“南繁”作为我国首创的一种独特育种方式,在农作物品种培育过程中发挥着缩短育种年限,加速世代繁育的特殊作用。目前,在全国推广的5 000多个农作物品种中,约有80%经过了“南繁”的选育或者加代。在总结“南繁”现状的基础上,从充分利用“南繁”这一优势,加快优良农作物新品种的培育,促进粮食生产和农业稳定发展的角度,分析了在“南繁”中存在的规划、管理、基础设施建设和用地矛盾等制约其发展的几个问题,并提出了相应的建议。
As a unique breeding method pioneered by our country, “Nan Fan ” plays a special role in shortening the breeding period and accelerating generation breeding in the cultivation of crop varieties. At present, about 80% of the more than 5,000 varieties of crops spread throughout the country have undergone the breeding or addition of “Nanfan”. On the basis of summing up the status quo of “Nanfan ” and from the perspective of making full use of the advantage of “Nanfan ”, speeding up the cultivation of new fine varieties of crops and promoting the steady development of food production and agriculture, Many problems that restrict its development in planning, management, infrastructure construction and contradiction of land use are put forward.
