　　【農(nóng)機網(wǎng) 熱點關注】 今天是二十四節(jié)氣之一的小寒，是冬季的第五個節(jié)氣。此時天氣寒冷，大冷還未到達極點，所以稱為小寒。小寒正值“三九”前后，標志著開始進入一年中最寒冷的日子。這個時候?qū)τ谵r(nóng)戶們來說是非常關鍵的，農(nóng)事活動也是管理的重要時期。
 
　　由于中國南北地域跨度大，所以，同樣的小寒節(jié)氣，不同地域會有不同的生產(chǎn)農(nóng)事。在北方，大部分地區(qū)田間已經(jīng)沒有太多的農(nóng)活，都進行歇冬，主要任務是在家做好菜窖、畜舍保暖，造肥積肥等工作。而在南方地區(qū)則要注意給小麥、油菜等作物追施冬肥，海南和華南大部分地區(qū)則主要是做好防寒防凍、積肥造肥和興修水利等工作。小寒、大寒是一年中雨水最少的時段。
 
　　蔬菜管理
 
　　1、小寒時節(jié)，南方地區(qū)要注意給小麥油菜等作物追施冬肥，做好防寒防凍、積肥造肥和興修水利等工作。在冬前澆好凍水、施足冬肥、培土壅根的基礎上，寒冬季節(jié)采用人工覆蓋法也是防御農(nóng)林作物凍害的重要措施。
 
　　2、當寒潮或強冷空氣到來之時，露地栽培的蔬菜地可用作物秸桿、稻草等稀疏地撒在菜畦上作為冬季長期覆蓋物，既不影響光照，又可減小菜株間的風速，阻檔地面熱量散失，起到保溫防凍的效果。遇到低溫來臨再加厚覆蓋物作臨時性覆蓋。
 
　　3、大棚蔬菜以防災害性天氣為主。采取多層覆蓋以保溫，降溫幅度大時可用醫(yī)用維生素B1、B6。酰胺青霉素以藥劑噴灑植株防凍，茄果類防“三落”，這時要盡量多照陽光，即使有雨雪低溫天氣，棚外草簾等覆蓋物也不可連續(xù)多日不揭，以免影響植株正常的光合作用，造成營養(yǎng)缺乏，天晴揭簾時導致植株萎蔫死亡。
 

 

　　畜牧管理
 
　　1、豬舍、牛舍、羊欄要關閉門窗，提高舍內(nèi)溫度。牛羊外出放牧應遲出早歸，做好通風消毒等工作。
 
　　2、飼養(yǎng)蛋雞專業(yè)戶，為提高產(chǎn)蛋率，在飲水中加入適量紅糖，補充冬季寒冷引起的能量不足，增加人工光照。
 
　　果樹管理
 
　　1、繼續(xù)做好冬季清園，剪除病蟲枝，噴布45%晶體石硫合劑或松堿合劑，殺滅越冬病蟲害。
 
　　2、整形修剪：幼年樹以整形為主，成年樹以修剪為主。
 
　　3、做好根部培土，樹干涂白等防凍措施，出現(xiàn)旱情的適度灌水。
 
　　4、修整園地道路及灌排溝渠
 
　　冬小麥
 
　　在黃河地區(qū)，防止冬小麥受凍采取碾壓麥田的方式，除此之外還要為麥田增加，一些稀糞，這時是農(nóng)作物吸收養(yǎng)分的好時節(jié)。
 
　　油菜
 
　　在冬前澆好凍水、施足冬肥、培土壅根的基礎上，寒冬季節(jié)采用人工覆蓋法也是防御農(nóng)林作物凍害的重要措施。當寒潮成強冷空氣到來之時，潑澆稀糞水，撒施草木灰，可有效地減輕低溫對油菜的危害。
 
　　高山茶園
 
　　尤其是西北向易受寒風侵襲的茶園，要以稻草、雜草或塑料薄膜遮蓋篷面，以防止風抽而引起枯梢和沙暴對葉片的直接傷害。
