从“天衣无缝”甚至(zhi)“刀耕(geng)火种”到“全方位、全过程机械(xie)化”，中(zhong)国农(nong)业机械(xie)化不断发展，走上了中(zhong)国特色的道路(lu)。

1949年至(zhi)1980年，中央(yang)提出了明确的(de)农(nong)业机(ji)械化发(fa)(fa)展目标和(he)相应的(de)方针(zhen)政策。在(zai)有条件(jian)的(de)社会和(he)队伍中设立(li)农(nong)机(ji)站，支持群(qun)众性农(nong)具改革运动(dong)。我国农(nong)机(ji)产(chan)业从制造新(xin)型农(nong)机(ji)工具起步，从无(wu)到有逐步发(fa)(fa)展。

1981年至1995年，农(nong)(nong)(nong)村(cun)实行(xing)(xing)家庭联产(chan)承包责任(ren)制。集体农(nong)(nong)(nong)机(ji)(ji)站逐(zhu)步(bu)解散。国家开始允(yun)许农(nong)(nong)(nong)民独立(li)购买(mai)和经营农(nong)(nong)(nong)机(ji)(ji)农(nong)(nong)(nong)民逐(zhu)渐成为农(nong)(nong)(nong)业机(ji)(ji)械(xie)(xie)投资经营的(de)主(zhu)体为适应农(nong)(nong)(nong)业生(sheng)产(chan)组(zu)织的(de)重大(da)变化，农(nong)(nong)(nong)机(ji)(ji)行(xing)(xing)业开始了第一轮大(da)规(gui)模结构调(diao)整，重点(dian)生(sheng)产(chan)小型农(nong)(nong)(nong)机(ji)(ji)、手(shou)扶拖(tuo)拉机(ji)(ji)、农(nong)(nong)(nong)副产(chan)品(pin)加(jia)工机(ji)(ji)械(xie)(xie)、农(nong)(nong)(nong)用运输车等。大(da)中型拖(tuo)拉机(ji)(ji)和配套(tao)农(nong)(nong)(nong)具停滞(zhi)不前(qian)，机(ji)(ji)械(xie)(xie)配套(tao)比例失调(diao)，田间机(ji)(ji)械(xie)(xie)利用率低，农(nong)(nong)(nong)业作(zuo)业机(ji)(ji)械(xie)(xie)化水平缓慢提(ti)高。

到20世纪90年代中期，大量农(nong)(nong)村劳动力(li)开(kai)始转移，农(nong)(nong)村季节性(xing)用(yong)工(gong)荒的趋势不断出现国家有关部委开(kai)始组织开(kai)展大规(gui)模跨区域小(xiao)麦收(shou)获(huo)服务大大提(ti)高(gao)了联(lian)合(he)收(shou)割机的利用(yong)率和作业效率。探索解决小(xiao)农(nong)(nong)生(sheng)产(chan)与农(nong)(nong)机规(gui)模经营(ying)矛盾(dun)的有效途径，初(chu)步形成(cheng)了特色(se)农(nong)(nong)业机械化发展道(dao)路(lu)农(nong)(nong)机行业也迎来了新一(yi)轮的产(chan)品结(jie)构(gou)调(diao)整，高(gao)效大中型农(nong)(nong)机开(kai)始恢复增长(zhang)，小(xiao)型农(nong)(nong)机增速放缓，联(lian)合(he)收(shou)割机应运而(er)生(sheng)，一(yi)度成(cheng)为农(nong)(nong)机行业发展的支(zhi)柱产(chan)业。

事实上(shang)，农(nong)(nong)机(ji)更新换代是(shi)我国(guo)(guo)农(nong)(nong)业(ye)发(fa)(fa)展进程(cheng)的(de)一(yi)个(ge)缩影只(zhi)有(you)从无到有(you)，拖拉机(ji)逐步多样化，才从一(yi)个(ge)侧面印证了(le)中(zhong)国(guo)(guo)农(nong)(nong)业(ye)机(ji)械(xie)乃至整个(ge)中(zhong)国(guo)(guo)农(nong)(nong)业(ye)的(de)发(fa)(fa)展变化。

党的(de)十(shi)八大以来，农(nong)业科技创(chuang)新步(bu)伐(fa)明显加快，乡村(cun)振兴(xing)插上(shang)了科技的(de)翅膀。以拖拉(la)(la)机(ji)为例目前，国(guo)内已成功研制(zhi)出自主式和无人驾驶拖拉(la)(la)机(ji)。中国(guo)人工智能(neng)协会预测，到(dao)2030年(nian)(nian)，无人驾驶拖拉(la)(la)机(ji)将(jiang)在(zai)中国(guo)农(nong)村(cun)普及。与70年(nian)(nian)前拖拉(la)(la)机(ji)是“稀(xi)罕物”的(de)时代相比(bi)，中国(guo)农(nong)业机(ji)械化(hua)的(de)发展只能(neng)用“巨变(bian)”来形容。
