“易丰收”植物生长调节剂在花生上的应用效果研究

Study on the Application Effect of "easy to harvest" Plant Growth Regulators in Peanut(Arachis hypogaea L.)

[目的]研究"易丰收"植物生长调节剂在花生上的应用效果。[方法]采用小区、大区对比与小面积示范试验研究"易丰收"拌种、幼苗期叶面喷施和开花下针期喷施处理对不同茬口地种植花生的主要形态性状、经济性状及产量的影响。[结果]经"易丰收"3种不同方式处理的花生的主要形态性状、经济性状、产量均优于对照;大区对比与小面积示范试验结果表明,3种处理均比对照增产4.9%～7.8%,且"易丰收"应用越早增产效果越好,拌种比幼苗期喷施增产效果好,幼苗期喷施效果又好于开花下针期效果;在生茬地应用的增产效果要好于重茬地。[结论]"易丰收"植物生长调节剂能显著提高花生的形态性状、经济性状,对花生有显著的增产效果,可进一步在生产上推广应用。

[Objective]To study the application effect of ＂easy to harvest＂ plant growth regulators in peanut.[Method]The effect of ＂easy to harvest＂ which were applied in the ways of seed dressing,foliar-spraying at young seedling stage,spraying at flowering stage on morphological characters,economic characteristics and yield of peanut were studied.[Result] The effect of three kinds of treatments with ＂easy to harvest＂ on morphological characters,economic characteristics and yield of peanut were all better than that of CK.The results of large plots and plant experimentally in small areas tests showed that the yields of three kinds of treatments were increased by 4.9%~7.8%.The earlier of ＂easy to harvest＂ applied,the yield increasing effect better.Seed dressing treatment got the best yield increasing effect,foliar-spraying at young seedling stage treatment second,the spraying at flowering stage treatment third.Yield increasing effect in the rotation cropping was better than that in the continuous cropping.[Conclusion] Plant growth regulators ＂easy to harvest＂ could improve the morphological characters,economic characteristics and yield of peanut significantly;it could be applied and spread in the production of peanut.
