摘要
通过设定品种技术扩散指标,定量研究江苏省小麦品种技术扩散状况。"t-检验"分析表明,淮南、淮北小麦品种技术扩散存在显著差异。品种技术来源途径与转化周期、主体品种布局和地区社会经济环境是影响品种扩散的三个主要因素。合理的品种推广规划及良好的品种扩散环境,有利于提高品种技术转化率和应用效率。
The article aims to measure the variety technology extension of Jiangsu Province by the supposed Variety Technology Spread Index. The “t-test” analysis shows that the differences of wheat variety technology spread is obvious in different areas in Jiangsu Province. Further analysis shows the causes for the differences as follows： the variety creation and turnover, the variety distribution, the different growing space condition, etc. Reasonable variety plan and good variety diffusion environment will be advantageous to raising the variety technology conver- sion rate and application efficiency.
