花生在开花下针期吸收的养分占一生总吸肥量的 60％～ 70％，因此在开花下针期施肥利用率高，增产效果显著。据试验，在花生开花下针期每亩施氯化钾 10 kg或施 25％复混肥料 20 kg，单株总荚果数比不施肥处理增加 7.19荚和 8.34荚，且幼果、秕果数少，饱果数多，每亩产量增加 8 Peanut in the flowering needle absorption of nutrients accounted for 60% to 70% of the total fat absorption, so flowering needle acupuncture fertilization and utilization rate is high, the yield is remarkable. According to the experiment, under the flowering of peanut needle per acre KCl 10 kg or 25% compound fertilizer 20 kg, the number of pods per plant than the non-fertilization treatment increased 7.19 pods and 8.34 pods, and young fruit, fruit number Fewer, full fruit, yield per acre 8
