摘要
节水灌溉是以浇灌最少量的水得到最大经济效益的作物产量为目标,向农田人工补水的一种技术措施。除了满足作物需水要求外,灌溉还有调节土壤的温热状况、培肥地力、改善土壤深化性状等作用。在四川攀枝花市特定的自然气候条件下,采用滴灌和沟灌两种灌溉方法,对苦瓜和番茄进行灌溉对比实验研究。研究结果表明:滴灌较传统沟灌不仅能节约50%以上的灌水量,降低生产成本,而且可大幅度增加蔬菜产量,提高产品的商品性,减少环境和产品污染。
The experimental researches are carried through drip irrigation and furrow irrigation on balsam pear and tomato productions, in the specific weather conditions of Panzhihua city. They shows that comparing with furrow irrigation, drip irrigation not only reduce water consumption by more than 50% and lower production costs, but also increase the yields enormously, improve the qualities of products and lessen pollutions on environment and products.
