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%。

On the basis of summarizing separation method of acetic acid-water system, we studied the azeotropic distillation process of acetic acid-water system, selecting butyl acetate, isobutyl acetate and isopropyl acetate as entrainers. The influence of packing height, ratio of water to entrainer and acetic acid initial concentration to separation effect of azeotropic distillation was studied in detail. Simulation calculations of general distillation and azeotropic distillation were carried out. The influence of reflux ratio, theoretical plate, feed position, feed temperature and feed concentration to distillation process were discussed. Preferred process operation parameter, which had guiding meaning to practical production of distillation process were obtained. Basic data for the process amplifying design of azeotropic distillation tower were provided. Invest and operation energy consumption of two distillation methods were compared. The elementary technical design of azeotropic distillation tower was carried out on the basis of result of simulation calculation. The type of major auxiliary equipments and inner parts of packed tower were selected.The research results are as follows:(1) Butyl acetate, isobutyl acetate and isopropyl acetate could be selected as entrainer, and separation effect was near.
