摘要
再生稻具有一种两收、省种省工、减肥减药、增产增效等优势,是增加复种指数和提高水稻总产的一种种植模式.浙江是长江中下游重要的水稻生产区.本文依据种植品种的类型将浙江再生稻的发展历程分为3 个阶段,分别是以籼型早稻为主的起步阶段、以甬优 1540 为主的转变阶段和以甬优系列品种为主的快速发展阶段.以衢州市为例,再生稻的种植面积和产量在这 3 个阶段中不断提高,生产效益相较于单季稻和双季稻显著提升.在此基础上,进一步分析了浙江省再生稻发展前景以及高产稳产技术体系缺乏、农机农艺不配套、扶持力度低、品牌创建乏力等问题,并提出了相应的发展策略,以期为浙江省水稻生产方式转型升级提供参考.
Abstract
Ratoon rice,characterized by one sowing and two harvests,saving seed and labor,reducing fertilizer and pesticide,increasing yield and efficiency,is the main production system to increase multiple cropping index and improve the total yield of rice.Zhejiang Province is an important rice production area in the middle and lower reaches of Yangtze River.According to the types of cultivated varieties,the development of ratoon rice in Zhejiang Province was divided into three stages,namely,the initial stage of indica early rice,the transition stage of Yongyou1540,and the rapid development stage of Yongyou series varieties.Taking Quzhou City as an example,the planting area and yield of ratoon rice have been continuously improved in these three stages,and the production efficiency has been significantly improved compared with that of single cropping rice and double cropping rice.This paper further analyzed the development prospect and problems such as lack of technical system of high and stable yield,imbalance among agricultural machinery and agronomy,low support and lack of brand creation during the development of ratoon rice in Zhejiang Province,and put forward the corresponding development strategies,in order to provide reference for the transformation and upgrading of rice production system in Zhejiang Province.
