本研究通过开展不同覆盖物对水稻旱种的影响实验得出,覆盖旱种水稻能提高水稻的成穂率,减少水稻的空壳现象发生;在提高成穗率和降低秕谷率方面,覆膜覆盖旱种效果较优;在水资源短缺的地区,使用覆草覆盖旱种技术,是提高当地水稻产量和保持生态环境的首选。 In this study, we conducted experiments on the effects of different coverings on the dry cultivation of rice. It was found that covering dry-cultivated rice could increase the yield of rice and reduce the occurrence of shell-emptying in rice. It is better to cover the dry farming species. In areas with a shortage of water resources, the use of mulching and covering dry farming techniques is the first choice to increase the output of local rice and maintain the ecological environment.
