为科学合理施肥及集约经营管理黄竹林提供参考,对赣县大田乡不同配方施肥黄竹林的叶片养分含量与土壤肥力及产量的相关性进行研究.结果表明:施肥可明显提高竹林土壤的供肥能力,快速补充竹叶养分,增加竹林产量,而不同配方肥中又以矿渣肥2效果最好.影响竹叶N素含量的主要肥力因子及其影响顺序为:全N>速效N>有机质>全P.影响竹叶P素含量的肥力因子及其影响顺序为:速效K>全N>速效P>全K.影响竹叶中K含量的肥力因子及其影响顺序为:全N>全P>全K>速效N.黄竹竹叶N元素含量与产量呈显著正相关,黄竹竹叶中N元素含量的临界值为20.46 g/kg,最适值为22.94 g/kg,可用于黄竹营养诊断.
A Study on Correlation between Leaf Nutrition and Soil Fertility and Output of Bambusa rigida
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.
