[0060] Preparation:

[0061] (1) Preparation of biocontrol agents:

[0062] A. Trichoderma biocontrol agent:

[0063] Get 200 grams of potatoes, 20 grams of glucose, 16 grams of agar, 1000 grams of water, prepare the test tube slant medium according to the prior art, insert the Trichoderma bacterial classification, and cultivate at a constant temperature for 7 days under 27 ℃ of conditions to obtain the Trichoderma slant seeds.

[0064] Trichoderma slant seeds were eluted with sterile water to prepare Trichoderma conidia containing 1.56×10 7 One / gram suspension, get 200 grams of potatoes, 20 grams of glucose, 1000 grams of water, prepare liquid medium by prior art; With mass ratio 5wt%, suspension is inserted in the sterilized liquid medium, at 28 DEG C , and cultivated for 4 days under the con...

Embodiment 2

[0077] The raw materials of facility vegetable planting fertilizer are: 300 kg of bio-control coated urea, 450 kg of diammonium phosphate, and 250 kg of granular potassium sulfate.

[0078] Preparation:

[0079] (1) The preparation of weathered coal and binder containing biocontrol agent is the same as in Example 1.

[0080] (2) Take 300 kg of granulated urea, preheat it to 60°C in the drum, spray the binder prepared in step (1) onto the rotating urea granules, the mass ratio of the binder to urea is 0.5wt%, and then spray a layer of weathered coal containing biocontrol agent prepared in step (1). The mass ratio of weathered coal to urea is 2.5wt%. After curing, repeat the above process once to obtain a biocontrol coating urea.

[0081] (3) According to the proportioning ratio, get 300 kilograms of bio-control coated urea prepared in step (2), 450 kilograms of diammonium phosphate, and 250 kilograms of granular potassium sulfate, and mix evenly to obtain the facility vegetab...

Embodiment 3

[0083] The raw materials of facility vegetable planting fertilizer are: 350 kg of bio-control coated urea, 500 kg of diammonium phosphate, and 150 kg of granular potassium sulfate.

[0084] Preparation:

[0085] (1) The preparation of weathered coal and binder containing biocontrol agent is the same as in Example 1, except that Trichoderma is ACCC30911, and Trichoderma solid culture contains Trichoderma conidia 8.23×10 10 pc / g; Streptomyces species adopts ACCC40018, Streptomyces solid culture contains Streptomyces conidia 2.78×10 9 pcs / g.

[0086] (2) Take 400 kg of granulated urea, preheat it to 70°C in the drum, spray the binder prepared in step (1) onto the rotating urea granules, the mass ratio of the binder to urea is 0.4wt%, and then spray a layer of weathered coal containing biocontrol agent prepared in step (1). The mass ratio of weathered coal to urea is 2.0wt%. After curing, repeat the above process twice to obtain a biocontrol coating urea.

[0087] (3) Accordin...

Abstract

The invention relates to a biological disease prevention type greenhouse vegetable planting fertilizer and a preparation method and an application thereof. The greenhouse vegetable planting fertilizer is composed of bio-control coated urea, diammonium phosphate and granular potassium sulfate, the bio-control coated urea is prepared by coating granular urea by a bio-control coating agent, the bio-control coating agent is composed of bio-control agent containing weathered coal and a binder, the bio-control agent is formed by combination of a trichoderma strain bio-control agent and a streptomycete bio-control agent with a mass ratio of 1:1, and the mass of the bio-control coating agent is 4% to 9.6% of that of the granular urea. The preparation method and the application of the greenhouse vegetable planting fertilizer are further provided. A biological disease prevention type slow release nitrogen fertilizer is formed without changing a coating technique, and nutrients are rationed according to nutrient requirement rule of the vegetable seedling stage. The greenhouse vegetable planting fertilizer has the advantages that the disease prevention function can be provided for vegetables at the planting date, the fertilizer efficiency is prolonged, and damages to a root system are prevented.

Description

technical field [0001] The invention relates to a bio-disease-prevention facility vegetable planting fertilizer and a preparation method and application thereof, belonging to the technical field of fertilizer production and application. Background technique [0002] Protected cultivation has played an important role in solving the annual supply of vegetables. By 2008, the planting area of ​​protected vegetables in my country had reached more than 3 million hectares, becoming one of the leading industries in agricultural and rural economic development. However, due to the high multi-cropping index of protected cultivation, serious cropping, and special climatic conditions in the facility, soil-borne diseases often occur, and become more serious with the increase of planting years, which greatly affects the healthy development of protected vegetables. According to the survey, under the conditions of protected cultivation in our country, the occurrence of soil-borne diseases ha...
