Potted-Seedling Machine Transplantation Simultaneously Promotes Rice Yield, Grain Quality, and Lodging Resistance in China: A Meta-Analysis

Potted-seedling machine transplantation (PSMT) is an innovative method of mechanical rice transplanting to improve seedling quality and reduce injury relative blanket-seedling (BSMT). However, the responses yield, grain quality, risk lodging in PSMT have not yet been comprehensively defined. Here, we present a meta-analysis 67 peer-reviewed studies with 382 field observations investigate impacts on resistance mainland China. The results indicated that compared BSMT, increased aboveground biomass, nitrogen uptake by average 8.4%, 6.2%, 7.2%, respectively. boosted yield hybrid (+10.2%) more strongly than inbred (+6.9%). improved brown rate (+0.74%), milled (+1.1%), head (+2.3%), gel consistency (+4.4%) while reducing amylose content 3.7% no significant effects chalky rate, chalkiness, length/width ratio, or protein content. increase under was greater rice. reduced index at first (−5.1%), second (−9.4%), third (−8.0%) internodes. In conclusion, promising practice for simultaneously improving milling cooking eating paddies. addition, are higher those
