Cultivation techniques of"six suitability and three high"for regenerated rice
To scientifically guide the planting and management of regenerated rice and promote the promotion and application of related cultivation techniques.The cultivation practice of regenerated rice in Taoyuan County,Changde,Hunan Province was combined,the specific key points of its"six suitability and three high"cultivation techniques were summarized and analyzed.This technology was developed by suitable varieties(selecting rice varieties with suitable growth periods,good comprehensive resistance,excellent rice quality,and high annual yield),timely sowing(ensuring full heading before the arrival of cold dew winds during the regeneration season),moderate planting(field planting amount of 26.25-30.00 kg/hm2),suitable management(scientific water management,rational fertilization,prevention and control of diseases,pests and weeds,and timely harvestiong),suitable machinery(choosing specialized harvesting machinery for regenerated rice or replace narrow tracks to reduce the area of rice pile compaction),and appropriate pile retention(regenerated rice emergence was affected by factors such as temperature and variety characteristics,with a suitable pile height of 20-40 cm).Based on the current situation of regenerated rice cultivation in the research area from 2020 to 2023,through the application of this technology,the high yield,high quality,and high efficiency of regenerated rice have been achieved.The research results provide references for promoting sustainable production of regenerated rice.
