今日雨水│春雨貴如油 春耕備耕正當(dāng)時(shí)

2025-02-18 14:03:30 來(lái)源：農(nóng)機(jī)網(wǎng)整理發(fā)布 閱讀量：20075 評(píng)論

　　【農(nóng)機(jī)網(wǎng) 熱點(diǎn)關(guān)注】 雨水，是二十四節(jié)氣之第2個(gè)節(jié)氣。雨水節(jié)氣的含義是降雨開始，降雨量極多以小雨或毛毛細(xì)雨為主，適宜的降水對(duì)農(nóng)作物的生長(zhǎng)很重要。進(jìn)入雨水節(jié)氣，中國(guó)北方地區(qū)尚未有春天氣息，南方大多數(shù)地方則是春意盎然，一幅早春的景象。
 
　　雨水節(jié)氣不僅標(biāo)志著降水增多更意味著農(nóng)事活動(dòng)進(jìn)入關(guān)鍵階段。抓好春耕備耕，是確保全年糧食和重要農(nóng)產(chǎn)品穩(wěn)產(chǎn)保供的關(guān)鍵。農(nóng)時(shí)不等人，此時(shí)，農(nóng)人要抓緊時(shí)間進(jìn)行春耕、施肥、澆灌等工作，以免耽誤農(nóng)時(shí)，影響收成。
 
　　北方冬季漫長(zhǎng)寒冷，土壤水分蒸發(fā)量大，農(nóng)作物急需水分滋養(yǎng)。雨水時(shí)節(jié)，氣溫逐漸上升，小麥管理進(jìn)入關(guān)鍵時(shí)期，是小麥返青、起身期。這個(gè)時(shí)期，小麥的管理要早抓早管，分類指導(dǎo)、合理運(yùn)用水肥。
 
　　南方雨水充沛，為早稻育秧、蔬菜播種創(chuàng)造了絕佳條件。水稻喜水，充足水分是其發(fā)芽、生長(zhǎng)的基礎(chǔ)。各類蔬菜在雨水潤(rùn)澤下，種子能更快發(fā)芽破土。
 
　　雨水節(jié)氣是播種葉類蔬菜的好時(shí)機(jī)。菠菜、生菜、小白菜等被播撒進(jìn)肥沃土地。播種后，及時(shí)澆水、覆蓋地膜，保持土壤濕度、提高地溫，促進(jìn)種子快速發(fā)芽。
 
　　大棚蔬菜注意晝夜溫差，白天適時(shí)通風(fēng)降濕，夜間加蓋保溫材料，預(yù)防霜凍。此外趁晴好天氣整修農(nóng)田水利，清理溝渠，為春灌做好準(zhǔn)備。同時(shí)，蘋果、梨等落葉果樹進(jìn)入修剪尾聲，剪除病弱枝，減少病蟲害滋生；葡萄園及時(shí)綁蔓上架。
 
　　對(duì)于茶園，掌握好早生種茶園開采適期，當(dāng)茶樹蓬面每平方米有10—15個(gè)茶芽符合鮮葉質(zhì)量要求時(shí)，即可進(jìn)行開采。在采摘中要按標(biāo)準(zhǔn)、及時(shí)、分批、勤采，能采就采，應(yīng)采盡采，多采嫩茶。
 
　　愿每一滴春雨都能滋潤(rùn)大地，每一次辛勤的耕耘都能換來(lái)豐碩的果實(shí)。
