Problems solved by technology

However, the existing technology is to put organic materials on the ridges where the plants grow, which has a large distribution space, and does not maximize the promotion effect of organic materials on root growth, does not isolate the root zone from the original soil, and cannot resist soil-borne diseases. occur

Embodiment 1

[0019] The preparation of embodiment 1 mycelia vegetative body

[0020] The preparation method of the mycelia vegetative body that the embodiment of the present invention provides, comprises the following steps:

[0021] S101: Preparation of compost: Mix 45-70 parts of corn cob, 20-40 parts of palm meal, and 10-15 parts of biomass packaging material additives; add 1.0-1.25 times the dry weight of the material to the compost Double tap water, mix well, adjust the water content in the culture material to 55%-60%, then put it into a sterilization bag, and sterilize it on the tunnel microwave sterilization equipment for 10 minutes-20 minutes.

[0022] S102: Pre-cultivation of strains: Inoculate the solid microbial strains into bacteria bags cooled to room temperature according to 5%-20% (w / w) of the wet weight of the culture material, mix well, tie the bags, and place them at a temperature of 25°C- Cultivate in a dark culture room at 30°C, 60%-70% ambient relative humidity, and w...

Embodiment 2

[0027] This example provides a method for transplanting mycelium vegetative body that optimizes the root system structure and promotes the growth of flue-cured tobacco roots. The basal fertilizer is applied around a position 15 cm deep from the ridge surface, the mycelial vegetative body is placed, and the tobacco seedlings are transplanted. Apply on the day of transplanting Raise seedling fertilizer, and carry out topdressing with water and fertilizer 30 days after planting; All fertilizers used are conventional fertilizers for flue-cured tobacco production in this area.

[0028] The specific technical implementation includes the following steps:

[0029] (1) After site preparation, ridging and ponding shall be carried out according to the standard row spacing;

[0030] (2) The base fertilizer is applied in the nest. After the pond is made, the organic fertilizer and the mixed chemical fertilizer are evenly spread in a circle at a position 15 cm deep from the ridge surface, a...

Embodiment 3

[0036] By adopting the method of the present invention, fertilizing and transplanting mycelium vegetative bodies of flue-cured tobacco were carried out in the farmland of Wazi Village, Pingdi Town, Renhe District, Panzhihua City, Sichuan Province, and conventional fertilization was set as a control group. The variety of flue-cured tobacco to be transplanted was Yunyan 97, and 1100 tobacco seedlings were transplanted per mu, with a row spacing of 120 cm and a plant spacing of 50 cm. 25d and 35d after transplanting, topdressing with water and fertilizer was completed.

[0037] In 2019 and 2020, field experiments in Pingdi Town, Renhe District, Panzhihua City, Sichuan Province showed that compared with farmers' customary fertilization, the humidity in the root zone of mycelial vegetative body increased by 20%-24%, and the root biomass at a distance of 15cm from the topsoil increased by 44.9% %, the root biomass at 20cm from the topsoil increased by 21.1%, the root biomass at 25cm...

Abstract

The invention discloses a method for transplanting tobacco seedlings by utilizing a hypha vegetative mass. The method comprises the following steps of preparing soil, applying base fertilizer, then placing the hypha vegetative mass which is soaked to be completely softened, filling the hypha vegetative mass with a matrix, transplanting the tobacco seedlings, covering the surface layer of the matrix with soil, immediately applying seedling lifting fertilizer after transplanting, and conducting topdressing 30 days after transplanting. The method can prevent infection of harmful bacteria, optimize the structure of a root system and promote growth of the flue-cured tobacco root system.

Description

technical field [0001] The invention belongs to the technical field of tobacco planting, and in particular relates to a method for transplanting tobacco seedlings using mycelium vegetative bodies. Background technique [0002] Tobacco is a high economic value hobby crop characterized by the synthesis of nicotine in the root system. A healthy root system is the basis of nicotine biosynthesis, and building a good root zone micro-ecology is the basis for healthy root growth. The root zone micro-ecology should not only provide good water, fertilizer, air, and heat environment for root growth, but also under field production conditions , but also to prevent harmful microorganisms in the soil from infecting the root system and causing soil-borne diseases, and such soil-borne diseases will cause fatal damage to the growth of tobacco, and the resulting loss exceeds 10% of the current year's income. [0003] In the prior art, the micro-ecological environment of the root zone can be ...
