Abstract

The invention discloses a seedling growing method capable of improving disease resistance. The seedling growing method comprises the following steps that rice straw, corn straw and pine branches are burned to obtain ash, then sand and clay are added, even mixing is carried out, and granulating is carried out to obtain pre-made seedling soil; sodium carboxymethylcellulose, microcrystalline cellulose, vegetable oil and water are stirred evenly, anhydrous ethanol and sepiolite are added, and even stirring is carried out to obtain a binder; the pre-made seedling soil is rolled and preheated to 50-60 DEG C, then the binder is sprayed onto the surfaces of particles of the pre-prepared seedling soil, even stirring is carried out, drying is carried out at 100-110 DEG C until the water content is 4-10wt%, and composite seedling soil is obtained; the robust branches are cut into cuttings with 2-3 axillary buds, the upper ends of the cuttings are cut flat, the lower ends of the cuttings are cut to 45 degrees, then lower end cuts are soaked with clear water, and then the lower end cuts are soaked in a rooting agent after disinfected; and the treated cuttings are vertically stuck in the composite seedling soil for planting cultivation, the environment temperature is 20-24 DEG C, the environmental humidity is 65-70%, and the seedlings are taken out of a nursery.

Description

technical field [0001] The invention relates to the technical field of seedling cultivation, in particular to a seedling cultivation method capable of improving disease resistance. Background technique [0002] At present, the propagation methods of seedlings are mainly divided into seed propagation and cutting propagation. The seed propagation method is simple, but the seed germination rate is low. The method of cutting propagation is to select a plant that grows robustly and is free from diseases and insect pests, cut off its root or reed head, soak it with plant hormones, insert it in sandy soil, water it at the right time, and transplant it after a period of cultivation. Among them, the seedling substrate is used in modern agriculture and forestry to replace soil for cutting propagation and seedling cultivation. Since the seedling substrate is easier to control the nutrient content and realize large-scale production than ordinary soil, it has gradually been widely used....
