Soilless culture substrate for lettuce and preparation method and device

Abstract

The invention relates to the technical field of soilless culture substrates, in particular to a lettuce soilless culture substrate and a preparation method and device.The preparation method comprises the following steps that rice husks, saw dust and mushroom residues are smashed and then put into a fermentation tank together with pig manure, vermiculite and humic acid to be fermented, and a fermented product is obtained; soaking clove, ginkgo leaves, ginger and perilla frutescens in warm water, filtering out a soak solution, boiling the first filter residues in water, uniformly mixing the filtered liquid with the soak solution to obtain a mixed solution, drying the second filter residues in the sun, and grinding the dried second filter residues into powdery particles; uniformly mixing the powdery particles with the fermentation product, and putting the mixture into a fermentation tank for secondary fermentation; stirring and mixing the secondary fermentation product and the mixed solution to obtain a mixed material; the device comprises a production mixing structure and a matched production structure, and the side end position of the production mixing structure communicates with the matched production structure; the fertilizer has the advantages of wide raw material source, simple production process, great reduction of the cultivation cost, rich nutrient content and long fertilizer efficiency.

Description

A kind of lettuce soilless culture substrate and preparation method and device technical field The present invention relates to soilless culture substrate technical field, be specially a kind of lettuce soilless culture substrate and preparation method and device. Background technique Cultivation substrate originally originates from the concept of soilless culture, refers to that the soil environment around crops has deteriorated, seriously affecting the soil environment. The yield and quality of crops have been affected, and people have turned to look for alternatives, fixing plant roots with solid substrates (mediums), and Substance absorbs nutrients and oxygen. According to Chinese patent number CN202011531455.8, the present invention relates to a kind of cultivation substrate container production line, comprising A substrate feeding mechanism for supplying a cultivation substrate, a cultivation substrate distributing unit for dividing the cultivation substrate,...

AI Technical Summary

Problems solved by technology

In addition, the layout of the whole production line is reasonable, the production runs smoothly, the elimination of indoor dust noise is considered to reduce pollution, and the recycling of scattered cultivation substrates is also considered to avoid production waste. However, the patent cannot realize feeding and mixing. , Production of integrated production process, needs to be improved

[0006] However, there are still some deficiencies in the use of the existing soilless culture substrates. In the process of use, the integrated production process of feeding, mixing and production cannot be realized, which is not conducive to industrialized production work, and it is inconvenient to carry out Repeated mixing production work, so a preparation device for lettuce soilless culture substrate is needed to solve the problems mentioned above
