运用标准竹和间接收获法来测定1~2年生浙南绿竹地上生物量,分析了1~2年生浙南绿竹地上部分含水率及生物量分配情况,以及竹秆各段含水率及生物量分配情况,结果表明:1年生地上部分各器官含水率以竹秆最高,2年生地上部分各器官含水率以枝为最高;1~2年生鲜、干生物量的分配以秆为最高;1~2年生竹秆含水率随高度增加而逐渐降低,竹秆鲜、干生物量分配比例均从秆基部向梢部逐渐降低;运用线性函数拟合秆生物量数学模型的相关性较高,可以用来估算1~2年生浙南绿竹竹秆生物量。
Using standard bamboo and indirect harvesting method, the above-ground biomass of 1-year-2-year-old green bamboo was measured. The above-ground water content and biomass allocation of 1 to 2-year-old green bamboo were analyzed, and the moisture content and biomass The results showed that: the moisture content of organs in aerial parts of 1-year-old was the highest in bamboo stalks, and the moisture content of organs in 2-year-old parts was the highest. The fresh and dry biomass of 1-year and 2-year- The water content of 1-year-2-year-old bamboo stalks gradually decreased with the increase of height, and the proportion of fresh and dried biomass of bamboo stalks gradually decreased from the base of the stalks to the tip of the stalks. The correlation of stalks biomass mathematical model fitted by linear function was high, Can be used to estimate 1 to 2 years old green bamboo bamboo biomass.
