转型期作物生产发展的机遇与挑战
Opportunities and Challenges for Crop Production in China during the Transi-tion Period
摘要
Abstract
China's crop production goes in to a transition period from the small household mode mainly with traditional manual works to the moderately large-scale mode with high degrees of mechanization, intensification and informatization. The important goal of crop production during this period is to simultaneously enhance productivity per unit land area and per capita. In recent years, steadily increased crop production capacity, significant change in crop production patterns and rapid development of industrial economy have created new opportunities for China's crop production during the transition period. But at the same time, new challenges have also been raised, including shortened crop growth duration in multiple cropping systems, increased seed rate per unit land area and decreased values of heterosis. Aiming these challenges, we proposed that crop production researches should be focused on developing high light-efficiency cultivation technologies through dense planting, improving seed quality of hybrid crops and strengthening collaboration between breeders and agronomists during the transition period.关键词
