全膜双垄沟播一膜两茬栽培技术

摘要：为了实现节本增效，在灵台县采用了一膜两年用免耕栽培的方法，开展了全膜双垄沟播玉米收获后穴播冬油菜的生产模式研究，即在玉米成熟后，采用人工收获，清除玉米秸秆，保护好上茬地膜，在原地膜上穴播点种冬油菜，冬油菜产量可达3 080 kg/hm2，是一种轻简方便，高产高效的模式。

Abstract： To achieve input saving and efficiency improvement， cultivation techniques of one film two-crop with no tillage were applied using hole seeding of winter rape after the harvest of maize using full-film double-ridge planting， i.e.， mannual harvestin maize and clearing maize stalk to protect the film used in maize cultivation and hole seeding of winter rape on the exact film used by previous crop. This technique could achieve ayield of 3 080 kg/ha for winter rape and was regarded as a convenient mode with high yield and high efficiency.

Key words： Full-film double-ridge planted maize; Winter rape; One film two-crop
