| 摘 要： | 2006年在贵阳郊区(海拔1140 m)用杂交稻新品种黔优301进行了一组不同施肥量和栽插株数的栽培试验,在蚕豆绿肥田不施用农家肥,只施用尿素,机耕,4月初播种和密度1.2万窝/667m2的条件下,栽插株数间差异不显著,施肥量间差异极显著,最佳栽培处理为栽插1株,施尿素3次,共15 kg/667m2,产量为670.0 kg/667m2。并讨论了该品种的高产栽培技术措施。

| Abstract: | Qianyou 301,a new hybrid rice variety,was tested to investigate effects of different urea amount and seedling number/hole on its yield.The results indicate that there is no significant difference in different seedling number/hole and a significant difference in different urea application amount under the cultivation condition in the first ten-day period of April of sowing time,12,000 holes/667m2 of plant density and only applying urea fertilizer.The yield of 670 kg/667m2 can be gained under 1 seedling/hole and 15 kg/667m2 of urea amount with 3 applications.The cultivation technique for high yield of Qianyou 301 is discussed at the same time. |
