為此，山東省研究制定了2015年棉花輕簡化生產(chǎn)關(guān)鍵技術(shù)實(shí)施方案。該項(xiàng)目在濱州市無棣縣農(nóng)業(yè)局實(shí)施，項(xiàng)目示范區(qū)5萬畝，輻射帶動(dòng)10萬畝。計(jì)劃要求良種普及率100%，脫絨包衣標(biāo)牌棉種占100%，機(jī)械化耕種率100%，機(jī)械化除草率100%，機(jī)械化病蟲統(tǒng)防統(tǒng)治率100%。通過項(xiàng)目實(shí)施大幅度提高棉花生產(chǎn)的規(guī)?；C(jī)械化、組織化和服務(wù)化水平。力爭實(shí)現(xiàn)比傳統(tǒng)精耕細(xì)作栽培模式減少人工成本1/4-1/5，每畝減少用工4-5個(gè)，物化投入減少10%，畝節(jié)本160-200元。
