摘  要:
采用稻草还田免耕直播、稻草还田翻耕直播、非稻草还田免耕直播和非稻草还田翻耕直播4种耕作方式,探讨其对水稻经济性状的影响。结果表明,水稻免耕直播比翻耕直播能极显著提高结实率,显著增加穗粒数和着粒密度,从而显著提高水稻产量。稻草还田比非稻草还田也能显著提高水稻的结实率。但两者对水稻有效穗、株高、穗长、千粒重等性状没有影响。

摘  要:
Four different plowing methods,straw returning to field and plowing-free and direct sowing,straw returning to field and normal plowing and direct sowing,non straw returning to field and plowing-free and direct sowing,non straw returning to field and normal plowing and direct sowing,were used in this paper to explore their effect on economic properties.The result indicated that the treat with straw returning to field and plowing-free and direct sowing was the best of four treats,for its devote to rice yield by increasing the seed rate and seed number.It was not very effective on the ear number of rice,plant height,ear length,weight of 1000 grain and so on.
