应用土壤养分状况系统研究法(ASI),以高梁作指示植物,对江西赣县黄竹林土壤养分进行了测定与分析,以评价养分状况及主要限制因子。结果表明:黄竹林土壤贫瘠,有机质含量较低,N、P、K、S、Mg元素严重缺乏,而Zn的含量稍低,Ca、B、Cu、Fe、Mn的含量丰富;土壤对P、K、S的吸附固定量大,对Zn、Cu的吸附固定量较小,而对B、Mn几乎无吸附固定作用。盆栽试验结果表明,P是黄竹林土壤养分的第一限制因子,然后依次为S,Mg,K,N。盆栽不施P、S、Mg、K、N,作物分别减产52.76%、37.88%、37.60%、34.60%、31.71%。因此,该黄竹林应加强有机肥的施用,在施足N、P、K肥的同时,应配合施用一定数量的S、Mg肥,实现黄竹林的平衡施肥。

The main soil nutrients of Bambus arigida forest in Ganxian County ,Jiangxi Province were as-sessed by soil nutrient systematic approach ,using Sorghum bicolor as the indicator plant so as to evaluate the soil nutrient status and its limiting factors .The results showed that organic matter content was low in the soil .P , S,Mg,K,N were severely deficient,but Zn was slightly low.Ca,B,Cu,Fe,Mn were abundant.The amount of the soil adsorption and fixation of P ,S,K was large and that of Zn,Cu was small and B,Mn were hardly ad-sorbed and fixed .The results of pot experiment showed that P was the first limiting factor in Bambus arigida forest soil nutrients,and then followed by S,Mg,K,N.Potted without P,S,Mg,K,N,the crop yield reduced by 52.76%,37.88%,37.60%,34.60%and 31.71%,respectively.Thus,the Bambus arigida forest needs more ap-plication of organic fertilizers.Applied with adequate N,P,K fertilizers,a certain amount of S,Mg fertilizers is needed,so as order to achieve balanced fertilization .
