摘要/Abstract

摘要： 比较了4个水分梯度3年生台湾青枣(Zizyphus mauritiana Lam.)的树高生长动态、地径生长动态、新梢生下量、枝粗生长量、叶面积、叶面积指数、座果率、平均株产量、叶片含水率和根系含水率等，通过主成分分析法和R型因子综合分析法确定了适合台湾青枣生长的最优土壤含水率。结果表明：第3种水分处理(土壤含水率为田间持水量的70%～85%)的台湾青枣对水分的响应最好，对水分的响应排序值是56.147；其次是第4种水分处理(土壤含水率为田间持水量的85%～100%)，其值为41.506；最后是第1种水分处理(土壤含水率为田间持水量的40%～55%)，其值为34.545。由此可以得出，在金沙江干热河谷地区种植台湾青枣的最佳土壤水分是土壤含水率达到田间持水量的70%～85%。

Abstract: This paper studied the height growth, basal diameter growth, new branch growth, branch diameter growth, leaf area, leaf area index, fruit setting rate, yield per plant, leaf water content, and root water content of 3 years old Zizyphus mauritiana Lam. in the dry and hot valley of Jinsha River under 4 levels of soil moisture content. Principal component analysis (PCA) and R-factor analysis were made to determine the optimal soil moisture condition for Z. mauritiana growth. The results showed that 70%-85% of field capacity was most appropriate, with a compositor value responding to soil moisture being 56.147, followed by 85%-100% and 40%-55% of field capacity, with the compositor value being 41.506 and 34.545, respectively. It was suggested that 70%-85% of field capacity was the most suitable soil moisture content for Z. mauritiana in the dry and hot valley of Jinsha River.
