摘  要：
【目的】通过对幼龄灰枣适宜负载量的研究,以期为实现枣高产、优质和高效栽培提供基础。【方法】以34、龄灰枣嫁接苗为试材,通过连续2年的研究,探讨负载量与枝组粗度、产量及单果重的关系。【结果】枝组粗度(X)与产量(Y)成显著相关性,其回归方程为Y=219.6X-102.7,枝组负载量(Y)与枝组粗度(X1)和平均单果重(X2)的回归方程为Y=[219.6X1-102.7]/X2;单株负载量与产量成正相关,与单果重及枣果均匀度成反相关;枣吊1~7节保果数约占总保果数的89.7%;枣吊负载量越大,落果率越高、单果重越小。【结论】3龄灰枣单株负载量以150个果左右为宜;生产中枣吊摘心宜在第8个节点后;单个枣吊负载量以保留2个枣果为宜。

摘  要：
【Objective】Study on suitable furit load of young Ziziphus jujuba cv.Huizao,expecting to provide planting technology of high yield,fine quality and efficiency.【Method】3-4 years of Huizao were used as study material.The relation between fruit load and branch group diameter,yield and single fruit weight were studied for two years in succession.【Result】The branch group diameter(X) was positively correlated with yield(Y) and the regression equation was Y=219.6X-102.7,the regression equation of group load with branch group diameter and average single furuit weight(X2) was Y=[219.6X1-102.7]/X2;the single plant load was positively correlated with yield,and negatively correlated with fruit single weight and fruit evenness;The fruiting percent of 1-7 bearing branch was 89.7% within fruit number.The higher the bearing branch ,the higher the fruit drop rate and the smaller the single fruit weight.【Conclusion】The suitable fruit load of three ages Huizao tree was 150;The suitable bearing branch should be pruned after the eight node;The suitable single bearing branch fruit load was 2 fruit per branch.
