为提高规模种粮经济效益,进一步探讨水稻全程机械化高产栽培模式,2015年在衡阳县西渡镇梅花、青木村建立双季稻全程机械化种植高产示范片150 hm~2,采用早稻早中熟品种+拱棚旱育机插秧+小苗(3~3.5叶)机插+配方施肥+间歇灌溉+病虫害专业化防治+机收+机烘,晚稻中熟品种+硬(软)盘泥浆集中育机插秧(4~4.5叶)+机插+配方施肥+间歇灌溉+病虫害专业防治+机收+机烘模式技术。经测产验收,平均产量早稻8278.5 kg/hm~2,晚稻9415.5 kg/hm~2,比常规栽培(水育秧手插秧)分别增产15.36%、22.89%,双季稻增收7600.9元/hm~2,节支6150元/hm~2,达到了粮食增产、增效的目的。
In order to improve the economic efficiency of large-scale grain-growing and further explore mechanization and high-yield cultivation mode of rice, in 2015, 150 hm ~ 2 mechanized high-yielding demonstration crop of double cropping rice was established in Plum and Aoki villages, Xidu Town, Hengyang County. + Arch Nursery plant transplanting + seedlings (3 ~ 3.5 leaves) machine inserted + formula fertilization + intermittent irrigation + pest and disease specialization + machine income + machine baking, late rice medium maturing varieties + hard (soft) 4 ~ 4.5 leaves) + machine inserted + formula fertilizer + intermittent irrigation + pest control + machine + machine baking mode technology. The average yield of early rice 8278.5 kg / hm ~ 2 and late rice 9415.5 kg / hm ~ 2 increased by 15.36% and 22.89%, respectively, and the double crop increased by 7600.9 yuan / hm ~ 2 compared with that of conventional cultivation , Saving 6150 yuan / hm ~ 2, reaching the goal of increasing grain yield and increasing efficiency.
