摘要
选用主推大花生品种湘花2008,在湖南省邵阳县进行了腐植酸缓释肥试验,以探讨活性腐植酸缓释肥肥效后移的增产效果及适宜施用量。结果表明:施用活性腐植酸缓释肥和掺混肥均能促进花生茎和枝的生长发育,其中666.7m2施用45 kg腐植酸缓释肥的效果最好;同时,施用腐植酸缓释肥和掺混肥均能增加荚果产量,施用量越多,荚果产量越高,但施用腐植酸缓释肥的产量均低于掺混肥。
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 666.7m^2 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.
