摘要:

于2023年11月—2024年5月在江苏南通沿海滩涂围垦区开展裸大麦种植试验,以‘苏裸麦2号’为试验品种,设置5个不同硅肥施用量处理,即对照(CK,0 kg/hm2)、SiF1(75 kg/hm2)、SiF2(150 kg/hm2)、SiF3(225 kg/hm2)和SiF4(300 kg/hm2),旨在研究增施不同用量硅肥对沿海滩涂土壤肥力及裸大麦产量、品质的影响。结果表明:(1)与CK相比,SiF1、SiF2、SiF3和SiF4处理下土壤有效磷含量显著提高,分别提高了19.31%、18.99%、23.16%和17.71%(P<0.05),SiF2、SiF3、SiF4处理还显著提高了土壤可溶性有机碳和易氧化有机碳含量,增幅分别为11.46%和11.61%、11.77%和8.39%、14.21%和9.03%(P<0.05);增施不同硅肥量处理下土壤总碳、有机碳、微生物量碳、总氮、铵态氮和硝态氮等含量变化均无显著差异(P>0.05)。(2)与CK相比,SiF2处理下沿海滩涂地区裸大麦产量提高了17.02%(P<0.05),且β-葡聚糖含量增幅最大;产量构成因素中,SiF2和SiF3处理下穗数显著增加,而不同硅肥处理下千粒重、每穗粒数均无显著影响。综上,增施硅肥可改善沿海滩涂土壤肥力,其中150 kg/hm2为适宜施用量,能有效提高滩涂地区裸大麦的产量及β-葡聚糖含量。

Abstract:

A bare barley planting experiment was carried out from November 2023 to May 2024 in the coastal reclamation area of Nantong, Jiangsu Province to study the effects of different amounts of silicon fertilizer on soil fertility and yield and quality of bare barley, with ‘Suluomai No.2’ as the test variety. Five different silicon fertilizer application rates were set up in the treatment, including CK, SiF1, SiF2, SiF3 and SiF4 (0, 75, 150 and 225 kg/hm2). The results showed that: (1) compared with CK, the soil available phosphorus concentration increased by 19.31%, 18.99%, 23.16% and 17.71% respectively under SiF1, SiF2, SiF3 and SiF4 (P<0.05). The concentrations of soil soluble organic carbon and easily oxidizable organic carbon increased by 11.46% and 11.61%, 11.77% and 8.39%, 14.21% and 9.03%, respectively under SiF2, SiF3, and SiF4 treatments (P<0.05); there were no significant differences in the concentrations of total carbon, organic carbon, microbial biomass carbon, total nitrogen, ammonium nitrogen, and nitrate nitrogen under different silicon fertilizer application treatments (P>0.05). (2) Compared with CK, the yield of bare barley in the coastal tidal flat area increased by 17.02% under SiF2 treatment (P<0.05), and the β-glucan content of bare barley under SiF2 treatment increased the most. In terms of yield components, the number of spikes increased significantly under SiF2 and SiF3 treatments, while there were no significant changes in thousand-grain weight and the number of grains per spike under different silicon fertilizer treatments. In conclusion, the soil fertility of coastal tidal flat was improved by increasing the application of silicon fertilizer, and the yield and β-glucan content of bare barley in coastal tidal flat area were increased by increasing the appropriate amount of silicon fertilizer (150 kg/hm2).
