在柴达木盆地研究了枸杞不同栽植方式对其幼苗及土壤盐碱性的影响。结果表明，地下30 cm处铺地膜及稻草、地下30 cm处铺地膜、地下30 cm处铺稻草、沟壑栽植及起垄栽植均可增加枸杞叶片面积，但对土壤pH影响不大。其中沟壑栽植及起垄栽植的土壤电导率较低，使盐分对植株的影响大大减小，能够提高枸杞幼苗的成活率及叶片吸收水分的能力。综合考虑，沟壑和起垄栽植是盐碱地枸杞栽植的适宜方式。

The effects of different planting methods of Lycium barbarum on its seedling and soil salinity were studied in Qaidam Basin. The results showed that it is all increased leaf area of Lycium barbarum which mulching with plastic film and straw at 30 cm underground， mulching with plastic film at 30 cm underground， mulching with straw at 30 cm underground， planting in furrows and planting on ridges， but had little effect on soil pH. Among them， the soil electrical conductivity of planting in furrows and planting on ridges was low， which greatly reduces the effect of salt on the plant， and can improve the survival rate of Lycium barbarum seedlings and the ability of leaf to absorb water. In conclusion， planting in furrows and ridges are the suitable planting methods of Lycium barbarum in saline-alkali land.
