Embodiment 1

[0019] Implementation location: Soil and Fertilizer Research Institute of Yunnan Agricultural University.

[0020] Implementation materials: cow manure, chicken manure, wood vinegar

[0021] The experiment was carried out at the Soil and Fertilizer Research Institute of Yunnan Agricultural University from May 2008 to October 2008. Selection of wood vinegar: select crude wood vinegar collected at the temperature of the exhaust outlet of the carbon-distillation equipment at a temperature of 80°C to 120°C, after standing for 3 to 6 months, add charcoal powder with a weight ratio of 1 to 5% and mix well The refined wood vinegar obtained by filtering. Dilute 80% cow manure and 20% chicken manure by weight per ton of raw material and add 1 kg of wood vinegar and water to dilute 30 times and mix evenly. The carbon-nitrogen ratio (C / N) of the mixed material is 23, and the mixed material The moisture content of the mixture is adjusted to 60%, and high-temperature composting fermentat...

Abstract

The invention provides a preparation method for pyroligneous liquor and organic fertilizer mixture soil conditioner and a conditioning method thereof, belonging to the field of organic fertilizer and farm insecticide. The method comprises the following steps of in organic fertilizer compost with 70-80 percent of cow manure, diluting 1-1.5 kg pyroligneous liquor by adding 30 times of water for five times, and adding the diluted mixture in the compost, wherein the adding time is the time when starting composting is started and when the first composting temperature is 50 DEG C and when the composting temperature is 65 DEG C in subsequent times; stopping continuously stack-turning, cooling the compost body to the atmosphere temperature, drying the compost by air and sieving the compost, obtaining the pyroligneous liquor organic fertilizer mixture soil conditioner. The conditioner can be uniformly scattered on the soil surface before plowing according to the dosage of 1000 kilograms per mou, namely 5-7.5 kilograms pyroligneous liquor per mou, according to the root depth range when the crops to be cultivated in the soil are matured, the conditioner is ploughed and mixed in the root depth range when the crops is matured in the soil surface, the crops can be cultivated. By adopting the method and the conditioner and the conditioning method provided by the invention, the composting stroke can be improved prominently, the composting quality can be improved, and the physical, chemical and biological indexes of the soil which is conditioned by the conditioner can be greatly improved.

Description

technical field [0001] The invention relates to a method for preparing a soil conditioner by mixing wood vinegar and organic fertilizer obtained in the dry distillation process of plants, in particular to a method for preparing a soil conditioner by mixing wood vinegar and high-quality organic fertilizer, in particular to wood vinegar and organic fertilizer The invention relates to a method for preparing a soil conditioner by mixing high-quality organic fertilizer mainly composed of dairy cow manure, and a method for applying the conditioner to soil, belonging to the field of agricultural organic fertilizers and pesticides. Background technique [0002] Pyroligneous acid, also known as plant acid, is a reddish-brown liquid with a smoky smell obtained after the steam gas is condensed and separated during the dry distillation of biomass. It contains more than 200 organic substances such as acids, alcohols, phenols, and ketones. It is a substance that cannot be synthesized art...
