塑料大棚蔬菜膜下滴灌技术是一种节水高产的先进灌水技术。它集水利、农业、生物、物理、化学等多学科于一体，实现塑料大棚蔬菜生产优质高产高效。本文论述了膜下滴灌的灌水量、湿度、地温、气温及抗病虫害等技术要素，并相应地与沟畦灌、无膜滴灌作了对比试验。膜下滴灌较传统沟畦灌、无膜滴灌，节水３０．５％、１０．９％，增产３０．１％、５．９３％。
Plastic greenhouse vegetable drip irrigation technology is a water-saving high-yielding advanced irrigation technology. It sets the water conservancy, agriculture, biology, physics, chemistry and other disciplines in one to achieve high-yield plastic greenhouse vegetable production and high efficiency. In this paper, the technical factors such as irrigation volume, humidity, ground temperature, air temperature and pest and disease resistance of drip irrigation under mulch were discussed, and comparative experiments were carried out with ditch irrigation and drip irrigation without membrane. Drip irrigation than conventional ditch irrigation, membrane-free drip irrigation, saving 30.5%, 10.9%, an increase of 30.1%, 5.93%.
