甘肃民勤沙区灌水方式对沙枣树生长的影响

Influence of Irrigation Method on Elaeagnus Angustifolia Trees Growth in Minqin County

为使甘肃民勤县沙区生态环境重建工作能够以治沙养治沙、良性循环、滚动发展,2004—2007年在该区对沙枣树进行了栽培和喷灌、滴灌田间试验。结果表明:沙枣树在沙漠土壤水分较好或水源较方便的条件下,可以作为生态环境恢复与重建的果木类树种;滴灌对新苗灌水的适宜灌溉定额为40 L/株,随着植株的成长,要增加灌水量,才能取得较好的经济效果;施固体肥对沙枣苗的成活率、生长指标的影响作用不显著,因此不宜大面积推广使用。

In order to explore ecological environment reconstruction work to keep on sand control in the Minqin County of Gansu,achieving beneficial circulation,rolling development way,the cultivation and spray,drip irrigation field of Elaeagnus Angustifolia were being test in 2004-2007.The results show that,elaeagnus angustifolia can be used as the ecological environment restoration and reconstruction species of fruit trees,in desert soil more moisture,or water more convenient conditions;Drip irrigation quota of bud spring plant is suitable for 40 L/plant,with the plant to grow up to increase the irrigation quota,which can receive the good economic effect;Solid water is no significant to seedling survival rate and growth indices of the impact of elaeagnus angustifolia,so it is not suitable for widespread use.
