农业生产说到底是一个物质和能量的转化过程。这一客观特性,给我们农业科研工作者和农业生产者,提出了一项根本任务。这就是说,我们对一切农业活动应该是:一方面要遵守能量守恒定律,为求得农业“产出”多,必须有相应的物质和能量的“投入”;另一方面,又应寻求生态规律和经济规律,充分而合理地利用自然资源与社会资源。提高农业生产过程中物质和能量的转化效率,使等量的“投入”获得较多的“产出”,达到最佳的经济效果。
After all, agricultural production is a material and energy conversion process. This objective character poses a fundamental task for our agricultural researchers and agricultural producers. That is to say, we should take all agricultural activities as follows: on the one hand, we must observe the law of conservation of energy, and in order to obtain more “output” of agriculture, we must have the “inputs” of material and energy; on the other hand, Laws and economic laws, full and reasonable use of natural resources and social resources. Improve the efficiency of material and energy conversion in agricultural production, so that the same amount of “input” can obtain more “output” to achieve the best economic results.
