Embodiment 1

[0031] Embodiment 1 Synthesis of novel nitrification inhibitor

[0032] synthetic route:

[0033]

[0034] Synthesis method: Dissolve 2 mol of acrylic acid and 1 mol of itaconic acid in 100 mL of water, heat up to 70°C, add 10 mL of 5wt% hydrogen peroxide and 20 mL of 6wt% sodium hypophosphite solution dropwise at the same time, control the dropping speed, and finish dropping within 30 minutes. In the process of adding the solution, control the difference of the reaction temperature not to be higher than 1°C. After the dropwise addition, continue to raise the reaction temperature to the reflux state. After reacting for 2 hours, cool to room temperature to obtain the acrylic acid / itaconic acid copolymer.

Embodiment 2

[0035] Example 2 Synthesis of novel nitrification inhibitors

[0036] synthetic route:

[0037]

[0038]Synthesis method: Dissolve 1mol of acrylic acid and 2mol of itaconic acid in 100mL of water, heat up to 95°C, add 10mL of 10wt% hydrogen peroxide and 20mL of 10wt% sodium hypophosphite solution dropwise at the same time, control the dropping speed, finish the dropping within 50min, drop In the process of adding the solution, control the difference of the reaction temperature to not be higher than 1°C. After the dropwise addition, continue to raise the reaction temperature to the reflux state. After reacting for 5 hours, cool to room temperature to obtain the acrylic acid / itaconic acid copolymer.

Embodiment 3

[0039] Example 3 Synthesis of novel nitrification inhibitors

[0040] synthetic route:

[0041]

[0042] Synthesis method: Dissolve 1 mol of acrylic acid and 1 mol of itaconic acid in 100 mL of water, heat up to 85°C, and simultaneously add 10 mL of 7wt% hydrogen peroxide and 20 mL of 8wt% sodium hypophosphite solution dropwise. During the process of adding the solution, control the reaction temperature difference not to be higher than 1°C. After the dropwise addition, continue to raise the reaction temperature to reflux state. After reacting for 3 hours, cool to room temperature to obtain an acrylic acid / itaconic acid copolymer.

Abstract

The invention provides a nutrient fertilizer for improving the quality of black tea. The nutrient fertilizer is prepared from the following raw materials: 0.1-0.5 part of a novel nitrification inhibitor, 55-56 parts of a nitrogen fertilizer, 16-17 parts of a phosphorus fertilizer, 21-22 parts of a potassium fertilizer, 5-6 parts of a magnesium fertilizer and 1-2 parts of an anti-caking agent. Thedetermined nitrogen form and proportion suitable for black tea quality formation are provided, the black tea yield is increased, physicochemical and sensory properties of the black tea are improved, black tea nutrient management is optimized, the black tea yield and nutrient utilization efficiency are improved, the cost is reduced, manpower is saved, and the influence caused by nutrient emission to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of tea tree planting, in particular to a nutrient fertilizer and an efficient nutrient management method for improving the quality of black tea. Background technique [0002] Nutrients are the material basis for the growth of tea trees and also the decisive factor for the formation of tea quality. In the current tea production, inappropriate nutrient ratios seriously restrict the improvement of tea quality and the ecological needs of green water and green mountains. [0003] In the current practice of tea production in my country, there are the following problems regarding nutrient formulation and nutrient management: 1) The proportion of fertilizers in my country’s tea gardens is seriously inconsistent with the growth characteristics of tea trees: 40% of tea farmers use compound fertilizers of 15:15:15 corn, rice and other grains Fertilizers for field crops (reproductive growth products) are harvested, and ...
