以汝阳县为例,通过剖析两个典型实例,研究并提出了当地旱地农业开发的几个重要方面:(1)改造坡耕地,提高复种指数,增加粮食单产;(2)筑堰打坝,滞洪淤沙,拦泥积肥,调节径流,扩大耕地面积;(3)利用管道灌溉,推行节水技术,减少水量损失,最大限度地发展灌溉面积,(4)合理施肥,调整种植结构,改善土壤营养条件,防止土壤退化,促进地力的良性循环;(5)改革耕作制度,抓好伏深耕和打耱收墒,促进并实现农业高产稳产。
Taking Ruyang County as an example, several typical aspects of dryland agriculture development in the local area are studied and proposed by analyzing two typical examples: (1) rebuilding sloping farmland, raising multiple cropping index and increasing grain yield; (2) (3) Use of pipelines for irrigation, promote water-saving technologies to reduce water loss and maximize the area for irrigation; (4) Rationally fertilize and adjust the planting structure to improve Soil nutrient conditions, to prevent soil degradation and promote a virtuous circle of soil fertility; (5) reform farming system, do a good job V Fu depth farming and harvesting moisture, to promote and achieve high and stable agricultural output.
