摘要
通过定位试验,研究了不同覆盖方式对山地枣林土壤温、湿度及枣树生长的影响。结果表明,几种保墒措施的土壤水分,随时间变化和剖面分布,相对于对照均有明显提高,其中地下25 cm处铺玉米秸秆+地表铺玉米秸秆和地膜覆盖处理效果最好,但是二者土壤含水量相差0.72%。地膜覆盖有明显的增温效应,覆盖玉米秸秆对温度的影响则表现出"双重"效应:高温时具有降温效应,低温时具有保温特点。不同的保墒处理对枣树生长有不同影响,但各处理的新梢生长量、干周净增量、百叶鲜物质量、平均单果重比对照均有提高。
The experiments were used for the study on soil moisture, temperature of upland jujube and jujube growth under difference mulching ways by location test. The result indicated that deep straw mulch with surface straw mulch and polythene mulch showed better effect on soil moisture conservation, but soil moisture discrepancy is only 0.72%. polythene mulch increase soil temperature, straw mulch enhance and hold soil temperature in low 0nd high temperature. Different soil moisture conserving treatments have different effect on growth of jujube, comparing with bareground, they showed better effect on growth and development of jujube.
