摘要
在大田栽培条件下,以‘花优14'为材料,对机插水稻的育秧、移栽、肥料运筹等进行定量栽培调控技术研究。结果表明:芽谷最适播种量为155~175g/盘;在行距30 cm固定情况下,栽插株距14 cm最有利于发挥‘花优14'的个体质量及群体水平;大田施氮量300 kg/hm^2、基蘖肥:穗肥=7:3处理产量最高;单位面积总颖花量的显著提高是‘花优14'机插栽培增产的主要因素。
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.
