摘要
应用旱育秧方式,采用随机区组设计,研究水稻机插秧在不同播期处理条件下,对油茬稻水稻机插用秧的适宜播种期及安全齐穗的影响。结果表明:在本试验条件下,油茬稻机插用秧在4月上旬至中旬播种移栽,8月中、下旬月平均温度达23℃以上,即可保证安全齐穗,且能获得较高产量。
The randomized block design was used to investigate effects of different sowing time on heading stage in raising rice seedlings by dry cultivation for transplanting seedlings by a machine, The results indicated that the suitable sowing time was in the first ten-day and middle ten-day period of April, which could make rice plants head safely in the middle ten-day and last ten-day period of August and gain the optimum rice yield .
