【摘要】：为减少泥炭的开采和提高绿化废弃物的再利用率,探讨绿化废弃物好氧堆肥和蚯蚓堆肥替代泥炭作为蔬菜育苗基质的可行性,将好氧堆肥、蚯蚓堆肥、泥炭按不同体积混配制成6种基质:对照(泥炭),T1(好氧堆肥),T2(蚯蚓堆肥),T3[V(好氧堆肥)∶V(泥炭)=1∶1],T4[V(蚯蚓堆肥)∶V(泥炭)=1∶1],T5[V(好氧堆肥)∶V(蚯蚓堆肥)∶V(泥炭)=1∶1∶1],采用完全随机设计,对3种不同耐盐性蔬菜甘蓝Brassica oleracea(高耐盐性)、莴苣Lactuca sativa(中耐盐性)、西葫芦Cucurbita pepo var.ovifera(低耐盐性)进行育苗试验,重复10次·处理-1,研究不同基质的理化性质及其对蔬菜幼苗生长影响,并采用隶属函数评价各基质配方的优劣。结果表明:T4处理基质的理化性质的各项指标均在无土栽培基质的理想范围,甘蓝、莴苣和西葫芦幼苗在其中的生长质量综合评价指数分别为0.52,0.52,0.54高于对照0.33,0.49,0.49,成本较对照降低了41.56%,可用作甘蓝、莴苣和西葫芦育苗代用基质。
[Abstract]:In order to reduce the exploitation of peat and improve the reutilization rate of greening waste, the feasibility of replacing peat with aerobic compost and earthworm compost as vegetable seedling substrate was discussed. Aerobic composting and earthworm composting were carried out. Six substrates were prepared by mixing peat with different volumes: control (peat) T 1 (aerobic compost) T 2 (earthworm compost) T 3 [V (aerobic compost): v (peat) 1: 1] T4 [V (earthworm compost) V (peat) 1: 1] T5 [V (aerobic compost) V (earthworm compost)] V (earthworm compost) Peat) 1: 1: 1], in a completely random design, Three different salt-tolerant vegetables Brassica oleracea (high salt tolerance), lettuce Lactuca sativa (medium salt tolerance) and Cucurbita pepo var.ovifera (Cucurbita pepo var.ovifera) were cultured and treated for 10 times to study the physicochemical properties of different substrates and their effects on the growth of vegetable seedlings. Membership function was used to evaluate the quality of each matrix formulation. The results showed that the physicochemical properties of the substrate treated with 10% T4 were in the ideal range of soilless culture medium. The comprehensive evaluation index of the growth quality of lettuce and zucchini seedlings was 0.52n0.54, respectively, which was higher than that of the control 0.330.49. the cost of lettuce and zucchini seedlings was reduced by 41.56C, and could be used as substitute substrate for cabbage, lettuce and zucchini seedlings.
