摘　　要：为促进黑龙江省小豆产业提质增效,以龙红豆4号和冀红352为试验材料,分别于2022和2023年进行硫酸锌施用浓度和施用次数效果试验。2022年,设置5个ZnSO4浓度(质量百分数为0%,0.1%,0.2%,0.3%和0.4%),在结荚期进行叶面喷施处理,研究其对小豆产量因子及籽粒锌含量的影响,并筛选出最佳施用浓度(0.3%)。2023年,在结荚初期、结荚中期、结荚初期+结荚中期,进行叶面喷施0.3%的ZnSO4筛选出最佳喷施次数。2年研究结果表明,喷施外源ZnSO4可提高小豆单株有效荚数、单株粒重和百粒重。喷施0.3%的硫酸锌最为适宜,能有效提高小豆百粒重和籽粒锌含量,分别较CK提高6.68%~9.97%和16.17%~25.33%;在结荚初期+结荚中期叶面喷施2次浓度为0.3%的外源ZnSO4可显著提高小豆籽粒锌含量,龙红豆4号和冀红352较对照分别提高33.33%和48.16%,喷施2次与喷施1次相比,显著提高了冀红352的单株产量。In order to promote the improvement of quality and efficiency in the adzuki bean industry in Heilongjiang Province,experiments were conducted on the effects of zinc sulfate application concentration and application frequency using Longhongdou 4 and Jihong 352 as experimental materials in 2022 and 2023,respectively.In 2022,five concentrations of ZnSO 4(mass percentages of 0%,0.1%,0.2%,0.3%,and 0.4%)were set up for foliar spraying during the podding stage to study their effects on the yield factors of adzuki beans and the zinc content in seeds.The optimal application concentration(0.3%)was selected.In 2023,foliar spraying of 0.3%ZnSO4 was conducted during the early,middle,and early+middle stages of podding to select the optimal spraying frequency.The results of the 2-year experiment showed that spraying exogenous ZnSO 4 can increase the effective pods per plant,grain weight per plant,and hundred grain weight of adzuki beans.Spraying 0.3%ZnSO 4 was the most suitable,which could effectively increase the 100 grain weight and zinc content of adzuki beans,increasing by 6.68%-9.97%and 16.17%-25.33%respectively compared to CK;Spraying exogenous ZnSO 4 with a concentration of 0.3%twice during the early and middle stages of podding could significantly increase the zinc content in adzuki bean seeds.Longhongdou 4 and Jidou 352 increased the zinc content by 33.33%and 48.16%,respectively.Compared with spraying once,spraying twice significantly increased the yield per plant of Jihong 352.
