導讀：這次強降雪降溫天氣將給設施蔬菜生產帶來一定影響，為應對低溫大雪天氣做好設施蔬菜生產，現(xiàn)將有關工作提示如下。

　　【農機網(wǎng) 科技創(chuàng)新】 各市(地)、縣(市、區(qū))農業(yè)農村局：
 
　　據(jù)省氣象臺2024年11月26日11時發(fā)布，26日下午:黑河東部、伊春、綏化北部、鶴崗有大雪，其中伊春東部、鶴崗西部局地有暴雪、大暴雪。26日夜間到27日白天:大興安嶺、黑河北部、伊春中北部、鶴崗、佳木斯中西部、雙鴨山西部、七臺河有暴雪，其中黑河北部、伊春北部、鶴崗局地有大暴雪，黑河南部、伊春南部、齊齊哈爾西部、綏化北部、哈爾濱東北部、佳木斯東部、雙鴨山東部有中到大雪。26日夜間最低氣溫:大興安嶺北部、伊春北部、齊齊哈爾北部、大慶、綏化、佳木斯-15～-13℃，其它地區(qū)-12～-10℃。另外，26日下午至夜間全省大部地區(qū)有6～7級陣風，中東部局地陣風8～9級。這次強降雪降溫天氣將給設施蔬菜生產帶來一定影響，為應對低溫大雪天氣做好設施蔬菜生產，現(xiàn)將有關工作提示如下：
 
　　一要做好棚室加固。加強設施棚室風險排查，對發(fā)現(xiàn)的隱患，該加固的加固、該維修的維修，消除風險隱患。加固墻體和骨架，及時修補或更換破損棚膜、保溫棉被。做好供電線路檢查、卷簾機維護、增溫設施調試、供水系統(tǒng)防凍等檢修維護工作，保證設備運轉正常。
 
　　二要及時清雪除冰。下雪過程要加強值守和巡查，做到隨下隨清，尤其要注意加強夜間清雪工作，避免積雪或冰層過厚壓塌棚室。在清雪除冰過程中，要注意提醒棚內外作業(yè)人員人身安全。
 
　　三要加強棚內保溫。在寒潮降雪天氣來臨前，指導農戶及時關閉放風口，夜間覆蓋保溫被，在棚室四周、后墻和棚腳處增蓋草苫(簾)，防風保溫。必要時可使用加溫設備，還可根據(jù)實際情況在棚室內多層覆膜，降低熱量散失。同時注意安全生產，防止火災和一氧化碳中毒。
 
　　四要加強生產管理。指導農戶做好生產管理，天晴及時揭棉被，連陰天可以在后墻張掛反光幕或增加補光燈增強光照。盡量避免降溫降雪時澆水，造成地溫下降，增加病害發(fā)生風險。適當噴施葉面肥補充養(yǎng)分，減輕低溫生理障礙。做好通風降濕及病害預防，保證地產蔬菜產品穩(wěn)定供應。
 
　　五要加強調度。加強蔬菜生產調度，指導菜農合理安排種植品種和茬口，強化產銷對接服務，提升產銷對接針對性、精準性、有效性。引導蔬菜優(yōu)勢產區(qū)與大中城市加強協(xié)作，建立穩(wěn)定的供銷渠道，支持有條件的大型農產品批發(fā)市場、生鮮電商企業(yè)擴大基地直采，保障市場供給，促進菜農增收。
