Effects Of Mushroom Residue And Different Kinds Of Fertilizers On Greenhouse Soil Physical And Chemical Properties And Growth Of Leafy Vegetables

At present, Chinese agricultural production has produced a large amount of organic waste per year. Agricultural resources development and utilization rate of waste is still low. China has become the world’s largest producer of edible fungi. The cultivation of material per 100 kg will produce 100 kg harvest mushroom and it will produce 60 kg of mushroom compost waste. These wastes are kept misplacing chaos not only pollute the environment, but also create resources waste. In greenhouses, excessive use of chemical fertilizers in recent years leding to deterioration of soil physical and chemical and biological properties of the disease occur frequently. These problems seriously affect the food security of high yield and quality of vegetables and vegetable basket project, which restricts the production Vegetables and social benefits.This paper studies two aspects: First, to study the processing of spent mushroom compost into the soil in different proportions on soil properties and three leafy vegetables(lettuce, rape, cabbage, etc.) the growth and development of two different types of leek quality, growth and the impact of soil fertilizer. The purpose is to explore the application of different types of mushroom compost and fertilizer on soil properties and leafy growth and development, quality of product, as mushroom compost, different kinds of fertilizer application in vegetable cultivation provide theoretical and technical basis. Pot test mode, the main research results are as follows:(1) Administering treatment of spent mushroom compost reduced soil bulk density values and increased soil porosity and water-holding capacity. It controled(CK1) were significantly different. With the increase of mushroom compost application rate, bulk density progressively decreased values. Treatment 1/4 mushroom compost +3/4 soil, 1/3 mushroom compost + 1/3 soil, 1/2 mushroom compost + 1/2 soil, 3/4 mushroom compost +1/4 soil compared with the control(CK1) improved 9.10%, 18.55%, 26.11%, 46.76%. The difference between treatments significantly improved the administration of mushroom compost soil porosity water, gas and heat condition.(2) Administering treatment of mushroom compost increased soil organic matter, total nitrogen, phosphorus, potassium content effectively, which 3/4mushroom compost +1/4 soil treatment and control(CK1) of total nitrogen, phosphorus and effective potassium content increased by 2.39 times, 3.48 times and 34.37 times. It had a significant difference between the administration of each treatment.With the increasing amount of mushroom administration, there are clear differences.(3) The application of mushroom compost treatment significantly increased enzyme activity in the soil, where 3/4 mushroom compost+1/4 soil treatment Catalase activity than the control(CK1) improved 3.31 times, Invertase activity increased 3.18 times, Urease activity increased the 10.95 times and neutral Phosphatase activity improved 7.54 times.(4) Mushroom compost processing slag favor leafy growth and improved the quality of its leafy lettuce yield. Treatment 1/2 mushroom compost +1/2 soil was compared with the control(CK1) improved 411.66%, 1/2 mushroom compost +1/2 soil treatment compared with the control(CK2) improved 261.19% and3/4 mushroom compost +1/4 soil treatment compared with the control(CK3) improved 365.27%. They had a significant differences. Administration of each treatment of mushroom growth of three leafy vegetables(lettuce, rape, cabbage) in nitrate content was significantly lower than the control treatment, which WT4, YT4,NT4 nitrate content in leafy vegetables processing was compared with the control treatment reduced by 54.87%, 52.97%, 52.31%.(5) Although the application of different kinds of fertilizer can promote the growth of leek and increase production. Leek nitrate content was difference between different fertilizer treatments significantly. Compound fertilizer(F3), controlled-release fertilizer(F4) grown leeks nitrate content than the control(no fertilizer) improved 12.48% and 9.87%, while the application of organic manure(F5) and bio-organic fertilizer(F6) leeks grown nitrate content compared with the control(no fertilizer) decreased 46.97%, and 47.38%. From the index reflectde the nitrate content of fertilization and leeks quality.
