摘　　要：通过大田对比试验研究了果实膨大期不同叶面喷水量、喷水时期对大红袍花椒产量和品质的影响。结果表明:果实膨大期叶面喷水能明显提高花椒产量和品质,0.5h、1h和1.5h等不同喷水量的单株产量分别为5.4、9.5和7.3kg,分别比对照增长了12.50%、97.92%、52.08%,其中喷水量1h的增幅最大;早上、中午、下午和晚上等不同喷水时期叶面喷水对花椒单株产量、皮籽比、果径和果色的影响存在显著性差异,单株产量分别为7.2、9.5、6.8和6.3kg,其中中午喷水的单株产量最大。Through field comparison tests,the effects of different amount of foliar spray,spraying period on yield & quality of Zanthoxylum bungeanum at the swollen stage were studied.Result shows that:foliar spray can significantly improve the yield &quality of Zanthoxylum bungeanum at the swollen stage;yield per plant with different spraying amount(0.5h,1h&1.5h)are 5.4kg,9.5kg &7.3kg respectively,which increase by 12.50%,97. 92% &52.08%than that of the CK,among which spraying amount in 1his the largest amount;effects of foliar spray on yield per plant,pericarp seed ratio,fruit diameter,fruit colour are significantly different in the morning, noon,afternoon &evening.Yield per plant are 7.2,9.5,6.8 &6.3kg,among of which spraying at noon obtain the maximum yield per plant.
