温室生产快速发展的同时也面临着高效管理利用水资源的问题。千晶晶(2012年)指出,中国水资源短缺,人均占有量少,是世界上最缺水的13个国家之一,农业用水效率低,灌溉用水有效利用系数仅为0.45左右,而发达国家是我们的1.55倍。温室作为农业生产的重要方式,由于自然降雨无法利用,自然消耗水量较大,提高水肥利用是解决这一办法的重要途径。现有苗床灌溉装置多为悬吊式,由悬吊架、悬吊导轨、主行走机构、喷灌装置、随动行走机构和电控系统等部件组成,多用于温室或塑料大棚育苗的灌溉。传统方式的整套喷灌系统结构较为复杂,首先要有纵向的导轨,
The rapid development of greenhouse production also faces the issue of efficient management and utilization of water resources. Chifengjing (2012) pointed out that China has one of the 13 countries with the most water shortages due to its shortage of water resources and per capita possession. The efficiency of agricultural water use is low, and the effective utilization coefficient of irrigation water is only about 0.45, while in developed countries, Our 1.55 times. As an important method of agricultural production, greenhouse as a natural rainfall can not be used, natural water consumption is larger, improve water and fertilizer utilization is an important way to solve this approach. The existing seedbed irrigation device is mostly hanging type, which is composed of suspension frame, suspension guide rail, main running mechanism, sprinkler irrigation device, follow-up running mechanism and electric control system and other components. It is mostly used for irrigating seedlings in greenhouse or plastic greenhouse. The traditional way of sprinkler irrigation system structure is more complex, first of all have vertical rails,
