摘　　要：磷酸二氢钾对花椒抗寒性有显著影响,其中喷施3次抗寒效果最好,新梢受冻率比对照降低了20.18%,枝条受冻率比对照降低了10.51%;磷酸二氢钾对花椒坐果率和单株产量也有明显影响,其中喷施3次坐果率和单株产量最高,比对照提高了18.44%和1.9 kg。Effect of potassium dihydrogen phosphate on cold hardiness and yield of Zanthoxylum bungeanum were studyed. The results showed that the potassium dihydrogen phosphate have significant effect on cold cold resistance of Zanthoxylum bungeanum, the effect of Sprayed three were the best, young shoots freezing rate reduced 20. 18% than control, branchs freezing rate reduced 10. 51% than control; Potassium dihydrogen phosphate have significant effect on fruit setting rate and yield of Zanthoxylum bungeanum, sprayed three time fruit setting rate and yield per plant of were the highest, improved the 18. 44% andl. 9 kg than control.
