| 本研究旨在明确河北省饶阳县设施葡萄种植区土壤养分分布状况及肥力水平，为设施葡萄的合理精准高效施肥提供理论参考。本研究于2021年采集饶阳县设施葡萄种植区土壤样品75份，测定pH、有机质及大中微量元素含量，分析土壤样品的养分丰缺状况，并用隶属度函数和模糊数学综合评价法相结合的方法进行土壤肥力的综合评价。结果表明：全县设施葡萄园土壤pH平均值为7.84，各设施葡萄园之间差异不显著。土壤有机质含量平均值为17.07 g·kg-1，处于中等水平。整个研究区域硝态氮含量处于缺乏水平，碱解氮、有效铁和有效锰含量处于中等水平，有效磷、速效钾、全氮、全钾和交换性镁含量处于丰富水平，交换性钙、有效铜和有效锌含量处于很丰富水平，全磷含量处于极丰富水平。留楚镇和饶阳镇的土壤评价结果均为良好，大官亭镇、大尹村镇、王同岳镇和五公镇均为中等，东里满镇为一般。留楚镇和饶阳镇应适当补氮控磷钾，减灌水量降低氮淋洗。大官亭镇、大尹村镇应补氮减少灌水量同时减少含铜杀菌剂的使用，王同岳镇和五公镇应减少钾肥的投入。东里满镇应增施有机肥，减少钾肥的投入。在保障设施葡萄产量同时需考虑农业面源污染及养分高效利用的前提下，建议整个县域应适当控水补氮降钾，依区域调磷，降低钙镁锌肥的用量，减少含铜杀菌剂的使用。 |

| This study aimed to clarify the distribution of soil nutrients and the fertility level of facility grape growing areas in Raoyang County, Hebei Province, and to provide reference suggestions for assessing the potential of chemical fertilizer reduction in facility grape growing areas and rational fertilization of facility grape. In 2021, 75 soil samples were collected from facility grape growing areas in Raoyang County, and the pH, organic matter and large, medium, and trace elements nutrient content of the soils were determined to analyze the nutrient abundance and deficiency status and correlation of the soil samples, and to calculate the soil fertility level by using the affiliation function and fuzzy mathematics comprehensive evaluation method. The results showed that the average level of pH was 7.84, there was no significant difference between each facility grape vineyard. The average of soil organic matter content was 17.07 g·kg-1, which was at a medium level. In the whole study area the content of nitrate nitrogen, was at a deficiency level; the content of alkaline nitrogen, available iron and available manganese were at a moderate level; the content of available phosphorus, available potassium, total nitrogen, total potassium and exchangeable magnesium were at a rich level; the content of exchangeable calcium, available copper and available zinc content were at a very rich level; the content of total phosphorus was at an extremely rich level. The soil evaluation of Liuchu Town and Raoyang Town were good, the soil evaluation of Daguanting Town, Dayincun Town, Wangtongyue Town, and Wugong Town were moderate, and the soil evaluation of Dongliman Town was average. Liuchu Town and Raoyang Town should supplement nitrogen and control phosphorus and potassium appropriately, while reducing the amount of irrigation. Daguanting Town and Dayincun Town should supplement nitrogen and reduce irrigation water while reducing the use of copper containing fungicides. Wangtongyue Town and Wugong Town should reduce the input of potassium fertilizer. Dongliman Town should increase the application of organic fertilizers and reduce the input of potassium fertilizers. In summary, it can be seen that there is nitrate nitrogen leaching phenomenon and there is an enrichment phenomenon of available potassium in the soil surface layer. Therefore, it is recommended to the entire county should control water, supplement nitrogen, and reduce potassium appropriately, adjust phosphorus in the region, reduce the amount of calcium, magnesium, and zinc fertilizers used, and reduce the use of copper containing fungicides. |
