摘要
【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 ] This project aims to select biological fertilizer types that are suitable for jujube fertilization under the condition of arid oasis irrigation. [ Method] The grown -up and densely -planted jujube is taken as the research object, and through comparing several kinds of fertilizer on the growth and development of Chinese jujube, jujube fruit yield, economic effect and the influence of soil chemical properties, Chinese jujube fertilization effects of different fertilizer treatment differences are analyzed. [Result] （1） In terms of jujube tree growth, treatment 1 and treatment 2 are best; （2） Treatment 1 has the highest output , which is 15.42% higher than that of treatment 4, and there are no obvious differences of jujube fruit quality between the groups; （3） Treatment one＇s soil nutrient content is higher than those of the other processing, and heavy metal content of this treatment is in the middle and each treatment has no obvious difference; （4） Economic effect analysis shows that the economic benefits of processing 1 is the best, up to 57.76 yuan/strain. [ Conclusion ] In terms of several volunteers biological fertilizer in this test, in arid area oasis, treatment 1 of biological fertilizer should be selected, but the best fertilizer rate remains to be studied further.
