Tomato fertilizer containing rich nucleic acid and preparation method of tomato fertilizer

Abstract

The invention discloses a tomato fertilizer containing rich nucleic acid. The tomato fertilizer is prepared from raw materials in parts by weight as follows: 200-210 parts of rice straw, 20-21 parts of kaoline, 10-11 parts of urea, 10-11 parts of furnace dust, 5-6 parts of hawthorn seeds, 7-8 parts of nucleic acid wastewater, 0.3-0.4 parts of ammonium polyphosphate, 0.1-0.2 parts of a urease inhibitor, 1-2 parts of gypsum powder, 1-2 parts of amino acid powder, 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-cyclodextrine and 800-810 parts of 28% ammonia water. Amino groups are introduced to biomass charcoal prepared from the rice straw and can be chelated with heavy metal, the heavy metal adsorption capability is improved, and the pollution influence of the heavy metal on soil and the environment is reduced. The carbon nanotubes are added to a film coating liquid, the mechanical strength of a film can be improved, and added tea polyphenol can improve the slow-release property of the film; besides, the tomato fertilizer contains rich nucleic acid, the activity of tomatoes can be enhanced, decaying of the tomatoes is delayed, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a nucleic acid-rich 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 s...

Problems solved by technology

However, at present, most of the biochar is mixed with basic fertilizers and applied to the soil, which limits the transportation, storage, and application of biochar.
