Problems solved by technology

According to market research, most of the current methods of supplementing trace elements are single, that is, one product can only supplement one kind of trace elements. This single method of supplementing trace elements is obviously inappropriate
However, due to differences in products supplied by different suppliers, chemical reactions may occur after mixing, changing the valence state and properties of the compound, resulting in the loss of synergistic value
[0007] However, foliar fertilizers also have fatal shortcomings. Water-based foliar fertilizers are easily washed away by rain, dew, etc., and lose their original efficacy.
If it is sprayed on a sunny day, although the foliar fertilizer can be fixed on the leaf surface, the boron molybdenum fertilizer has been denatured and turned into a large particle that cannot be absorbed.

Embodiment 1

[0034] A boron-molybdenum foliage fertilizer, the addition amount of each component of the raw materials of the foliage fertilizer is: 85 parts of nano-silica sol, 35 parts of borax, 2 parts of ammonium molybdate and 0.2 part of chitosan.

[0035] A kind of preparation of nano silicon dioxide, its concrete method step is:

[0036] (1) Adopt cation exchange resin to directly filter the silicate solution through a multi-stage resin exchange column to remove metal ions in the silicate;

[0037] (2) add sulfuric acid solution and carry out acidification, obtain the active silicic acid solution that pH value is 3;

[0038] (3) Add the sodium hydroxide solution dropwise into the active silicic acid solution at a stirring speed of 800rpm until the pH reaches 9 and stop the dropwise addition, so that the silicic acid is gradually polymerized into silica particles under alkaline conditions. As the reaction time prolongs, the particle size of silica sol increases gradually, and the rea...

Embodiment 2

[0046] A boron-molybdenum foliage fertilizer, the addition amount of each component of the raw material of the foliage fertilizer is: 107 parts of nano-silica sol, 40 parts of boric acid, 3 parts of sodium molybdate and 0.3 part of polyvinylpyrrolidone.

[0047] A kind of preparation of nano silicon dioxide, its concrete method step is:

[0048] (1) Adopt cation exchange resin to directly filter the silicate solution through a multi-stage resin exchange column to remove metal ions in the silicate;

[0049] (2) add sulfuric acid solution and carry out acidification, obtain the active silicic acid solution that pH value is 4;

[0050] (3) Add the sodium hydroxide solution dropwise into the active silicic acid solution at a stirring speed of 1200rpm until the pH reaches 9 and stop the dropwise addition, so that the silicic acid is gradually polymerized into silica particles under alkaline conditions. As the reaction time prolongs, the particle size of silica sol increases gradua...

Embodiment 3

[0057] The boron-molybdenum foliar fertilizer prepared in Example 1 is sprayed on rice, and is divided into three treatments: spraying only at the jointing stage, spraying at both the jointing stage and the heading stage, and spraying at the jointing stage and the heading stage and the filling stage are all sprayed, and then a blank control is set, and the content of the pick in the brown rice is detected after the rice is mature, and the results are as shown in Table 1. It can be seen that the boron molybdenum leaf described in the present disclosure is sprayed at the jointing stage and the heading stage of the rice. The cadmium-reducing effect of surface fertilizer is the best, and the cadmium-reducing effect of spraying only at the jointing stage of rice is the smallest.

Abstract

The invention discloses boron-molybdenum foliar fertilizer. The raw material components of the boron-molybdenum foliar fertilizer comprises nano-silica sol, boron fertilizer, molybdenum fertilizer anda stabilizer. According to the boron-molybdenum foliar fertilizer, elements of boron and molybdenum are added on the basis of the nano-silica sol, so that absorption and accumulation of heavy metal cadmium, arsenic and lead in rice is reduced after spraying of the foliar fertilizer, the yield and quality of rice and other crops are improved, and trace elements required by the crops are supplemented; and since the stabilizer is added to the foliar fertilizer, the boron-molybdenum foliar fertilizer also has a stabilizing effect.

Description

technical field [0001] The disclosure belongs to the technical field of agricultural fertilizers, and in particular relates to a boron-molybdenum foliar fertilizer and a preparation method thereof. Background technique [0002] Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts its function through the absorption of leaves. The leaves of plants have upper and lower layers of epidermis, which are composed of epidermal cells. There are cuticles and waxes on the outside of the cells on the surface. layer, which can protect the mesophyll cells under the epidermis to perform photosynthesis, respiration and other functions, and not be affected by changes in external adverse conditions. Enter the plant body through the leaves to solve the problem of plant deficiency. Trace elements have been widely used all over the world, resulting in huge economic benefits. With the development of agricultural production, especially the cont...
