      characteristics, yield and kernel quality of peanut].
PG  - 2468-74
AB  - The field experiment was executed with peanut cv. Fenghua No. 1 from 2004 to 2005 
      in the experimental station of Shandong Agricultural University to study the 
      effects of N, P, K fertilizers application amount on physiological 
      characteristics, yield and kernel quality of peanut. The results showed that, 
      compared with no fertilization, application N, P, K fertilizers increased the 
      content of chlorophyll and soluble protein, enhanced photosynthetic rate and the 
      activities of superoxide dismutase (SOD), peroxidase (POD) and catlase (CAT), and 
      reduced malondialdeyde (MDA) accumulation amount in peanut leaves. The effects of 
      applying N 300-450 kg x hm(-2), P5O2, 150-225 kg x hm(-2) and K2O 300-450 kg x 
      hm(-2) treatments were the most significant. The improvement effect of N 
      fertilizer on photosynthesis properties was mainly at early stage, and that of P 
      was at middle-later stage, K was at whole stage. Applying N, P, K fertilizers 
      increased the pod yield of peanut remarkably, and with the increasing of N 
      application amount the pod yield enhanced, the pod yields were highest when P and 
      K application were at middle amount rates (P5O2, 150 kg x hm(-2) K2O 300 kg x 
      hm(-2)). The increasing effect on pod yield of K fertilizer was greater than that 
      of N and P fertilizers. Applying a small amount of P and K fertilizers (P2O5 75 
      kg x hm(-2), K2O 150 kg x hm(-2)) could significantly increase the contents of 
      fat and protein in peanut kernel, applying a small amount of N fertilizer (N 150 
      kg x hm(-2)) could significantly increase the content of protein in peanut 
      kernel, but applying a large amount of N fertilizer (N 450 kg x hm(-2)) could 
      significantly increase the content of fat in peanut kernel. Applying P fertilizer 
      obviously increased fat and protein content, applying N fertilizer mainly 
      enhanced protein content, and applying K fertilizer mainly raised the content of 
      soluble sugar. In addition, the application of N, P and K fertilizers also 
      increased the contents of lysine and methionine which were inadequate in the 
      protein fractions of peanut kernel, enhanced the contents of oleic acid and 
      linoleic acid, raised the ratio of oleic acid to linoleic acid, improved 
      nutritional quality of peanut, and pronged the shelf life of peanut products.
