钻天柳优树选择与播种育苗技术研究

以优树种子为材料,进行播种育苗试验的结果表明:秋播效果优于春播,收集种子后混沙撒播效果最好,出苗率90%以上。以5株优势木对比法为依据,确定了钻天柳优树选择标准为:胸径、树高及单株材积分别大于5株优势木平均值的1.1、1.12及1.29倍。

The Research on the Superior Tree Selection and Seed Breeding Technology of Chosenia arbutifolia

In this paper, we determined the superior tree selection criteria of Chosenia arbutifolia were diameter at breast height, tree height and tree volume were greater than 5 dominant trees average value of 1.1 times, 1.12 times and 1.29 times with the 5 strains of dominant comparative method as the basis. Using the superior tree seeds as material, the seedling test results showed that： the autumn sowing effect was better than that of spring sowing, mixed the seeds with sand before sowing could get the best effect, the seedling emergence rate was more than 90%, to enhance water management was the key to the success of its seedlings in the rooting period.
