采用正交设计试验,研究施肥、解淀粉芽孢杆菌对高地省藤(Calamus nambariensis Becc.var.alpinus S.J.Pei et)苗期生长的影响。结果表明:(1)解淀粉芽孢杆菌(Y2菌株)和施肥(尿素、过磷酸钙、复合肥)对高地省藤苗生长具有显著影响;(2)综合各因素水平对高地省藤苗地径和苗高生长指标的影响以及节省生产成本的原则,确定的最佳组合为A4B1C2D1,即8×10~6 CFU/MLY2菌株,不施尿素(0g)、施用过磷酸钙20g,不施复合肥(0g)时,高地省藤苗生长最好。
Orthogonal design experiments were conducted to study the effects of fertilization and Bacillus amyloliquefaciens on the seedling growth of Calamus nambariensis Becc. Var. Alpinus S.J. Pei et. The results showed that: (1) Bacillus amyloliquefaciens (strain Y2) and fertilization (urea, superphosphate and compound fertilizer) had significant effects on the growth of vine seedlings in the highland; (2) The results showed that the best combination was A4B1C2D1, which was 8 × 10 ~ 6 CFU / MLY2 strain, no urea (0g), 20g of superphosphate and no compound fertilizer (0g), the highland province seedling grow best.
