一、培育带蘖壮秧采用园田、旱田、庭院及稻田高台等各种开闭式全旱育苗。坚持稀播种、控温、控氮、控水的“一稀三控”培育壮秧方法。稀播种,在配制好营养土、细致做床的基础上,用精选种子,每平方米苗床播干籽150—180克,覆土、浇足底水和喷施除草剂后,用开闭式薄膜覆盖。控氮,防止氮量过多造成秧苗徒长,减弱抗逆力。底肥营养土每平方米不超过180克硫铵,三叶期追180克硫
First, nurturing strong growth with tiller Parkland, dry land, gardens and rice paddies and other high-profile open-cut dry nursery seedlings. Insist on thin sowing, temperature control, nitrogen control, water control, “a rare three control” to cultivate strong seedling method. Dilute sowing, in the preparation of good nutrition soil, meticulously on the basis of the bed, with a selection of seeds per square meter seedbed dry seed 150-180 grams, soil cover, pouring foot water and spraying herbicide, with the opening and closing type Film covered. Control of nitrogen, to prevent too much nitrogen caused seedlings lengthened, weakened the resilience. Fertilizer nutrition soil per square meter does not exceed 180 grams of ammonium sulfate, clover chasing 180 grams of sulfur
