为了探索在相同地力、相同处理条件下水稻的高产原因 ,对比了黑龙江省佳木斯2013年与2014年3-9月每月日平均温度、相同试验水平下的叶龄进程、产量构成因素.结果表明 :2014年比2013年高产原因主要是2013年结实期温度不足 ,导致2013比2014年结实率低16 .6百分点 ,每穗粒重低0 .64 g.

In order to explore reason of high yield of rice in the same soil ,the same processing conditions ,the month and daily average temperature from March to September in 2013 and 2014 in Jiamusi City of Hei-longjiang province were analyzed ,leaf age process of the same experiment condition was discussed ,yield and its constitute factors were analyzed .The results showed that the main reason of the 2014 yield was higher than that in 2013 ,it was the lack of the low temperature environment at grain-filling stage in 2013 ,as compared with the seed setting rate and seed weight per panicle in 2014 ,it reduced by 16 .6 percent point and 0 .64 gram in 2013 respectively .
