不同生化剂对水稻产量及灌浆特性的影响

Effect of Different Biochemistry Material on Rice Yield and Study on the Filling Character

取 8种生化剂 ,在水稻抽穗期进行叶面喷施 ,探讨它们的增产效果及与高效绿丰素增产作用的差异 ;利用Logistic方程 ,对丰之露和植壮素 2处理的灌浆特性与高效绿丰素处理进行比较分析。结果表明 :( 1)除磷钾精和云大 12 0外 ,其余 6种都有增产作用 ,烯效唑的增产效果最好达 11.84%,其次为高效绿丰素、丰之露、粒粒饱、力丰、植壮素。 ( 2 )各种生化剂处理都提高了千粒重 ,除磷钾精和云大 12 0处理外 ,其余 6处理均提高了结实率。 ( 3 )喷绿丰素处理提高了籽粒灌浆强度 ,减少了灌浆持续期天数 。

Eight kinds of biochemistry materials spraying the leaf at the heading stage were experimented to explore their effects of increasing yield. The filling characters of two treatments of spraying Fengzhilu and Zhizhuangsu were also analyzed, compared with efficient Lufengsu. The results showed that six treatments had the efficiency of increasing yield except two treatments of spraying Linjiajing and Yunda 120. The rate of increasing yield by spraying Xixiaozuo, Fengzhilu, Lilibao, Lifeng and Zhizhuangsu was respectively 11.84%, 7.50%, 6.58%, 6.04% and 2.63% . The treatment of spraying Lufengsu enhanced the grain filling rate,shortened the filling duration, but the treatments of spraying Fengzhilu and Zhizhuangsu could add the filling duration. All treatments may enhanced the 1 000 grains weight.Other six treatments could increase the filled grain rate except two treatments of spraying Linjiajing and Yunda 120.
