    摘要:

    當(dāng)今人類正面臨著全球氣候變暖,、資源短缺,、耕地退化和人口膨脹的巨大挑戰(zhàn),，發(fā)展保護(hù)性耕作有助于解決這些問(wèn)題,，促進(jìn)農(nóng)業(yè)可持續(xù)發(fā)展,。目前已經(jīng)成為南北美洲,、澳洲國(guó)家的主流耕作方法,，歐,、亞,、非洲國(guó)家也在應(yīng)用推廣。我國(guó)保護(hù)性耕作的農(nóng)藝研究早在20世紀(jì)60年代已經(jīng)開(kāi)始,，但機(jī)械化保護(hù)性耕作系統(tǒng)試驗(yàn)相對(duì)較晚,。1991年以來(lái)，研究了大批輕型以及驅(qū)動(dòng)型免耕播種機(jī)具,，通過(guò)農(nóng)藝農(nóng)機(jī)結(jié)合的田間試驗(yàn)形成了一批保護(hù)性耕作技術(shù)模式,，為示范推廣奠定了基礎(chǔ)。

    Abstract:

    Human beings are facing great challenges today on global warming, resources shortage, land degradation and population expansion. The development of CT (conservation tillage) should have big help to reply the challenges and promote sustainable agriculture forward. CT has become the major tillage method in American and Australian continents, also has development in European, Asian and African continents with different levels. The agronomy study of CT in China had started in early 60 last century, but the mechanized CT was started later. From 1991, quite a few of light as well power driven notill planters, together with many CT field technologies have been created, thus,，a sound base for CT demonstration and extension was formed.  
