杂交油菜品种黔油30号不同免耕栽培密度的丰产性

摘要

为了探明杂交油菜品种黔油30号在贵州轻简化栽培的适宜密度及其丰产性,分别在遵义县、贵阳市、金沙县和平坝县对该品种进行多点免耕栽培密度试验.结果表明:黔油30号免耕栽培的适宜密度为1.8万～2.4万株/667m2,产量为145 kg/667m2左右,且在遵义、金沙、贵阳和平坝等地生产上应用该密度对黔油30号进行免耕栽培均具有较大增产潜力.%No-tillage density tests were conducted in Zunyi County, Guiyang City, Jinsha County and Pingba County to explore the suitable density and yielding ability of hybrid rape cultivar Qianyou 30 under simplified cultivation. The results showed that the optimum no-tillage cultivation density of Qianyou 30 was 18?4 thousand plants per 667 m2 with the yield of about 145 kg/667 m2. This no-tillage cultivation density was of great yield-increasing potential in Zunyi County, Guiyang City, Jinsha County and Pingba County.
