微型集雨系统对旱坡地上葡萄产量的影响

Effects of Miniature Rain Collection System on the Grape Yield in Arid Hillside Field

[目的]分析微型集雨系统在旱坡地应用的可行性。[方法]基于阜新地区的降雨概率分析确定微型集雨系统的面积,并估算葡萄产量,研究微型集雨系统对旱坡地葡萄产量的影响。[结果]采用较小的集雨面积可以增加单位面积上葡萄种植的株数,既增加了土地的覆盖面积和使用率,也增加了葡萄产量。不设微型集雨系统的葡萄产量为7079kg/hm2,当微型集雨系统面积为9m2时,估算的葡萄产量为9100kg/hm2,比不设微型集雨系统的增产29%。[结论]微型集雨系统比较适合在干旱半干旱地区应用,最好的葡萄树微型集雨系统面积为9m2。

[Objective] The purpose was to analyze the application feasibility of miniature rain collection system （MRCS） in arid hillside field. [Method] Based on the rainfall probability of Fuxin area, the area of MRCS was analyzed and ascertained and the grape yield was estimated so as to study the effects of MRCS on the grape yield in arid hillside field. [Result] The smaller area of rain collection could increase grape plants planted in unit area. This increased not only coverage area and usage rate of land, but also grape yield. The grape yield without MRCS was 7 079 kg/hm^2. When the area of MRCS was 9 m^2, the estimated grape yield was 9 100 kg/hm^2, increasing 29 % in comparison with that without MRCS. [Conclusion] MRCS was more suitable for arid and semi-arid areas. The best area of MRCS for grape tree was 9 m^2. Key words
