摘要
为研究不同机械种植方式对水稻产量的影响,2010—2012年在肇庆市怀集县以人工手插为对照进行3种机械种植方式对水稻产量影响的比较试验。结果表明:与人工手插相比,机直播生育期缩短15 d左右,机械插秧种植的生育期与人工手插基本相当;2010、2011年,毯状机插、钵毯机插和机直播的产量均低于人工手插,但机直播的平均日产量高于人工手插;2012年毯状机插、钵毯机插的产量都高于人工手插,机直播的产量与人工手插基本相当,3种机械种植方式的平均日产量均高于人工手插。
Artificial transplanting was used as control treatment, the effect of 3 different mechanical planting modes （carpet mechanical transplanting, bowl-carpet mechanical transplanting and mechanical direct seeding ）on rice yield was studied in Zhaoqing in 2011 to 2012. The results showed that ： compared with artificial transplanting, mechanical direct seeding shortened the growth duration by about 15 days, and the duration of mechanical transplanting was the same as artificial transplanting; compared with artificial transplanting, the rice yield of carpet mechanical transplanting, bowl-carpet mechanical transplanting and mechanical direct seeding decreased in 2010 and 2011, average daily production of carpet mechanical transplanting and bowl-carpet mechanical transplanting were lower than that of artificial transplanting, while that of mechanical direct seeding was higher than artificial transplanting in 2010 and 2011; the rice yield of carpet mechanical transplanting, bowl mechanical transplanting increased and mechanical direct seeding was the same as artificial transplanting in 2012; average daily production of mechanical planting methods were higher than that in the artificial transplanting in 2012.
