不同熟期类型大豆品种都在中等或较高密度种植条件下表现出比在低密度种植条件下更高的产量,即密植比稀植更加增产;不仅早熟、中早熟类型大豆品种宜密植,而且中晚熟类型大豆品种也同样喜欢较高的密度,这与过去的观点\\\"早熟宜密,晚熟宜稀\\\"相左。本文结果认为在大豆生产中应该坚持\\\"适度密植,宁密勿稀\\\"的原则。
Different maturity soybean varieties showed higher yield under medium or higher density planting conditions than under low density planting conditions, that is, close planting increased more yield than thin planting; not only the early-maturing and middle-early maturing soybean varieties should be close planting, but also The same type of late-maturing soybean also like the higher density, which is the past point of view \\ \"precocious should be close, late maturing should be diluted \\\". The results of this paper believe that in the production of soybeans should adhere to \\ \"moderate density, rather than dense \\\" principle.
