Problems solved by technology

[0005] The purpose of the present invention is to provide a special fertilizer for ornamental flower plants, which solves the disadvantages of soil compaction, soil fertility decline and environmental pollution that are easily caused by traditional flower special fertilizers. Trichoderma harzianum, in order to improve the level of trichoderma produced by Trichoderma citricum; the trichoderma produced is better than the current special fertilizer for microbial flower plants in terms of pleiotropy and broad spectrum

Embodiment 1

[0014] 1. Using a solid medium, inoculate Trichoderma harzianum on a test tube medium, and culture it at 28°C for 2 days. The solid medium: 2% corn flour, 0.5% glucose, 1% bean cake powder, 0.2% dipotassium hydrogen phosphate, phosphoric acid Potassium dihydrogen 0.3%, calcium carbonate 1%, pH 6.0, sterilized at 121°C for 40 minutes;

[0015] Two, inoculate the Trichoderma harzianum through step 1 in a 150-liter seed tank, cultivate at 30°C, the ventilation rate is 1:0.6, the stirring speed is 200r / min, and the cultivation time is 36~48h, and the bacterial content is obtained 2×(108~109) Trichoderma complex bacterial culture;

[0016] 3. Measure 15g of urea, 12g of ammonium dihydrogen phosphate, 12g of potassium oxide, 6g of attapulgite powder, 10g of humic acid, 1g of rare earth chelated by amino acid and the rest of Trichoderma compound bacterial culture, and mix the above substances Obtain the special fertilizer for ornamental flower plants of the present invention.

Abstract

The invention discloses a special fertilizer for ornamental flower plants, relates to a special fertilizer for flowers, and belongs to the technical field of biologic fertilizers. The fertilizer is characterized in that the fertilizer comprises 25-35wt% of Trichoderma spp., 15-20wt% of urea, 12-13wt% of ammonium biphosphate, 12-13wt% of potassium oxide, 6-13wt% of attapulgite powder, 10-15wt% of humic acid and 1-2wt% of amino acid chelated rare earth. The fertilizer has the characteristics of water retention, fertilizer retention, long fertilizing time and good ventilating performance, is benefit for the root growth and the absorption and utilization of phosphorus by plants, and can effectively prevent ammonia and potassium loss and prevent the fixation of soil plant active mineral components by phosphoric acid to make soil in a loosened ventilating state for a long time, so the growth of crops is promoted.

Description

technical field [0001] The invention relates to a special fertilizer for flowers, which belongs to the technical field of biological fertilizers, in particular to a special fertilizer for ornamental flower plants. Background technique [0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions. The production level of microbial fermentation mainly depends on the genetic characteristics and culture conditions of the strain itself; the titer in microbial fermentation is the bottleneck that determines the production cost and realizes industrial production. In the world, plant diseases generally cause serious losses to agricultural production. [0003] At present, most of the biocontrol bacteria for plant diseases are fungi and bacteria isolated from soil, rhizosphere or plant surface, but the ecological environment in which they live is affecte...
