摘要:
研究不同施用条件下胶质类芽胞杆菌3016对花生生长、土壤酶活性及微生物多样性等的影响,为揭示该菌种的增产机理提供依据. 田间小区试验设置4个处理:T1(对照)、T2(接种3016)、T3(接种3016,50%的常规施肥量)和T4(常规施肥). 结果发现,T3处理花生单株总果数、单株总果重、百仁重、出米率和产量表现均为最高,分别高出对照27.1%、22.9%、7.8%、2.4%和10.4%;花生果仁和茎叶中养分含量与T4处理持平或略高,其中钾含量增加显著(P < 0.05),分别达到0.55%和1.19%;同时,T3处理土壤细菌、放线菌数量和土壤脲酶活性也显著(P < 0.05)高于对照,土壤菌群结构得以改善,有助于实现土壤肥力的提高. 因此,接种胶质类芽胞杆菌3016配施50%的常规施肥量,不仅能达到花生高产的目的,而且改善了土壤的生物学性状,是一种节本增效的施肥方式.
Abstract:
In order to reveal the yield-increasing mechanism of Paenibacillus mucilaginosus, a field experiment with different fertilizing modes was carried out. Four different treatments were designed, including T1 (control), T2 (no fertilizer but P. mucilaginosus 3016), T3 (P. mucilaginosus 3016 plus half of the regular fertilizer dose), and T4 (the regular fertilizer dose). The effects on peanut growth and soil microbiological characteristics were analyzed. The results showed that peanut characters under T3 were the best. The pod number per peanut plant, pod weight per peanut plant, hundred-pod weight, seed-producing rate and yield were higher under T3 than under T1 by 27.1%, 22.9%, 7.8%, 2.4% and 10.4%, respectively. The nutrient content of kernels, stems and leaves of peanut under T3 was equal or even a little more than that under T4. The contents of K were up to 0.55% in kernels and 1.19% in stems/leaves. Meanwhile, microbial population and soil urease activity under T3 were significantly high than that of T1 (P < 0.05), which could be helpful in improving soil quantity, microbial community structure, function and fertility. In conclusion, P. mucilaginosus 3016 plus half of the regular fertilizer dose can be an optimal fertilizing measure, not only increasing peanut yield, but also improving soil microbiological characteristics.
