干旱是吕梁市发展农业生产的主要瓶颈,全膜多垄沟播技术是在田间用畜力、人力、机械牵引开沟器开沟起等行距的垄,垄高10 cm,垄宽60 cm,采用2 m地膜全覆盖,在沟内播种作物的种植技术,具有保墒、提墒、集雨、抑蒸、增温、除草、增产的全新抗旱丰产作用,适宜在半干旱区和半湿润偏旱区、旱塬区的垣地、梯田地进行粮、棉、菜、油料等作物单作、间作及瓜菜两茬种植,使无效降雨变有效雨,旱年夺丰产。
Drought is the main bottleneck in the development of agricultural production in Lvliang City. The full-film multi-ridge furrow sowing technique is a ridge with a row width of 10 cm and a ridge width of 60 cm in the field with ditching, manpower and mechanical pulling openers. m full coverage of mulching, sowing crops in the trench cultivation techniques, with moisture, raise moisture, rain, steaming, warming, weeding, increased production of new drought-yielding effect, suitable for semi-arid and semi-humid arid areas, In dryland area, farmland, rice fields, vegetables, oil crops and other crops, intercropping and cucumber crop two crops, so that effective rainfall becomes effective rain, dry seasons for high yield.
