以长白山笃斯越桔当年播种实生苗为试材,采用‘3414’试验设计,选取氮、磷、钾为试验的3个因素,对笃斯越桔苗木施肥措施进行了探究。结果表明:笃斯越桔苗期施肥措施为施纯N 83~90kg·hm~(-2),纯P2O514~21kg·hm~(-2),纯K2O 3~6kg·hm~(-2),苗木株高≥12cm;且氮的贡献率最大,磷的贡献率略低于氮,钾的贡献率最小。
Taking the seedlings of Vaccinium argenteas Blanchard in Changbai Mountain as test materials, the fertilization measures of Vaccinium crenata nursery stock were studied using the “3414” experimental design, selecting three factors of nitrogen, phosphorus and potassium. The results showed that the fertilization measures of seedling stage of Vaccinium argenteus were as follows: N 83 ~ 90kg · hm -2, pure P 2 O 14 ~ 21kg · hm -2, pure K 2 O 3 ~ 6kg · hm -2, , Seedling height ≥12cm; and the contribution rate of nitrogen is the largest, the contribution rate of phosphorus is slightly lower than that of nitrogen, and the contribution rate of potassium is the smallest.
