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 ,丰之露和植壮素处理均增加了灌浆持续期天数
Eight kinds of biochemicals were applied to foliar spray at heading stage to explore their effects on yield increasing and the difference between high yield and chlorophyll production. Using Logistic equation, Efficient green abundance treatment for comparative analysis. The results showed that: (1) The yield of the other six compounds increased significantly with the exception of potassium phosphate and potassium hydroxide, and the yield of uniconazole was up to 11.84%, followed by that of high efficiency chlorophyll, Full, force abundance, phytosome. (2) All kinds of biochemical agents increased grain weight by one thousand kernels except for phosphorus, potassium and potassium, and the other six treatments increased the seed setting rate. (3) Spraying chlorophyllin increased the grain filling intensity and reduced the number of days of grouting, Fenglu and chlorophyll increased the duration of grouting
