摘要
水杉芽苗移栽后遮阳网覆盖与芦帘覆盖相比较,光照强度可增加30～40％,早春可提高温度2～3℃,防暴雨冲刷作用十分明显,土壤疏松,有利于苗木生长,成苗率提高11.5％,每亩可增产苗0.77万株,苗高增加42.5％,地径增粗17.0％,Ⅰ、Ⅱ级苗增加11.1％,增加收入616元,节约成本206元,节省人工65个。
After bud-seedling transplanted, ysed shading net for covering material, the illumination strength, the temperature inside in eary spring, the servival rate of seedling, the output of seedling, the height growth, the diameter of earth stem, the ratio of the first and second grade seedling, and the income could be increased 30% to 40%,2-3℃, 11.5%, 7.7 southan-ds plants /mu, 42.5%, 17.0%, 11.1% and 616 yuans, respectively, but 206 yuans of cost and 65 work days can be saved, compared with using the covering material.
