摘  要:
以优质香型杂交水稻宜香1577为材料,在四川南部主要针对密度对该品种的强化栽培技术进行了研究。本研究设置了14.1、9.0和4.0万株/hm23种密度,结果3种密度下叶龄变化进度一致;密度为4.0万株/hm2的单株分蘖较前两种密度的多,最高苗时已达极显著水平;3种密度下每10 d增蘖数变化进度一致;密度为9.0万株/hm2的产量最高,较密度4.0万株/hm2的产量达极显著增产。可见在四川南部宜香1577适宜按9.0万株/hm2的密度进行强化栽培。

摘  要:
Using the material of hybrid rice Yixiang 1577,the culturing density in the south of Sichuan province under SRI was studied.The experiment arranged three kind of culturing densities,14.1×104,9.0×104 and 4.0×104 hole/hm2.The result indicated that three culturing densities'leaf developing paces were much the same.The tillering number of the density 4.0×104 hole/hm2 was the most among three culturing densities and reached extremely significant level.The adding tillering's change per 10 d was the same.The yield of the density 9.0×104 hole/hm2 was the highest and reached extremely significant level.So the suitable culturing density of Yixiang 1577 in the south of Sichuan province was 9.0×104 hole/hm2.
