丛型整枝技术对寒地茄子产量的影响

Effects of ‘Tuft-type’ Mode on Eggplant Yield in Cold Regions

为指导黑龙江省早春露地茄子生产获得高产,以“龙杂茄9号”紫长茄为试材,采用丛型整枝方式,以常规整枝方式为对照,研究了丛型整枝技术与植株营养生长、产量的关系。结果表明:丛型整枝的植株根系鲜质量比对照增加66.12%、干质量增加56.04%,侧根系明显发达于对照;丛型整枝的门茄结果数比对照增加111.78%、对茄增加148.75%、四面斗增加42.75%。丛型整枝由于结果数多,产量显著地增高,前期产量比对照提高48.96%,总产量提高27.09%。

To guide the early spring eggplant production in Heilongjiang Province,taking ‘Long za eggplant 9’ as test material,adopted to the ‘Tuft-type’ compared to the routine pruning and researched the relationship between the ‘Tuft-type’ and the plant vegetative growth and the yield.The results showed that compared to CK,the fresh weight and dry weight of ‘Tuft-type’ eggplant root has increased by 66.12% and 56.04%,and the sub-root was obviously more developed;‘Tuft-type’ mode was better than the traditional one on the yield,the first fruit number,the second fruit number and the third fruit number of ‘Tuft-type’ mode has enhanced by 111.78%,148.75% and 42.75% than CK respectively.Because of the more fruit number by ‘Tuft-type’,the yield has increased significantly,the pre-production has enhanced by 48.96% than CK and the total production has enhanced by 27.09%.
