【中國農機網(wǎng) 熱點關注】《中國天文年歷》顯示,今天(11月7日)19時32分,我們將迎來今年冬天的個節(jié)氣——立冬。“立”,即建立、開始;“冬”,古籍《月令七十二候集解》中有言:“冬,終也,萬物收藏也”,意思是說秋季作物全部收曬完畢,收藏入庫,動物也已藏起來準備冬眠。
從這個時候開始,日照時間將持續(xù)縮短,尤其是伴隨著一個超冷空氣的來襲,大半個中國的氣溫將創(chuàng)新低。日前,中國天氣網(wǎng)就推出了秋褲預報,#超兇的冷空氣來了#、#秋褲預警地圖#話題輪番上熱搜。今日,#立冬#、#冬天真的來了#、#不穿秋褲的#、#秋褲安排上#等相關話題更是居高不下。網(wǎng)友們紛紛調侃;“北方的冷,是干冷,那是物理攻擊;南方的冷,是濕冷,那是魔法攻擊。”
與大部分網(wǎng)友們調侃態(tài)度不一樣,立冬的到來對于農民們來說具有獨特意義。這個時候,普遍北方大幅降溫,南方有的地區(qū)仍在搶秋收及搶種晚茬冬麥。這時北方冷空氣常頻頻南侵,有時形成大風、降溫并伴有雨雪的寒潮天氣。劇烈的降溫,特別是冷暖異常的天氣對農業(yè)生產(chǎn)有嚴重的不利影響,注意氣象預報,根據(jù)天氣變化做好農作物寒害、凍害等的防御工作顯得十分重要。
大田作物
一般來說,立冬前后,我國大部分地區(qū)降水顯著減少。東北地區(qū)大地封凍,農林作物進入越冬期;江淮地區(qū)“三秋”已接近尾聲;江南正忙著搶種晚茬冬麥,以保證播種質量力求做到帶蘗越冬,防止年內拔節(jié),并盡量擴大冬種面積,減少空閑田;而華南卻是“立冬種麥正當時”的佳時期。這時節(jié)正是秋收冬種的大好時段,各地充分利用晴好天氣,搞好晚稻的收、曬、晾,保證入庫質量。
水稻需要適時收割中、晚稻,抓緊翻曬進倉,減少陰雨天氣造成不必要的損失;直播油菜盡可能在11月初播種完畢,秧苗期抓好以蚜蟲為主的病蟲害防治工作;大、小麥要選用優(yōu)良品種,提高播種質量,同時要做好早播小麥的田間管理,稻板麥在抓好播前土壤準備的同時,著重抓好精細覆土消滅“三子”(露子、叢子和深子)和稻田化學除草工作;本月為藺草插種適期和田間管理前期,重點要把好插種質量關,促使移栽后盡快發(fā)根,盡早返青、分蘗、確保全苗。播種結束后,立即進行一次質量檢查,查苗、補好浮苗,防止野鴨(鳥)等傷苗;一熟棉田和未拔柴的棉套麥(蒜),及時拔柴或秸稈還田,深耕破垡,每兩年深耕一次,其他冬季空閑田塊及時耕翻曬垡,做好前茬秸稈還田,增施腐熟有機肥培肥土壤。
蔬菜
立冬后要及時做好大棚搭建工作。同時,做好大棚蔬菜管理,白天氣溫高時可在背風口揭膜通氣,晚上要注意做好大棚密封工作。華北及黃淮地區(qū)一定要在日平均氣溫下降到4℃左右,田間土壤夜凍晝消之時,抓緊時機澆好麥、菜及果園的冬水,以補充土壤水分不足,改善田間小氣候環(huán)境,防止“旱助寒威”,減輕和避免凍害的發(fā)生。
江南及華南地區(qū),及時開好田間“豐產(chǎn)溝”,搞好清溝排水,是防止冬季澇漬和冰凍危害的重要措施。江淮地區(qū),做好大棚長季節(jié)栽培、秋延后栽培茄果類蔬菜拉秧工作,及時清潔田園,耕翻土壤,準備下一季種植。
畜牧業(yè)
生豬秋季防疫工作,著重做好補針工作;耕牛加強放牧,吃足草料;在冬季來臨之間,開展一次驅蟲工作。放牧時,盡量讓山羊吃足草料多長膘;長毛兔秋繁工作,未配種的及時配上種;有養(yǎng)鵝習慣的農戶趕緊引進苗鵝飼養(yǎng),飼養(yǎng)70日齡正趕上春節(jié),可賣上好價錢。
農田管理
客家有農諺:“立冬前犁金,立冬后犁銀,立春后犁鐵(指應早翻土)”,農田深耕不但可以增加地力,而且可以把螻蛄等地下害蟲翻到地面上凍死,深耕在秋末冬初進行為宜,一般深耕到9-13厘米,這樣可以破壞粘蟲、麥葉蜂等害蟲的蛹室,改變其方位,阻止羽化或孵化。
【節(jié)氣農事歌】
1、“立冬即將冬天到,田渠棚舍要修牢,秋收秋種忙掃尾,抗災田管掀高潮。”(適用于江淮地區(qū))
2、“立冬節(jié)到麥分蘗,除草要選晴暖天。耕翻整地修渠道,農田建設掀高潮。”(適用于黃淮海地區(qū))
3、“北風往復幾寒涼,疏木搖空半綠黃。大田整地修渠道,農田建設掀高潮。”(適用于江南華南地區(qū))
