With the expanding area of soilless culture throughout the world and unceaseing improvement in technology of soilless culture in recent years, finding some new substrates as peat moss substitute has been put in the research interest among many scholars. Despite its proved excellent characteristics and far-flung presence, peat moss is a finite and unreproducibler resource, therefore, exploiture on a large scale could lead to a destructive destroy of ecological environment. Aiming to reducing possible destruction, the study introduce mushroom residue, a fermented agricultural offal, to conduct research and popularization in vegetable culture.The results are as follows:1. The organic substrate of mushroom residue was produced from fermented residue of spent mushroom. We add 0.2kg microbe for fermentation(Baicheng biological bacterium),0.5kg urea and 3kg sesame dreg or chicken manure in 1m~3 spent mushroom residue. The optimal temperature for fermentation is between 50℃ and 60℃, the best water content in fermented mixture is 50-60% and the finest effect of fermentation was seen at 20-60cm below the top of the compost. Three months was thought a proper time span for fermentation.2. The admixture are as follows(V:V):mushroom residue: perlite (4:1,3:1,2:1, 1:1,1:2), mushroom residue: vermiculate(6:1,5:1,4:1,3:1,2:1), mushroom residue: vermiculate: perlite (2:1:1,1:1:1). The physical and chemical characteristics of mushroom residue need improving even after complete fermentation, demonstrated by its crude appearance, high EC value. We selected perlite and vermiculite, mostly widely-used substrate, as a component of admixture for the sake of facilitation in production. We explore the proper proportion of each substrate in compound substrate by measuring physical and chemical characteristics of each single substrate. Tomato, sweet pepper and cucumber nursery was conducted with different component of compound substrate and water irrigation, and sweet pepper cultivation was carried out subsequently with water and nutrition irrigation in compound substrate of different component. The results demonstrated that the admixture of...
