杂交晚粳‘花优14’机插栽培高产技术研究
High-yield technology of japonica hybrid rice‘Huayou 14’ cultivated by mechanical transplanting
摘要
Abstract
Under field condition,‘Huayou 14’as test material,quantitative cultivation technology of mechanical transplanting rice was studied in terms of sprout cultivation,transplantation and fertilization strategies.The results showed that sprout seeding rate was optimal at 155 ~ 175 g/tray;When array pitch fixed at 30 cm,row spacing at 14 cm was optimal for individual quality and population levels;When nitrogen at 300 kg/hm2 and the ratio of basal fertilizer/bud fertilizer was 7∶3, the yield was the highest;The significant increase on total number of spikelets per unit area was the primary reason for the production increase of ‘Huayou 14’cultivated by mechanical transplanting.关键词
