野生黑果枸杞硬枝扦插育苗影响因素试验

Factors Affecting Seedlings of Wild Bback Wolfberry by Hardwood Cuttage

本文进行了野生黑果枸杞春季硬枝扦插育苗试验。试验结果显示,青海、山东、甘肃兰州三个种源地引进的野生黑果枸杞成活率存在差异,从青海引进的野生黑果枸杞硬枝扦插苗成活率最高,平均成活率达92%;从山东引进的成活率最低,平均成活率为86%。黑地膜覆盖与否对野生黑果枸杞硬枝扦插生长成活有一定影响,覆盖黑地膜的苗木平均苗高、平均地径明显优于不覆盖黑地膜的苗木,黑地膜覆盖与生长量、成活率呈正相关。在杂草较多的地方,采用黑膜可以抑制杂草生长,减轻除草工作量。白地膜覆盖杂草较多,需要人工除草。

In this paper, experiment on hardwood cutting and seedling raising of wild black wolfberry in springwere carried out. The results showed that there were differences in survival rate of wild wolfberry fruitintroduced from three sources of Qinghai province, Shandong province, and Lanzhou city. The survival rate ofhardwood cutting of wild wolfberry introduced from Qinghai province was the highest, with an average survivalrate of 92%. That of Shandong province was the lowest（86%）. The coverage of black mulch had a certain effecton the growth of hard branch of wild black fruit and wolfberry. The average seedling height and averagediameter of the seedlings covered with black film were obviously better than that of the seedlings that do notcover the black film. The cover of black film was positively related to the growth and survival rate. In areaswhere weeds are abundant, black mulching film can inhibit weed growth and reduce herbicidal workload. Thereare more weeds in white ground film, and artificial weeding is needed.
