摘要
2005~2006年,对双免耕(早晚季免耕)、单免耕(晚季免耕)以及常规耕作的水稻进行了连续2 a 4季的生长和产量比较试验。结果表明:免耕与常规耕作在水稻生育期、经济性状和产量等方面无显著性差异。免耕栽培具有减轻劳动强度和缓解双抢期间季节紧、劳力缺等优势,且每季可节本增收229.5~627.0元/hm2。水稻免耕具有较好的推广前景,其中单免耕最值得推广。
Zero-tillage on early season rice and the 2006. The results showed that there is no significant second season rice yielding were tested respectively in 2005 and difference between zero-tiUage and the conventional tillage and the zero-tiUage can reduce labor and economic investment dramatically. So it is perspective to extension the zero-tillage method, especially the one season zero-tillage method.
