抛秧比常规栽培增产5％～9％,每公顷可省40～50工日,节省秧田开支300～400元,因增产节本,每公顷可净增收入1500～1600元。 一、育秧 1.育秧准备。杂交稻每667平方米需561孔塑料软盘40张,每盘播干种子45克左右。将已冻化、过筛的优质肥土与优质农家肥,按土肥比7:3混合,每500公斤混合土加硫酸铵0.5公斤、过磷酸钙1.3公斤、硫酸钾0.5公斤充分混合,制成营养土,用100公斤水拌15公斤营养土搅成泥浆浇
Seedling throwing than conventional cultivation yield 5% to 9% per hectare can save 40 to 50 days, save 300-300 yuan seedling expenses, due to the increase in production cost, net income per hectare 1500 ~ 1600 yuan. First, seedlings 1. Nursery preparation. Hybrid rice per 667 square meters to be plastic plastic disk 561 holes 40, about 45 grams per dish dried seeds. Will have been frozen, sieved quality fat soil and high-quality manure, according to fertilizer than 7: 3 mixed, 500 kg of soil mixed with 0.5 kg of ammonium sulfate, superphosphate 1.3 kg, 0.5 kg of potassium sulfate were mixed to prepare Nutrient soil, with 100 kg of water mixed with 15 kg of nutrient mud stirring mud pouring
