Embodiment 1

[0033] Embodiment 1 drops apply bioactivator

[0034] The biological activator of the present embodiment comprises raw material:

[0035] Glucose 0.8kg, citric acid 0.4kg, fructose 0.04kg, fucose 0.04kg, quercetin 1.6g.

[0036] Based on the total mass of the above-mentioned raw materials, apply 1.28kg per mu.

[0037] The method of preparation and application is:

[0038] Using drip application, when dripping water each time, first dissolve glucose, citric acid, fructose and fucose in water (according to biological activator: water = 5g: 100ml) to obtain a mixed aqueous solution, and use 70 ℃ of anhydrous quercetin Dissolve in ethanol (quercetin: ethanol = 1.5mg: 100ml) to obtain an alcohol solution of quercetin, and then add the alcohol solution to the above aqueous solution to prepare a bioactivator solution. Add the bioactivator solution with the fertilizer into the fertilization tank, stir and mix well, and apply it with water drops.

Embodiment 2

[0043] Embodiment 2 applies bioactivator

[0044] The biological activator of the present embodiment comprises raw material:

[0045] The biological activators are 0.9kg of glucose, 0.54kg of citric acid, 0.052kg of fructose, 0.05kg of fucose, and 2g of quercetin.

[0046] Based on the total mass of the above-mentioned raw materials, that is, 1.6kg is applied per mu of land.

[0047] Preparation and application method: At the seedling stage of the crops, use a ditch opener to open a 10cm deep ditch near the root system, mix glucose, citric acid, fructose and fucose evenly, and then spread them in the ditch, and apply quercetin at 75°C Prepare alcohol solution (quercetin: ethanol = 2mg: 100 ml) by dissolving it in absolute ethanol, add water to dilute it 40 times, and then evenly spray it into the soil (the ditch opened by fertilization). Then cover the soil and irrigate in time to promote the dissolution of the bioactivator.

Embodiment 3

[0052] Embodiment 3 drops apply bioactivator

[0053] The biological activator of the present embodiment comprises raw material:

[0054] Glucose 1.2kg, citric acid 0.4kg, fructose 0.04kg, fucose 0.06kg, quercetin 1g.

[0055] Based on the total mass of the above-mentioned raw materials, apply 3kg per mu.

[0056] The method of preparation and application is:

[0057] Using drip application, glucose, citric acid, fructose and fucose are dissolved in water (according to biological activator: water = 2.5g: 100ml) to obtain a mixed aqueous solution when dripping water each time, and quercetin is mixed with 70 ℃ anhydrous Dissolve in ethanol (quercetin: ethanol = 1mg: 100ml) to obtain an alcohol solution of quercetin, and then add the alcohol solution to the above aqueous solution to prepare a bioactivator solution. Add the bioactivator solution with the fertilizer into the fertilization tank, stir and mix well, and apply it with water drops.

Abstract

The invention discloses a biological activating agent for improving the soil phosphorus utilization as well as a preparation method and application thereof, and belongs to the technical field of agricultural soil improvement. The biological activating agent for improving the soil phosphorus utilization is prepared from the following raw materials in parts by mass: 400 to 600 parts of glucose, 200to 300 parts of citric acid, 20 to 30 parts of fructose, 20 to 30 parts of fucose and 0.5 to 3 parts of quercitrin. The biological activating agent provided by the invention is applied into soil through drip application, furrow application or hole application; the microbial activity of the soil can be regulated and controlled; the soil accumulated state phosphorus utilization efficiency is improved. After the use of the biological activating agent provided by the invention, the soil phosphatase activity is obviously enhanced; the crop yield is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural soil improvement, and in particular relates to a biological activator for improving soil phosphorus utilization, a preparation method and application thereof. Background technique [0002] Soil microorganisms play an important role in the activation and utilization of soil accumulated phosphorus (mainly including insoluble inorganic phosphorus and organic phosphorus, etc.). They can secrete protons and organic acids to dissolve soil insoluble inorganic phosphorus or secrete phosphatase to hydrolyze soil organic phosphorus. phosphorus. Due to the limitation of carbon source, soil microbial activity is often not strong, only about 5% are in an active state. Therefore, how to improve microbial activity and enhance its efficiency in activating soil accumulated phosphorus has become a research hotspot and difficulty. [0003] Root exudates are an important carbon source for soil microorganisms, ...
