【正文】 保全苗和因根系分布淺而易倒伏等技術(shù)難題導(dǎo)致的直播栽培產(chǎn)量不穩(wěn)的問題還沒有完全解決,將免耕技術(shù)與直播技術(shù)結(jié)合一起,形成免耕直播栽培技術(shù),可以發(fā)揮兩種栽培技術(shù)的優(yōu)勢,克服兩種技術(shù)的不足,有利于提高水稻的產(chǎn)量和穩(wěn)產(chǎn)性。而且更可節(jié)省用工和減輕勞動(dòng)強(qiáng)度,滿足水稻規(guī)模化生產(chǎn)和農(nóng)村青壯勞力外出務(wù)工增多的發(fā)展帶來的對(duì)省工栽培的技術(shù)需求 [14]。 江西是一個(gè)水稻主產(chǎn)省,隨著生產(chǎn)規(guī)?;c勞動(dòng)力的轉(zhuǎn)移,水稻生產(chǎn)的季節(jié)與勞力的矛盾日益凸現(xiàn),特別是南昌作為省會(huì)城市,勞動(dòng)力成本更高,因此,省工的輕簡化栽培技術(shù)更受歡迎,目前, 全省免少耕栽 6 培技術(shù)每年示范推廣在 500 萬畝以上,水稻直播栽培技術(shù)在 300 萬畝左右,而南昌市的水稻免少耕栽培技術(shù)每年示范推廣約 100 萬畝、直播栽培技術(shù)約 80 萬畝,而且有進(jìn)一步擴(kuò)大的趨勢,因此,水稻免直播將是水稻生產(chǎn)的一種發(fā)展趨勢,有廣闊的應(yīng)用前景。 主要參考文獻(xiàn): [1] Pandey S, Velaseo C, Economics of direct seeding in Asia: Patterns of adoption and research priorities[J].
