【今日立夏】夏日初長(zhǎng)，綠肥紅瘦│農(nóng)作物進(jìn)入生長(zhǎng)旺季

2022-05-05 10:14:14 來(lái)源：農(nóng)機(jī)網(wǎng)整理發(fā)布 閱讀量：29749 評(píng)論

導(dǎo)讀：今天是立夏節(jié)氣，是二十四節(jié)氣中的第7個(gè)節(jié)氣，也是夏季的第一個(gè)節(jié)氣。立夏表示告別春天，是夏天的開始，是標(biāo)示萬(wàn)物進(jìn)入旺季生長(zhǎng)的一個(gè)重要節(jié)氣。

　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】 今天是立夏節(jié)氣，是二十四節(jié)氣中的第7個(gè)節(jié)氣，也是夏季的第一個(gè)節(jié)氣。立夏表示告別春天，是夏天的開始，是標(biāo)示萬(wàn)物進(jìn)入旺季生長(zhǎng)的一個(gè)重要節(jié)氣。
 
　　立夏以后，正式進(jìn)入雨季，雨量和雨日均明顯增多。夏季是許多農(nóng)作物旺盛生長(zhǎng)的最好季節(jié)，充足的光照和適宜的溫度以及充沛的雨水給植物提供了所需的條件。 由于我國(guó)幅員遼闊、南北跨度大，各地節(jié)律不一。“立夏”前后，中國(guó)只有福州到南嶺一線以南地區(qū)可能進(jìn)入夏季，而其余大部分地區(qū)還處在春季，在東北和西北的一些地區(qū)，這時(shí)候甚至才剛剛進(jìn)入春季。
 
　　進(jìn)入立夏節(jié)氣以后，在長(zhǎng)江中下游和華南，5月中旬的雨量迅速增大，而此時(shí)的華南，也進(jìn)入了前汛期的盛期，此時(shí)的暴雨往往具有時(shí)間上的連續(xù)性、地域上的廣闊性和強(qiáng)度上的猛烈性特點(diǎn)，在兩廣的珠江水系和福建的閩江水系，年最高水位往往出現(xiàn)在這一時(shí)段，民間有"立夏、小滿，江滿、河滿"的說(shuō)法。立夏時(shí)節(jié)，全國(guó)大部分地區(qū)平均氣溫在18—20℃上下。這時(shí)華北、西北等地氣溫雖然回升很快，但降水仍然不多，加上春季多風(fēng)，蒸發(fā)比較強(qiáng)烈，天氣十分干燥。
 
　　立夏前后，水稻栽插及其他春播作物的管理進(jìn)入大忙季。中稻播種要抓緊掃尾，冬小麥揚(yáng)花灌漿，油菜接近成熟，夏收作物年景基本定局。
 
　　水稻管理：加強(qiáng)水稻田的水肥管理，對(duì)未夠苗的早稻，田間要保持淺水層，并適時(shí)施肥，促進(jìn)其生長(zhǎng)，提高有效分蘗數(shù)；對(duì)已夠苗的早稻要及時(shí)排水露、曬田，控制無(wú)效分蘗。
 
　　小麥管理：應(yīng)根據(jù)田塊的墑情，適時(shí)對(duì)小麥田進(jìn)行灌水。另外，由于立夏后地溫逐漸攀升，田間的雜草會(huì)迅速瘋長(zhǎng)，因此，還要抓緊時(shí)間進(jìn)行除草。
 

 

　　蔬菜管理：蔬菜作物要加強(qiáng)田間管理，適時(shí)施肥、除草和松土，以利生長(zhǎng)。
 
　　果樹管理：做好?；ū９突ê蟛∠x害防治，及時(shí)施足采前肥，適時(shí)采摘，夏季要及時(shí)進(jìn)行疏果、套袋和追肥等工作。
 
　　畜牧管理：氣溫升高時(shí)要注意畜禽舍的降溫通風(fēng)，強(qiáng)化定期消毒，加強(qiáng)蚊蠅滅除，做好疾病預(yù)防和控制工作。
