摘要

To meet the increasing worldwide demand for rice, cost reduction and higher productivity are among the essential targets for researchers and engineers. To attain this goal, high-density seedling technology has been developed that considerably lowers the number of nursery trays to one-third, nursery costs by half and transplanting hours to one-third. Nonetheless, because of high-density sowing, seedling growth starts to stall over 20 days after sowing (Yanmar, 2018); therefore, seedlings need to be transplanted within a short period of time, which limits farm management, especially for large-scale farmers. The present study proposes a new seedling arrangement that reduces the quantity of seeds per tray and consequently prolongs the viability of seedlings. When arrayed rice mat seedlings are made by sowing seeds in lines equal to the lateral feed number of the transplanter, the mat covers the same area as that of a conventional uniformly-sown mat, but with a reduced quantity of seeds. Of particular note is that, apart from saving seeds, the reduced density of seeds contributes to providing more nutrients, light and aeration to each plant, thus the seedlings would continue growing and last longer, allowing a longer period of transplanting for farmers.
