近年来,在治涝方法上,除挖明沟、修台条田等措施外,采用暗排除涝已引起人们的重视。实践证明,暗排可降低和控制地下水位,能克服白浆层和犁底层等“隔水顶板”,增强土壤缓冲旱涝的能力,使水、肥、气、热状况得到协调,从而为农作物高产稳产创造良好的土壤环境。 1990年秋,黑龙江省八五三农场在三分场三、四队推行暗排工程106处,其中塑料暗管21处、杆暗排85处,全长4,120米,成功地解决了15个大小鱼眼泡的内涝,排出了因降水再分配造成的洼地积水与管
In recent years, in the methods of waterlogging control, besides digging the ditch and repairing the table bar and other measures, the use of dark platoon for waterlogging has drawn people’s attention. Practice has proved that the hidden row can reduce and control the groundwater level, to overcome the white pulp layer and plow floor, “baffle,” enhance the ability of soil to buffer drought and water, so that water, fertilizer, gas and heat conditions are coordinated, so as to crops High and stable yield to create a good soil environment. In the autumn of 1990, 835 farms in Heilongjiang Province implemented 106 concealed row projects in the third and fourth teams of the third division, including 21 plastic tubes, 85 dark bars and a total length of 4,120 meters, successfully solving 15 large-sized fish Waterlogging of the eye bubble, discharged due to redistribution caused by precipitation depression water and pipe
