Abstract
A field experiment was conducted to study the effects of different application rates of N,P,K and Ca fertilizer on photosynthesis properties,yield and kernel quality of peanut.The results showed that application of N,P,K and Ca fertilizer could increase chlorophyll content and photosynthetic rate in peanut leaves.The improvement action of fertilizer on photosynthesis properties,N was mainly at early stage,P was at middle-later stage,K and Ca was at whole stage.Application of fertilizer increased the pod yield of peanut distinctly,and with the increasing of N application rate,the pod yield of peanut was improved obviously,the pod yield of peanut was the highest when P,K and Ca application were at middle rates(P_(150),K_(300),Ca_(300)).Fertilization could increase the fat,protein and free amino acid content of peanut kernel,and improve kernel quality.The improvement action of fertilizer on kernel quality,P was the biggest,secondly were N and Ca,and K was indistinctly,over application of K fertilizer(K_(450)) could decrease the fat content of peanut kernel.Application of Ca fertilizer could increase the ratio of oleic acid and linoleic acid(O/L),and application of K could improve the content of soluble sugar of peanut kernel.
