稻田耕作制度经过不断的发展，形成了菜—麦—稻三熟模式，在此基础上，科技人员经过几年的不断探索，研究成功的菜—玉—稻三熟高效优化模式，比原模式（菜—麦—稻）亩平均增收１２００元。此高效模式增收优势显著。其优势主要表现为：一是早春玉米２月中旬移栽定植，可延长
After continuous development of paddy field farming system, a vegetable-wheat-rice tri-crop pattern has been formed. On this basis, after several years of continuous exploration, scientists and technicians have studied the successful high-efficiency optimization pattern of rice-jade-rice hybrid system, (Vegetables - wheat - rice) mu an average increase of 1,200 yuan. This efficient model has significant advantages. Its main advantages are as follows: First, early spring corn transplanting planting in mid-February can be extended
