Effects of Planting Methods on Rice Quality of Different Japonica Rice Varieties
In this study,A comparative experiment was carried out with medium-maturing early Liaogeng-138,Han-403,and Han-9710 in Liaoning province as experimental materials to study the difference in processing quality,appearance quality,nutritional quality,and value of cooking rice were compared and analyzed by transplanting and direct seeding.The results showed that planting methods had not effect on the processing quality and nutritional quality of rice.Compared with direct seeding,chalkiness,percentage of chalky grain and amylose content of transplanting were significantly increased by 42.4％,50.3％,and 15.0％,and value of cooking rice was significantly decreased by 12.9％.The peak viscosity,breakdown,and pasting temperature of transplanting were significantly higher than direct seeding,while the trough viscosity,final viscosity and setback were significantly lower than direct seeding.The milling percentage,value of cooked rice and breakdown in Liaogeng-138 were significantly higher than Han-403 and Han-9710,while the chalkiness,chalkiness rate,protein content,peak viscosity,trough viscosity,final viscosity,setback and pasting temperature of Liaogeng-138 were significantly lower than Han-403 and Han-9710.In this study,the effects of two planting methods on rice quality of different rice varieties were studied.Selecting reasonable planting methods and matching suitable high-quality rice varieties would be beneficial to obtain good quality traits of rice.Therefore,selecting mid-early matured japonica rice varieties and matching with direct seeding cultivation in the mid-matured areas of Liaoning can become the best production mode for achieving high-quality,high yield,and efficient utilization of temperature and light resources in japonica rice.
