机械收割条件下再生稻研究进展及栽培策略
Research progress and cultivation strategies for ratoon rice under mechanical harvesting conditions
摘要
Abstract
Rice ratooning is a rice cultivation technique that enables a second harvest from the sprouted axillary buds on the remaining rice stubbles after the main crop has been harvested.This approach offers significant cost savings in terms of seed,fertilizer,labor,and time,while it also ensures exceptional rice quality and promotes environmental sustainability.These benefits are highly important for ensuring food security.Considering the unpredictable yield of ratoon rice under mechanical harvesting conditions,we briefly summarize the development history and yield potential of ratoon rice,analyze the key intrinsic factors(such as variety type and ratooning ability)and external environmental conditions(such as water and fertilizer management,stubble quality and mechanical harvesting modes,and pest and disease control)that affect the yield of ratoon rice.This review focuses on high-yield cultivation techniques of ratoon rice under mechanical harvesting conditions.We emphasize the importance of selecting varieties according to local conditions,sowing early according to light,temperature,and water conditions to ensure safe heading,strictly conducting three rounds of field drying,improving the performance of harvesters and optimizing their operation routes to reduce rolling damage,dynamically adjusting the applications of bud-promoting and seedling-promoting fertilizers according to stubble height,and achieving coordinated and increased panicle numbers and panicle sizes through rational water and fertilizer management.Finally,in response to production issues,we propose future research directions,including the breeding of high-quality ratoon rice varieties with high rolling resistance,the dissection of the water-fertilizer-microorganism-root physiological regulation network,and the optimization of the mechanical harvesting supporting cultivation technology system.关键词
