    摘要:

    针对设施菜地施肥量大、肥料利用率低、果实品质变差、土壤环境劣质等问题,采用田间试验法,研究了无机肥配施不同土壤调理措施对设施黄瓜产量、品质、养分利用及土壤改良的影响,为实现蔬菜安全生产和保护土壤环境质量提供科学依据。结果表明:与农民习惯施肥相比,推荐无机肥配施生物菌肥、中微量养分、沸石处理的氮磷钾无机肥用量均减少40%左右,黄瓜产量却提高6.3%~8.7%,纯收入增加18 663~19 958元/hm2,其中推荐无机肥配施生物菌肥的整株植物氮、钾积累量分别增加13.3%和22.7%,土壤细菌、放线菌数量和细菌/真菌比值分别增加3.2,1.7,7.7倍;推荐无机肥配施沸石的整株磷积累量增加31.7%,表层土壤NH4+—N提升31.6%;配施生物菌肥和中微量养分处理的VC、可溶性蛋白和可溶性糖含量分别增加14.0%~18.6%,22.2%~34.6%,7.8%~10.0%,硝酸盐降低15.8%~21.7%。与推荐施肥比较,3种土壤调理措施氮磷钾肥生产效率提高6.2%~8.5%,氮磷钾肥农学效率增加26.1%~35.9%。说明3种土壤调理剂均促进黄瓜养分吸收,增加产量,改善其果实品质,降低土壤氮素残留,增加土壤有益微生物数量,其中以推荐无机肥配施生物菌肥既稳产提质,生物和土壤环境效益又较佳,值得在生产中推荐应用。

    Abstract:

    In view of the problems of large fertilizer application rate, low fertilizer utilization rate, poor fruit quality soil environment in facility vegetable fields, a field experiment was conducted to study the yield, quality, nutrient utilization, and soil of facility cucumber under different soil conditioning measures. The impact of the improvement would provide a scientific basis for the realization of safe vegetable production and protection of soil environmental quality. The results showed that compared with the conventional fertilization of local farmers, the recommended inorganic fertilizer combined with biological bacterial fertilizer, medium and micronutrients, and zeolite-treated N, P and K inorganic fertilizers were all reduced by about 40%, but cucumber yield was increased from 6.3% to 8.7%, and net income increase from 18 663 to 19 958 yuan/hm2. The nitrogen and potassium accumulation in the whole plant treated by inorganic fertilizer and biological bacterial fertilizer were increased by 13.3% and 22.7%, respectively. And the population of soil bacteria and actinomycetes and the ratio of bacteria/fungi were increased by 3.2, 1.7 and 7.7 times. The phosphorus accumulation in the whole plant treated by inorganic fertilizer and zeolite was increased by 31.7%. The surface soil NH4+—N content was increased by 31.6%. The contents of VC, soluble protein and soluble sugar under the application of biological bacterial fertilizer and medium and micronutrient treatment increased from 14.0% to 18.6%, 22.2% to 34.6%, 7.8% to 10.0%, and nitrate decreased by 15.8% to 21.7%. Compared with the recommended fertilization, the three soil conditioning measures increased the production efficiency of N, P and K fertilizers by 6.2% to 8.5%, and increased the agronomic efficiency of N, P and K fertilizers by 26.1% to 35.9%. All the three soil conditioners promoted cucumber nutrient absorption, increased yield, improved the fruit quality, reduced soil nitrogen residues, and increased the population of beneficial microorganisms in the soil. Among them, the recommended inorganic fertilizer combined with biological bacterial fertilizer were used to stabilize production and improve the quality of organisms and soil. With the better environmental benefit, it was recommended in facility cucumber production.
