- 摘要:
- 以昌平区草莓主产区54个点位土壤样品为试材，选取了土壤pH、有机质、碱解氮、有效磷、速效钾、全氮、全磷、全钾8个指标作为评价依据，采用模糊评价法和综合描述相结合的方法，研究了昌平区草莓土壤单项养分指标和土壤肥力综合情况，并对土壤综合肥力情况进行评价，以期为昌平区草莓的肥料施用和管理提供参考依据。结果表明：研究区域内草莓大部分为碱性土壤，平均值为7.49；土壤有效磷、速效钾、全氮、全磷含量全部处于较高和高水平；有机质14.81%处于中等水平，85.19%处于较高及以上水平；土壤碱解氮16.67%处于中等水平，37.04%处于较高水平，46.30%处于高水平；土壤全钾59.26%处于中等水平，40.74%处于较高水平；土壤综合肥力指数一般地块占比2%；良好地块占比13%；优质地块占比85%。土壤的综合评价涉及水、肥、气、热等多种指标，未来可增加更多评价指标，完善评价模型。
- Abstract:
- Taking 54 soil samples from the main strawberry production areas in Changping district as the test materials,eight indicators，including soil pH，organic matter，available nitrogen，available phosphorus，available potassium，total nitrogen，total phosphorus and total potassium，were selected as the evaluation basis.By combining the fuzzy evaluation method and comprehensive description，the single nutrient index and the comprehensive soil fertility of strawberry soil in Changping district were studied，and the comprehensive soil fertility situation was evaluated,in oeder to provide reference for fertilizer application and management of strawberries in Changping District.The results showed that most of the strawberry soils in the study area were alkaline，with an average pH of 7.49.The contents of available phosphorus，available potassium，total nitrogen，and total phosphorus in the soil were all at high or very high levels.The organic matter content was 14.81%，which was at a medium level，and 85.19% was at a high or very high level.The available nitrogen content was 16.67% at a medium level，37.04% at a high level，and 46.30% at a very high level.The total potassium content was 59.26% at a medium level and 40.74% at a high level.The proportion of general soil fertility index plots was 2%，good plots was 13%，and high-quality plots was 85%.The comprehensive evaluation of soil involves multiple indicators such as water，fertilizer，air，and heat.In the future，more evaluation indicators can be added to improve the evaluation model.
