摘要
采用正交试验设计法研究了种植密度、复合肥、N肥、透光率对1年生高地省藤苗木生长的影响。结果显示,4种因素对苗木生长均有极显著影响,其中种植密度是最关键因素,其次为复合肥,影响因素最小的为透光率;筛选出的最佳处理组合为植株密度15 cm×15 cm、透光率50%、不施N肥和复合肥时藤苗生长效果最佳。
This paper adopted orthogonal experiment to study the effect of planting density, rate of light transmittance, compound fertilizer and nitrogenous fertilizer on the growth of 1-year-old seedlings of Calamus nambariensis vat. alpgnu. The results showed that all of 4 impact factors had extremely significant impact on the seedling growth, of which planting density was the most critical impact factor, followed by compound fertilizer, while rate of light transmittance was the minimum one. The seedlings of C nambariensis var. alpinu grew best under the optimum treatment combination of planting density with 15 cm×15 cm and 50% rate of light transmittance without compound fertilizer and nitrogenous fertilizer
