摘要
采用裂裂区试验设计,对丘陵区麦茬水稻免耕技术进行了研究。试验结果表明,免耕与翻耕相比,分蘖快,根系活力强,功能叶面积大,提高了产量构成因素水平,增产极显著。在本试验条件下,麦茬水稻免耕技术适宜于不同施氮水平和施肥方法采用。
The ploughing-free technology of planting ride after wheat in hill-region was studied by means of the split-split plot design.The results of the experiment showed that several facfors affecting rice yield with ploughing-free were superior to with ploughing.The ploughing-free technology was suitable for different methods of applying fertilizer and levels of applying nitrogen.
