Preparation method of disease-resistant vegetable seedling-raising substrate

Abstract

The invention discloses a preparation method of a disease-resistant vegetable seedling-raising substrate. The method comprises the steps of: (1) taking an organic raw material, animal manure, sludge, biological bacterial fertilizer powder and other ingredients as the fermentation raw materials for standby use; (2) diluting a fermentation agent; (3) stirring the fermentation materials and the fermentation agent diluent for 10-20min to obtain an organic matrix; (4) mixing the organic matrix, sand and slag evenly, and performing drying and crushing to obtain a seedling-raising substrate semi-finished product; (5) mixing a proper amount of urea, monoammonium phosphate, the seedling-raising substrate semi-finished product, a stem strengthening agent, quintozene powder, a zineb agent, quick lime, fenaminosulf, DDVP and other components, thus obtaining the product. The method provided by the invention takes various industrial and agricultural waste and municipal refuse as the raw materials, and fully realizes utilization of waste materials. The prepared seedling-raising substrate not only is safe and environment-friendly, but also has the effects of: a. fixation and support; b. water and fertilizer retention; c. ventilation; d. buffering; e. nutrient supply; and f. pest control.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for preparing a disease-resistant vegetable seedling-raising substrate. Background technique [0002] At present, the widely used seedling substrates are made of various peat and peat as the main components, adding vermiculite, perlite, rice bran, polystyrene, calcined soil and mineral soil, etc. This kind of substrate is relatively resource-consuming There are many types. In the actual use of this mixed substrate, it not only increases the cost of production, but also cannot prevent and control common diseases in the process of vegetable seedling cultivation. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a method for preparing a disease-resistant vegetable seedling-raising substrate. The operating steps of the present invention are as follows: [0004] (1) Take 50-60 parts of o...
