合理的水田灌溉制度,是保障水稻省水高产的一项关键措施。我们在研究水田灌溉制度的同时,对旱种水稻三叶期建立水层和早种不建立水层进行湿润灌溉,作了对比试验。试验区的农业措施、土壤条件都基本一致,试验目的是为探讨省水栽培的效果,和在不同灌溉条件下的用水高峰,从而为发展水田生产提供科学依据。
Reasonable paddy irrigation system is a key measure to ensure high yield of rice water. While studying the paddy field irrigation system, we established the water layer in the three-leaf stage of dry-cultivated rice and did not establish the water layer for wet irrigation in the early stage. We made a comparative experiment. The agricultural measures and soil conditions in the experimental area are basically the same. The purpose of the experiment is to explore the effect of water-saving cultivation and the peak of water use under different irrigation conditions so as to provide a scientific basis for the development of paddy field production.
