摘　　要：水稻具有较强的自动调节能力，通过稀播、稀植提高有效分蘖率，有效穗数中明显提高二次分蘖数，同时稀植增加了二次枝梗数，从而增加了每穗粒数，进而增加水稻产量。稀植的水稻由于自动调节，缩短茎基部节间长度，拉长茎上部的节间长度，增加折损重，提高抗倒伏能力。Rice has strong automatic regulation ability. Thin planting increases effective tiller rate, raises two times tiller number of available spike, increases two times branch stalk number, so increases rice yiel. Because of automatie regulation, its bottom internode becomes short and thick, its upper elongative internode becomes long, increasing the weight of breakage loss, enhancing capability for the resistance of lodging.
