实践经验证明:传统农业一般仅有量的变化,而没有质的创新,工具简陋,生产手段简单,也可以说是一种主要依赖于天赋自然资源的粗放耕作农业。但就其本身来讲,尽管生产要素的配置都是相当有效的,但由于它不能为经济增长作出较大贡献,所以长期以来,中国农业科技总体水平与国外相差较大。据有关资料介绍,农业科技转化率、化肥当季利用率、灌溉水利用
Practical experience shows that traditional agriculture is generally only a quantitative change, without qualitative innovation, simple tools, simple means of production, it can be said that a largely dependent on the natural resources of extensive farming. However, as a matter of fact, although the allocation of factors of production is quite effective, its overall level of agricultural science and technology in China has long been a big gap with that of other countries because it can not make a significant contribution to economic growth. According to relevant information, the conversion rate of agricultural science and technology, seasonal utilization of chemical fertilizers, irrigation water use
