1986～1990年我们进行了夏大豆品种、密度、施肥、灌水等主要栽培措施与综合丰产的研究与应用,认为菏泽地区夏播大豆由于可供其生长的时期相对较短,以选用生育期100天左右,株形紧凑的品种,适当增加密度,较易获得每亩200kg以上的稳定产量。栽培措施要点是:以增加群体密度、采用氮磷配合施用;有机肥、无机肥与微肥配合施用,以提高光合与固氮能力,并使植株生长稳健、营养与生殖生长协调,促进养分向生殖器官输送。花荚期叶面施肥与结荚、鼓粒期迂旱浇水,延长叶片与根瘤的功能期,使养分充分运入籽粒,以提高粒重,充分发挥大粒品种籽粒的养分贮藏功能。
From 1986 to 1990, we carried out the research and application of major cultivation measures and comprehensive yield cultivation of summer soybean such as summer soybean, density, fertilization and irrigation. It is concluded that the summer sowing soybean in Heze region has a relatively short period of growth because of its relatively short period of growth, Days or so, compact plant varieties, an appropriate increase in density, more easily get 200kg per acre stable output. Cultivation measures are: to increase the density of the population, the use of nitrogen and phosphorus with the application; organic manure, inorganic fertilizers and trace fertilizers with the application in order to improve photosynthetic and nitrogen-fixing capacity, and plant growth and stability, nutrition and reproductive growth and coordination, and promote nutrient to reproductive Organ delivery. At the stage of flowering and podding, foliar fertilization and podding were carried out, and the watering period was prolonged at the stage of druming, prolonging the functional period of leaves and nodules, and the nutrients were fully transported into the grains to enhance the grain weight and give full play to the nutrient storage function of large grain varieties.
