(黑龙江省农业科学院、东北农学院合作試驗) 为了要在大豆栽培方面深入貫彻农业“八字宪法”需了解大豆各主要性状对不同栽培条件的反应,从而确定符合农业“八字宪法”要求的栽培方法和品种类型。本試验利用我省新推广的及有希望的新品种,探討不同类型的大豆品种在两种不同密度,两种不同肥力条件下的反应,以便从大豆的生物学特性来了解不同类型的大豆品种,对密植的适应性以及在进行合理密植情况下的适宜种植方法,并为确定新品种的选育目标提供依据。同时对大豆落花落莢情况进行初步观察与分析,探索爭取大豆提高产量的途徑。
(Heilongjiang Academy of Agricultural Sciences, Northeast Agricultural College Cooperative Experiment) In order to thoroughly implement the “Eight Character Constitution” in soybean cultivation, it is necessary to know the reaction of the main characters of soybean to different cultivation conditions so as to determine the cultivation that meets the requirements of the “Eight Character Constitution” of agriculture Method and variety type. In this study, we used the new and promising new varieties in our province to explore the response of different types of soybean varieties under two different densities and two different fertility conditions to understand the different types of soybean varieties from the biological characteristics of soybean , The adaptability to close planting and the suitable planting methods in the condition of reasonable close planting, and provide the basis for selecting the breeding target of new varieties. At the same time, the preliminary observation and analysis on the situation of falling and falling of soybean were explored and the ways to gain the yield of soybean were explored.
