结合阿克苏地区土壤的基本供肥特点和丰产园果农施肥平均水平及高限水平设置不同的施肥梯度,对不同处理茎粗和枣吊生长、产量、品质及效益进行测定和分析。结果显示:随着施肥量的增加,茎粗、枣吊的增长量及灰枣产量和品质均呈现先上升后下降的趋势。在总施肥量2.50~5.50 kg/株范围内,随着施肥量的增加,灰枣产量随之增加,增产效果显著;在枣树总施肥量8.00~10.00 kg/株范围内,灰枣产量随施肥量的增加略有下降,说明过量施肥易造成树体营养元素的失衡,在养分离子之间存在着拮抗作用,从而影响树体对养分的吸收,进而影响产量。在一定施肥范围内枣树产量随着施肥量的增加而增加,超过一定范围,产量则随施肥量的增加而减少。
According to the basic characteristics of fertilizers for soils in Aksu region and the fertilization gradients of fertilization in high yield orchards, the growth, yield, quality and benefits of different treatments of stem diameter and date were measured and analyzed. The results showed that with the increase of fertilizer amount, the growth of stem diameter, jujube hanging height and the yield and quality of gray jujube rose at first and then decreased. Within the range of total fertilization 2.50 ~ 5.50 kg / plant, with the increase of fertilization amount, the yield of ash jujube increased and the yield increase was remarkable. Within the range of 8.00 ~ 10.00 kg / plant, the yield of ash Fertilizer amount increased slightly decreased, indicating excessive fertilizer easily cause imbalance of nutrient elements in the tree, there is antagonism between nutrient ions, thus affecting the tree’s nutrient absorption, thus affecting the yield. In a certain range of fertilization jujube yield increased with the increase of fertilizer over a certain range, the yield decreases with the increase of fertilizer.
