Abstract:

Ratoon rice is a highly efficient special rice cropping mode that can have another harvest in a short period of time without plowing and transplanting. It has a great significance to improving grain production, ensuring food security and increasing the comprehensive benefits of rice fields because of its advantages of saving time, labor and fertilizer, as well as environmental benign, high efficiency and simplification. In this paper, the development process and research status of ratoon rice were discussed in detail, and the effects of ratoon rice varieties, stubble height in harvest period, water management, plant growth regulators, nutrient management (bud-promoting fertilizer, seedling promoting fertilizer and selenium fertilizer) on the yield and quality of ratoon rice were summarized and analyzed. The innovative integrated field management rice farming models of "green manure +", "full mechanization +" ratoon rice were put forward to improve the soil environment of paddy fields, increase the income of farmers, and realize the green and modern production of ratoon rice. The development trend of ratoon rice was also prospected in order to provide reference for the development and application of ratoon rice.

Key words: ratoon rice, grain yield, fertilization, field management, green manure, full mechanization
