杂交中稻在不同地域和施氮水平下氮、磷、钾稻谷生产效率的差异性研究
Study on the Variation of Grain Productive Rate of N, P, K for Mid-Season Hybrid Rice in Different Ecology Area and Nitrogen Application Level
摘要
Abstract
The experiment was conducted with 2 mid-season rice combinations grown under the condition of different ecological site,basic fertility of soil and the level of N application in 2009.The data were analyzed by variance,correlation,regression and partial correlations.The results indicated that the differences of grain productive rate (GPR) of N are highly significant in different experiment combinations,sites,and levels of N application.The mutual effect of experiment site and N application level was significant on GPR of N,the differences of GPR of P,K in different experiment sites and N application levels were significant at 0.01 or 0.05 level.GPR of N of'Yuxiangyou 203'was higher than that of'Ⅱ-You 7'.Highly significant positive correlations were observed among GPR of N,P,K.The suitable environment conditions for increasing GPR of N,P and K are low longitude,high altitude,high organic fertilizer,high available P,high pH and low level of N application.关键词
