水稻是我国三大粮食作物之一,在保障我国粮食安全、实现农业增产增收方面发挥着重要作用。但是近年来我国农业用地不断减少,可供灌溉水资源分配日益紧张,一定程度上制约了我国水稻的产量和质量。在这一严峻形势下,革新现有浇灌技术,实现水稻节水灌溉具有极其重要的现实意义。文章以我国南方某地水稻种植区作为实验对象,分析了不同灌水定额对膜下滴灌水稻的影响作用,并综合实验数据测定了水稻的最佳灌水定额。
Rice is one of the three major grain crops in our country and plays an important role in ensuring food security in our country and increasing agricultural output and income. However, in recent years, the agricultural land in China has been continuously reduced, and the allocation of irrigation water resources has become more and more tense. To some extent, this has restricted the output and quality of rice in China. Under this severe situation, it is of extremely important practical significance to reform existing irrigation technologies and realize water-saving irrigation of rice. In this paper, a rice growing area in a certain area of southern China was used as an experimental object to analyze the effect of different irrigation quotas on drip irrigation under film and the optimal irrigation quota of rice was determined by comprehensive experimental data.
