前期较早形成较繁茂的营养体,而后期相对来看又不过份郁闭的群体长势,有利于通风透光,光合效益高,是高产型长相和结构形式;就一般年份来说,限制黑龙江省大豆生产的主要气象因子是水分,窄行距大豆地块有利于保水;黑龙江省现有的几个大豆品种,最大叶面积指数在6左右、密度在35～45万株/公顷情况下,株间微气象环境较为适宜,大豆产量高;倒伏对大豆产量和品质有严重影响,垅作能相对减轻倒伏程度,而且垅作比平作能相对提高地温。
The early formation of a more prosperous nutrition body, while the latter relatively not over-crowded population growth, is conducive to ventilation and light, photosynthetic benefits, is a high-yielding appearance and structure; for the general year, the restrictions on Heilongjiang The main meteorological factor of soybean production is water, and the narrow row spacing of soybean plots is conducive to water conservation. The existing soybean varieties in Heilongjiang Province have a maximum leaf area index of about 6 and a density of 350,000 to 450,000 plants per hectare. Between the micro-meteorological environment is more appropriate, high yield soybean; lodging on the yield and quality of soybeans have a serious impact on the lodging can reduce the relative degree of lodging,
