摘要
在人工控制土壤贮水量的条件下,进行豌豆抗旱栽培试验,通过观测土壤贮水的生产能力及豌豆的耗水量与耗水系数分析,结果表明,豌豆全生育期在土壤贮水160mm的情况下,可获得50kg/亩以上的产量。豌豆作为耗水较少的作物在半干旱地区的作物种植中应占有一定的位置。但在降水较多时,其耗水系数升高,水分生产效率下降,因此,在半干旱降水偏多地区,则又应适当控制其种植面积。
Drought resistant cultivation of pea plants was conducted under artificialmoisture control.AISO the productive ability of soil moisture storage,pea waterconsumption and water consumption coefficient were analysed based on observa-tion and determination.The results showed that over 50 kg/mu of pea yieldscan be obtained under 160 mm of soil moisture stored in soils.Pea is a kindof less water consumption crop,which should have a certain place in the culti-vated crops in the semiarid areas.Water coefficient of Pea rises while waterproductive efficiency goes down gradually when there is much rainfall.For thisreason,the sown area of pea crop should be properly controlled in the arid andsemiarid areas where there is relatively much rainfall.
