Embodiment 1

[0026] Dissolve wood vinegar, (stock solution PH2~3), and 10% chitosan in a ratio of 2:0.2 in water 10 times its weight, stir and dissolve at 25°C, and then add chitosan equivalent to 0.2 times the amount of chitosan Potassium dihydrogen phosphate was dissolved, and about 10 kilograms of cold-resistant and disease-resistant plant growth regulator former solutions were prepared.

Embodiment 2

[0028] Dissolve wood vinegar, (stock solution PH2~3), and 10% chitosan in a ratio of 2:0.2 in water 15 times its weight, stir and dissolve at 45°C, and then add chitosan equivalent to 0.3 times the amount Dissolve urea and potassium dihydrogen phosphate to prepare about 10 kilograms of cold-resistant and disease-resistant plant growth regulator former solution.

Embodiment 3

[0030] The original solution of the cold-resistant and disease-resistant plant growth regulator obtained in Example 1 was diluted 500 times and used in greenhouse tomatoes.

[0031] The diluted solution was sprayed on the tomatoes in the greenhouse of Lhasa Academy of Agriculture and Animal Husbandry Sciences, the incidence of the disease was reduced during the growth process of the tomatoes, the expansion period was accelerated, the color of the tomatoes was bright, and the yield was doubled.

Abstract

The invention discloses a method for preparing a plant growth regulator capable of resisting frost and preventing disease, and relates to the technical field of the plant growth regulator. The preparing method comprises the following steps: dissolving wood vinegar and 10 percent of chitosan in water with weight 10 to 15 times of the wood vinegar and the chitosan; and then stirring and dissolving at 25 to 45 DEG C; finally, adding monopotassium phosphate with weight 0.2 to 0.3 times of the chitosan; the production process of the method is very simple and convenient, and easy for industrial production; the plant growth regulator prepared by the method has obvious effects on prompting plant growth and increasing production, and is capable of activating plant cell, improving self-defense capability, being absorbed by the plant, improving the immunity of the plant, observably enhancing the effects of frost resisting and disease preventing, and improving the production and quality of grains, fruits and vegetables, etc.

Description

Technical field: [0001] The invention relates to a preparation method of a plant growth regulator with antifreeze and disease resistance, and belongs to the technical field of plant growth regulators. Background technique: [0002] Wood vinegar, also called wood vinegar or wood acetic acid, is a by-product of the charcoal firing process. The black smoke generated during the firing process is collected and condensed to obtain the "crude liquid", which is then made into wood vinegar after standing still and distilled. The composition contains 40-60% organic components. The refined liquid can be used in agriculture as well as in household cleaning products. Its pH value, specific gravity and percentage of acetic acid content are its main evaluation indicators. For example, the crude vinegar solution is brown, with a burnt and sour taste, 80% to 90% of the ingredients are water, 3% of acetic acid, 1% of tar, and many other organic components, including 6 kinds of carboxylic ac...
