摘要
为了筛选适宜曲周县后老营村农业生产的较优种植体系并设计更好的种植体系,采用随机抽样调查的方法,对该村主要作物的种植体系及其水肥资源利用状况和经济效益进行了详细调查。结果表明:棉花-西瓜套作体系的水肥资源利用率最高,小麦-西瓜-玉米间套作体系的经济效益最好,棉花-西瓜套作体系次之,二者差异不显著。未来可以基于这2种种植体系重新设计新的种植体系,从而在生态、经济、环境等方面取得较好的综合效益。
In order to screen and design the better planting system suitable for agricultural production in Laoying Village of Quzhou County, the planting system of main crops and the utilization of water and fertilizer resources and economic benefits in the village were detailedly investigated adopting the method of random sampling survey.The results showed that the planting system with highest water and fertilizer resources utilization was cotton-watermelon interplanting system, and the planting system with best economic benefits was the wheat-watermelon-corn intercropping system, followed by cotton-watermelon interplant system, but no significant difference was found between this two plant system.In the future, basing on the two planting system, the new planting system could be designed to achieve comprehensive benefits in ecology, economy, environment and so on.
