今日秋分│金秋九月豐收季,三秋時節農事忙

  【農機網 熱點關注】 今天是二十四節氣之一的秋分節氣,也是秋季的第四個節氣。秋分日后,太陽光直射位置南移,北半球晝短夜長,晝夜溫差加大,氣溫逐日下降。2018年起,國家將每年秋分設立為“中國農民豐收節”,這是在國家層面為農民設立的第一個節日。
 
  秋分前后,由于降溫快,使得秋收、秋耕、秋種的三秋大忙顯得格外緊張。華北地區已開始播種冬麥,長江流域及南部廣大地區正忙著晚稻的收割,搶晴耕翻土地,準備油菜播種。
 
  主要農事活動
 
  晚稻
 
  在冷空氣入侵時,對晚稻采用灌水保溫,灌水二寸以上;低溫來臨時,采取晴天日排夜灌、雨天灌滿水,一般天氣干干濕濕,以濕為主。晚稻抽穗以后,不再長根長葉,營養生長基本停止。根系吸肥吸水功能下降,如果管理不當,就會出現“大穗有余,結實不足,前勁有余,后勁不足”的早衰現象。因此,要防斷水過早。
 

 

  晚稻齊穗以后,隨著氣溫的逐漸下降,根系吸收功能日益衰退,而穗部尚在營養充實階段,需要足夠的營養供應。
 
  播種
 
  收獲玉米后,抓緊深耕、施肥和播前整地3個環節。麥田的耕作整地應做到:深耕深翻,加深耕層;耕透耙透,不漏耕漏耙;土壤細碎,無明暗坷垃;地面平整;上虛下實;蓄水保墑和底墑充足。只有這樣才會為冬小麥高產準備出良好的水、肥、土基礎條件。
 
  棉花
 
  適時分期采摘新棉,堅持“四分四快”,就是分收、分曬、分藏、分售和快收、快曬、快揀、快售,以提高品質。
 
  蔬菜
 
  秋分之時,可以進行菠菜、大蒜、黃芽菜的播種定植,對于秋收蔬菜,要加強管理,延長采收供應期,提高蔬菜的商品品質。
 
  冬小麥
 
  東北、西北地區的冬小麥開始播種,注意要提高小麥的發芽成活率,為小麥高產墊定堅實的基礎。
 
  此外,秋分前后北方已有較強冷空氣侵入,而臺風和熱帶氣旋也不示弱,與之結合,有可能產生暴雨和大暴雨,造成洪澇災害,應注意防范。
