Problems solved by technology

[0003] At present, there are many types of plant growth regulators in the domestic market, but most of them are chemically synthesized preparations with a single effect. Elemental supply and plant cell division stimulate or regulate growth-inhibitory functions
However, multifunctional plant regulators are a large number of compounded mixtures, such as multiple chemical fertilizers mixed with trace elements, hormones, antibiotics, etc., which have complex components, difficult quality control, and high costs.
It is the first time that young coal degradation liquid is used in crops, and there is no report

Abstract

The invention relates to a production method of low-rack coal degradation liquid. Low-rack coal used as a raw material is added with 2-10% of mixed oxidizing agent, 0.1-0.6% of negative catalyst and 0.2-0.5% of stabilizer to oxidize and degrade the low-rank coal, and the mixture is subjected to oxidation reaction, centrifugalization, filtering and vacuum rotating evaporation to obtain colourless low-rack coal degradation liquid. The colourless low-rack coal degradation liquid used as a new product has good effects in promoting growth and development of crops, increasing crop output, improving the crop quality, improving the seed germination rate, improving the plant salt resistance and the like, and is a multi-functional crop conditioner (plant conditioner); the process is simple, energy-saving and environment-friendly, and high in efficiency; one set of equipment can produce the low-rack coal degradation liquid and fulvic acid simultaneously, and the low-rack coal degradation liquid is safe and non-toxic, has strong appetency to plants, can take effect rapidly and is convenient for use.

Description

technical field [0001] The invention relates to the technical field of agricultural chemistry, in particular to a production method and application of a young coal degradation liquid. Background technique [0002] In the coal-forming process of young coal-measure plants, it is a kind of low-calorific substance in the relatively early stage, with low coalification degree and poor economic benefit, and belongs to low-quality coal. According to coal classification standards, peat and lignite are collectively referred to as young coal. Young coal also maintains certain characteristics of plants, such as lignocellulose, wax, protein, amino acids, pigments, and plant-specific chemical components. Young coal is rich in high internal moisture and humic acid active substances, which can be used as a wide range of organic resources, with huge potential value and extensive utilization value. Through oxidative degradation of young coal, macromolecular humic acids can be degraded into ...
