Abstract:

Based on the survey data collected of 8 counties （districts） in Jiangxi province, the effects of farmers’ personal characteristics and rice planting area on extension of mechanical transplanting rice were analyzed with grey relational degree model. The results showed that the grey correlation degree between rice planting area and personal characteristics and rice mechanical transplanting were 0.93 and 0.76 respectively, they were two important factors that affecting the extension of mechanical transplanting rice. Among the personal characteristics, educational level, age of the farmers and the total number of family labor force were the dominant factors, and their grey correlation coefficients with the main behavior of the system were 0.91, 0.86 and 0.83, respectively.

Key words: personal characteristics, planting area, rice mechanical transplanting, grey correlation coefficient

摘要：

基于江西省8县（区）的调研数据，应用灰色关联度模型，分析研究了人员特征和家庭种稻面积对水稻机插技术推广的影响。结果表明，水稻种植面积和人员特征与水稻机插的灰色关联度分别为0.93和0.76，是影响水稻机插技术推广的2个重要因素。在人员特征中，文化程度、年龄和家庭劳动力人口总数是主导因素，它们与系统主行为灰色关联系数分别是0.91、0.86和0.83。
