Embodiment 1

[0021] This embodiment provides a biological preparation, the biological preparation includes poplar wood vinegar stock solution or a wood vinegar liquid obtained by diluting the poplar wood vinegar stock solution. It can be used to regulate the growth and development of rapeseed and improve stress resistance.

[0022] The method of poplar wood vinegar stock solution comprises: crushing poplar wood and wood chips, drying, extruding, and then putting the extruded raw material rods into a retort, at a temperature of 380-420° C. and under the condition of air isolation. Dry distillation pyrolysis produces biomass charcoal and biomass gas (or flue gas). After the biomass gas is cooled, dust removed, decoked, filtered and deacidified by the purification device, clean and high-quality gas is produced. The biomass gas cooling process What is separated from the wine is a mixture of wood vinegar and wood tar. After the mixture was left to stand for 3 months, it was allowed to settle i...

Embodiment 2

[0024] Test material: The test variety is Brassica napus variety Huayouza No. 9 (this variety passed the approval of the National Crop New Variety Approval Committee of the People's Republic of China in 2004, and is a rapeseed variety publicly promoted nationwide). In the field disease test, the rapeseed was treated with the wood vinegar prepared in Example 1 at the flowering stage of the rapeseed. (the stock solution of poplar wood vinegar was diluted to 300-500 times with water), and the control (CK) was treated with water. Storage method of treatment agent: store in refrigerator at 4°C.

[0025] Experimental environment 1: Potted plant experiments were carried out in the potted field of Huazhong Agricultural University in Wuhan City, Hubei Province. The length × width × height of the plastic box for planting is 71 cm × 45 cm × 17 cm, respectively. Yellow-brown loam is used, the mass ratio of soil to sand is 1:1, and the weight of each pot of soil is 55kg. Apply 55g of co...

Embodiment 3

[0033] Experimental environment 2: Potted plant experiment, the variety Huayouza No. 9 was selected, and it was carried out in the potted field and indoor incubator of Huazhong Agricultural University in Wuhan City, Hubei Province. In the pot test, the wood vinegar solution prepared in Example 1 was sprayed at the rapeseed three-leaf stage and eight-leaf stage respectively, and sprayed continuously for 3 days, once a day. The diameter and height of the plastic box for planting are 8cm and 14cm respectively. Yellow-brown loam is used, the mass ratio of soil to sand is 1:1, and the weight of each pot of soil is 0.9kg. Apply 0.9g compound fertilizer (N15-P15-K15) per pot, sow in potting field on March 28, 2018, settle seedlings one week after emergence, and transfer to incubator when growing to three-leaf stage (April 17), The normal temperature setting temperature is 25 / 20°C day and night, the low temperature setting temperature is 15 / 10°C day and night, the light is 20000Lx, a...

Abstract

The invention discloses a method for regulating and controlling growth and development of oilseed rape and improving resistance by utilizing poplar pyroligneous liquor. The pyroligneous liquor is obtained in the process of preparing poplar into biomass charcoal. Poplar is prepared into the biomass charcoal under an anaerobic condition at the temperature of 380-420 DEG C, and biomass flue gas generated in the process of preparing poplar into charcoal is condensed by a specific purification device to obtain liquid; and the liquid is cooled and stands for 3 months to be precipitated and divided into three layers, light oil in the upper layer and tar in the lower layer are carefully separated to obtain pyroligneous liquor in the middle layer. The pyroligneous liquor is diluted to a certain concentration and then sprayed onto leaf surfaces of plants under proper environmental conditions in different growth periods of oilseed rape. The growth and development of oilseed rape can be remarkablypromoted, the yield of oilseed rape can be increased, and the pyroligneous liquor has the effects of improving stress resistance and disease and pest resistance.

Description

technical field [0001] The invention relates to the technical field of applying a plant growth regulating treatment agent during the growth period of rapeseed, in particular to a method for regulating the growth and development of rapeseed and improving resistance (stress resistance and disease resistance) by using poplar tree vinegar. Background technique [0002] The excessive application of agricultural pesticides and fertilizers in my country has brought serious soil pollution and soil fertility decline. At the same time, the incineration of forestry and agricultural waste (wood, sawdust, straw, fruit shells, etc.) has also brought ecological environmental pollution. The energy conversion technology that uses waste biomass to make biochar can efficiently use biomass energy to produce various clean fuels and replace fuels such as coal, oil and natural gas, thereby reducing the dependence on fossil energy and reducing the impact of energy consumption on the environment. Po...
