运用PV技术研究树种的抗旱性
Study on the Ability to Drought-Resistance of the Trees in PV Technology
【摘要】 以生长在呼和浩特地区的紫丁香、榆叶梅、珍珠梅为材料,用Hammel逐渐升压法测定植物叶水势绘制Pv曲线并计算各种水分参数。通过对各项抗旱性生理指标的综合研究,结果表明在整个生长季里,抗旱能力排序为:紫丁香>榆叶梅>珍珠梅。
【Abstract】 Taken Syringa oblata Lindl.、Prunnus triloba Lindl and Sorbaria sorbifolia(L.)A.Br. as the materials growing in Huttot area, we determined the leaf water-potential with a Hammel pressure-rise gradual method and drawn up Pv curve to calculate all kinds of water parameters. Through studying each drought resistance physiological indicators we can learn the result that the ability to drought-resistance is Syringa oblata Lindl. >Prunnus triloba Lindl >Sorbaria sorbifolia(L.)A.Br. throughput the grown season.
