喷灌技术在烟草生产上的应用,为改革传统的烟田灌溉方法,提供了有利条件.1978年国家科委在郏县建立了烟草喷灌试点,对烟草喷灌的经济效益及其喷灌制度进行了试验研究,开创了烟草喷灌试验的先例.一、烟草喷灌的经济效益试验研究表明,烟草喷灌具有明显的增产省水效果.以1978年为例,沟灌试区烟草大田生育期每亩灌水334立方米,喷灌试区烟草大田生育期每亩喷水139立方米,比沟
The application of sprinkler irrigation technology in tobacco production provided favorable conditions for the reform of traditional irrigation methods in tobacco fields. In 1978, the State Science and Technology Commission established a tobacco sprinkler irrigation pilot project in Yixian County to test the economic benefits of tobacco sprinkler irrigation and its sprinkling irrigation system Research and create a precedent for tobacco sprinkler test.First, the economic benefits of tobacco sprinkler test studies have shown that tobacco sprinkler irrigation has obvious effects of increasing water yield.With 1978 as an example, furrow irrigation test area per mu irrigation period 334 cubic meters , Sprinkler irrigation test area of ?? tobacco per acre 139 cubic meters of water than ditch
