Embodiment 1

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

[0020] Implementation materials: cow dung, chicken dung, 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 liquid: select the crude wood vinegar liquid collected within the temperature of 80 ℃ ~ 120 ℃ at the exhaust port of carbon making and dry distillation equipment, after standing for 3 to 6 months, add charcoal powder with a weight ratio of 1 to 5% and mix well After filtering the obtained refined wood vinegar. The 80% dairy cow dung and 20% chicken dung are diluted 30 times with 1kg of wood vinegar per ton of raw materials and mixed evenly, and the carbon-nitrogen ratio (C / N) of the mixed material is 23. The moisture content of the compost is adjusted to 60%, and high-temperature composting is carried out. The composting process d...

Embodiment 2

[0024] Implementation site: Vegetable greenhouse in Longjie Village, Chenggong County, Kunming City, Soil and Fertilizer Research Institute of Yunnan Agricultural University.

[0025] Implementation Materials: Wood Vinegar Liquid Organic Fertilizer Mixture, Saline Soil

[0026] Experiment content: The application of a mixture of wood vinegar and organic fertilizer in soil conditioning. The field test was conducted in Longjie Village, Chenggong County, Yunnan Province from December 2009 to August 2010. Indoor analytical experiments were carried out in the laboratory of the Soil and Fertilizer Research Institute of Yunnan Agricultural University. The previous crop of the experimental site was Chinese cabbage, and the test crop was Chinese cabbage. The soil type for the test was paddy soil-plastic mud field, the texture was clay loam, and the soil conductivity (EC value) was 2.68 ms.cm -1 , the soil salt content is 4g.kg -1 , mainly grow vegetable crops. The experimental desig...

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 preparation method of mixing wood vinegar and organic fertilizer obtained in the process of dry distillation of plants to form a soil conditioner, in particular to a preparation method of mixing wood vinegar and high-quality organic fertilizer to form a soil conditioner, in particular to wood vinegar and high-quality organic fertilizer. The invention discloses a preparation method of a soil conditioner by mixing high-quality organic fertilizer mainly composed of cow dung, and a method of applying the conditioner to soil conditioning, belonging to the field of agricultural organic fertilizers and pesticides. Background technique [0002] Pyroligneous acid, also known as plant acid, is a smoky red-brown liquid obtained by condensation and separation of vapor gas in the dry distillation process of biomass. It contains more than 200 kinds of organic substances such as acids, alcohols, phenols, and ketones. It is a substance that...
