摘　　要：通过6种雨养种植模式与常规种植模式的效果对比研究,结果显示,水分对麻疯树生长影响较大,采用雨养种植模式都能有效截留雨水,促进麻疯树快速生长,但竹节沟种植模式对麻疯树增长高度最大,达到228.3 cm,是对照的1.5倍,其次是隔坡水平沟模式;同样采用雨养种植模式的麻疯树自10月才开始有落叶,较对照推迟了1个月,其中竹节沟模式和隔坡水平沟模式的麻疯树11月才开始落叶,较对照推迟了2个月,而且竹节沟模式没有完全进入休眠状态,仍然表现为生长状态。说明水分对麻疯树生长起到关键性作用,在干热区种植麻疯树时,雨养种植技术模式具有很强的实用性,是最经济有效的原料基地建设方法。6 rain-fed cultivation mode was compared in this study. The results showed that moisture content had a great impact on the growth of Jatropha curcas, so rain-fed cultivation mode could effectively trap the rain and stimulate growth. Bamboo-ditch cultivation mode, more 1. 5 times than CK, had the most prominent impact on the height （288.3cm）. The slope level furrow mode was in the second place, and its defoliation was in October and delayed 1 month than CK. Under Bamboo-ditch cultivation mode and the Slope level furrow mode, the defoliation was in November, 2 month later than CK. Jatropha curcas in amboo-ditch cultivation mode did not enter the state of dormancy entirely, and were still growing. The rain-fed cultivation technology mode was practical when Jatropha curcas were planted in arid-hot area, and the method also was a economic and effective approach for building raw material base.
