为了解夏播绿豆不同生育期的耗水特性和土壤水分变化特点,以冀绿2号、冀绿7号、冀绿9号和白绿522为试验材料,分别在足墒和欠墒条件下,对绿豆全生育期的耗水规律及分布进行了初步研究。结果表明:绿豆生育期总耗水量仅为同期降水量的1/2;随着生育期的延后,不同品种和墒情处理的绿豆耗水量均呈降-升-降的变化趋势,其中苗期和结荚盛期耗水量较大,绿豆相对日耗水强度基本呈先升高后降低的变化趋势,其中结荚盛期相对日耗水强度最大;不同品种间以冀绿2号的耗水量和相对日耗水强度最大,不同墒情处理对绿豆总耗水量影响不明显,但是足墒条件下可明显缓解由于前期干旱引起的植株生长受抑;绿豆的耗水层主要集中在0~70 cm土层,其中0~50 cm土层为强耗水层。

In order to investigate the characters of change of soil water and water deprivation of summer sowing mung bean, the experiment of the law and distrubution of water deprivation of mung bean was conducted with Jilv No.2, Jilv No.7, Jilv No.9 and Bailv 522 under the conditions of enough moisture and shortage moisture.The results showed that during the whole period of mung bean, the total water consumption was only half of the synchronous precipitation.With the delay of growth period, the water consumption of different varieties and soil water treatments showed decreasing-increasing-decreasing tread, which were higher at seedling stage and pod bearing period, daily relatively water consumption intensity was increased first and then decreased, and the maximum was appeared at pod bearing period.The water consumption and daily relatively water consumption intensity of Jilv No.2 were all highest and with little differences between enough moisture and shortage moisture , but enough soil moisture regime could obviously relieve the plant growing restraintation aroused by drought.0 -70 cm layer of the soil was the main water deprivation layer for mung bean , and 0-50 cm was the stronger layer.
