The saving-water effect of Radish and Cabbage under PFM and appropriate irrigation,and the drought-resisting of radish seedling which seed was soaked by CaCl_2 were systematicly reseached by field observation and the experiment in door.The main results were summaried as follows:The soil temperature of 0~20cm cultivated layer was increased 3-4.5℃ in early growth period was only 1℃ in late growth period by PFM;there was more water saved up to 20.84mm in 0~60cm soil layer by PFM than no PFM in the early growth period of Radish;the yield and water use efficiency of Radish in L4 were exceeded respectively 10.1% and 21.9% of that contrast, the yield and water use efficiency of Cabbage in G4 were exceeded respectively 8.7% and 26.58% of that contrast, under PFM and appropriate irrigation.

主要研究结果如下：地膜覆盖在植株生长前期耕作层平均可增温3～4.5℃，在生长后期增温幅度减小，仅有1℃左右；地膜覆盖在植株生长前期可有效的保持土壤水分，在萝卜生长前期，使0～60cm土层内多储水20.84mm；在覆膜不灌水充分利用自然降雨的条件下生产萝卜，可比裸地正常灌水萝卜增产10.1%，水分利用效率提高21.9%；覆膜只浇一水生产甘蓝，可比裸地正常灌水生产甘蓝增产8.7%，水分利用效率提高26.58%。
