Abstract

Abstract:

【Objective】To study the response of growth and fruit formation to water, nitrogen, phosphorus and potassium of Korla fragrant pear in the hope of providing theoretical.【Methods】Basis for improving quality and increasing yield of Korla fragrant pear. Four factors of water, nitrogen, phosphorus and potassium were set in the test, among which, two levels of water were set. Nitrogen, phosphorus and potassium were set at three levels, namely water (2,400 kg/hm²; 3,600 kg/hm²), nitrogen (150 kg/hm²; 300 kg/hm²; 450 kg/hm²), Phosphorus (1,12.5 kg/hm²; 225 kg/hm²; 337.5 kg/hm²), potassium (55 kg/hm²; 110 kg/hm²; 165 kg/hm²) to determine the growth, fruit quality and yield of pear trees. 【Results】(1) The growth amount of W₁N₂P₃K₁ branch was the highest, and the diameter of W₂N₃P₂K₁ branch was the largest. The range analysis of branch growth dynamics of Korla Fragrant Pear showed that W₂N₂P₂K₁ had the best effect on branch growth, and the results of branch diameter were consistent with the actual measurement. (2) It was seen that the growth trend of W₁N₂P₃K₁ fruit shape was closest to the fitting growth curve, R² was closest to 1, which was most consistent with the growth law. (3) W₁N₁P₂K₃ treatment ranked the highest, with the best fruit quality performance. (4) Its yield under W₁N₃P₃K₃ was the highest and the fruit weight of Korla fragrant pear was relatively good. 【Conclusion】Considering pear tree growth, fruit quality and actual yield, the growth, fruit quality and yield of Korla Fragrant Pear treated with W₁N₃P₃K₃ are better.

Key words: Korla Fragrant Pear; water and fertilizer coupling; grow; fruit quality; yield

摘要：

【目的】探究库尔勒香梨生长和果实的形成对水、氮、磷、钾的响应,为库尔勒香梨提质增产提供理论依据。【方法】以库尔勒香梨为试验对象,设置水、氮、磷、钾4个因素,其中水设2个水平;氮、磷、钾各设3个水平,即水(2 400、3 600 kg/hm²)、氮(150、300和450 kg/hm²)、磷(112.5、225和337.5 kg/hm²)、钾(55、110和165 kg/hm²),测定梨树生长量、果实品质和产量。【结果】(1)处理W₁N₂P₃K₁枝条生长量最高,处理W₂N₃P₂K₁枝条直径最大。处理W₂N₂P₂K₁对于枝条生长量表现最佳,枝条直径结果与实际测量一致。(2)处理W₁N₂P₃K₁果形生长趋势最接近拟合生长曲线,R²最接近1,最符合生长规律。(3)处理W₁N₁P₂K₃得分排名最高,果实品质表现最佳。(4)处理W₁N₃P₃K₃库尔勒香梨产量最高且单果重表现相对较优。【结论】综合梨树生长、果实品质及实际产量,优选出W₁N₃P₃K₃处理下库尔勒香梨生长、果实品质及产量表现较优。
