Embodiment Construction
[0014] A kind of melon fertilizer that prevents soil caking is made from the following raw materials in parts by weight (kg):
[0015] Rice straw 200, kaolin 20, urea 10, peat soil 20, wheat bran 10, rare earth 4, carboxymethyl cellulose 1, potassium fulvic acid 0.2, polyvinyl alcohol 15, tea polyphenol 1, carbon nanotube 1, β - Cyclodextrin 1.2, 28% Ammonia 800.
[0016] The preparation method of the melon fertilizer that prevents soil caking 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, a...

The invention discloses a melon fertilizer capable of preventing soil from hardening. The melon 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, 20-22 parts of turfy soil, 10-11 parts of wheat bran, 4-5 parts of rare earth, 1-1.2 parts of carboxymethylcellulose, 0.2-0.3 parts of potassium fulvate, 15-16 parts of polyvinyl alcohol, 1-1.1 parts of tea polyphenol, 1-1.1 parts of carbon nano tubes, 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 rice straw and can be chelated with heavy metal, the heavy metal adsorption capability is improved, and the pollution influence of heavy metal on soil and the environment is reduced. The carbon nano tubes are added to a film coating liquid, the mechanical strength of a film can be improved, added tea polyphenol can improve the slow-release property of the film, and besides, the melon fertilizer can prevent soil from hardening.
Description
technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a melon fertilizer for preventing soil compaction 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...
