黄花蒿耗水及生长规律试验研究

黄花蒿可作为干旱地区收复弃耕地的先锋植物。通过小区试验，对黄花蒿耗水规律、生长过程和生态效应进行了研究。试验结果表明，黄花蒿的生长可分为发芽、展叶、分枝、现蕾、开花、结实6个阶段，其中分枝期长，相应的耗水强度最大；黄花蒿株高和侧枝生长对土壤水分状况敏感，具有较强的抗逆性和环境适应性；同时，其主茎和侧枝较长，覆盖度大，具有一定抗风沙能力。该研究对干旱区生态建设有一定帮助。

Experiments on the Water Consumption and Growth of Artemisia annua. L

The Artemisia annua. L is taken as a plant available to live in abandoned land in arid region. With the experiments in plots, the Artemisia annua. L was researched on its growing features, ecological effects, and its water consumption. It was found that the growth course of the Artemisia annua. L consisted of six periods, such as germination, leaves spread, twigs growths, budding, flowering and fruiting. Of which the twigs growth lasted for a long time, corresponding water consumption was the largest of other periods. The growth of the vegetable stem and twigs was sensitive to soil water conditions. It had strong resistance and tolerance to environmental factors. Then by longer main stem and branches, and large canopy, the vegetable had considerable capability to hinder wind-drift sands. Researches in this paper are beneficial to ecological development for arid region.
