Abstract：Using the main popularized peatnut variety Xianghua 2008 as material, the tests were carried out in Shaoyang County of Hunan Province to study the yield -increasing effects and optimal application rate of activated humic acid slow -released fertilizer ( HF) .The results showed that the growth and development of peanut stem and branches could be promoted by both HF and mixing fertilizer ( MF);the effects were the best at 45 kg per 666.7m2 of HF.The pod yield could be increased by HF and MF;the more the application rate was, the higher the yield could be obtained .But the pod yields of HF treatments were all lower than those of MF treatments .
