Special substrate for preserved vegetable seedling raising

Abstract

The invention provides a special substrate for preserved vegetable seedling raising, and belongs to the technical field of plant fertilizer manufacturing. The special substrate is prepared from livestock manure, sawdust, grain husks and plant ash, and further comprises vegetable leaf residues and a traditional Chinese medicine substrate. The vegetable leaf residues are composted in the steps that the vegetable leaf residues are piled, sprayed with clean water, covered with thin films and fermented, the thin films are removed, the vegetable leaf residues are spread and ventilation to be naturally dried, and then the vegetable leaf residues are smashed and screened. Chinese herbal medicine is processed in the steps that herba houttuyniae, chinese prickly ash, chinaberry bark, garlic, angled bittersweet, root of Rhamnus crenata Sieb.et Zucc., fructus quisqualis, rhubarb and folium eucalypti are steamed without making contact with water, then the materials are put into a stirrer to be smashed into paste, and the required traditional Chinese medicine substrate is obtained. Good fertilizer efficiency can be achieved, the traditional Chinese medicine substrate can kill bacteria and dispel insects in the preserved vegetable seedling raising process, and harmful bacteria or pest invasion on preserved vegetables is reduced or avoided; meanwhile, the special substrate is simple in manufacturing process, high in fertilizer efficiency and capable of effectively increasing economic benefits of farmers.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of plant fertilizer production, in particular to a special substrate for raising plum vegetable seedlings. [0003] 【Background technique】 [0004] Meicai is a special product in Huizhou, Guangdong. Meicai and mustard greens belong to the same species and have similar shapes. Because of their strict requirements on the climate, they are generally only planted in autumn and winter. , is one of the few vegetable varieties in China.

Problems solved by technology

This patent is mainly to solve the problem of cumbersome preparation of nutrient solution and high cost caused by the lack of nutrients in the substrate under the condition of seedling cultivation.

[0007] Using conventional seedling and cultivation substrates such as peat, perlite, and vermiculite, the nutrient content is low, and nutrient solution must be poured. Not only is the cost high, but the pollution to vegetables is also high, especially some nitrogen elements will be high
