AA STUDY ON ENERGY FLOW OF THE CROP GROWING SUB-SYSTEM IN GUANGDONG
Abstract
On the basis of the data collected from various fields , the energy input output state in the crop-growing sub-system in Guangdong is estimated and analyzed. Results show that the input of the artificial supplementary energy is approximately 201x105 Kcal/ha. year and the input and output ratio equals 1 : 4.73. Measures for improving productivity and speeding up the development of agricultural mechanization in Guangdong are eventually suggested.
