【二十四節(jié)氣】今日小滿，農(nóng)事活動漸忙

導讀：小滿是夏季的第二個節(jié)氣，是提示農(nóng)事的節(jié)氣。其含義是夏熟作物的籽粒開始灌漿飽滿，但還未成熟，只是小滿，還未大滿。小滿時節(jié)，萬物繁茂，生長旺盛。

　　【農(nóng)機網(wǎng) 熱點關(guān)注】 北京時間5月21日3時37分，二十四節(jié)氣之一的“小滿”節(jié)氣正式到來。小滿是夏季的第二個節(jié)氣，是提示農(nóng)事的節(jié)氣。其含義是夏熟作物的籽粒開始灌漿飽滿，但還未成熟，只是小滿，還未大滿。小滿時節(jié)，萬物繁茂，生長旺盛。
 

 

　　小滿時節(jié)農(nóng)事活動注意事項
 
　　小滿時節(jié)，小春作物即將收獲，中稻全面栽插，農(nóng)事繁忙，晴天搶收，雨天搶栽。但小滿時節(jié)又易出現(xiàn)干旱天氣，“蓄水如蓄糧”，“保水如保糧”，既要注意蓄水防旱，又要注意可能出現(xiàn)的陰雨天氣影響小春收獲。
 
　　此時，農(nóng)事活動也即將進入大忙季節(jié)，夏收作物已經(jīng)成熟，或接近成熟；春播作物生長旺盛；秋收作物播種在即。北方地區(qū)的春播工作已基本結(jié)束，各地要做好春播作物的田間管理，近期出現(xiàn)降雨的地區(qū)要抓住雨后的有利時機，及時查苗、補種，力爭苗全、苗壯；同時注意防御大風和強降溫天氣對春播作物幼苗造成的危害。
 
　　北方冬小麥已進入產(chǎn)量形成的關(guān)鍵階段，應加強后期肥水管理，防止根、葉早衰，促進冬小麥充分灌漿，提高籽粒重；墑情偏差的地區(qū)要適時灌溉，防御高溫、干旱和“干熱風”天氣造成的危害，對可能出現(xiàn)大雨、大風的地區(qū)，在天氣過程來臨前不要澆水，以減少小麥倒伏。
 
　　南方夏收糧油作物產(chǎn)區(qū)要抓住晴好天氣，適時收曬成熟的小麥、油菜，避免不利天氣造成損失。江南、華南地區(qū)在早稻移栽后應注意淺水灌溉、適時施肥，促進早稻早生快發(fā)和多分蘗；對夠苗的田塊要及時排水曬田，控制無效分蘗，并注意做好稻田病蟲害的監(jiān)測與防治工作。
 
　　小麥產(chǎn)區(qū)
 
　　此時宜抓緊麥田蟲害的防治，預防干熱風和突如其來的雷雨大風、冰雹的襲擊。南方宜抓緊水稻的追肥、耘禾，抓緊晴天進行夏熟作物的收打和晾曬。這一時期，一定要注意澆好"麥黃水"，抓緊麥田蟲害的防治，以增強麥子的長勢，同時還應采取一些有效的防風措施預防干熱風和突如其來的雷雨大風的襲擊。
 
　　水稻產(chǎn)區(qū)
 
　　小滿因為"立夏小滿正栽秧"，"秧奔小滿谷奔秋"，小滿正是適宜水稻栽插的季節(jié)。華南的夏旱嚴重與否，和水稻栽插面積的多少，有直接的關(guān)系;而栽插的遲早，又與水稻單產(chǎn)的高低密切相關(guān)。華南中部和西部，常有冬干春旱，大雨來臨又較遲，有些年份要到6月大雨才姍姍而來，最晚甚至可遲至7月。
 
　　加之常年小滿節(jié)氣雨量不多，平均僅40毫米左右，自然降雨量不能滿足栽秧需水量，使得水源缺乏的華南中部夏旱更為嚴重。俗話說："蓄水如蓄糧"，"保水如保糧"。
 
　　為了抗御干旱，除了改進耕作栽培措施和加快植樹造林外，特別需要注意抓好頭年的蓄水保水工作。但是，也要注意可能出現(xiàn)的連續(xù)陰雨天氣，對小春作物收曬的影響。西北高原山地區(qū)，這時多已進入雨季，作物生長旺盛，欣欣向榮。
 
　　小滿到了，“三夏”大忙也不遠了，基于今年春耕生產(chǎn)的順利進行，“三夏”成果更讓人期待，預祝今年夏糧豐收。
 
　　各地“三夏”生產(chǎn)情況本網(wǎng)將陸續(xù)更新，歡迎持續(xù)關(guān)注。
