preparation example Construction

[0029] The present invention also provides a method for preparing plant growth-promoting fungal metabolite dry powder, comprising:

[0030] The dry powder of the metabolite of Penicillium fungus, the dry powder of the metabolite of Penicillium restrictum and the dry powder of the metabolite of Penicillium rugosa are mixed to obtain the dry powder of the metabolite of the fungus.

[0031] In the present invention, preferably, the activated Penicillium funiculum, Penicillium limitiosa and Penicillium rugosa are respectively inoculated into the liquid culture medium, shaken and cultivated to obtain the Penicillium fungus metabolic bacteria liquid, the Penicillium limitum metabolic bacterial liquid and Penicillium rugosa Metabolizing bacteria liquid. In the present invention, there is no special limitation on the activation methods of Penicillium funiculum, Penicillium limitiosa and Penicillium rugosa, and conventional activation methods in the field can be used. In the present i...

Embodiment 1

[0045] Embodiment 1 (in the present embodiment, the activation of Penicillium fungus, Penicillium limitatum and Penicillium rugosa, each Penicillium of processes such as inoculation is carried out separately)

[0046] Prepare medium:

[0047] Cha's medium: 30.0g sucrose, NaNO 3 3.0g, MgSO 4 ·7H 2 O 0.5g, KCl 0.5g, FeSO 4 4H 2 O0.01g, K 2 HPO 4 1.0g, 1.0L distilled water, pH 7.0~7.2;

[0048] Malt extract medium: malt extract 20.0g, tap water 1.0L, natural pH.

[0049] The above-mentioned culture medium was sterilized at 121° C. for 20 minutes in an autoclave.

[0050] After the culture medium is cooled, scrape the colonies of Penicillium funiculum, Penicillium limitiosa and Penicillium rugosa respectively into a 250mL Erlenmeyer flask filled with 100mL sterile water, under the condition of 120r / min, Shake for 30 minutes to fully disperse the spore mass. The culture temperature of Penicillium funiculosa is 28°C, and the culture temperature of Penicillium limitatum and ...

Abstract

The invention belongs to the technical field of fertilizer preparation, and particularly relates to dry fungus metabolite powder and fertilizer for promoting plant growth, and preparation methods and application thereof. The dry fungus metabolite powder provided by the invention comprises 10-40 parts of dry penicillium funiculosum metabolite powder, 20-30 parts of dry penicillium restrictum metabolite powder and 10-40 parts of dry penicillium rugulosum metabolite powder. By compounding the dry powder of metabolites of penicillium funiculosum, penicillium restrictum and penicillium rugulosum, the growth of plants can be remarkably promoted;, for example, the plant height, stem circumference, leaf length and leaf width of the plants can be effectively improved, meanwhile, the effective ear number, thousand seed weight and the like of crops can be increased, and the effect of improving crop yield is achieved. Meanwhile, the dryfungus metabolite powder and the crop special fertilizer are applied in a combined mode, the effect of promoting plant growth and yield can be further enhanced, and economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a dry powder of fungal metabolites for promoting plant growth, fertilizer, a preparation method and an application thereof. Background technique [0002] Fertilizer is one of the important conditions to ensure high crop yield in agricultural production. For a long time, people's irrational use of chemical fertilizers has caused serious pollution of the air, water and other environments. And excessive use of single-efficiency fertilizers can easily cause soil acidification, decline in fertility, damage soil structure, and endanger soil health. In view of the above problems, the application of human and animal manure, straw and other organic fertilizers can solve the problems of soil acidification and fertility decline, but it is easy to cause pollution to the surrounding environment, and it is time-consuming and laborious. [0003] Microbial fertilizer...
