and Jian Sanjiang, the three farms, twelve farms, 37 production teams, More than 100 points were carried out a large area demonstration and promotion, after different droughts and floods, different types of soil test. Large-scale production practice verification; soybean high-yielding technology supporting system, improving the soil physical and chemical properties, expanding soil ecological capacity, to solve the lack of seedlings broken to meet the needs of nutrients during the whole soybean growth and enhance drought, waterlogging, pest and disease resistance capabilities. Results: The total acreage of the five years was 460,000 mu, of which the demonstrative area was 83,000 mu and the average yield per mu was 176.15 kg. The acreage increased 55.7 kg and 46.2% respectively compared with the corresponding control. The acreage increased 30.9 yuan and the value added 80.9% . The promotion area is 381,000 mu, with an average yield of 137.6 kilograms, an increase of 19.2% over the previous comparison; an increase of 12.9 yuan and an added value of 28.1%.
