摘要
本文根据我国气候的基本特征 ,提出了发展营养体产业是高效利用我国土地资源和气候资源的有效途径的观点 ,比较了营养体产业和传统农业在光能利用和产量等方面的差别 ,指出了营养体产业的技术关键是科学利用 S-型生长曲线。
The climatic resources were compared between the north and the south of China in the study. Vegetative agricultural industry and traditional seed agriculture were contrasted in physiological ecology, cost inputs, utiliation efficiency of solar energy and vegetative and grain yields. The advantage of vegetative agricultural industry over the traditional seed agriculture was presented after a practical example from Zhejiang Province. Based on the differences of the requirements of irradiation between vegetative agriculture and traditional agriculture, to develop vegetative agricultural industry instead of focusing on traditional seed agriculture was proposed through the utilization of winter fallow croplands in China.
