摘要
采用盆栽方法,研究了高分子保水材料(SAP,0、0.05、0.10、0.50 g/kg)、吸附性矿物材料(AM,0、5.0、10.0、15.0 g/kg)、煤基营养材料(CBN,0、0.5、1.0、1.5 g/kg)3种环境材料与化肥(CF,0、0.9、1.8、2.6 g/kg)、有机肥(OF,0、6、8、10 g/kg)配施对土壤含水率、速效氮含量、速效磷含量、脲酶活性、碱性磷酸酶活性及玉米产量的影响。结果表明,环境材料与肥料配施可以提高土壤含水率,其中吸附性矿物材料对其影响最大,最佳组合为SAP2CBN2AM4CF1OF3;可增加能够被植物直接吸收利用的速效氮含量,其中化肥对其影响最大,最佳组合为SAP2CBN2AM4CF4OF3;可增加能够被植物直接吸收利用的速效磷含量,其中有机肥对其影响最大,最佳组合为SAP1CBN4AM4CF4OF2;可提高土壤脲酶及碱性磷酸酶活性,其中有机肥对二者影响最大,最佳组合分别为SAP1CBN2AM2CF1OF4、SAP3CBN2AM2CF1OF4;可增加玉米籽粒产量,其中有机肥对其影响最大,最佳组合为SAP4CBN3AM2CF3OF4。综上,环境材料与肥料配施可增加土壤水肥,进而促进玉米增产。
Pot culture experiment was carried out to study the effect of three kinds of environmental mate-rial（water retaining polymer material（SAP,0,0.05,0.10,0.50 g/kg）,absorbent mineral materials （AM,0,5.0,10.0,15.0 g/kg）,coal-based nutrition materials（CBN,0,0.5,1.0,1.5 g/kg））and fer-tilizers（chemical fertilizer（CF,0,0.9,1.8,2.6 g/kg）,organic fertilizer（OF,0,6,8,10 g/kg）） on soil moisture content,available nitrogen content,available phosphorus content,urease activity,alkaline phos-phatase activity and maize yield.The results showed that the combined application of environmental mate-rials and fertilizers could improve soil moisture,and the adsorbent mineral material had the largest influence on soil moisture,the best combination was SAP2 CBN2 AM4 CF1 OF3;the combined application of environmen-tal materials and fertilizers could increase the available nitrogen content which could be directly absorbed＆amp;nbsp;and used by plants,and the chemical fertilizer had the largest influence on soil available nitrogen content , the best combination was SAP2 CBN2 AM4 CF4 OF3;the combined application of environmental materials and fertilizers could increase the available phosphorus content which could be directly absorbed and used by plants,and the organic fertilizer had the largest influence on soil available phosphorus content,the best combination was SAP1 CBN4 AM4 CF4 OF2;the combined application of environmental materials and fertiliz-ers could improve soil urease and alkaline phosphatase activities,and the organic fertilizer had the largest influence on both indexes,the best combinations were SAP1 CBN2 AM2 CF1 OF4 ,SAP3 CBN2 AM2 CF1 OF4 re-spectively;the combined application of environmental materials and fertilizers could increase maize yield, and the organic fertilizer had the largest influence on maize yield , the best combination was SAP4 CBN3 AM2 CF3 OF4 .In summary,the combined application of environmental materials and fertilizers could increase soil moisture and fertility,thus increasing maize yield.
