一、研究目的通过农业科学技术的研究,不断改进农业生产技术,克服限制农业生产的自然环境、社会和经济因素,使农业生产力(作物产量)逐渐提高,趋于稳定,并有可能达到最大生产力。但是,作物产量是有一定限度的,当其达到最大限度,时即使农业技术不断深入,或者是最有效的技术开发,也不能使产量再提高。这是因为农业生产虽然具有人为的技术设施,但仍然
I. RESEARCH OBJECTIVES Through agricultural science and technology research, continuous improvement of agricultural production technologies and overcoming the natural environmental, social and economic constraints of agricultural production have led to the gradual increase and stabilization of agricultural productivity (crop yields) and the possibility of reaching maximum productivity . However, there is a certain limit to the crop yield, and when it reaches its maximum, even if agricultural technology is deepened or the most effective technological development is carried out, the output can not be raised any further. This is because although agricultural production has man-made technical facilities, it remains
