Abstract

Abstract:

【Objective】 The objective of this study is to explore the effects of different width mulching patterns on jujube trees in Hotan Prefecture, Xinjiang. 【Methods】 In this study, three kinds of ground cloth covering jujube orchards with different widths were designed to study the effects of soil temperature, soil moisture and growth of jujube trees in jujube orchards compared with the control group without ground cloth. 【Results】(1) Different treatments in jujube orchards had a warming effect on soil temperature, and the ground temperature of each layer of different width cloth treatments increased, but the effect of air temperature on soil temperature decreased with the increase of depth; (2) The three kinds of ground cloth mulching had a certain moisture retention effect, and the water retention effect of C₃ was better than that of CK. (3) Different widths of ground covering were beneficial to the growth of jujube trees, and the length of new shoots was C₂>C₃>C₁>CK, and the length of jujube hanging was C₃>C₂>C₁>CK, and the yields of C₁, C₂ and C₃ treatments increased by 6.34%, 17.74% and 18.44%, respectively, compared with CK treatment. (4) The C₂ treatment was the best, followed by the C₃ treatment. 【Conclusion】 The application of horticultural ground cloth to jujube orchard mulching can improve soil temperature and moisture content, and has a good moisture retention effect on soil, which can promote the growth and yield of jujube trees.

摘要：

【目的】探究不同宽度地布覆盖模式对新疆和田地区枣树的影响。【方法】以新疆和田地区成龄骏枣为研究对象,分别设计3种不同宽度地布覆盖枣园与不铺设地布的对照组相比,研究其对枣园土壤温度、土壤水分和枣树生长的影响。【结果】(1)在枣园进行不同处理均对土壤温度产生了增温效果;不同宽度地布处理的各层地温均有所增加,但随着深度的增加气温对土壤温度的影响越小;(2)3种地布覆盖均有一定的保墒效果,与CK相比,C₃的保水效果较好。(3)不同宽度地布覆盖均能有利于枣树的生长,新梢长度表现为C₂>C₃>C₁>CK;枣吊长度表现为C₃>C₂>C₁>CK;在产量方面,C₁、C₂和C₃处理的产量分别比CK处理增加了6.34%、17.74%和18.44%。(4)C₂处理最优,C₃处理次之。【结论】园艺地布应用于枣园覆盖,可以改善土壤温度和提高含水率,对土壤具有较好的保墒作用,促进了枣树的生长及产量。
