Comparative Analysis of Technical Efficiency and Labor-saving Effect of Water-saving and Drought-resistance Rice
A comparative analysis was conducted on the technical efficiency and labor efficiency of water-saving and drought-resistance rice and ordinary rice by questionnaire survey among farmers in three major rice-growing counties in Anhui Province.It was found that the average technical efficiency of water-saving and drought-resistance rice cultivation was 0.895,which was higher than that of ordinary rice of 0.887.Planting water-saving and drought-resistance rice could improve the technical efficiency level of farmers.The average labor input of water-saving and drought-resistance rice in the overall production process was 333.00 h/hm2,which was 37.95 h/hm2 less than that of ordinary rice,and 88.50 h/hm2 less than that of ordinary rice in planting,showing obvious labor saving advantage.The analysis of influencing factors on labor input showed that the expansion of planting scale and the improvement of farmers'education level were conducive to the reduction of labor input per unit area.
