为解决免耕抛秧技术需大量使用农药和除草剂的缺点，将稻田围栏养鸭引人免耕抛秧技术．试验结果表明，与翻耕相比，本技术体系无须使用农药和除草剂而能有效地控制杂草和病虫害，有利于改善农田生态环境，而且生产了无污染的生态米和生态鸭．有效穗数每公顷增加了6×10~4穗，单产增加了141 kg／hm~2；免耕抛秧养鸭比翻耕每公顷节约农药、除草剂费用320元，节约机耕费用600元，农民增加纯收入4 390元，经济效益显著．

In order to overcome some negative effects on ecological enviroment because of much application of pesticide and herbicide by notillage casttransplanting technique, this expriment introduces duckraising in enclosed paddy fields into notillage casttransplanting technique. The result shows,compared with tillaging,it can control plant deseases and insect pests and weeds effectively without using pesticide and herbicide. Futhermore, it not only improves the yield character and increases grain yield by 114 kg·hm-2, but also decrease...
