寒地水稻2014年较2013年高产原因分析
Analysis on Reason of High Yield of Rice in Cold Region in 2014 than in 2013
摘要
Abstract
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 .关键词
