氮磷钾不同配比对丽江云杉幼苗生理生长的影响OA北大核心CSTPCD
Effects of Fertilization with Different Proportion of Nitrogen,Phosphorus and Potassium on Physiology Growth of Picea likiangensis Seedlings
以3年生优质丽江云杉苗木为研究对象,通过盆栽试验,采用3因素3水平正交设计,对苗木进行氮磷钾不同配比的9种施肥处理,分析其对丽江云杉苗木生长和光合特性的影响.结果表明:不同氮磷钾配比对丽江云杉幼苗的苗高、冠幅、叶绿素含量和光合特性均有一定促进作用,但不同处理组间有所差异.T7施肥配比(尿素5 g/株、过磷酸钙7 g/株、硫酸钾2.5 g/株)对丽江云杉冠幅、叶绿素含量、净光合速率、气孔导度、蒸腾速率和光补偿点的促进效果最明显,显著高于对照.综合来…查看全部>>
Taking the three-year high-quality seedlings of Picea likiangensis as the research object,the ortho-gonal design of 3 factors and 3 levels was used to treat seedlings with 9 different fertilization treatments with dif-ferent ratios of nitrogen,phosphorus and potassium through pot experiments to analyze the effects on the growth and photosynthetic physiology of P.likiangensis seedlings.The results showed that different proportion of nitro-gen,phosphorus and p…查看全部>>
