Fermented fertilizer containing pyroligneous liquor, and preparation method thereof

Abstract

The invention discloses a fermented fertilizer containing pyroligneous liquor, and a preparation method thereof. The fermented fertilizer is prepared from following raw materials, by weight, 50 to 100 parts of straw biochar, 10 to 15 parts of pyroligneous liquor, 200 to 250 parts of chicken manure, 100 to 135 parts of bone meal, 50 to 80 parts of potassium sulfate, 90 to 100 parts of ammonium biphosphate, 80 to 90 parts of urea, 30 to 45 parts of unprocessed rhizoma pinelliae, 20 to 30 parts of unprocessed rhizoma arisaematis, 20 to 40 parts of black false hellebore, and 8 to 10 parts of a soil modifier. The soil modifier contains jade, and a large amount of trace elements; is beneficial for human body; is capable of absorbing and solidifying toxic heavy metal elements in soil effectively, reducing absorption of heavy metal elements absorbed by crops, and increasing yield.

Description

technical field [0001] The invention relates to a fermented fertilizer and a preparation method thereof, in particular to a fermented fertilizer containing wood vinegar and a preparation method thereof. Background technique [0002] With new breakthroughs in chemical fertilizers and pesticides, the output of agricultural and forestry crops has increased year by year accordingly. How to effectively use straw waste in agricultural production and turn waste into treasure has attracted great attention. On the basis of the good matrix adsorption, temperature increase and heat preservation of straw bio-black carbon, through direct low-temperature carbonization of straw raw materials, it completely retains the original advantages of micropores and high porosity, making it an ideal long-term biochar. Sustained release. [0003] As early as 1957, Japan used wood vinegar to prevent vegetable root rot. It contains 75% polar and 25% non-polar biomass. It has been determined that there ...

Problems solved by technology

At present, in order to prevent the loss of fertilizer and water and improve the utilization rate of fertilizers, physical methods such as coating, wrapping, and coating are generally used to achieve the purpose of prolonging fertilizer efficiency, and fertilizers produced by these methods are generally expensive and rarely have pores. And adsorption capa
