摘　　要：１９９０～１９９３年，在银川地区对２～４年生苹果树喷布羧甲基纤维素和ＦＹ－１型林木果树保水剂，以预防果树枝条失水。结果表明，１１月底至１２月初和３月初喷２次保水剂与１１月底喷保水剂、３月初喷１２０倍羧甲基效果均佳果树受伤害率仅２．３２～４．１６％，明显低于人工埋土的４６．８８％，成本以后者较适宜（０．３～０．５元）。From 1990 to 1993. Carboxymethy Cellulose(CMC) and Moisture-conserving Emulsion(MCE) Fy-1 were Sprayed upon fruit trees at ages between 2 and 4 years to prevet the tree branches from moisture Loss in wintering period around Yinchuan area. The results indicated that spraying the MCE once between the end of November and the beginning of December and once again in the beginming of March, and Spraying the MCE in the end of Novmber and 120 times of the CMC in the beginning of March all produced good results with a damage rate of the fruit trees from 2 .32% to 4.16% only. The rates are obviously smaller than the 46.88% of the branch moisture-losing rate of soilburying protection methol, but the latter case needs less cost (0.3 Yuan RMB-0.5 yuan RMB for each apple tree).
