摘  要:
通过对日光温室甜瓜幼苗根区不同温度处理,研究了根区温度对甜瓜幼苗生长的影响。结果表明:根区低温使甜瓜幼苗叶片数、株高、叶面积、干物质积累、根系活力、植株含水量、水分利用效率降低,而根冠比增加。

摘  要:
Experiments of different root zone temperature treatments were carried out at seedling stage of muskmelon in solar greenhouse.Comparison of low temperature treatment with optimal temperature treatment indicated that leaf quantity,plant height,leaf area,dry weight of shoot dry weight of root and root activity,water content,water use efficiency of muskmelon seedlings decreased,while root∶shoot ratio of muskmelon seedlings increased.
