Watermelon fertilizer for promoting growth and preparation method of watermelon fertilizer

Abstract

The invention discloses a watermelon fertilizer for promoting growth. The watermelon fertilizer is prepared from the following raw materials in parts by weight: 200-210 parts of rice straw, 20-21 parts of kaolin, 10-11 parts of urea, 10-11 parts of peat, 7-8 parts of wheat middling, 4-5 parts of melon seed shells, 0.2-0.3 part of compound sodium nitrophenolate, 0.5-0.6 part of potassium sulphate, 15-16 parts of polyving alcohol, 1-1.1 parts of tea polyphenol, 1-1.1 parts of carnon nanotubes, 1.2-1.3 parts of beta-cyclodextrine and 800-810 parts of 28% ammonia water. As biomass charcoal made of the rice straw is introduced into amino, and the amino can be chelated with heavy metals, the heavy metal adsorption property of the watermelon fertilizer is improved, and the pollution of the heavy metals to the soil and the environment is retarded; moreover, as the carbon nanotubes are added into a coating liquid of the watermelon fertilizer, the mechanical strength of a film can be increased; due to addition of the tea polyphenol, the slow-release property of the film can be improved, and in addition, the watermelon fertilizer can promote growth and development.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a growth-promoting watermelon 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 material...

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.
