nutrient availability

The leaf size, leaf dry weight, specific leaf area and specific leaf weight were high in ungrazed pasture with low nutrient availability.

不放牧的封育草地土壤养分资源相对贫乏，但植物的叶片大小、叶干重、比叶面积和比叶重均较大。

A pot experiment with three levels of nutrient ( N, P, K) supply was carried out to investigate clonal plasticity of stoloniferous herb Duchesnea indica Focke in response to nutrient availability. The plants had greater biomass at higher levels of nutrient availability.

为了研究匍匐茎草本植物对基质养分供应水平的克隆可塑性，在一栽培实验中匍匐茎草本植物蛇莓（DuchesneaindicaFocke）经历了高、中、低养分（N，P，K）水平的环境处理。
