基于不同滴灌带铺设模式下湿润锋运移情况的研究
Research on the Transport of Wetting Fronts under Different Drip Irrigation Tapes Laying Modes
摘要
Abstract
In order to study the variation of horizontal and vertical wetting radii at the beginning and end of drip irrigation tapes under different drip irrigation tapes laying modes with the passage of irrigation time,and to determine the optimal time for cotton drip irriga-tion,this research selected two drip irrigation tapes laying modes to study the movement of soil wetting fronts at the beginning and end of drip irrigation tapes within 2,4,6 and 8 hours after the start of irrigation.The results showed that the time required for the wetting fronts to reach the vicinity of the root system in the one film two tapes and one film three tapes laying modes was 8 and 6 hours,re-spectively.The transport rate of the wetting fronts at the beginning was faster than that at the end,and the transport rate of the wetting fronts in the one film three tapes was faster than that in the one film two tapes laying mode.When the irrigation amount of the two modes was similar,the one film three tapes mode was more time-saving.Compared to the one film two tapes mode,the shape of the wetting fronts at the beginning and end of the one film three tapes mode was more similar,and the time required to meet the root sys-tem requirements was similar.Considering the local conditions,it is recommended to use a one film three tapes laying mode and a 6-8 h irrigation duration for cotton drip irrigation.关键词
