钙肥对板栗幼苗三大基本营养元素吸收的影响
Effects of Calcium on Absorption of Three Basic Nutrients about Chestnut Seedlings
摘要
Abstract
[ Objective] To study the effect of calcium fertilizer on the absorption of N, P, K about chest seedlings. [ Method ] Different concent rations of calcium fertilizer were sprayed to one-year and two-year seedlings, then the N, P, K content of different part of chest seedlings were determined. [ Result ] The results of the experiment showed that when the calcium concentration was3 mmol/L, the calcium content was the highest to all the seedling except for the one year seedlings, root which happened to be the concentration of 2 mmol/L. The maximum concentration of N correspond to the most appropriate calciumfertilizer were 4, 5, 3 mmol/L respectively. The leaf, stem and root of one-year seedlings. The maximum concentration of N correspond to the most appropriate calciumfertilizer was 3 mmol/L of all organs of two-year seedlings. The maximum concentrations of P and K flux largely to the organs of all seedlings, they happened to be 3, 4, 5 mmol/L. [ Conclusion] The calcium can improve the content of N, P and K of chestnut seedlings to some extent, and the nutritional quality of Chinese chestnut as well.关键词
