Abstract
In recent years,a vast number of high-quality rice varieties and their supporting technologies have been widely promoted in Guangdong Province,resulting in a significant increase in the planting area of silk seedling rice,of which 19 Xiang is representative.In 2020,the annual yield of 19 Xiang in Xingning City was 1300.12 kg/667 m2(1 mu),breaking the national record for the average annual yield of double season fragrant rice per mu.In addition,this variety has good field performance during demonstration planting,with a medium-set plant shape,strong tillering ability,long spikes and multiple grains,and strong lodging resistance.Based on this,the article summarizes the key cultivation techniques and management measures of 19 Xiang,with a view to providing reference for the high-yield cultivation of silk seedling fragrant rice varieties and contributing to China's food security.
