摘　　要：为了探明专用肥对花生的施用效果,于2021年进行了活性腐殖酸复合肥试验。以普通三元复合肥(CK1)和不施肥(CK2)为对照,设腐植酸肥750 kg/hm^(2)(T1)、腐植酸肥609 kg/hm^(2)(T2)、腐植酸肥525 kg/hm^(2)(T3)3个梯度处理,研究不同腐殖酸肥用量对花生生长发育和产量的影响。结果表明,T1、T2和T3处理的分枝数、主茎绿叶数和单株饱果数均高于CK1和CK2;播种后第108 d时,T1的单株干物质较T2和T3分别增加1.6%和10.3%;与CK1和CK2相比,腐殖酸肥处理下的花生饱果数、饱仁数、百果质量和百仁质量具有显著优势,随腐殖酸肥用量的增加,花生产量有明显上升趋势,T1可获得较高的产量,达到5 194.8 kg/hm^(2)。可见,施用活性腐殖酸复合肥750 kg/hm^(2)能够促进花生生长发育,增产作用明显。In order to investigate the effect of specialty fertilizer application on peanut, a trial of active humic acid compound fertilizer was conducted in 2021. Ternary compound fertilizer(CK1) and no fertilizer(CK2) were used as controls, and three gradient treatments of humic acid fertilizer as 750 kg/ha(T1), 609 kg/ha(T2) and 525 kg/ha(T3) were set to study the effects of different application rates of humic acid fertilizer on growth and yield of peanut. The results showed that branch number, main stem green leaves number and plump pod per plant of T1, T2 and T3 were higher than those of CK1 and CK2. On the 108 th day after sowing, the dry matter accumulation per plant of T1 increased by 1.6% and 10.3% compared to T2 and T3, respectively. Compared with CK1 and CK2, the plump pod number, plump kernel number, 100-pod mass and 100-kernel mass under the humic acid fertilizer treatment had significant advantages, and with the increase of application rates of humic acid fertilizer, the yield of peanut manifested significant upward trend, and T1 could obtain the highest yield as 5,194.8 kg/ha. It can be found that the application rate of active humic acid compound fertilizer 750 kg/ha could promote the growth of peanut, and the effect of yield increase was significant.
