试验于1986年在本所进行。设6月7、12、17日三个播期,亩播12.5公斤,每个播期分7月12、17、22日三个插期,共9个处理。重复三次,随机区组排列,小区面积0.03亩。试验结果如下: 1、生育期:观察结果表明,同一播期,一般是随着插期的推迟,全生育期天数有所延长;但同插期不同播期,随播期的推迟多数处理全生育期延长。秧龄相同的不同播插期全生育期天数变化有随播插期的推迟而延长的趋势。例如6/7播种,7/12、17、22日插秧的 The test was conducted in 1986 in our company. Set June 7, 12, 17 three sowing, acres sow 12.5 kg, each sowing on July 12, 17, 22 three insertions, a total of nine treatment. Repeat three times, random block arrangement, the plot area of ​​0.03 acres. The results are as follows: 1, the growth period: the observation results show that the same sowing date, usually with the postponement of the plug-in period, the number of days throughout the growth period has been extended; but different sowing date, with the sowing date most of the processing Growing period. The same number of different age of sowing the same period of growth throughout the growth period with the postponed extension of the extension of the trend. For example, 6/7 sowing, 7/12, 17 22 day transplanting
