Effect of pot seedling machine transplanting on yield and quality of different hybrid late rice varieties
Seedling machine transplanting technology is widely used in rice.In 2021,four hybrid late rice varieties,including Zhongzheyou 8,Tailiangyou 217,Jiafengyou 2 and Yongyou 15,were selected to analyze and compare the effects of two seedling raising machine transplanting methods,pot seedling machine transplanting and blanket seedling machine transplanting on seedling quality,yield composition and rice quality of different single-season late rice varieties.Machine transplanting of pot seedlings can increase rice yield,mainly due to the good quality of pot seedlings,more dry matter accumulation,early seedling growth,significant increase in the number of grains per spike,and stable seed setting rate and 1 000-grain weight.However,the improvement effect on rice quality was not obvious,and only the chalkiness was reduced.The influence of pot seedling machine transplanting technology on rice yield and rice quality was studied in depth,and high-quality single-season late rice varieties suitable for pot seedling machine transplanting were screened to achieve the purpose of high quality,stable yield and cost saving,so as to provide a technical path for the promotion of pot seedling machine transplanting.
