Embodiment 1

[0019] Embodiment 1 AM fungus propagation

[0020] (a) Propagation substrate preparation: premix peat soil, field soil, and river sand according to 2:2:1 (volume ratio), and use polyethylene bags (1kg / bag). The physical and chemical properties of the propagation substrate are listed in Table 1. Group VI is shown.

[0021] (b) Sterilization: Put the packed sterilization bag into the sterilization pot, keep it at 121°C for more than 6 hours, and sterilize the culture container (or flower pot) with formaldehyde for 24 hours.

[0022] (c) Inoculation: after filling about 1 / 5 of the matrix at the bottom of the culture container, start to spread the AM fungus Glomus mosei inoculum layer by layer at intervals of 1 to 5 cm matrix (the inoculation amount is 10g / kg matrix), Up to 4 / 5 of the volume of the culture container, wash hands before inoculation.

[0023] (d) Sowing: the host Sorbus dandelion seeds are sterilized and washed 3 times with distilled water. After germination in a 2...

Embodiment 2

[0026] Embodiment 2 AM fungal fertilizer production method

[0027] Material: peat soil, field soil, river sand, humus (50% (volume) of fungus chaff and 50% (volume) of cow dung); the raw material of fungus chaff is common mushroom residue, and cow dung is common cow manure after decomposing use.

[0028] (a) Sterilization: Peat soil, field soil, river sand, and humus must be sterilized by dry heat at a high temperature of 121°C for more than 6 hours after mixing.

[0029] (b) Preparation of bacterial manure: In a well-drained field, fumigate with 95% formaldehyde solution to sterilize the surface soil, then turn the field soil down 40-50 cm, add peat soil and river sand in the field (or flowerpot) (by peat soil, field soil, river sand volume ratio is 2: 2: 1 ratio), the inoculant (the inoculant is 1 / 3 of matrix volume) that step (1) is made is sprinkled in the soil, and simultaneously Sow the seeds of clover, sundanese and tobacco (the planting ratio of clover, sundanese an...

Embodiment 3

[0030] Embodiment 3 Tobacco AM fungal bacterial fertilizer using method

[0031] (a) Inoculation: the bacterial fertilizer and the special matrix of tobacco in the pseudo-planting period (every 666.7m 2 Carry out retting according to the ratio of 20kg crushed wheat straw, 10kg ring manure and 10kg topsoil) in a ratio of 1:2 (volume ratio) for mixed use.

[0032] (b) Management: According to the conventional management of tobacco, special chemical fertilizers for tobacco (produced by Suihua Longfu Fertilizer Co., Ltd.) are applied.

[0033] Table 3 Effects of AM fungal fertilizer on the yield and K content of tobacco treated with full fertilizer and half fertilizer

[0034]

[0035] The result is as Figure 1-3 As shown in Table 3 (full fertilizer), the results show that: AM fungal fertilizer can reduce the susceptibility rate of leaves, advance the flowering time of tobacco, and increase the number of lateral roots in the root system. Under normal fertilizer and water ma...

Abstract

The invention discloses a simple protection technology of special AM (arbuscular mycorrhiza) fungal manure for tobacco. The simple production technology comprises the steps of propagating Glomus mosseae as an AM fungus which in good interaction with tobacco by pot culture to obtain an inoculant; further expanding the production in the field to obtain a fine granular mixture rich in fungal spore, hypha, substrate and plant root; drying the mixture in the air; and then adding humus with the same volume to uniformly mix to obtain special AM fungal manure for the tobacco. The fungal manure not only can promote the growth of tobacco plants, improve the quality of tobacco leaves, reduce and relieve plant diseases, but also can fully utilize the nutritional ingredients. According to the production technology disclosed by the invention, the fungal manure can increase acre yield by 25-30% and potassium content in the lower-middle tobacco leaves by 4-5% under normal nutrient and water management condition. When nitrogen and phosphorus fertilizer amount is reduced by half, the fungal manure can increase acre yield by 15-20% and potassium content in the lower-middle tobacco leaves by more than 5%. As a result, the use amount of special manure for the tobacco can be reduced.

Description

technical field [0001] The invention relates to a production process of AM fungus fertilizer products, in particular to a production process of AM fungus fertilizer capable of promoting the growth of tobacco, improving the quality of tobacco leaves, reducing and alleviating plant diseases, and reducing the amount of chemical fertilizer used. Background technique [0002] Microbial fertilizers, also known as inoculants, biological fertilizers, bacterial fertilizers, etc., refer to products containing specific living microorganisms. It is used in agricultural production to increase the supply of plant nutrients or promote plant growth, increase yield, improve the quality of agricultural products and the agricultural ecological environment through the life activities of microorganisms contained in it. At present, the microbial fertilizer in my country is mainly in the form of rhizobia and other microbial fertilizers, and Arbuscular mycorrhiza (AM) fungi are used as a kind of ba...
