摘要
为提高荔枝产量和质量,节约灌溉水资源,促进农业生产,对荔枝不同生长期的需水量进行了试验研究,结合日耗水强度等因素,讨论了灌水计划湿润层深度、适宜土壤含水量下限、灌水定额、灌水深度等灌溉制度;对荔枝试验田块实施了科学喷灌,达到了预期的目的。
In order to improve the yield and quality of Litchi, and save irrigation water resource, theexperiment of litchi water requirement is studied in each growth phase. The optimal wetness layer depth ,lowerlimit of soil moisture, and irrigation quantity and irrigation depth are discussed. The micro-irrigation isimplemented in experimental plot, and the prospective result is achieved.
