水稻旱育稀植机械插秧效率高（１）优点①秧苗通风透光性能好、营养面积合理，故抗病虫灾能力强。②缓秧快、成活率高。③分菜早、分率节位低１～２个，分莱数量比手工多约一倍，每株可达２０～３０棵。④育秧期比手工秧苗缩短１５天左右，播种效率比手工提高３～７倍。如... Rice dry and fertile planting mechanical transplanting efficiency (1) Advantages ① seedling ventilation and light performance, nutritional area is reasonable, so the ability of resistance to diseases and pests. ② slow seedling fast, high survival rate. Â ’¢ sub-dish early, low rate of node 1 to 2, the number of sub-Lai about twice as much, up to 20 to 30 trees per plant. ④ seedling shorter than hand-made seedlings about 15 days, sowing efficiency increased by 3 to 7 times more than manual.
