摘要
为研究不同有机肥部分替代化肥对生菜生长、品质及土壤酶和土壤微生物的影响,应用田间小区试验方法设置4个施肥处理:单施化肥(T1)、减量20%化肥+氨基酸生物有机肥(T2)、减量20%化肥+鸡粪(含花生枯腐殖酸)(T3)、减量20%化肥+炭基肥(T4).结果表明:T2处理增产提质效果最好,较T1处理显著增产20.62%,可溶性糖及维生素C含量分别提高17.14%和27.39%.此外,T2处理提高土壤酶活性25.86%~66.67%,T4处理提高土壤微生物数量4.42%~173.29%,但模糊综合评价结果显示T2处理综合肥效最好.因此,建议生菜种植采用氨基酸生物有机肥部分替代化肥的施肥方式.
In order to study the effects of partial replacement of chemical fertilizers by different organic fertilizers on growth and quality of lettuce,soil enzymes and soil microorganisms,four fertilization treatments,including chemical fertilizer(T1),20%reduced chemical fertilizer+amino acid bio-organic fertilizer(T2),20%reduced chemical fertilizer+chicken manure(with humic acid of peanut meal)(T3),and 20%reduced chemical fertilizer+carbon based fertilizer(T4)were set up by field plot experiment.The results showed that T2 treatment had the best effect of increasing the yield and quality of lettuce.Compared with T1 treatment,T2 treatment significantly increased yield by 20.62%,soluble sugar and vitamin C content by 17.14%and 27.39%,respectively.In addition,T2 treatment increased soil enzymatic activity by 25.86%~66.67%,T4 treatment increased soil microbial quantity by 4.42%~173.29%.The fuzzy comprehensive evaluation results showed that T2 treatment had the best comprehensive fertilizer efficiency.Therefore,it is suggested that amino acid bio-organic fertilizer should be used to partially replace chemical fertilizer in lettuce cultivation.
