　　【農(nóng)機(jī)網(wǎng) 熱點(diǎn)關(guān)注】 今日(6月21日)，我們迎來(lái)二十四節(jié)氣中的第十個(gè)節(jié)氣——夏至。此時(shí)節(jié)，嫩荷初綻，萬(wàn)物繁茂，伴隨著似火驕陽(yáng)，在蛙鳴蟬吟中，盛夏正式拉開序幕。
 
　　夏至前后，淮河以南早稻抽穗揚(yáng)花，田間水分管理上要足水抽穗，濕潤(rùn)灌漿，干干濕濕，既滿足水稻結(jié)實(shí)對(duì)水分的需要，又能透氣養(yǎng)根，保證活熟到老，提高籽粒重。同時(shí)，夏播工作要抓緊掃尾，已播的要加強(qiáng)管理，力爭(zhēng)全苗。出苗后應(yīng)及時(shí)間苗定苗，移栽補(bǔ)缺。夏至?xí)r節(jié)各種農(nóng)田雜草和莊稼一樣生長(zhǎng)很快，不僅與作物爭(zhēng)水爭(zhēng)肥爭(zhēng)陽(yáng)光，而且是多種病菌和害蟲的寄主，因此，抓緊中耕鋤地是夏至?xí)r節(jié)極重要的增產(chǎn)措施之一。

　　過(guò)了夏至，中國(guó)南方大部分地區(qū)農(nóng)業(yè)生產(chǎn)因農(nóng)作物生長(zhǎng)旺盛，雜草、病蟲迅速滋長(zhǎng)蔓延而進(jìn)入田間管理時(shí)期，高原牧區(qū)則開始了草肥畜旺的黃金季節(jié)。這時(shí)，華南西部雨水量顯著增加，使入春以來(lái)華南雨量東多西少的分布形勢(shì)，逐漸轉(zhuǎn)變?yōu)槲鞫鄸|少。如有夏旱，一般這時(shí)可望解除。
 
　　夏至前，北方小麥機(jī)收任務(wù)已基本完成。據(jù)農(nóng)業(yè)農(nóng)村部消息，截至6月18日，西南、黃淮海等麥?zhǔn)罩攸c(diǎn)地區(qū)收獲基本完成，新疆、甘肅等西北地區(qū)小麥機(jī)收仍在進(jìn)行，全國(guó)夏糧小麥?zhǔn)斋@進(jìn)度已達(dá)96%。據(jù)悉，今年“三夏”各地共計(jì)投入聯(lián)合收割機(jī)60多萬(wàn)臺(tái)，隨小麥梯次成熟，引導(dǎo)跨區(qū)作業(yè)機(jī)具自南向北有序轉(zhuǎn)移。麥?zhǔn)崭叻迤谟?天單日投入聯(lián)合收割機(jī)在20萬(wàn)臺(tái)以上、最多達(dá)25萬(wàn)臺(tái)，小麥機(jī)收占比超過(guò)98%。更多高效低損收獲機(jī)具投入生產(chǎn)一線，9—10公斤/秒大喂入量聯(lián)合收割機(jī)已經(jīng)成為跨區(qū)作業(yè)主流機(jī)型，進(jìn)一步提升了機(jī)收效率，基本做到成熟一片、收獲一片，沒有出現(xiàn)“糧等機(jī)”的情況。全國(guó)連續(xù)16天日機(jī)收面積維持在1000萬(wàn)畝以上，麥?zhǔn)账俣瘸掷m(xù)高峰推進(jìn)，機(jī)收進(jìn)度同比常年快2—3天，黃淮海重點(diǎn)省份集中機(jī)收結(jié)束時(shí)間均比常年快5天左右。在此期間，局部受降雨影響地區(qū)組織開展雨前搶收，做到適收快收，為后續(xù)搶抓有利墑情開展機(jī)播作業(yè)爭(zhēng)取充足時(shí)間。
