摘要: 选择陕北张家峁矿区黄土地,田间接种丛枝菌根真菌(Arbuscular mycorrhizal fungi,AMF),种植豆科作物豌豆(Pisum sativum L.),监测其生长、品质、产量和土壤理化特性。结果表明,接种菌根豌豆的菌根侵染率提高了16.11个百分点,菌根与豌豆可形成较好的共生关系。接种菌根后豌豆株高和SPAD比对照分别显著提高了52.34%和29.35%(P<0.05),秸秆生物量和产量分别提高了22.69%、20.61%,菌根植株全氮和全钾含量比对照分别提高了12.72%和22.19%(P<0.05),豌豆植株氮和钾总吸收量分别提高了38.74%和51.89%。接菌植物的品质改善,豌豆可溶性蛋白和可溶性糖分别提高了20.09%和47.99%。接种菌根对土壤电导率、速效磷、速效钾、有机质、全钾、全磷和全氮有增高的作用,对pH有降低的作用,但差异均未达显著水平。接种菌根对黄土农田植物生产力有较好的促进作用,微生物复垦对黄土高原农田生产力改良提供了一种较好的应用潜力。

Abstract: In this study, arbuscular mycorrhizal fungi (AMF) were inoculated in the loess land of Zhangjiamao mining area in north Shaanxi province, and the common local legume plant pea (Pisum sativum L.) was planted to monitor its growth and quality and yield, and soil physical and chemical properties. The results showed that the root colonization rate of pea increased by 16.11 percentage points, and a good symbiotic relationship between mycorrhizal and pea could be formed. Compared with the control treatment, the plant height and SPAD of pea increased by 52.34% and 29.35% (P<0.05), the biomass and yield of straw increased by 22.69% and 20.61%, the total nitrogen and potassium content of mycorrhizal plant increased by 12.72% and 22.19% (P<0.05), and the total nitrogen and potassium absorption of pea plant per hectare increased by 38.74% and 51.89%, respectively. The soluble protein and sugar of pea per hectare increased by 20.09% and 47.99%, respectively. Mycorrhizal inoculation increased soil conductivity, available phosphorus, available potassium, organic matter, total potassium, total phosphorus and total nitrogen, and decreased pH, but the difference was not significant. Inoculated mycorrhiza can promote the productivity of plants in the Loess Plateau, and microbial reclamation can provide a good potential for the improvement of productivity in the Loess Plateau.
