为服务生产自救,湖北省农业厅邀请华中农业大学、湖北省农业科学院有关专家制定了《受涝稻田种子减灾关键技术措施(购种必读)》,供有关市县和种子使用者参考。1.研判稻田灾情,科学确定补救措施中稻拔节前受淹的田块,退水次日有白根产生的,加强肥水管理等措施,以利促弱转壮。中稻拔节后受淹的田块,退水后随机试割几蔸,若次日有新叶抽出的,应优先采用留茬再生,该措施既可节省投入,且产量较高。此措施7月25日前均可进行,宜早不宜迟,时间越迟产量越低,8月15日之后不 For the sake of self-help in service production, Hubei Provincial Department of Agriculture invited Huazhong Agricultural University and Hubei Academy of Agricultural Sciences to develop the “key technical measures for seed-reduction of paddy-flooded paddy fields (for purchase and reading)” for reference of relevant county and seed users. 1. To determine the disaster in paddy fields, determine the scientific recovery of rice in the submerged before the Mid-Okinawa plots, back to the next day white root produce, to strengthen fertilizer and water management measures to facilitate the weak turn strong. Mid-season rice jointed plots after flooding, after rehydration try cutting a few 随, if the next day there are new leaves out, should be given priority to the stubble regeneration, the measure can save investment, and higher yields. This measure can be carried out before July 25, should not be late sooner or later, the later the time the lower the yield, after August 15
