Problems solved by technology

[0004] The production of green vegetables has strict production management standards, among which there are clear restrictions and regulations on the use of pesticides. Modern agriculture generally has a high degree of production intensification and a high multiple cropping index, long-term continuous cropping methods and some improper cultivation methods, resulting in The composition of soil harmful microorganisms and soil animals is developing in a bad direction, and pests and diseases occur frequently, spread rapidly, and increase year by year

Embodiment 1

[0029] Embodiment 1 Preparation of special-effect microbial bacterial powder

[0030] 1. Strain preparation and activation

[0031] Bacillus amyloliquefaciens was inoculated on a solid beef extract medium plate and cultured at 30°C for 48h. The formula of beef extract solid medium used is: beef extract 2g / L, glucose 4g / L, peptone 10g / L, sodium chloride 5g / L, agar powder 15g / L, pH=7.2-7.4, sterilized at 121°C for 20 minute.

[0032] Inoculate Trichoderma chrysogenum on potato dextrose medium and culture at 25°C for 48h. The formula of the potato glucose medium used is: potato 20g / L, glucose 20g / L, agar powder 15g / L, wash and peel the potato and cut into small pieces, add water to boil and filter with 2 layers of gauze, add to the filtrate Dextrose and agar powder, sterilized at 121°C for 20 minutes.

Embodiment 2

[0039] Example 2 The preparation method of special bio-organic fertilizer for iron-rich green vegetables

[0040] 1. Remove the edible fungus waste residue from the packaging bag, dry it, and grind it to 200 meshes after drying, and set it aside.

[0041] 2. Mix 150kg of humic acid and 50kg of rapeseed meal with 750kg of the above-mentioned crushed edible mushroom waste residue, and adjust the water content to about 50%.

[0042] 3. Add 0.2% conventional organic material starter by weight of the mixture to the above mixture to ferment. The mixture was stacked 1 meter high, and bioaerobic solid fermentation was carried out for 7 days at normal temperature. During the fermentation process, the fermentation temperature is well controlled, and when the temperature reaches 50-70°C, turn over the pile. Then carry out the second fermentation, turning and throwing once every 3 days until it is completely decomposed, and the second fermentation time is 15 days.

[0046] Example 3 Field Fertilizer Effect Test of Iron-rich Green Vegetable Special Biological Organic Fertilizer

[0047] The test site is in Pingba, with a mild climate and abundant rainfall; the test soil belongs to paddy soil, infiltrated paddy soil subtype, infiltrated gray-brown tidal field soil, and gray-brown tidal sand mud field soil type (U322), and the soil layer is relatively shallow , the texture of the plow layer is sandy medium soil, and the soil fertility level is medium.

[0048] Test crops: lettuce (variety is Zhutongqing).

[0049] Experimental scheme: The experiment set up 4 treatments and 3 repetitions, arranged in random blocks. The residential area is 6.00 meters long, 3.33 meters wide, and covers an area of ​​20.0 square meters. The cultivation specification is 1.2 feet x 1.2 feet, 144 plants are planted in each plot, and 4,800 plants are planted per mu. Fertilization is done as follows:

Abstract

The invention provides a special biological organic fertilizer for iron-rich green vegetables as well as a preparation method and an application of the fertilizer. The organic fertilizer is prepared from the following components in parts by weight: 60-80 parts of edible mushroom residues, 15-35 parts of humic acid, 5-15 parts of rapeseed dregs, 5-10 parts of iron in a chelating state and ferric citrate and 0.2-2 parts of a compound microbial agent. By using edible mushroom residues, humic acid and rapeseed dregs as raw materials, adding trace element iron and taking bacillus amyloliquefaciens and trichoderma aureoviride as special effect microbial bacteria, the biological organic fertilizer provided by the invention has high fertilizer efficiency and has multiple functions of improving physical and chemical properties of soil, effectively reducing soil-borne disease, improving the crop output and nutritional quality and the like.

Description

technical field [0001] The invention relates to the field of bio-organic fertilizers, in particular to a special bio-organic fertilizer for iron-rich green vegetables, its preparation method and application. Background technique [0002] Green food refers to planting and breeding under pollution-free conditions, applying organic fertilizers, not using highly toxic and high-residue pesticides, processing and producing under standard environment, production technology, and hygienic standards, and certified by authoritative organizations and using special labels. , high-quality, nutritious food. Green food and organic food are emerging industries that have developed rapidly in my country in the past two decades. With the improvement of people's living consumption level and the enhancement of food safety awareness, green food and organic food have a huge market prospect. But now there are still some problems in the process of developing green food and organic food. First, the p...
