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 C
3 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 C
2>C
3>C
1>CK, and the length of jujube hanging was C
3>C
2>C
1>CK, and the yields of C
1, C
2 and C
3 treatments increased by 6.34%, 17.74% and 18.44%, respectively, compared with CK treatment. (4) The C
2 treatment was the best, followed by the C
3 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.
