植物生长调节剂“爱密挺”对花生生长及产量的影响

Effects of Natural Plant Growth Regulator Emistim C on Peanut Development and Yield

大田条件下,以花生品种花选14号为试材,研究了纯天然植物生长调节剂"爱密挺"对花生生长及产量的影响。结果表明,(1)各处理对花生个体和群体生长均有不同程度的影响,T4处理"爱密挺拌种+爱密挺开花期喷雾"的株高、单株叶面积和群体生长率最大,其次是T2处理"爱密挺拌种,"T3处理"爱密挺开花期喷雾"效果最差,但三指标也均高于对照T1。(2)各处理单株总荚数、单株果仁重和单株荚果重均较对照有所提高,百仁重降低,千克果数增加,即平均单果重降低;产量由高到低的顺序为T4>T2>T3>T1,且T4处理的产量与对照的差异达到了显著水平。表明纯天然植物生长调节剂"爱密挺"在花生上有推广应用的价值。

Field trial was carried out to discover the effects of natural plant growth regulator Emistim C on peanut development and yield with the variety of ＂Huaxuan 14＂.The results showed：（1） The effects of all the treatments on peanut growth of individuals and groups were different in varying degrees.The values of height,leaf area and crop growth rate of treatment4 which was ＂seed dressing with Emistim C＋spray in flowering stage with Emistim C＂ were all the highest.Next were treatment 2 which was ＂seed dressing with Emistim C＂.The effect of treatment 3 which was ＂spray in flowering stage with Emistim C＂ was the lowest,but its values of height,leaf area and crop growth rate were all higher than those of treatment 1 which was CK.（2） The total number of pods,seeds weight and pods weight per plant of every treatment were all increased,100-seeds weight were decreased and the number of pods per kilogram were increased that is the average pod weight were decreased.The decreasing order of yield is T4T2T3T1.There was obvious difference between treatment 4 and treatment 1（CK） on yield.These indicated that natural plant growth regulator Emistim C has the value to be spreaded and applied on peanut.
