摘要
20 0 2年早造对比试验 ,稻草还田免耕抛秧区平均每 hm2 产量为 7818.0 kg,稻草不还田免耕抛秧区为7716 .0 kg,翻耕耙沤抛秧区 732 4 .5 kg。稻草还田免耕比不还田免耕增产 1.32 % ,比翻耕增产 6 .74 %。
Three cultivation methods of contrast experiment were carried out in 2002. The average yields, respectively, were 7818.0 kg per hm 2 for the nontillage with straw remaining in field, 7716.0 kg per hm 2 for the nontillage without straw remaining in field and 7324.5 kg per hm 2 for the tillage without straw remaining in field. In comparison with the second and third methods, the first one increased 1.32% and 6.74% in yield, respectively.
