導(dǎo)讀:針對我市大豆生產(chǎn),制定夏大豆單產(chǎn)提升技術(shù)指導(dǎo)意見。

  【農(nóng)機(jī)網(wǎng) 熱點關(guān)注】 當(dāng)前,我市正值“三夏”生產(chǎn)關(guān)鍵時期,夏大豆即將搶時播種。為切實抓好大豆播種和田間管理,確保大豆單產(chǎn)明顯提高,針對我市大豆生產(chǎn),制定夏大豆單產(chǎn)提升技術(shù)指導(dǎo)意見。
 
  一、科學(xué)選種,做好種子處理
 
  選擇成熟期適中、高產(chǎn)、適應(yīng)性與抗病性好、稈強(qiáng)抗倒、適合機(jī)械化收獲的高產(chǎn)品種。所選品種應(yīng)通過天津市審定或引種備案,嚴(yán)禁跨區(qū)引種。播前進(jìn)行發(fā)芽率測定,根據(jù)種子發(fā)芽率確定畝播種量,并選用含有精甲霜靈•咯菌腈成分的種衣劑進(jìn)行播前拌種,提高大豆保苗率。
 
  二、適墑播種,提高出苗質(zhì)量
 
  苗齊苗全苗勻苗壯是大豆單產(chǎn)提升的關(guān)鍵。建議雨后趁墑播種,墑情不足時可造墑播種或播后噴灌補(bǔ)墑。一般地塊畝保苗1.2萬~1.5萬株,耐密品種或者晚播可適當(dāng)增加密度。建議使用免耕覆秸精量播種機(jī),一次性完成精量播種、側(cè)深施肥、秸稈覆蓋等作業(yè);也可小麥低茬收割、秸稈粉碎拋撒,趁墑免耕播種。
 
  三、優(yōu)化施肥,推進(jìn)減量增效
 
  合理施用氮磷鉀肥料。補(bǔ)充硼肥和鉬肥,在缺乏癥狀較輕地區(qū),可采取微肥拌種的方式,最好和微生物菌劑混合拌種,提高結(jié)瘤效率。每畝施用復(fù)合肥(15:20:10)12~22公斤,如果底肥施用不足,可在大豆花莢期畝追施尿素5公斤。為增加粒重,提高產(chǎn)量,可在大豆鼓粒期每畝再噴施磷酸二氫鉀200克+硼砂0.5公斤。有條件的地區(qū)可采用滴灌、噴灌等水肥一體化技術(shù)。
 
  四、統(tǒng)防統(tǒng)治,強(qiáng)化綠色防控
 
  播種后及時進(jìn)行封閉除草,也可在大豆2~3片復(fù)葉期進(jìn)行苗后除草。選用含有吡蟲啉、噻蟲嗪以及殺菌劑的種衣劑包衣防治主要病害、苗期刺吸式昆蟲危害。注意防治點蜂緣蝽、灰飛虱、紅蜘蛛、蚜蟲等蟲害,重點防治點蜂緣蝽,預(yù)防“癥青”現(xiàn)象發(fā)生。提倡統(tǒng)防統(tǒng)治,早晨或傍晚點蜂緣蝽活動較遲鈍,防治效果良好。藥劑施用避免重噴、漏噴,防止藥害發(fā)生,提高防除效果。
 
  五、前控后促,加強(qiáng)防災(zāi)減損
 
  大豆苗期適當(dāng)控水,促進(jìn)大豆根系下扎;花莢期如遇干旱天氣,建議灌溉補(bǔ)水,促進(jìn)大豆結(jié)莢和鼓粒。對旺長田塊,在分枝期或初花期用5%的烯效唑可濕性粉劑25~50 克/畝,兌水40~50 公斤噴施莖葉,控制基部節(jié)間伸長,防止倒伏。
 
  六、適時機(jī)收,力促提質(zhì)增效
 
  大豆葉片全部脫落,植株呈現(xiàn)原有品種色澤,籽粒含水量降為16%~18%時可進(jìn)行機(jī)械收獲。含水量過大、過小時均易發(fā)生種子破碎。要避開露水,防止籽粒黏附泥土,導(dǎo)致“泥花臉”,影響外觀品質(zhì)。建議選用大豆專用收割機(jī)或配備大豆專用割臺的收割機(jī)收獲。使用稻麥?zhǔn)崭顧C(jī)收獲時注意調(diào)整撥禾輪轉(zhuǎn)速,減輕對植株的擊打力度,減少落莢、落粒。正確選擇和調(diào)整脫粒滾筒的轉(zhuǎn)速與間隙,降低大豆籽粒的破損率。
