花棒植苗造林成活率低,影响造林速度。为此,我们进行了花棒扦插造林试验。试验地设在榆林县牛家梁林场沙地上。选择当地花棒枝条截干作插穗,用1年生实生苗作对比。造林试验共分6组33个小区,对比排列,每小区面积为0.3公顷,栽植300株(穴)。扦插造林每穴4根插条,植苗造林每坑栽植1株。扦插造林采取随砍、随剪条,随栽植,栽时留头3厘米。栽后随即搭设死物(柴草)障蔽,并于当年和次年9月,采用机械抽样,分别进行成活率、保存率、生长量等项目的调查,每小区抽样面积为20%。
Hualong seedling planting afforestation survival rate is low, affecting afforestation speed. To this end, we conducted a stick test afforestation. Experimental site is located in Yulin County, cattle home beam forest farm on the sand. Select the local spent sticks cuttings for cuttings, with 1-year-old seedlings for comparison. Afforestation experiment is divided into 6 groups of 33 plots, contrast arrangement, each plot area of 0.3 hectares, planted 300 (points). Cuttings per hole 4 cuttings, planting seedlings planting a hole per pit. Cuttings taken with the cut, with the cuttings, with planting, planted head 3 cm. In the same year and the following September, mechanical sampling was used to investigate the survival rate, preservation rate and growth rate respectively. The sampling area was 20% for each plot.
