摘要
连续多年多点的小区试验、大区定位试验和高产示范结果表明 ,稻茬麦实行免耕抑播稻草覆盖栽培具有显著的省工、节本、增产、增收效应 ,一般比撬窝点播栽培省工 4 6 3% ,节本 2 0 6 % ,增产 6 %～ 7% ,增收 2 7 5 % ;比旋耕机播栽培省工 19 1% ,节本 2 6 3% ,增产 9%～ 12 % ,增收4 8 8%。对后作水稻也有明显的增产作用 ,一般增产 3%～ 6 %。
A series of experiments on sowing practice for wheat establishment after rice in 1991～2000 were conducted and the results showed as followings:the technology of surface seeding and mulching rice straw for wheat after rice reduced labor and input value and increased grain yield and income significantly.Compared to the seeding by digging holes,it saved labor by 46 3% and cost by 20 6%,and increased yield by 6%～7% and income by 27 5%.Compared to the cultivation of mechanical sowing under rotary tillage,it saved labor by 19.1% and cost by 26.3%,and increased yield by 9%～12% and income by 48.8%.Besides,it also increased subsequent rice yield by 3%～6%.
