中文摘要	【目的】研究不同施肥对成龄红枣生长及产量的影响,为新疆南疆干旱地区成龄红枣的合理施肥提供依据。【方法】通过不同施肥量的肥料试验,研究枣树叶片SPAD值、枣吊、果实横纵径、单果重、产量等生理性状与施肥量之间的关系,确定针对于南疆成龄红枣的合理施肥量。【结果】114 kg/667 m~2施肥处理的红枣枣吊、单果重、产量等生理性状均明显优于其它施肥处理,叶片SPAD值最低。随着施肥量的增加,红枣产量与施肥量关系为Y = -25.647X~2 + 134.43 X + 315.54, R~2 = 0.743 6,施肥处理3产量达到最高。【结论】在供试条件下,合理的施肥量为尿素70 kg/667 m~2、硫酸钾44 kg/667 m~2,红枣产量可达535.76 kg/667m~2,滴灌施肥与传统施肥相比,尿素、硫酸钾肥料配合合理,能有效提高红枣产量和品质。
英文摘要	[Objective] To provide the basis of the reasonable fertilizer rate on mature jujube in arid areas of Southern Xinjiang. [Method]Through the application of different fertilizer rate of N, P, K, the relationship between SPAD, bearing branch length, the vertical and horizontal size of fruit, weight of single fruit, yields and fertilizer rate were studied to obtain the reasonable fertilizer rate of mature jujube in Southern Xinjiang. [Result] The results showed that the bearing branch length, weight of single fruit, the yields of the jujube in the 114 kg/667 m~2 fertilizer rate were significantly better than any other fertilizer treatments, and the value of leaf SPAD reached the minimum. With the fertilizer increasing, the relationship between fertilizer quantity and production efficiency was negative, the function was Y= -25. 647 X~2 + 134. 43 X + 315. 54, R~2 = 0.743 6, production and water productivity in the treatment 3 was the highest.[Conclusion] Under such conditions, the reasonable fertilizer rate was urea 70 kg/667 m~2 and sulfate 44 kg/667 m~2, in which the mature jujube yields reached to 535.76 kg/667 m~2. When drip irrigation was compared with traditiorial fertilization, urea, potassium and sulfate fertilizer were reasonable and could improve the yield and quality of mature jujube.
