移动喷灌机系统的使用??喷灌泵启动后,通过阀门控制供水压力,使其保持在0.18千帕。喷灌时间一般选在上午或下午,这时进行喷灌后地温能快速上升。喷水时间及间隔可根据蔬菜不同生长期和需水量来确定。随着蔬菜植株的增高,喷灌时间需逐步延长。经测定,在高温季节喷灌20分钟,棚内可降温6~8℃。因喷灌的水直接喷洒在作物叶面上,便于叶面吸收,既防止病虫害,又利于蔬菜生长。??利用移动喷灌机进行施肥??喷灌能够随水施肥,提高肥效。宜施用易溶解的化肥,每次3~4千克。先将化肥溶解后倒入施肥罐内,因施肥罐连通支水管,所以打开施肥阀,调节主水阀,待水管中有水流时即可开始喷,一般1次喷15~20分钟。化肥溶液与水之比可根据蔬菜生长情况而定。喷灌施肥后,继续喷水3~5分钟,以清洗管道与喷头。??五、喷灌的优点??移动喷灌机可根据蔬菜需水量适时供水,保证土壤不板结,从而促进蔬菜生长和延长蔬菜供应期。实践证明,选用质量好的喷灌系统,还可节水50,节肥30,提高作物产量20%。 河北衡水华耀农业设施工程有限公司专业生产销售移动喷灌机，潮汐苗床，移动苗床，苗床网，固定苗床，物流苗床苗床配件，立体种植槽，各种护栏等，期待您的参观考察。 The use of mobile sprinkler system After the sprinkler pump is started, the water supply pressure is by the valve to keep it at 0.18 kPa. Sprinkler irrigation time is usually selected in the morning or afternoon, when the ground temperature can rise rapidly after sprinkler irrigation. The time and interval of spraying water can be determined according to different growth periods and water demand of vegetables. With the increase of vegetable plants, sprinkler irrigation time needs to be gradually prolonged. After measurement, the temperature in the shed can be reduced by 6 ~ 8 ℃ after sprinkling irrigation for 20 minutes in high temperature season. As the sprinkler irrigation water is directly sprayed on the of crops, it is convenient for the to absorb, which not only prevents diseases and insect pests, but also facilitates the growth of vegetables. Using mobile sprinkler to carry out fertilization and sprinkler irrigation can fertilize with water and improve fertilizer efficiency. It is advisable to apply soluble chemical fertilizer, 3 ~ 4kg each time. First, dissolve the chemical fertilizer and pour it into the fertilization tank. Since the fertilization tank is connected with the branch water pipe, the fertilization valve is opened and the main water valve is adjusted. When there is water flow in the water pipe, spraying can be started, usually for 15-20 minutes at a time. The ratio of fertilizer solution to water can be determined according to the growth of vegetables. After sprinkling irrigation and fertilization, continue spraying water for 3-5 minutes to clean pipelines and nozzles. Five, the advantages of sprinkler irrigation mobile sprinkler can timely supply water according to the water demand of vegetables, to ensure that the soil does not harden, thus promoting the growth of vegetables and prolonging the supply period of vegetables. Practice has proved that the selection of sprinkler irrigation system with good quality can also water by 50%, fertilizer by 30% and increase crop yield by 20%.
