【目的】优选出可供干旱区绿洲灌溉条件下枣树施用的生物肥种类。【方法】以干旱区绿洲的成龄密植骏枣园为研究对象,通过比较几种肥料对枣树生长发育、枣果产量、经济效应以及土壤化学性状的影响,分析枣树对不同肥料处理的施肥效应差异。【结果】(1)在枣树树体生长量方面,处理1和处理2表现较好;(2)处理1的单株产量最高,较处理4高出15.42%,而各处理间枣果品质无明显差异;(3)处理1的土壤养分含量要高于其它处理,而重金属含量居中,各处理无明显差异;(4)通过经济效应分析表明,处理1的经济效益最好,达57.76元/株。【结论】就在干旱区绿洲宜选择处理1的生物肥种类,但其最佳施肥量需进一步开展研究。
【Objective】 The optimum types of bio-fertilizer for jujube tree under oasis irrigation in arid area were optimized. 【Method】 Aging juveniles in oasis of arid region were studied. By comparing the effects of several fertilizers on the growth and development of jujube, the yield of jujube, the economic effect and the chemical properties of jujube, the effects of jujube on the treatment of different fertilizers Fertilizer effect differences. 【Result】 (1) In the jujube tree growth, treatment 1 and treatment 2 performed better. (2) The treatment 1 had the highest yield per plant, 15.42% higher than that of treatment 4, while the quality of jujube (3) The content of soil nutrient in treatment 1 was higher than that in other treatments, but the content of heavy metals was middle, and there was no significant difference in each treatment. (4) Through the economic effect analysis, the economic benefit of treatment 1 was the best, reaching 57.76 yuan / Strain. 【Conclusion】 In the oasis of arid area, the type of biological fertilizer should be selected to treat 1, but the optimal amount of fertilizer should be further studied.
