对温室而言,高温高湿或低温高湿,都是造成病虫害发生和蔓延的一个重要原因,因此,在温室生产中,应正确选择浇水方法。目前,设施农业最常见的供水技术有沟灌、滴灌、喷灌及毛管带供水技术等。一、沟灌1.配套技术措施沟灌是我国传统的浇水方法。温室内使用沟灌技术需要做好以下工作:(1)平整土地前作物收获后,立即清除残株杂草,消毒土壤,并平整。(2)开挖主水渠道沿着温室长度方向在温室北侧开挖主水渠道,宽60厘米、深度40厘米即可。
For the greenhouse, high temperature and high humidity or low temperature and humidity, are caused by the occurrence and spread of pests and diseases is an important reason, therefore, in the greenhouse production, watering should be the correct choice. At present, the most common water supply technologies in facility agriculture are furrow irrigation, drip irrigation, sprinkler irrigation and capillary tube water supply technology. First, ditch irrigation 1. Supporting technical measures Furrow irrigation is China’s traditional watering methods. The following work needs to be done to use furrow irrigation technology in the greenhouse: (1) Immediately after harvesting the crops, weeds, disinfecting the soil, and leveling the soil should be removed immediately. (2) Excavation of main water channel Along the length of the greenhouse, excavate the main water channel on the north side of the greenhouse with a width of 60 cm and a depth of 40 cm.
