稻茬免耕麦和条播麦是我省两个重点推广项目,也是实现三麦由中产水平(亩产250公斤)向高产水平(亩产300公斤以上)发展和省工节本、提高经济效益的必由途径。近几年有不少地方已经把这两个推广项目有机地结合起来,使免耕、条播两种优势同时发挥,达到了土地生产率和劳动生产率同步提高的目的。根据各地实践的结果:免耕种麦的优势主要表现在能够保证大面积三麦适时播种,变晚茬晚播为晚茬早播;肥力集中在土壤表层,有利于壮苗早发和苗足穗多,同时省工节本,经济效益较高;条播麦则可协调个体发育与群体发展之间的矛盾,麦苗中后期通风透光好,有利于秆壮穗大和防止倒伏,因此免耕机条播麦增产增收显著,深受农民欢迎。
Rice stubble tillage wheat and barley sowing are two key projects in our province, but also to achieve the three wheat from the middle level (250 kg per mu) to the high yield level (300 kg per mu) development and provincial labor costs, improve economic efficiency The only way. In recent years, many localities have organically integrated these two promotion projects so that the two advantages of no-till and birthing can be brought into play at the same time, achieving the goal of simultaneously increasing land productivity and labor productivity. According to the results of local practice: the main advantage of no-till wheat is the ability to ensure timely sowing of large-area three-day wheat and late sowing of late-cropping of late sowing and early sowing; fertility concentrated in the soil surface is conducive to early seedling and seedling Spike more, while the provincial labor costs, higher economic efficiency; barley wheat can coordinate the contradiction between individual development and population development, wheat seedling ventilation and good light in the end, is conducive to strong stalks spike and prevent lodging, so no-tillage machine Sowing wheat yield increased significantly, welcomed by farmers.
