(Chuncheon=Yonhap News) Reporter Yang Ji-woong = The Gangwon Special Self-Governing Province Agricultural Technology Institute urged the pre-management of crops and agricultural facilities due to the forecast of an extremely severe cold wave in inland and mountainous areas of Gangwon Province until next month 1st. Damaged parts of the plastic greenhouses should be promptly repaired to prevent wind damage and heat loss, and care should be taken in opening and closing the windows to prevent fog from forming inside the facility due to diurnal temperature variation, thus preventing growth retardation and physiological damage. Old facilities should have reinforcement supports installed, loose bands of the houses should be pulled tight, and electrical facilities should be checked in preparation for heater breakdowns and power outages. In addition, for each crop, the appropriate temperature should be managed, keeping the minimum night temperature above 12 degrees Celsius for fruit vegetables and above 8 degrees Celsius for leafy vegetables, and ventilation should be maintained to keep the appropriate humidity. For fruit trees such as apples, white water-based paint for fruit trees should be applied to the tree trunks or straw should be wrapped around them to a height of about 1 meter to prevent frost damage. Irrigation facilities should have all the water completely drained due to the concern of freezing. Deputy Director Yu Taek-geun of the Technology Dissemination Division urged on the 30th, "Given the special cold wave warning, there is concern about cold damage to greenhouses, ginseng facilities, and open-field fruit trees, so please check whether the heating facilities are working normally and carry out damage prevention work in advance." yangdoo@yna.co.kr
