A Study on Correlation between Leaf Nutrition and Soil Fertility and Output of Bambusa rigida
摘要
Abstract
In order to provide reference for scientific and rational fertilization and management of Bambusa rigida forest, the correlation of leaf nutrition to soil fertility and output of B. Rigida in Datianxiang of Kan -Hsien was studied through prescription fertilization. The results showed that fertilizer could improve the fertilizer - supplying capacity of bamboo soil and promote supplement of nutrition to leaf and add bamboo production. The slag fertilizer 2 had the best effect in the different formulations of fertilizers. The major factors influencing nitrogen content in Bambusa rigida leaf were in the order: total N > available N > organic matter > total P in soil. The major factors influencing phosphorus content in Bambusa rigida leaf were in the order available K >total N > available P > total K in soil. The major factors influencing potassium content in Bambusa rigida leaf were in the order;total N > total P > total K > avaiable N in soil. The N element content in bamboo leaf and the production were significantly positively correlatied. Critical value of N content in Bambusa rigida leaf was 20.46 g/ kg, the optimum value was 22.94 g/kg, the critical value of N content in Bambusa rigida leaf can be applied in nutrient diagnosis.关键词
