摘要
应用人为控制土壤水分的方法，研究了1年生台湾青枣苗在不同土壤水分条件下的生长和生物量的分配。结果表明：地上部分和地下部分生物量均随着土壤含水量的降低而升高；根冠比随着土壤含水量的降低而降低；在元谋干热河谷地区种植台湾青枣苗的土壤含水量以田间持水量的40％～60％为宜。
Controlling soil moisture factitiously, the growth and biomass allocation of one-year old Zizyphus rnauritiana lam seedlings growing under different soil moisture conditions were studied. The results showed that the biomass of both overground segment and underground segment reached the maximum with soil moisture content decreasing. Its Root/Shoot Ratio was decreased with soil moisture content decreasing. Soil moisture content of the land accounting for 40% - 60% of field moisture capacity was the most suitable for Zizyphus mauritiana Lam seedlings in dry and hot river valley in Yuanmou.
