Embodiment 1

[0054] Prepare raw materials according to the following parts by weight: 530 parts of water, 150 parts of potassium nitrate, 50 parts of urea, 50 parts of potassium dihydrogen phosphate, 100 parts of potassium fulvic acid, 50 parts of amino acid powder, 10 parts of zinc sulfate, 10 parts of ferrous sulfate , 10 parts of boric acid, 10 parts of glucose, 10 parts of sodium alginate, 5 parts of sodium nitrophenolate, 10 parts of paclobutrazol, and 5 parts of PEG4005. According to the above-mentioned preparation method, the finished product preparation, i.e. the special root-promoting agent for tobacco, is prepared. Experimental location: Network Room, College of Resources and Environment, South China Agricultural University. The tested tobacco varieties were K326 and Xiangyan 4 (XY4). When the tobacco seedlings grew to 6 leaves and 1 heart, they were transplanted into potting soil for control and root-promoting agent treatment. Each treatment was repeated 4 times, and one tobacc...

Abstract

The invention discloses a root growth promoting agent for tobacco, its preparation and application. The root growth promoting agent comprises the following ingredients: 100-150 weight parts of potassium nitrate, 50-100 weight parts of urea, 10-50 weight parts of potassium dihydrogen phosphate, 10-50 weight parts of amino acid powder, 5-10 weight parts of zinc sulfate, 5-10 weight parts of ferrous sulphate, 5-10 weight parts of boric acid, 5-10 weight parts of sodium alginate, 5-10 weight parts of glucose, 5-10 weight parts of compound sodium nitrophenolate, and 5-10 weight parts of paclobutrazol. The root growth promoting agent disclosed herein can simultaneously provide tobacco with organic and inorganic nutrition, macro and trace nutrients, and root growth promoting factors with physiological activity, has the effect of improving tobacco rhizosphere environment, and can rapidly induce the rooting and growth of seedlings. The root growth promoting agent disclosed herein can be applied by blade spraying, hole irrigation, root irrigation and the like. Compared with the control group, the total number of roots which is subject to the application of the root growth promoting agent increases by 5.04-35.19%, the root dry weight increases by 5.69-32.47%, and the root volume increases by 7.99-36.75%. The root growth promoting agent disclosed herein can be widely applied in tobacco production.

Description

technical field [0001] The invention belongs to the technical field of plant growth regulators, in particular to a regulator for promoting the growth of tobacco roots (hereinafter referred to as: root promoting agent). Background technique [0002] The root system is the main part of the tobacco plant to absorb mineral nutrients and water. To make the tobacco plant root system have a strong absorption capacity, it is necessary to promote root system development. After the tobacco seedlings are transplanted, if the rooting rate is fast, the tobacco plants will have a strong ability to resist external stress. At the same time, the greater the depth of the tobacco root system, the stronger the ability of the tobacco plant to resist drought, and it is not easy to lodging. Because tobacco roots can synthesize hormones and alkaloids, tobacco roots are likely to be the brain or control center of tobacco plants. The biomass of tobacco roots is closely related to tobacco yield and n...
