论中国水稻生产能力
Rice Production Capacity in China
摘要
Abstract
Rice production development is the key to maintaining the food security in China. To know the rice production potential in China, the levels of realistic productivity, actual production capacity and potential production capacity were calculated. The actual rice production capacity and potential production capacity in China could reach 226. 2 and 253. 9 million tons, respectively, 34. 28 and 62. 00 million tons higher than the realistic productivity. Moreover, the causes for the stagnant increase in rice yield per unit area were discussed and the scientific and technical strategics for promoting rice productivity were put forward. To further improve the rice production capacity and steadily increase national rice production, some measures are suggested, i. e. strengthening the amelioration of medium and low yield fields to improve the quality of farmland, making efforts on super high-yielding rice breeding and extension to form the variety structure dominated by widely adaptive super high-yielding rice cultivars, optimizing cultivation techniques for super high yield to construct a low-cost and high-efficiency production technology system with simplified techniques at its core, and strengthening agricultural technology extension to reduce the yield difference between realistic yield and potential yield. In short, it is needed to promote scientific and technical supporting ability to the productive capacity of rice.关键词
