摘要
介绍、分析了引进温室灌溉施肥系统的组成和工作原理;测试了灌溉和施肥系统的运行效果;并对温室灌溉施肥系统的选型及配置提出了建议。结果表明:引进的灌溉施肥系统布置合理,从荷兰引进的灌溉施肥系统能达到设定的灌溉施肥水肥混合标准与效果;系统配制营养液时,有较好的调节功能。在灌水器所允许的工作压力范围内,引进系统的田间灌水均匀度较高,内镶式滴灌管为95%,针箭式滴头为91%,系统性能良好。
Irrigation and fertilization system is an important equipment of modern greenhouse. In this paper,the authors discuss the composition and the principle of irrigation andfertilization system inside modern greenhouse and a test for determining the operation effectsof the system. Some opinions on irrigation and fertilization system used in modern greenhouses are also put forward. The test results show that the arrangement of irrigation and fertilization system are reasonable,the system introduced from Holland can achieve the setting valuesof mixed water and fertilizer,and has a good function of adjusting nutrient solutions. Withinthe tolerable operating pressure,the emission uniformity is 95 % for integral dripperline, 91 %for injection type dripper,so the emission uniformity of introduced system is high.
