摘要
研究不同种植模式对连翘根系土壤理化性质的影响,对土壤肥力进行综合评价,以期为科学化指导生产,改善生态环境提供理论依据。试验在河北省石家庄市平山县连翘基地生态种植样地、露地栽培样地、野生样地进行,比较分析其土壤pH值、容重、有机质、全氮、全磷、全钾、碱解氮、有效磷及速效钾的含量。结果表明:采用生态种植模式的样地土壤有机质、全氮、全磷、碱解氮、有效磷及速效钾含量均高于野生和露地栽培模式,土壤pH值低于其他两种种植模式,野生样地土壤全钾含量高于生态种植及露地栽培样地。表明生态种植模式提高了土壤有机质含量,改善了土壤的酸碱度,增加了土壤养分含量,使当地土壤更适合连翘生长。综合分析认为:不同种植模式对0~20cm土层土壤养分影响较大。因此,生态种植能在一定程度上提升土壤养分,改善生态环境,利于连翘规模化生产。
The effects of different planting patterns on physical and chemical properties of Forsythia suspensa root soil were studied,and soil fertility was comprehensively evaluated,in order to provide theoretical basis for scientific production guidance and improvement of ecological environment.Soil with different planting patterns in Forsythia suspensa base in Pingshan County of Shijiazhuang,Hebei Province was studied in this experiment,and the contents of p H value,bulk density,organic matter,total nitrogen,total phosphorus,total potassium,alkali-hydrolyzed nitrogen,available phosphorus and available potassium were compared and analyzed.The results showed that the contents of organic matter,total nitrogen,total phosphorus,alkali-hydrolyzed nitrogen,available phosphorus and available potassium in the soil of the ecological planting pattern were higher than those of the wild and conventional open field cultivation patterns,and the p H value of the soil was reduced.The total potassium content of the wild plot was higher than that of the ecological planting and open field cultivation.The results showed that ecological planting increased soil organic matter content,improved soil p H,increased soil nutrient content,and made local soil more suitable for Forsythia suspensa growth.Comprehensive analysis showed that different planting patterns had a greater impact on soil nutrients in 0~20cm soil layer.In summary,ecological planting can enhance soil nutrients to a certain extent,improve the ecological environment,and facilitate the large-scale production of Forsythia suspensa.
