摘要
通过对保水剂和旱地龙这两种抗旱节水剂在苹果生长上的试验研究,分析了抗旱节水剂集成应用对土壤含水率、苹果产量、苹果品质(主要指可溶性固形物)的影响。结果表明,施用抗旱节水剂可增加土壤含水率和果实品质,增产达13365 06～19036 58kg/hm2,增加纯经济效益20570～34750元/hm2;水分利用效率提高,每1hm2节水892m3,同时对抗旱节水剂应用条件下的果树灌溉制度进行了研究,提出了不同降雨年型的灌溉制度。
The experiments on apple growth and its efficient water use by using Water-Holding Agents,Fulvic Acid were carried out. The effects on soil moisture, output and the quality of apple were studied. The experiment data show that the drought resistant and water saving agents could effectively improve the soil moisture and increase the quality of the apple,the fruit tree could increase its drought-resistant potential and its production which increased by 13 365.06～19 036.58 kg per hectare; The economic benefit increased by 20 570～34 750 yuan per hectare; The water use efficiency also improved, and the irrigative water saved by 892 m^3 per hectare. Simultaneously,the experiments on fruit tree irrigation schedule by using drought resistant and water saving agent,conclude the irrigation schedule of different rainfall year.
