| 摘 要： | 对水稻进行育秧床温调控剂及分蘖促进剂应用试验研究,结果表明:床温调控剂处理的水稻秧苗素质显著改善,株高降低14.9%、地下百株干重提高29.59%、根冠比增加31.74%。移栽本田后,穗数增加34.7穗/m2,增产率达到5.7%;分蘖促进剂的应用明显加快了水稻分蘖前期的分蘖速度,收获穗数增加19.9穗/m2,增产率达到6.6%。两者配合应用增产效果更好,水稻的收获穗数增加54.6穗,增产率达到12.7%。

| Abstract: | The regulatory medicament of seedbed and tillering promoters were researched and the results indicated that regulatory medicament of seedbed can improve seedling quality,lessen the plant height by 14.9%,increase the 100-plant dry weight by 29.59%,enhance the root/shoot ratio by 31.74%.after transplanting it can increase the panicles by 34.7 per square meter and the yield increasing rate was 5.7%.the tillering promoters can improve rate of tiller obviously in early stage,increase the effective panicles per unit area by 19.9,the yield increasing rate was 6.6%.the better effect can be achieved when used together,which the effective panicles per unit area can increase 54.6 and yield increase rate was 12.7%. |
