大米是浙江省最重要的口粮品种。促进水稻生产稳定发展是确保浙江省粮食安全的关键举措之一。本文在简要分析浙江省水稻现实生产力的基础上,测算了水稻生产潜力,并针对制约浙江省水稻生产的因素,提出相应的对策。研究表明,通过恢复双季稻面积,可新增生产能力336万t;提高现有成熟技术到位率,提高单产可新增生产能力60万t;若两个条件均能充分发挥,浙江省水稻潜在生产力可达到1249万t,比现实生产力高582万t。提出必须优化生产扶持政策,加大中低产田改造,优化品种结构,提高技术到位率,推进规模经营,促进全面均衡增产。
Rice is the most important variety of rations in Zhejiang Province. To promote the stable development of rice production is one of the key measures to ensure food security in Zhejiang Province. Based on a brief analysis of the actual productivity of paddy rice in Zhejiang Province, this paper estimates the potential of paddy production and puts forward corresponding countermeasures in view of the factors restricting paddy production in Zhejiang Province. The research shows that by restoring the area of double cropping rice, the production capacity can be increased to 3.36 million tons; the existing mature technology can be put into place and the yield can be increased by 600,000 tons; if both conditions can be fully utilized, Potential productivity can reach 12.49 million tons, 582 million tons higher than the actual productivity. It is suggested that we must optimize production support policies, increase the transformation of middle and low-yielding fields, optimize the product mix, raise the rate of technology in place, promote the scale operation and promote a comprehensive and balanced production increase.
