preparation Embodiment 1

[0031] 1. Split the ginkgo wood into 25cm, 2cm wide, and 0.5cm thick wood chips for sufficient carbonization.

[0032] 2. Weigh 0.5 kg of ginkgo wood chips and pack them into a retort with condenser, liquid collection and metering device and gas flow meter for carbonization. This device is prior art, so its structure will not be described in detail.

[0033] 3. Use a liquid collection and metering device to collect the liquid condensed out of the condenser pipe during the carbonization process when the temperature range is from room temperature to 500 °C.

[0034] 4. After the collected liquid was left to stand for 3 months, the upper layer of light oil was removed, filtered, and the middle layer of liquid was taken to obtain ginkgo biloba vinegar.

[0035] The above-mentioned ginkgo wood vinegar was analyzed by gas chromatography-mass spectrometry HP6890N / 5973N type.

[0036] Gas chromatography conditions: choose HP-5 elastic capillary column (30mm×0.25mm×0.25um), column tem...

preparation Embodiment 2

[0040] Except that the liquid collection temperature is controlled at 150° C. to 275° C., the others are the same as in Example 1.

[0041] Adopt the method identical with embodiment 1 to analyze the wood vinegar that embodiment 2 makes, the component analysis chromatogram of gained is shown in image 3 .

preparation Embodiment 3

[0043] Except that the liquid collection temperature is controlled at 275° C. to 400° C., the others are the same as in Example 1.

[0044] Adopt the method identical with embodiment 1 to analyze the wood vinegar that embodiment 3 makes, the component analysis chromatogram of gained is shown in Figure 4 .

Abstract

The invention provides a ginkgo pyroligneous liquor and the application thereof in promoting the seed germination of crops and the growth of seedling, and the ginkgo pyroligneous liquor is prepared according to the following steps: after ginkgo wood is split into wood chips, the charring of ginkgo wood is carried out in a retort, the gas generated in the process of charring is condensed, the liquid after condensation is collected and then is placed still for three months, after that, supernatant liquid is separated, thus obtaining the ginkgo pyroligneous liquor. Proved by experiments, the ginkgo pyroligneous liquor has great promoting function on the seed germination of crops and the growth of seedling. The method for preparing the ginkgo pyroligneous liquor of the invention is simple, the obtained product is a green product of all-natural formulation and has no residue and pollution as a natural agricultural chemical substitute. The ginkgo pyroligneous liquor and the application thereof of the invention opens up a new orientation of the processing and using ginkgo wood, prompts the cultivation mode of ginkgo wood to develop into the orientation of constructing timberland used for high density in large acreage, shortening the felling cycle, solving the fear of troubles in the rear of farmers after planting ginkgo.

Description

technical field [0001] The invention relates to a ginkgo wood vinegar and its application in promoting crop seed germination and seedling growth, and belongs to the technical field of wood vinegar application. Background technique [0002] As a by-product of wood carbonization, wood vinegar has a long history. It was mainly used as a chemical raw material for processing glacial acetic acid at the beginning. With the continuous development of science and technology, the various properties of wood vinegar are gradually recognized by people, and many application fields have been opened up, such as agriculture, animal husbandry, medicine, food processing industry, forestry and health care products. Especially in recent decades, in view of the environmental pollution caused by the extensive use of chemical fertilizers and pesticides and the residual problems of harmful substances in agricultural and animal husbandry products, in response to the needs of the production of organic ...
