西瓜(Citrullus Lanatus)是约旦谷的主要灌溉蔬菜之一。随着滴灌和地膜覆盖的引入，西瓜产量在过去几年里有所增加，特别是在高原地区。本试验旨在研究不同地膜覆盖对作物水分利用和西瓜产量的影响。收集了土壤温度数据，研究了不同覆盖条件下土壤温度的波动和变化程度。并对其根系密度和分布进行了研究。结果表明，不同处理之间的施水量和产量存在显著差异。透明覆盖、平均总供水量为44.3 cm时产量最高(平均为55.3MT/HA)。而在黑色地膜下，在总灌水量为40.1 cm的情况下，平均产量为13.3MT/ha。在无覆盖条件下，仅获得10.4MT/HA，最大总供水量为51.2 cm。根系分布和密度差异不显著。覆盖处理的土壤温度高于不覆盖处理。测定的热量单位表明，透明覆盖和黑色覆盖处理之间没有太大差异。
Watermelon (Citrullus Lanatus) is one of the major irrigated vegetables in the Jordan Valley. Watermelon production has increased in the last few years with the introduction of trickle irrigation and plastic mulching, especially in the highlands. In this experiment it is intended to study the effects of different plastic mulching on crop water use and on yields of watermelon. Soil temperature data was also collected in an attempt to study its fluctuation and degree of change under different mulching. Also studied were the root density and distribution. Results indicate significant differences in water applied and in yields between treatments. Highest yield (average = 55.3 MT/HA) was obtained under transparent mulch and with average total water supply of 44.3 cm. Whereas under black mulch an average yield of 13.3 MT/HA was obtained although 40.1 cm total water was applied. Under no mulch, only 10.4 MT/HA was obtained with a highest total water supply of 51.2 cm. Root distribution and density did not show any significant differences. Soil temperature under mulched treatments were higher than those non-mulched. Heat units determined showed no big difference between transparent and black mulched treatments.
