摘要
为确定黑果枸杞栽植的株行距,以黑果枸杞为试验材料,采用实生苗进行田间栽植,分别设置3 个不同株距1、1.2、1.5 m,以及3 个栽植株行距1.5 m×2 m、1.5 m×3 m和2 m×2.5 m,通过测定株高、冠幅、分枝数、侧枝数、侧枝长、尖削度、坐果率、果实参数、产量等,比较不同株距和栽植株行距对黑果枸杞生长发育及果实表型性状的影响.结果表明,黑果枸杞人工栽培的合适株距为 1.5 m,行距2～3 m,在保持单株占地面积相近的情况下,可根据需要适当地调整株行距;栽植株行距为1.5m×3 m时,果型变异小,果实纵径、横径、果型指数等表型特征较稳定.以期为人工栽培管理提供技术参考.
Abstract
To determine the plant-row spacing of Lycium ruthenicum,the seedlings were used for field planting,with three different plant spacing of 1,1.2,1.5 m,and three plant-row spacing of 1.5 m×2 m,1.5 m×3 m and 2 m×2.5 m,the effects of different plant-row spacing on the growth and phenotypic traits of Lycium ruthenicum were compared by measuring plant height,crown width,number of branches,num-ber of lateral branches,length of lateral branches,tree tapering,fruit setting rate,fruit parameters and yield.The results showed that the proper plant spacing and row spacing for artificial cultivation of Lycium ruthenicum were 1.5 m and 2-3 m respectively,and the plant-row spacing could be adjusted appropriate-ly as required while in similar occupy area for individual plant;under the planting space of 1.5 m×3 m,the fruit variation of Lycium ruthenicum was small,fruit phenotypic characteristics such as longitudinal di-ameter,transverse diameter and fruit shape index were stable relatively.The results aim to provide tech-nical references for artificial cultivation management.
