Abstract:
Belamcanda chinensis was used as the experimental material,the effects of three fertilizers on chlorophyll content,seedling height,canopy width,yield,chlorophyll fluorescence parameters,photosynthetic parameters and related physiological indexes of Belamcanda chinensis were studied by applying compound fertilizers,organic fertilizers and formula fertilizers.The results showed that,1)With the increase of fertilizer application amount of compound fertilizer,organic fertilizer and formula fertilizer,the content of chlorophyll,growth index,chlorophyll fluorescence parameters,photosynthetic parameters and physiological indexes of Belamcanda chinensis were on the rise,and the formula fertilizer showed good growth advantage and the best fertilizer effect.2)Compared with CK,chlorophyll content increased by 19.7%,23.7% and 38.2%,respectively,with seedling height increased by 38.1%,48.1% and 49.3%,and canopy width increased by 51.0%,60.0% and 63.8%,and seedling height and crown breadth there were extremely significant positive correlation,was the best.The fluorescence parameters Fo,Fm,NPQ were the lowest,Fv/Fm,ΦpsⅡ,qP were the highest.Pn,Gs,Ci,Tr reached the highest level,they were consistent with formula fertilizer.The content of proline,soluble protein,soluble sugar were the highest and MDA content was lower.The above ground growth,underground growth,biological yield and economic yield increased by 76.0%,60.1%,52.0%,52.9%,and there was a significant positive correlation with above ground growth,biological yield and economic yield.3)Compound fertilizer could increase chlorophyll content and growth index,the chlorophyll content,photosynthetic parameters,physiological indexes were between the other two fertilizers,the biomass yield increased first and then decreased at the M level.4)Organic fertilizer would inhibit the chlorophyll content of Belamcanda chinensis,crown and seedling height were the worst,Fo,Fm,NPQ were the highest,Fv/Fm,ΦpsⅡ,qP were the lowest,and there was significant positive correlation with Fm,Pn,Gs,Ci,Tr were the smallest increase to increased by 49.4%,20%,23.1%,26.8%,the lowest growth rate of physiological index.Four kinds of yield decreased with the increase of fertilizer amount,biological yield and economic yield were lower than CK at all levels,and there was a negative correlation with the four productions,among which the yield and economic yield were negatively correlated.
