不同水肥处理对梨枣几种形态指标的影响

研究了不同水肥处理(对照、浇水、浇完全营养液、施复合肥、施复合肥加浇水)对梨枣生长期叶片厚度、叶面积、百叶重、枣吊长度、枣吊叶片数的影响,结果表明:与对照相比,不同水肥处理均能增加梨枣的枣吊长度和枣吊叶片数,其中施复合肥加浇水效果最好;浇完全营养液、施复合肥、施复合肥加浇水处理后均能显著增加梨枣的百叶重,叶面积和叶片厚度。表明施肥结合灌溉能显著促进梨枣枣吊和叶片的生长,有利于提高梨枣的产量。

Effect of Different Irrigation and Fertilizer Treatments on the Morphological Index of Pear Jujube

In different irrigation and fertilizer management, the changes of the length of bearing branch, the weight per one hundred leaves, the leaf area, the leaf thickness and the number of leaf on bearing branch of pear jujube were determined. The results showed that：compared with the control, the length of bearing branch and the number of leaf on bearing branch of pear jujube is significantly increase by different irrigation and fertilizer management, of which the best is compound fertilizer and watering; The weight per one hundred leaves, the leaf area and the leaf thickness of pear jujube is significantly increase by Irrigated the complete nutrient solution, compound fertilizer and compound fertilizer with watering. It is indicated that the growth of bearing branch and leaf of pear jujube can be significantly increase and help to improve the production of pear jujube by the fertilization combined with irrigation.
