用于市政工程绿化种植土壤的营养材料及制备方法及应用 技术领域
本发明涉及及市政工程绿化和园林绿化技术领域技术领域，尤其涉及一种用于市政工程绿化种植土壤的营养材料，还涉及其制备方法及应用。
背景技术
园林绿化工程是建设风景园林绿地的工程。园林绿化是为人们提供一个良好的休息、文化娱乐、亲近大自然、满足人们回归自然愿望的场所，是保护生态环境、改善城市生活环境的重要措施。园林绿化泛指园林城市绿地和风景名胜区中涵盖园林建筑工程在内的环境建设工程，包括园林建筑工程、土方工程、园林筑山工程、园林理水工程、园林铺地工程、绿化工程等，它是应用工程技术来表现园林艺术，使地面上的工程构筑物和园林景观融为一体。社会经济的不断发展，人民生活水平日益提高，“绿色健康”理念深入人心。人们的环境意识越渐增强，市政园林绿化工程得到前所未有的关注。绿化事业发展迅速，呈现一片蓬勃之势。但是在园林绿化建设繁荣发展的同时，市政园林绿化工程施工管理中存在的问题也日益突出。其中，由于市政绿化工程以及园林绿化场所的人流量大，绿化的破坏率高以及产生的废弃物已经成为该绿化工程中存在的最重要也是最棘手的问题。
绿化植物的营养基质最为植物生长的基础，在绿化工程中具有重要的作用，现有技术中通过对营养基质的改善能够显著改善绿化的效果。如中国专利申请CN103304302A即公开了一种用于垂直绿化、立体绿化和屋顶绿化的营养基质，此营养基质不仅可以减轻屋顶和立体绿化营养钵的承载重量，还可以为植物生长提供养分。保障了植物在屋顶和立体营养钵的特殊环境下可以正常生长。但是该技术方案使用的原料大多为工业废物，虽然在一定程度上能够有效处理和消纳工业废弃物，但是其带来的营养物质和矿物质远远不够绿化植物的生长的营养所需。再例如中国专利CN103553807A公开了一种用于市政工程绿化和园林绿化的营养材料及其制备方法，由如下重量份数的组分组成：土20-30份，泥炭土20-30份，固氮菌群5-10份，有机物分解菌群3-5份，纤维骨架5-10份；珍珠岩10-30份，蛭石10-30份，绿色木霉菌3-5份。制备方法主要为将处方量的土壤、泥炭 土、纤维骨架、珍珠岩、蛭石混合均匀，再加入处方量的有机物分解菌群菌体，固氮菌群菌体以及绿色木霉菌菌体即可得到本发明的营养材料。该技术方案明营养材料能够大幅度提高绿化土壤的持续营养能力，更能在植物生长过程中消化吸收部分固体废弃物，从而改善市政绿化工程和园林工程的景观。但是该技术方案中的营养物质带来的土壤，不能根据土壤的变化进行自我酸碱度调节调节，因为如土壤自身的酸碱度严重偏差时，导致植物无法生存甚至营养材料本身不能发挥作用，无法起到改善市政绿化工程和园林工程的景观的作用。且该技术方案中的营养材料无法改善土壤的疏松度，对其他添加的营养物质也没有表现良好的相容性和友好的特点。
因此，研究一种用于市政工程绿化和园林绿化的营养材料以改善现有的市政工程绿化效果是非常必要。

实施例8
在实施例1～7的基础上，本实施例提供一种用于市政工程绿化种植土壤的营养材料的制备方法，具体步骤如下：
(1)分别使用合适的培养基培养各实施例1～7中的微生物菌群：培养时间:根据特定菌群的要求进行调整、培养；完成后浓缩离心后，得有机物分解菌群菌体，固氮菌群菌体以及绿色木霉菌菌体；
(2)实施例1～7中的营养液的制备：加入需量的水后，依次加入配量比的N、固体P2O5、固体K2O、有机质和基质之后，搅拌2～3h成均匀浆体，静置4h， 使其固液沉淀分离，抽滤其液体，即为营养液；
(3)将步骤(2)中制备的营养液按照配量比加入到相应配量比的土壤、泥炭土、纤维骨架和腐植酸中混合均匀，再加入步骤(1)中培养的有机物分解菌群菌体，固氮菌群菌体以及绿色木霉菌菌体，得到所需的营养材料。
试验：
采用本实施例7所述土壤的营养材料与普通土壤1:4混合作为植物生长基质。
取样与分析：采取5点取样法取土，混合均匀，过筛处理，土壤样品PH值的测定采用2.5:1.0水浸提电位法，有机质(OM)含量的测定采用高锰酸钾容量法，有效氮(AN)的测定采用碱解扩散法，有效磷(AP)含量的测定采用Olsen法，有效钾(AK)含量的测定采用乙酸铵浸提火焰光度法，全氮(TN)含量的测定采用半微量凯式定氮法，全磷(TP)含量的测定采用钼锑抗比色法，缓效钾(SK)含量的测定采用火焰光度法。
数据处理：数据整理使用Excel2007，数据计算使用SPSSl7.0。数据标准化应用Analyze---Descriptive Statistics----DescriptiVOS，相关系数矩阵、特征值和特征向量、主成分得分的计算应用Analyze_Data Reduction_Factor Analysis。
根据以上所确定的主成分分析法测定土壤肥力的实验，分别取不同时间段内岩坡内土壤样品的上述4个指标。本实施例中的取样时间为每隔6个月，取样方法为网格布点法，每500m取1个点，如遇到障碍物则就近取样。采取5点取样法取土，混合均匀，过筛处理等。各次取样样本的指标取其平均值，以x±s的方式表示。各取样时间样本指标测定结果如下表所示：
取样时间 TN(g/kg) TP(g/kg) OM(g/kg) AP(g/kg)
0个月 1.25±0.21 0.30±0.15 19.20±6.59 9.78±2.55
6个月 1.42±0.23 0.33±0.15 25.21±5.34 10.33±2.01
12个月 1.78±0.25 0.42±0.16 38.25±7.30 12.28±2.25
18个月 2.08±0.31 0.56±0.18 40.67±6.35 12.98±2.36
24个月 2.58±0.34 0.66±0.18 46.28±6.54 16.58±2.76
30个月 2.69±0.35 0.78±0.19 65.65±8.70 18.24±2.69
由上表可以看出，采用本发明所述的营养材料后0-30个月内，影响土壤肥 力的四个主要指标均逐步改善，其中第30个月的土壤肥力各指标与施用本发明土壤改良方法前的土壤各指标具有显著性差异，提示本发明所述的营养材料可以显著提高土壤的肥力，并使植物的生长与土质的改善能够相辅相成。能根据土壤的变化进行自我酸碱度调节调节，改善如土壤自身的酸碱度严重偏差时，导致植物无法生存甚至营养材料本身不能发挥作用，无法起到改善市政绿化工程和园林工程的景观的作用的状况。且本实施例的营养材料对于改善土壤的疏松度也具有很大的效果，对其他添加的营养物质表现良好的相容性和友好的特点。
采用实施例1、实施例2、实施例3、实施例4、实施例5以及实施例6所述的营养材料与普通土壤混合后，均可取得与上述实验相似的土壤肥力改善效果。
上述说明示出并描述了本发明的优选实施例，如前所述，应当理解本发明并非局限于本文所披露的形式，不应看作是对其他实施例的排除，而可用于各种其他组合、修改和环境，并能够在本文所述发明构想范围内，通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本发明的精神和范围，则都应在本发明所附权利要求的保护范围内。
