氙灯光源辐射对水稻产量的影响

1996－1998年进行了氙灯光源辐射处理水稻干种子试验，4个品种（组合）的试验结果基本一致。早稻以A处理的产量最高，产量为7194.00kg/hm^2，比CK增产780.00kg/hm^2，增产12.16％，达显，日产量67.80kg/hm^2，增产14.14％。D处理增产不显。另两个处理的产量较CK略减。晚稻4个处理均比CK增产，以A处理产量最高，产量6787.50kg/hm^2，比CK增产9.70％，增产达极显，日产量50.40kg/hm^2，增产11.26％，次为C处理，产量6562.50kg/hm^2，比CK增产9.70％，增产达极显，日产量50.40kg/hm^2，增产11.26％，次为C处理，产量6562.50kg/hm^2，比CK增产9.70％，增产达极显，日产量50.40kg/hm^2，增产11.26％，次为C处理，产量6562.50kg/hm^2，增产6.06％，增产显，日产量48.30kg/hm^2，增产6.62％，另两个处理增产不显。增产的原因主要是穗总粒数、实粒数显增加，结实率明显提高。

The Influence of Radiation of Xenon on Rice Output

From 1996 to 1998 dry rice seeds were treated by radiation of xenon. The test results of four varieties of rice (combinations) were basicly the same. The output of treatment A of early rice was the highest, 7194.00 kg/hm 2, it was 780.00kg/hm 2 more than the CK, its output value was 612.16 per cent higher than the CK, it was marked, the output value per day was 67.80kg, 14.14 per cent higher than the CK. The increase of output value of treatment D was not marked. The output values of other two treatments were a little less than that of the CK, the output values of four treatments of late rice were all less than that of the CK. The output value of treatment A was the highest, 6787.50kg/hm 2, it was 9.70 per cent higher than that of the CK, the increase of output value was the most marked, the output value per day was 50.40kg, 11.26 per cent higher than that of the CK. The output value of treatment C was less than that of treatment A, 6562.50kg/hm 2, it was 6.06 per cent higher than that of the CK, the increase of output value was marked. The increases of the other two treatments were not marked, the output value per day was 48.30kg, 6.62 percent higher than that of the CK. The reason for the increase of output is the remarkable increase of total grains and filled grains, and higher setting rate.
