【
農機網 科技創(chuàng)新】日前,云臺分公司接到國家知識產權局通知,該公司研發(fā)的“輕型簡化折疊條帶
播種機”獲得國家新型專利證書,這是該公司秉承創(chuàng)新精神,重視加大對農科技研發(fā),積極探索適合黏土地的高產穩(wěn)產播種技術,實現高效節(jié)本簡化目標取得的重要成果。
云臺分公司地處蘇北,土地鹽堿重,土質差,前幾年麥稻特別是小麥產量低,效益差,從2015年以來,該公司積極研究探索適合公司實際的播種技術,2017年“小麥寬幅精簡播種技術”獲得成功。
這套播種技術投入使用以后,配套冬灌、鎮(zhèn)壓、肥料科學運籌等技術,提高了播種質量,它用種少,效率高,能適應不同墑情作業(yè)要求,達到了“早苗、勻苗、齊苗、壯苗”,通過建立合理群體起點,為實現“足穗、壯稈大穗、增粒增重”高產打下堅實基礎,云臺小麥單產也實現了五年增。
2017年至2021年,云臺分公司畝播量從38.9公斤降到25公斤,畝產量從459公斤提高到672.5公斤,產量增幅達213.5公斤/畝,增產46.5%,與此同時,云臺小麥品質也大幅提升,小麥千粒重49.7克,容重825克。在實現高產、高質、高效的同時,雙減目標也穩(wěn)步推進,僅2021年農藥使用純量較2020年本部下降22%,外拓基地下降16.4%;氮肥用量較2020年本部下降1.2% ,外拓基地下降4.87%。這一播種技術也被譽為“云臺模式”,目前已在周邊農場及黏土地分公司推廣應用面積超50萬畝,取得了明顯的高產穩(wěn)產節(jié)本效果。
