浙江省粮食生产以水稻为主,水田面积2213.34万亩,占全省总耕地80.5％。随着工农业生产的发展,对水的需求越来越高,因此合理利用水资源的问题就更加显得突出,而水稻的灌溉制度和灌溉定额又是科学用水、计划用水,节约用水的主要依据,我们在水资源调查研究工作中,对连作水稻灌溉定额分片方面,收集了一些资料,做了些补充计算工作,现将初步结果概述如下。
Grain production in Zhejiang Province is dominated by paddy fields, with an area of 22,133,400 mu of paddy fields, accounting for 80.5% of the total cultivated land in the province. With the development of industrial and agricultural production, the demand for water is getting higher and higher, so the problem of rational utilization of water resources becomes even more prominent. The irrigation system of rice and irrigation quotas are the main basis for scientific and planned water use and water conservation. In the work of water resources investigation and research, we collected some information on the quantitative slicing of rice for continuous crop irrigation and did some supplementary calculations. The preliminary results are summarized as follows.
