Embodiment 1

[0034] A method for preparing a special matrix for safe seedling cultivation, the method comprising the steps of:

[0035] Step 1: preparation of fully fermented corn stalks;

[0036] (1) Dried corn stalks are crushed with a pulverizer and pre-treated with ammonia water;

[0037] (2) Choose organic cow dung or sheep dung without pesticide and heavy metal residues for use;

[0038] (3) Add active bacteria agent, Bacillus subtilis 20 billion / g, use 1 kg of biological bacteria per 1 cubic meter of treated straw, and distribute evenly;

[0039] (4) The proportion of raw materials is 2 parts of spare corn stalks and 1 part of spare organic manure. Spread a layer of bacteria evenly on every 20 cm of straw, add a layer of 10 cm of manure, spray water, and the overall water content reaches 60%-70%; spread another layer of straw, add another layer of bacteria, and then spread another layer Feces, and then sprayed with water, the height should be convenient for operation, and covered...

Embodiment 2

[0046] According to the method for preparing a special substrate for safe seedling raising described in Example 1, the specific process of pretreatment with ammonia water in the first step is: spray a layer of straw every 20 cm, spray evenly in mist, and seal and cover the stack with plastic cloth After 15-20 days, uncover the plastic sheet and reserve after 3 days.

Embodiment 3

[0048] According to the preparation method of the special substrate for safe seedling raising described in Example 1 or 2, the ratio of the raw materials in the step 4 is: fully fermented corn stalks account for 3 / 7 of the total, and fully fermented fruit and vegetable stalks account for 7 / 7 of the total Second, carbon ash accounts for one-seventh of the total, vermiculite accounts for one-seventh of the total, and fungicides account for three-thousandths.

Abstract

The invention discloses a preparation method of a safe seedling-raising special substrate. At present, straw fermentation mainly adopts composting modes such as composting in pit ponds and on lands, the compost can only be used as a single fertilizer after being fermented, the stability is poor, the physicochemical index is unstable, and the fermentation time is long. The method comprises the following steps: preparation of fully fermented corn straw, preparation of fully fermented fruit and vegetable straw, selection of a bactericide and carbon ash, and preparation of an overall seedling raising special substrate. The method is used for preparing the safe seedling-raising special substrate.

Description

Technical field: [0001] The invention relates to a method for preparing a special substrate for safe seedling cultivation. Background technique: [0002] At present, straw fermentation mainly adopts composting methods such as pit ponds and composting on land. After fermentation, compost can only be used as a single fertilizer, with poor stability, unstable physical and chemical indicators, and long fermentation time. Invention content: [0003] The purpose of the invention is to provide a method for preparing a special substrate for safe seedling cultivation. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] A method for preparing a special matrix for safe seedling cultivation, the method comprising the steps of: [0006] Step 1: preparation of fully fermented corn stalks; [0007] (1) Dried corn stalks are crushed with a pulverizer and pre-treated with ammonia water; [0008] (2) Choose organic cow dung or sheep dung without pesticide a...
