| 摘 要： | 探讨了在有效硅含量水平较低的流纹岩风化物发育的土壤上，中、低产毛竹林施用硅肥的效应。试验结果表明，在中、低产毛竹林中施用硅肥是没有增产效果的；土壤中有效硅的含量管较低，但足够毛竹生长对硅素的需要。综合诊断施肥法（DRIS）对硅素营养的诊断结果提示，即使在具有较高竹材产量的竹林中，无论施用N、P、K三要素肥料与否，硅的营养况仍然是接近适宜水平的。鉴于中因大多数竹林的实际情况，认为目前生产上尚无施用硅肥的必要。

| Abstract: | Silicon fertilizer application was studied with bamboo achys pubescens) stands of mid-low yield on the rhyolite weathing crust soil which has lower available silicon content in Anji county, Zhejiang Province. Randomized complete block design (RCBD) was used in the field plan. The results of statistical analysis for 12 experimental plots are as follows: Applying silicon fertilizer to increase bamboo yields was ineffective despite of lower soil available silicon content (4.62 mg/100g soil). Diagnosis and recommendation integrated system (DRIS) was used for evaluating nutrient status of Si for bamboo function leaves, it indicated that Si nutrient level was suitable in the midst of stands, even if bamboo stands may obtain higher yield for N, P and K fertilizer system. On the basis of realitical status of widespread bamboo natural range in China, applying silicon fertilizer is not necessary. |
