1、适时移栽。苗龄达40天左右移栽,密度26厘米×33厘米,每亩大田栽7000株左右。2、施足基地。无论直播或移栽,每亩大田施尿素20~30公斤或碳铵60.公斤,磷肥20公斤,氯化钾7.5公斤,硼砂0.5公斤。3、化学除草。移栽或直播完毕后,每亩用乙草胺50毫升兑水60公斤均匀喷雾。 1, timely transplanting. Miao age of about 40 days transplanting, density 26 cm × 33 cm, planting about 7000 plants per mu field. 2, Shi enough base. Whether live or transplanted, 20 to 30 kg of urea or ammonium bicarbonate per acre field 60 kg, phosphate fertilizer 20 kg, potassium chloride 7.5 kg, borax 0.5 kg. 3, chemical weeding. Transplanting or broadcast after the completion of each acre with acetochlor 50 ml watered 60 kg uniform spray.
