摘要
为探讨茶叶的高效节水灌溉制度及灌溉定额,设计4种不同灌溉方式及不同梯度灌溉定额进行田间试验。结果表明:最优灌溉定额为1500 m^3/hm^2;最佳灌溉效率的灌水时期及次数为:春梢期灌水4次,夏梢期灌水3次,秋梢期灌水4次,冬梢期灌水2次,全生育期总灌水13次。
In order to study the efficient and water-saving irrigation system and irrigation quotas of tea,four kinds of irrigation modes and different irrigation quotas were designed for field test.The results of test demonstrated that the optimal irrigation quota was 1500 m^3/hm^2.The optimal irrigation period and times of irrigation efficiency were as follows:4 times of irrigation in spring shoot,3 times of irrigation in summer shoot,4 times of irrigation in autumn shoot,2 times of irrigation in winter shoot,and 13 times of irrigation in the whole growth period.
