农业是我国国民经济的基础,它直接涉及人们的温饱和工业生产的原材料等问题。而作物栽培不论在农业生产发展方面还是在农业科学进步方面都有着十分重要的作用。据有关方面估计,我国“六五”期间,农业增产原因除政策因素外,科学技术措施主要靠两条:一条是产业结构的合理调整,另一条就是良种和作物栽培技术的正确采用。当前我们正面临着席卷世界的新技术革命的挑战和本世纪末实现我国工农业总产值翻两翻 Agriculture is the basis of our national economy.

Crop cultivation plays a very important role both in the development of agricultural production and in the progress of agricultural science. According to the estimation of relevant parties, in addition to the policy factors, there are two main reasons for scientific and technological measures during the period of the “Six Five-Year Plan”: one is the rational adjustment of the industrial structure and the other is the proper adoption of fine and crop cultivation techniques. At present, we are facing the challenge of a new technological revolution sweeping the world and a reversal of the total output of industry and agriculture by the end of this century
