Production Status and Development Countermeasures of Ratoon Rice in Zhejiang Province
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.
