水稻免耕栽培的减灾效应研究

Effect of Rice No-tillage Culture on Disaster Reduction

为探索稻田保护性耕作技术——水稻免耕的减灾效应,将免耕与传统稻作方法相结合组成常耕移栽、常耕抛秧、免耕移栽、免耕抛秧4个处理进行试验,并运用生态学原理对试验结果进行了分析研究。结果表明,稻田保护性耕作能提高作物产量,降低部分生育期间水稻病虫害,抑制农田杂草的生长。

In order to explore the effects of the conservation tillage technology of paddy field, rice no-tillage Culture, on disaster reduction, this research combines it with the traditional tillage technology into 4 processes, traditional tillage transplant, traditional tillage cast-transplant, no-tillage transplant and no-tillage cast-transplant, to experiment and analyze them using ecological principle. The results indicate： （1） The yield can be increased; （2） The conservation tillage can reduce partial paddy disease and insect pest during winter wheat growing period; （3） The conservation tillage can inhibit the growth of weed.
