生命素在棉茬小麦上的喷施效果

The Spraying Effect of Plant Growth Regulator on Wheat Growing under Cotton Stubble

以小麦品种淮麦30为试材,分别在棉茬小麦的孕穗期和灌浆期喷施不同浓度的永业生命素叶面肥,以喷施清水处理为对照(CK),分析了在小麦不同生育时期喷施不同浓度永业生命素的产量效果及其增产机理。结果表明:在小麦生育后期喷施生命素,能够优化小麦的产量性状,改善小麦穗部性状,减少基部小穗退化,达到增粒、增重、增产的目的。其中,在小麦孕穗期和灌浆期各喷施1次1500 mL/hm2的生命素效果最好,增产率为6.01%。

Using wheat variety huaimai 30 as test material, at booting stage and filling stage of wheat growing under cotton stubble spraying different concentration of Yongye plant growth regulator leaf fertilizer, by spraying water treatment as control, the yield effect and the mechanism of spraying different concentration of Yongye plant growth regulator at different stages of wheat were analyzed. The results showed that spraying plant growth regulator in the later growth period of wheat could optimize the yield traits, improve the panicle characters, reduce the basal spikelet degeneration and achieve the purpose of increasing grain, weight and yield of wheat. The yield increasing effect of spraying one time of 1 500 mL/hm2 of plant growth regulator respectively at booting stage and filling stage of wheat was better, and the rate of yield increasing was 6. 01%.
