Research Progress and Development Straitegies on Ratoon Rice in Southern Henan
摘要
Abstract
This paper introduces the current production status of ratoon rice in southern Henan and provides a comprehensive overview of recent research progress in this region concerning the ecological adaptability,variety identification,high-yield cultivation techniques,and innovation in cultivation models of ratoon rice.It also proposes a"four-early and one-high"cultivation strategy for ratoon rice in southern Henan,which involves"selecting early-to mid-maturing varieties,sowing and nurturing seedlings earlier at an appropriate time,transplanting seedlings early in a timely manner,harvesting the main crop early,and maintaining a high stubble height at the time of main crop harvest".Meanwhile,specific agronomic indicators suitable for ratoon rice varieties in southern Henan are clarified:a growth duration of 120 to 136 days,129 to 173 grains per panicle,a tiller number per plant reaching or exceeding 11.5,and a ratooning bud sheath emergence rate of≥75.3%on the 5th day after the main crop harvest.Furthermore,the paper highlights the challenges faced in ratoon rice production in southern Henan,including vulnerability to low-temperature and cold damage during early spring seedling raising,difficulties in effectively applying bud-promoting fertilizer,high loss rates during mechanical harvesting,and the ineffective implementation of rice subsidy policies.To address these issues,relevant solutions are proposed.关键词
