摘要:

为探究不同新型肥料对典型黄河故道区土壤养分、土壤微生物群落及作物产量的影响,本研究开展田间定位试验,设置CK(常规施肥)、NM(增施氮肥187.5 kg·hm-2与微生物菌剂30 kg·hm-2)、F(施用生物有机肥6 000 kg·hm-2)、FE(施用生物有机肥6 000 kg·hm-2+土壤酶制剂15 kg·hm-2)共4个处理,待作物收获后测定土壤理化性质、土壤酶活性及作物产量等指标,并采用16S rRNA高通量测序技术对土壤细菌群落的组成进行分析。 结果表明,与CK相比: F和FE处理的土壤有机质和有效磷含量显著(p<0.05)升高,增幅分别为16.90%~22.17%、78.39%~207.70%,而NM处理的土壤有机质和有效磷含量分别显著降低22.64%和24.91%;NM、F、FE处理的土壤pH值均显著降低,降幅在1.55%~2.46%;NM处理的土壤β-葡萄糖苷酶、纤维二糖水解酶活性显著增强,增幅分别为56.42%、139.26%,而F、FE处理的α-葡萄糖苷酶、β-葡萄糖苷酶、酸性磷酸酶活性显著减弱,降幅分别为73.50%~78.42%、33.15%~36.72%、23.72%~28.64%。在土壤细菌群落丰富度上,NM处理较CK显著下降,而F处理较CK显著增加。在门水平上,与CK相比:F处理变形菌门的相对丰度从33.3%下降至27.8%,绿弯菌门的相对丰度从19.3%上升至22.3%,拟杆菌门的相对丰度从7.3%上升至9.2%;FE处理拟杆菌门的相对丰度从7.3%上升至8.4%。与CK相比,各处理均能提高稻、麦产量,其中,FE处理的增幅最大,并在改善千粒重等产量结构方面具有明显优势。

Abstract:

To investigate the effects of different new-type fertilizers on soil nutrients, soil microbial community, and crop yield in the typical ancient course area of Yellow River, a field location experiment was conducted in this study. Four treatments were set up, including CK (conventional fertilization), NM (additional application of nitrogen fertilizer at 187.5 kg·hm-2 and microbial agent at 30 kg·hm-2), F (application of bio-organic fertilizer at 6 000 kg·hm-2), and FE (application of bio-organic fertilizer at 6 000 kg·hm-2+soil enzyme preparation at 15 kg·hm-2). After crop harvest, indicators such as soil physicochemical properties, soil enzyme activities, and crop yield were determined, and 16S rRNA high-throughput sequencing technology was used to analyze the composition of the soil bacterial community. The results showed that, compared with CK: the contents of soil organic matter and available phosphorus under the F and FE treatments increased significantly (p<0.05) by 16.90%-22.17% and 78.39%-207.70%, respectively; in contrast, the contents of soil organic matter and available phosphorus under the NM treatment decreased significantly by 22.64% and 24.91%, respectively. The soil pH values under the NM, F, and FE treatments all decreased significantly by 1.55%-2.46%. The activities of soil β-glucosidase and β-D-cellobiohydrolase under the NM treatment increased significantly by 56.42% and 139.26%, respectively; however, the activities of α-glucosidase, β-glucosidase, and acid phosphatase under the F and FE treatments decreased significantly by 73.50%-78.42%, 33.15%-36.72%, and 23.72%-28.64%, respectively. In terms of soil bacterial community richness, the NM treatment showed a significant decrease compared with CK, while the F treatment showed a significant increase compared with CK. At the phylum level, compared with CK: under the F treatment, the relative abundance of Proteobacteria decreased from 33.3% to 27.8%, the relative abundance of Chloroflexi increased from 19.3% to 22.3%, and the relative abundance of Bacteroidetes increased from 7.3% to 9.2%; under the FE treatment, the relative abundance of Bacteroidetes increased from 7.3% to 8.4%. Compared with CK, all treatments could increase the yield of rice and wheat. Among them, the FE treatment had the largest yield increase and showed obvious advantages in improving yield components such as 1 000-grain weight.
