水稻无纺布育秧抛栽具有省种、省工、免用秧盘的优点,增产增收效果明显,比对照增产7.8%,比迟播10天的塑盘育秧抛栽处理增产11.6%。主要原因是无纺布育秧提高了水稻的秧苗素质,在假茎高、假茎宽、单株根数和秧苗分蘖率等方面均优于对照,抛后分蘖早、分蘖多、够苗早。秧苗素质的高低与单位面积的有效穗数和水稻的产量成正相关。由于无纺布育秧的秧龄弹性大,对晚稻培育适龄老壮秧、抢季节、避过“寒露风”危害更为有利。
Rice non-woven seedling throwing planting has the advantages of provincial species, provincial workers, free seedling tray, yield increase effect is obvious, yield 7.8% more than the control, than the late sowing 10 days of plastic disc seedling throwing treatment yield 11.6%. The main reason is that non-woven seedling raising rice seedling quality, in the pseudostem height, pseudostem width, root number per plant and seedling tillering rate and other aspects are better than the control, throwing early after tillering, tillering and more seedling early. The level of quality of seedlings and the effective panicles per unit area and rice yield is positively correlated. As the non-woven seedling seedling elasticity, cultivating late rice seedling age, old age, to avoid the “cold dew wind,” the more dangerous harm.
