Problems solved by technology

Inadequate absorption of nutrients by crops due to the inability of applied fertilizers to be effectively absorbed by crops
[0003] In order to solve the problem of leaf yellowing, Cao Xiaoyan and others sprayed the mixed fertilizer containing ferrous sulfate, magnesium sulfate and citric acid on the crops, but the effect of improving the yellowing of crops was not obvious. The fundamental reason is that the use of fertilizers The rate is not high, resulting in insufficient nutrients absorbed by the crops, which cannot meet the growth needs of the crops

preparation example Construction

[0053] A kind of preparation method of the liquid fertilizer that improves crop yellowing described in the present invention comprises the following steps:

[0054] 1) the above weight percentage is taken by weighing acidic organic fertilizer, compound amino acid, calcium fertilizer, compound sugar alcohol, trace elements and water for subsequent use;

[0055] 2) Dissolve the acidic organic fertilizer, calcium fertilizer, and trace elements obtained by the above scale in water at 55-65°C in sequence, stir continuously during the addition process and add another ingredient after one ingredient is dissolved, that is, the trace element content is obtained. Elemental liquid fertilizer.

[0056] 3) Adding complex sugar alcohols and compound amino acids sequentially to the liquid fertilizer containing trace elements, stirring continuously during the adding process and adding another component after dissolving one component, a liquid fertilizer for improving crop yellowing is obtaine...

Embodiment 1

[0060] A liquid fertilizer for improving crop yellowing, the composition of which comprises by weight percentage:

[0061] 40% of wood vinegar, 15% of aspartic acid, 10% of calcium ammonium nitrate, 20% of sorbitol, 5% of trace elements and 10% of water; 30% of chelated zinc in trace elements, 10% of boric acid, EDTA Chelated iron 50%, ammonium molybdate 10%. Its preparation method is as follows:

[0062] 1) Weigh aspartic acid according to the ratio of wood vinegar 40%, aspartic acid 15%, calcium ammonium nitrate 10%, sorbitol 20%, trace elements 5% and water 10% in the raw material composition acid, wood vinegar, calcium ammonium nitrate, sorbitol, EDTA chelated zinc, boric acid, EDTA chelated iron, ammonium molybdate and water;

[0063] 2) The wood vinegar, calcium ammonium nitrate, EDTA chelated zinc, boric acid, EDTA chelated iron, and ammonium molybdate weighed in 1) were dissolved in water at 55-65°C in sequence, stirring continuously and One component is dissolved a...

Embodiment 2

[0067] A liquid fertilizer for improving crop yellowing, the composition of which comprises by weight percentage:

[0068] 40% aspartic acid, 15% calcium ammonium nitrate, 25% sorbitol, 5% trace elements and 15% water; 30% EDTA chelated zinc, 10% boric acid, 50% EDTA chelated iron, Ammonium molybdate 10%.

[0069] The preparation method is consistent with that described in Example 1.

[0070] According to the application method in Example 7, the liquid fertilizer for improving crop yellowing in Example 2 was applied to the grapes, and the soil was well improved, and the quality of the crops was improved at the same time. The content of chlorophyll in the leaves increased by 2%. , the grapes produced in the current season will increase by 0.5 Brix.

Abstract

The invention discloses liquid fertilizer for improving yellowing of crops. The liquid fertilizer is prepared from the following components in percentage by weight: 15 percent to 25 percent of compound sugar alcohol, 10 percent to 20 percent of compound amino acid, 35 percent to 50 percent of acidic organic fertilizer, 5 percent to 15 percent of calcium fertilizer, 5 percent to 15 percent of microelement and the balance of water. According to the liquid fertilizer disclosed by the invention, the microelement and the compound amino acid form a compound through utilizing a reasonable proportion relation of the acidic organic fertilizer, the compound amino acid, the calcium fertilizer, the compound sugar alcohol, the microelement and the water, so that the absorption capability of crops on the microelement is improved and the utilization rate of the fertilizer is improved; meanwhile, the compound sugar alcohol and mineral elements in soil form a compound so that the environment of the soil is improved and the permeability of the soil is improved, and furthermore, a root system can easily absorb nutrients from the soil; meanwhile, the compound can also enter phloem parts of the crops and the nutrients needed by the growth of the crops are met; the utilization rate of the fertilizer is improved and the yellowing of the crops is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a liquid fertilizer for improving crop yellowing. Background technique [0002] The yellowing of crop leaves generally has the following two situations: 1) Nutrient factors, physiological diseases caused by lack of certain nutrients. Due to the lack of trace elements or the calcium, nitrogen, phosphorus, and potassium elements needed for plant growth, the new leaves of the plants gradually turn yellow, and finally gradually turn yellow-white, while the old leaves remain green. 2) Environmental factors, yellowing of leaves due to harsh environmental conditions. There are several possibilities for this situation: ① Due to the accumulation of a large amount of residual fertilizer in the soil during the production period, the soil is compacted or salinized, so that the crops cannot get enough nutrients from the soil. ②Utilization rate of fertilizer. Since the applied fertilize...
