Preparation method and application of shell powder organic fertilizer biological conditioner

Abstract

A preparation method of a shell powder organic fertilizer biological conditioner comprises the following steps: A, preparing shell powder: cleaning shells with clear water, drying, soaking the cleanedand dried shells in a sodium hydroxide solution with the mass concentration of 0.2% for 40 minutes, cleaning again, and drying for later use; and then crushing; B, preparing an organic fertilizer: mixing pig manure compost with an amino acid organic fertilizer according to a weight ratio of 1: 1; and C, mixing: uniformly stirring and mixing the shell coarse micro powder obtained in the step A andthe organic fertilizer obtained in the step B according to a weight ratio of 1: 2 to prepare the shell powder organic fertilizer biological conditioner. The shell powder is combined with the organicfertilizer to replace an industrial fertilizer, the soil structure and physical properties can be improved, the water and fertilizer retention capacity of soil is improved, meanwhile, damaged soil microbial populations can be recovered, and the purposes of high yield, high quality, high efficiency and continuous land utilization of vegetable production are achieved.

Description

technical field [0001] The invention belongs to the technical field of soil conditioner preparation, and relates to a preparation method and application of a shell powder organic fertilizer biological conditioner, in particular to the application of the shell organic fertilizer biological conditioner in soil restoration in continuous cropping greenhouses. Background technique [0002] Greenhouse vegetable production is a vegetable production method that artificially creates a suitable living environment for vegetables when the temperature is not suitable. It is generally welcomed by people at home and abroad because it breaks the seasonal restrictions of vegetable production and makes the annual supply of vegetables balanced. It has the characteristics of being able to supply people's demand for vegetables in the off-season and high yield and high efficiency. Therefore, it is rising rapidly in the vast suburban areas in recent years, and has become a pillar industry in some a...

Problems solved by technology

However, vegetable greenhouse production is a land action mode that is strongly influenced by human beings. Human disturbance not only changes the microclimate environment for vegetable growth, but also affects soil properties.

At present, the problems in many greenhouses are soil compaction and secondary salinization, nitrate accumulation, soil nutrient imbalance, soil enzyme activity reduction, obvious soil acidification, microbial population damage, and enrichment of pesticide residues, etc.

At present, soil conditioner products on the domestic market generally use minerals such as potassium feldspar, limestone, phosphate rock powder, and food industry waste such as monosodium glutamate fermentation tail liquid as basic raw materials. Features such as low value
