Soil remediation fertilizer for strawberry in greenhouse and preparation method thereof

Abstract

The invention discloses a soil remediation fertilizer for strawberry in a greenhouse and a preparation method thereof. The soil remediation fertilizer is characterized by being prepared from the following components in parts by mass: 20-30 parts of biological carbon, 2-4 parts of EM bactericide, 30-40 parts of organic fertilizer, 10-15 parts of crop stalks, 4-6 parts of calcium superphosphate, 4-6 parts of potassium chloride, 1-2 parts of zinc sulfate, 1-2 parts of ferrous sulfate, 6-8 parts of natural mineral powder and a moderate amount of water. The invention provides the soil remediation fertilizer which can solve the problem on continuous cropping soil for the strawberry in the greenhouse; and problems on salt accumulation, acidification, soil hardening, nutrient imbalance, microecology dysbiosis and the like present in the continuous cropping soil for the strawberry are solved effectively.

Description

technical field [0001] The invention relates to a soil repair fertilizer for greenhouse strawberries and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Strawberry is a common fruit in my country. It should be grown in fertile loam soil with good light, rich organic matter, strong water retention, good air permeability, neutral or slightly acidic. It is often cultivated in greenhouses in winter. Planting strawberries year after year will easily form continuous cropping obstacles, leading to soil fertility decline. The soil microbial flora deteriorates, and soil-borne diseases occur seriously. At the same time, because strawberry is a shallow-rooted crop, it absorbs more nutrients in the topsoil layer during the growth process, and has selective absorption of various nutrients, resulting in soil nutrient imbalance. , Salt accumulation, organic matter content decline, soil compaction, resulting in poor plant growth, yi...

Problems solved by technology

[0002] Strawberry is a common fruit in my country. It should be grown in fertile loam soil with good light, rich organic matter, strong water retention, good air permeability, neutral or slightly acidic. It is often cultivated in greenhouses in winter. Planting strawberries year after year will easily form continuous cropping obstacles, leading to soil fertility decline. The soil microbial flora deteriorates, and soil-borne diseases occur seriously. At the same time, because strawberry is a shallow-rooted crop, it absorbs more nutrients in the topsoil layer during the growth process, and has selective absorption of various nutrients, resulting in soil nutrient imbalance. , Salt accumulation, organic matter content decline, soil compaction, resulting in poor plant growth and development, yield and quality decline, so it is very important to find a measure that can alleviate the obstacles of strawberry continuous cropping
