- 摘要:
- 以种植在宁夏中卫市香山干旱山区压砂地根龄5a生的同心圆枣树(行间套种西瓜)为试材,研究了压砂地不同间作模式对土壤含水率、西瓜的根系生长及产量、产值和枣树根系、树体发育及坐果的影响。结果表明:在裸砂地中每667m2补水19.3m3,压砂地土壤含水率提高约1.7%,西瓜根系向上层区域(砂层0~20cm)和向下层区域(40~60cm)的根系共计增加了8.7%,根系数量(剖面0.6m2内)增多28%,西瓜产量提高66.0%,产值增加300%。在枣瓜间作模式中,在同样补水栽培管理条件下,枣树8m行间间作2行和间作3行西瓜,在大于3kg商品瓜产值(净面积)方面,比裸砂地补水处理产值分别提高5.9%和降低7.3%;间作2行西瓜的枣树比间作3行西瓜的枣树,单株坐果量和单株产量分别增加17.1%、22.6%。
