以第一代猪发酵床废弃垫料基质(WD)为主要原料，通过添加蛭石和醋糟中的一种或两种进行基质配比，测定了不同复配基质的理化性质(容重、总孔隙度、水气比、pH、EC、全氮、碱解氮、有机质等)，研究了不同基质对辣椒的植株生长、光合作用、产量及果实品质的影响。结果表明：T8处理(WD︰醋糟︰蛭石=9︰2︰6)的物理性质均在理想基质范围内；T7(WD︰醋糟︰蛭石=9︰4︰4)、T8、和T9(WD︰蛭石=9︰5)处理的全氮、碱解氮、速效钾含量较低，全磷、速效磷含量较高，pH较高，EC值较低；T7、T8和T9处理的辣椒植株株高、茎粗显著高于其他的处理；T8处理的辣椒叶片光合作用最强，叶绿素含量最高，且显著高于CK；T8处理的辣椒植株产量最高，其次为T4(WD︰蛭石=5︰2)处理，T4、T8处理分别较CK产量提高7.74%、11.14%；T7和T8处理辣椒的可溶性固形物含量相对较低，但其Vc、可溶性蛋白和可溶性糖含量相对较高。综合考虑，生产上推荐使用T8处理作为辣椒生长的有机栽培基质。

TThe 1st generation of waste padding of pig fermentation bed (WD) was used as the main material, added with vermiculite or vinegar residue or their mixture to prepare the compound substrates with different formulas. Then physicochemical properties (unit weight, total porosity, water/air ratio, pH, EC, total nitrogen, alkali-hydrolyzale nitrogen, organic matter, etc.) of these substrates and their effects on plant growth, photosynthesis, yield and fruit quality of peppers were studied. The results showed that physical characteristics of T8 treatment (WD︰vinegar residue︰vermiculite = 9︰2︰6 ) were all within the ranges of ideal substrate. T7 (WD : vinegar residue︰vermiculite = 9︰4︰4), T8, and T9 (WD︰vermiculite = 9︰5) treatments had lower total nitrogen, available nitrogen, available potassium contents and EC values, but had higher total phosphorus, available phosphorus contents and PH values. The plant heights and stem diameters of pepper of T7, T8 and T9 treatments were significantly higher than those of other treatments. T8 treatment had the highest photosynthesis and chlorophyll content, significantly higher than those of CK. T8 had the highest pepper yield, followed by T4 (WD︰vinegar residue = 5︰2), increased by 11.14% and 7.74%, respectively, compared with CK. T7 and T8 treatments had lower soluble solids contents, but higher contents of Vc, soluble protein and soluble sugar. On the whole, T8 treatment is recommended as an organic substrate for the growth of pepper.
