地膜覆盖玉米、红苕同床分层育苗,是根据玉米、红苕发芽的起点温度不同,在同一苗床内,将玉米,红苕种分层放置,用一膜覆盖同时增温育苗,使两种作物达到单一作物盖膜育苗的效果。这是在盖膜育苗的推广过程中,不断试验、摸索,逐步改进为一膜—土同时两用的新技术。从1982年开始试验、示范,到1984年成套试验和推广的生产实践来看,技术效果和经济效果都是很好的。 Mulching of mulching with red mullet and laying of red mulch at the same bed are based on the different starting temperatures of germination of corn and red mulberry. Laying of corn and red mullet in layers in the same seedbed, Effect of a single crop cover film nursery. This is in the process of popularization of the cover film nursery, continuous testing, exploration, and gradually improve for a film - the new technology of soil at the same time. From the beginning of experiment and demonstration in 1982 to the complete set of experiments and promotion of production practice in 1984, the technical effect and economic effect are very good.
