Effects of"3414"Fertilizer Application on the Yield of Fagopyrum cymosum
摘要
Abstract
Objective:To study the effects of different fertilizer applications on the yield of Fagopyrum cymosum and explore the bese scheme for getting the maximum yield on purple soil in the Chongqing-west Methods: Experiment with implementing plan of “3414” ;The quality Assessment by the contents of bipoly-chrysanthemin;The data process program under the Excel 2003 ,SPSS 13. 0,Matlab 7.0,Word 2003 environments. Results:Various fertilizer combinations had different transformation efficiency which the N3P2K2.combination was the maximum 97. 09％ and the N0P2K2 combination was the minimum 4. 32％ ;The N0P2K2 combination had the lowest yield except of the bland group which was 186 kg/667 m2 ;When the N fertilizer Rate was controlled in the level of 15 kg/667 m2,The yied had no obvious change as the increase of another two kinds fertilizer rate ;Three kinds of function could better reflect the relationships between fertilizer and yields ,which all of the R2 value were above 0. 88 ;The best one was N K function with the maximumR2;The blank group had maximum content 8.67％ of bipoly-chrysanthemin and the content had a little decrease as the increase of N or K,but all higher than 7. 14％ which were planted in Bei Jing area. Conclusions:Various fertilizer combintions influenced the transformation efficiency of N、P、 K;N is the key fertilizer on purple soil; Reconmentation funtion was N, K fimction which could be as the guiding function; F; Fertilizer would not influence the quality of Fagopyrum cymosum.关键词
