摘要: 利用校正过的棉花模拟模型COTTON2K对华北平原和新疆的棉花生产和耗水进行了模拟,分析2个地区棉花的耗水特征。结果表明,新疆石河子地区在水分充分供给条件下石河子的耗水量为655 mm,而禹城的耗水量为541 mm;石河子的平均产量几乎为禹城的2倍;同时分析了2个站点产量和耗水量的关系以及不同生育期耗水规律和降雨的同期性,结果表明禹城的降雨能满足棉花80%的需水量,灌溉时期主要集中在苗期和蕾期;石河子的降雨仅能满足棉花需水的21%;另外,石河子的水分利用效率大于禹城,但是新疆的棉花生产基本依靠灌溉,成本较高。

Abstract: Based the modified cotton simulation model COTTON2K, comparison of growth and water use in thedifferent region: North China Plain and Xinjiang was done. The result showed that evapotranspiration ( ET) was 655mm for Shihezi in Xinjiang and 541 mm for Yucheng in North China Plain. The yield in Shihezi is almost twice ofthat in Yucheng without water stress. At the same time, the relation between precipitation and ET were studied indifferent growth stages for the two areas. It showed that precipitation can satisfy 80% of water use for Yucheng, and21 % for Shihezi. Water use efficiency for Shihezi is higher than that in Yucheng. But cost of cotton production ishigher for Xinjiang due to its higher dependence on irrigation.
