The Effect Of Operational Applying Different Fertilizer On Some Physiological Characteristics And Yield And Kernel Quality Of Peanut

The studies were conducted from 2004 to 2005 in the experimental station and the crop high yield physiological lab of Shandong Agricultural University, Taian, china. Fenghua1, widely planting peanut variety, was chosen in this study. The experiment designed in field experiment combining with pool experiment. The effects of applying amount and proportion of N,P,K and Ca fertilization on peanut yield, kernel quality and some physiological characteristics were studied. Changes of fat, protein and total sugar in kernel were also investigated. The main results were as follows.1 Different applying amount of N, P, K and Ca fertilizer on some physiological characteristics and yield in peanut1.1 Effect of different applying amount of N, P, K and Ca on plant character Different fertilizer affected the vegetation growth differently, Ca could control vegetation growth of peanut, in favor of preventing over growth and falling over. N, P and K had no prominent effect on the main stem height and cotyledonary branch length. Fertilizer could reduce the number of branch, have advantage of improving plant types, avoid redundant branches affecting aeration and sunlight transmission.1.2 Different applying amount of N, P, K and Ca fertilizer on some physiological characteristics in peanutDifferent applying amount of N, P, K and Ca increased the content of chl(a+b) in leaves during pod setting and filling stage, especially Ca.
