前言喷灌是一项农田灌溉新技术。近年来,随着种茶科学水平和机械化水平的提高,喷灌在茶叶生产上已开始逐步推广应用,我场从1978年起开展茶园喷灌工作,到1980年已建成固定式茶园喷灌1041亩,占我场现有茶园面积的六分之一,用三个机埠加压供水,其中一座最大的机埠控制980亩茶园的喷灌,成为我省目前茶园固定喷灌规模最大的工程之一。为了充分发挥喷灌投资的效果,将有限的水源灌溉更多的茶园,我们先在50亩丰产茶园中开展了茶树喷灌田间试验,摸索茶树旱季的耗水规律,探索茶树适时喷灌的几项技术指标,分析茶园喷灌制度中各个基本参数,供今后大面积茶园喷灌作参考。
Introduction Sprinkler irrigation is a new technology for irrigation of farmland. In recent years, with the scientific level of tea cultivation and the improvement of mechanization, sprinkler irrigation in the production of tea has begun to promote the gradual application of my field from 1978 to carry out sprinkler irrigation of tea plantations, has been completed in 1980, 1,041 acres of fixed-type tea plantation sprinkler, accounting for One-sixth of the existing area of tea plantation in our field is pressurized with three ports. One of the largest terminals controls the sprinkling of 980 mu of tea plantations, making it one of the largest projects in the province for the fixed sprinkling of tea plantations. In order to give full play to the effect of sprinkler irrigation, we will use limited water sources to irrigate more tea farms. We first conducted field experiments on tea sprinkling in 50 mu of high-yield tea gardens, and explored the water consumption rules of tea trees in dry seasons and explored several technical indicators , Analysis of the basic parameters of sprinkler irrigation system in the tea garden for future large-scale sprinkler irrigation for reference.
