Technical Field

The invention belongs to the field of fertilization, and particularly relates to a fertilizer for promoting root growth, and a preparation method and application thereof.

Background

Whether the root system is developed or not is very important for the growth of plants such as vegetables. Calcium acts as a linkage between phosphate and carboxyl groups of proteins in cell membranes, and plays an important role in the aspects of selective absorption of ions by plants, growth, senescence, information transmission and stress resistance. Particularly root sites that support crop growth. Calcium can promote the growth of white root, prevent root rot, and enhance the resistance to environmental stress. Calcium is easy to form insoluble calcium salt in the plant body and precipitate, and can not be transferred to other growing parts of the plant, once the calcium is deficient, tender leaves firstly show symptoms, and normal growth is influenced. Therefore, calcium fertilizer supplementation is particularly important for vegetable growth. Phosphorus is also essential for normal growth of plants in the seedling stage and plays an important role in root growth and flower bud differentiation.

The existing fertilizer breaks through the aspects of calcium content and phosphorus content, but a fertilizer capable of obviously promoting root growth is lacked, so that plants can grow better.

Disclosure of Invention

The invention provides a fertilizer for promoting root growth and a preparation method and application thereof, aiming at solving the technical problem that a fertilizer capable of obviously promoting root growth is lacked in the background technology.

The technical scheme for solving the technical problems is as follows: a preparation method of a fertilizer for promoting root growth comprises the following steps:

a. diluting mineral source humic acid with the concentration of more than or equal to 150g/L and the pH value of 3-4 by 900-1000 times with distilled water to obtain a diluent;

b. adding phosphate into the diluent in the step a according to a mass ratio of 100 (9-11), and then adding a calcium-containing compound to obtain a mixed solution, wherein the mass ratio of the phosphate to the calcium-containing compound is 10: (0.5 to 0.8);

c. 1-2 days before fertilization, adding 100 parts of the mixed solution: and (4) adding active bacteria according to the mass ratio of (4) to (6) to obtain the fertilizer for promoting root growth.

The invention has the beneficial effects that: in the application of the invention, the fertilizer prepared by the preparation method of the fertilizer for promoting the growth of the root system can effectively promote the growth of the root system. The phosphate and the calcium-containing compound ensure the content of calcium ions and phosphorus ions in the fertilizer, and the mineral source humic acid is different from biochemical humic acid, has the characteristic of high activity and can stimulate the root growth. The active bacteria are added before the fertilization, so that the activity of the active bacteria can be effectively guaranteed, and meanwhile, the growth of the root system of a plant fertilization object is greatly improved. Solves the technical problem that the prior art lacks a fertilizer which can obviously promote the growth of root systems.

On the basis of the technical scheme, the invention can be further improved as follows.

Further, in the step a, the mineral source humic acid is diluted by 1000 times by distilled water.

The beneficial effect of adopting the further scheme is that diluting the humic acid to the specified times is beneficial to the mineral source humic acid to exert greater effect.

Further, in the step b, the mass ratio of the diluent to the phosphate is 100:10, the mass ratio of the phosphate to the calcium-containing compound is 10: 0.6.

The beneficial effect of adopting the further scheme is that the specified proportion can better provide calcium ions and phosphorus ions.

Further, in step c, 1 day before fertilization, active bacteria are added to the mixed solution in a mass ratio of 100: 5.

The beneficial effect of adopting the further scheme is that the effect of the active bacteria is better exerted.

Further, the calcium-containing compound is calcium aspartate.

The beneficial effect of adopting the further scheme is that calcium aspartate can effectively provide calcium ions, phosphate is not easy to precipitate, and organic nutrition is provided. Is beneficial to the growth of the plant root system.

Further, the solid phosphate is solid ammonium polyphosphate.

The further scheme has the beneficial effect that the solid ammonium polyphosphate has a relatively common ammonium polyphosphatePhosphates such as monoammonium phosphate and diammonium phosphate, which are easily changed into PO₄ ^3-And reacts with other nutrient ions to form phosphorus precipitates, thus losing effectiveness. The solid ammonium polyphosphate can provide a large amount of phosphorus ions and is not easy to generate phosphorus precipitates.

Further, the active bacteria are bacillus laterosporus.

The beneficial effect of adopting the further scheme is that the bacillus laterosporus is produced by Ulva sylvestris biology Limited.

The invention also provides a fertilizer for promoting root growth, which is prepared by the preparation method of the fertilizer for promoting root growth and is prepared from mineral source humic acid, calcium-containing compounds, phosphate and active bacteria.

The invention has the beneficial effect of greatly improving the growth of the root system of the plant fertilization object. Solves the technical problem that the prior art lacks a fertilizer which can obviously promote the growth of root systems.

The invention also provides application of the fertilizer for promoting root growth in the field of vegetables, and the fertilizer is applied to tomatoes.

The fertilizer for promoting the growth of the root system has the beneficial effect that the fertilizer can play a quite obvious role in promoting the growth of the root system in the process of fertilizing tomatoes.
