摘　　要：对实施5年林草复合经营技术的金丝王枣果园果实产量及品质进行了调查,结果表明:不同样地中在相同株行距的同组内部和不同株行距的组之间果实产量和品质呈现差异,在株行距相同的情况下,果园生草可显著提高产量;株行距4 m×1.5 m时果实品质最好;株行距以4 m×2 m为综合评价最优;在管理水平相当的果园中,在平均单株产量近似的情况下,裂果质量比和裂果率比呈现出较为明显的差异,分别较对照降低60%左右。The experiment was conducted to investigate the fruit yield&quality of Zizyphus jujube Mill.‘Jinsiwang’orchard,which had been used for five years.The study found that differences in fruit yield&quality in the same group with the same plant row-spacing and between groups with different plant row-spacing in different sample plots.In the case of the same plant row-spacing,planting grass can significantly increase the yield,the fruit quality is the optimal when plant row-spacing is 4 m×1.5 m,the optimal comprehensive evaluation when plant row-spacing is 4 m×2 m.There are significant differences on the split fruit weight ratio&fruit cracking ratio when the average yield per plant is similar in comparable management level orchards,it is about 60%lower than CK.
