Embodiment Construction

[0014] A high nutrient tomato fertilizer made from the following raw materials in parts by weight (kg):

[0015] Rice straw 200, kaolin 20, urea 10, sugarcane leaf 10, shrimp shell 4, peat soil 4, brown sugar 3, ferrous sulfate 0.5, sugar residue 4, fish meal 12, polyvinyl alcohol 15, tea polyphenol 1, carbon nanotube 1. β-cyclodextrin 1.2, 28% ammonia water 800.

[0016] The preparation method of the described high-nutrient tomato fertilizer comprises the following steps:

[0017] (1) Mix and grind carbon nanotubes and β-cyclodextrin for 1 hour, then add an appropriate amount of deionized water to ultrasonically disperse the resulting material for 2 hours, centrifuge, and wash the obtained precipitate twice with deionized water. Under vacuum drying for 24 hours, grind into powder;

[0018] (2) Add 10 times the amount of deionized water to polyvinyl alcohol, stir and swell at 45°C for 3 hours, then heat to 95°C and stir until the polyvinyl alcohol is completely dissolved, an...

Abstract

The invention discloses high-nutrient tomato fertilizer. The high-nutrient tomato fertilizer is prepared from raw materials in parts by weight as follows: 200-210 parts of rice straw, 20-21 parts of kaolin, 10-11 parts of urea, 10-11 parts of sugarcane top, 4-5 parts of prawn shells, 4-5 parts of peat soil, 3-4 parts of brown sugar, 0.5-0.6 parts of ferrous sulfate, 4-5 parts of candy pomace, 12-13 parts of fish meal, 15-16 parts of polyvinyl alcohol, 1-1.1 parts of tea polyphenol, 1-1.1 parts of carbon nanotubes, 1.2-1.3 parts of beta-cyclodextrin and 800-810 parts of ammonia water with the concentration of 28%. Amino groups are introduced into biochar prepared from the rice straw and can be chelated with heavy metal, the heavy metal adsorption capacity of the fertilizer is improved, and the contamination effect of the heavy metal on soil and the environment is relieved; further, the carbon nanotubes are added to an enveloping liquid, the mechanical strength of a film can be improved, and the slow release effect of the film can be improved by means of the added tea polyphenol; besides, the fertilizer contains high nutrients and can improve the yield and quality of tomatoes.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a high-nutrient tomato fertilizer and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and the quantity of rice stalks is huge. According to the annual survey and statistics, the total amount of rice stalks is about 100 million tons, and it is increasing at a rate of 100 million tons every year. In the process of using crop rice straw, the cost of machinery and equipment required in the process of collecting, transporting and utilizing rice straw is too high, the industrial chain is short, lack of technical support and misunderstandings of people's cognition and other problems make the utilization rate of crop rice straw not high In many areas, crops and rice stalks have been discarded and burned, resulting in waste of resources and environmental pollution. Biochar is made by carbonizing biomass materials such ...
