Problems solved by technology

[0004] The existing foliar fertilizers on the market generally have a single function, and most of them promote the growth of cotton. If you want to achieve other effects, you have to spray many other products, which invisibly greatly increases the cost of agricultural production. The manufacturer's foliar fertilizers are mixed and sprayed together, which is easy to produce chemical reactions and cause the loss of some functions. It is a cotton-specific foliar that integrates the functions of improving cotton resistance, preserving flowers and bolls, promoting early maturity, supplementing nutrients, and promoting growth. Fat is rare

Embodiment 1

[0031] The specific operation steps are as follows:

[0032] A. Preparation of trace element solution: Take 45 parts by weight of tap water and add it into the mixing tank to start stirring. Cu, 10 parts by weight of EDTA-Fe, 10 parts by weight of boric acid, and 5 parts by weight of sodium molybdate were added and stirred for 1 hour to obtain a trace element solution for later use.

[0033] B. Preparation of a large amount of element solution: 40 parts by weight of water, 20 parts by weight of mineral humic acid, 20 parts by weight of urea, and 20 parts by weight of potassium dihydrogen phosphate. Dissolve mineral humic acid first, then add urea, stir for 30 minutes, then add potassium dihydrogen phosphate, and mix well to obtain a large amount of elemental solution.

[0034] Adding mineral humic acid and urea first is beneficial to the stability of the product and is not prone to precipitation; otherwise, adding mineral humic acid, urea and potassium dihydrogen phosphate at...

[0039] The specific operation steps are as follows:

[0040] A. Preparation of trace element solution: Take 74 parts by weight of tap water and add it into the mixing tank to start stirring, the speed is controlled at 150 rpm, and slowly put in 5 parts by weight of EDTA-Zn, 5 parts by weight of EDTA-Mn, and 5 parts by weight of EDTA- Cu, 5 parts by weight of EDTA-Fe, 5 parts by weight of boric acid, and 1 part by weight of sodium molybdate were added and stirred for 1 hour to obtain a trace element solution for later use.

[0041] B. Preparation of a large amount of element solution: 70 parts by weight of water, 10 parts by weight of mineral humic acid, 10 parts by weight of urea, and 10 parts by weight of potassium dihydrogen phosphate. Dissolve the mineral humic acid first, then add urea, stir for 30 minutes, then add, and mix well to obtain a large amount of elemental liquid.

[0042] C. Preparation of functional substances: Take 80 parts by weight of water, 5 parts by wei...

Embodiment 3

[0045] The specific operation steps are as follows:

[0046] A. Preparation of trace element solution: Take 50 parts by weight of tap water and add it into the mixing tank to start stirring, the speed is controlled at 140 rpm, and slowly put in 10 parts by weight of EDTA-Zn, 8 parts by weight of EDTA-Mn, 8 parts by weight of EDTA- Cu, 8 parts by weight of EDTA-Fe, 10 parts by weight of boric acid, and 4 parts by weight of sodium molybdate were added and stirred for 1 hour to obtain a trace element solution for later use.

[0047]B. Prepare a large amount of elemental liquid: take 50 parts by weight of water, 15 parts by weight of mineral source humic acid, 15 parts by weight of urea, and 10 parts by weight of potassium dihydrogen phosphate, dissolve the mineral source humic acid first, then add urea, stir for 30 minutes, then add, mix After uniformity, a large amount of elemental liquid is obtained.

[0048] C. Preparation of functional substances: Take 70 parts by weight of ...

Abstract

The invention relates to a special foliar fertilizer for cotton, and a preparation method thereof. The special foliar fertilizer comprises the following components in parts by weight: 30-50 parts of atrace element solution, 30-40 parts of a macroelement solution and 20-40 parts of a functional substance, wherein the trace element solution is prepared from 45 to 74 parts by weight of water, 5 to 10 parts by weight of EDTA-Zn, 5 to 10 parts by weight of EDTA-Mn, 5 to 10 parts by weight of EDTA-Cu, 5 to 10 parts by weight of EDTA-Fe, 5 to 10 parts by weight of boric acid and 1 to 5 parts by weight of sodium molybdate, the macroelement solution is prepared from the following components in parts by weight: 40 to 70 parts of water, 10 to 20 parts of mineral source humic acid, 10 to 20 parts ofurea and 10 to 20 parts of potassium dihydrogen phosphate, and the functional substance comprises 60-80 parts by weight of water, 5-10 parts by weight of polyglutamic acid, 5-10 parts by weight of sodium tungstate, 5-10 parts by weight of trehalose and 5-10 parts by weight of amino-oligosaccharin. According to the special foliar fertilizer for the cotton and the preparation method of the special foliar fertilizer, the foliar fertilizer has multiple effects of improving the resistance of cotton, protecting flowers and bolls, promoting precocity, supplementing nutrient elements and the like, thecost can be reduced, and function loss caused by a chemical reaction generated during blending is prevented.

Description

technical field [0001] The invention belongs to the technical field of cotton fertilizers, and in particular relates to a special foliar fertilizer for cotton and a preparation method thereof. Background technique [0002] With the development of agriculture, the output of cotton is also increasing day by day, especially the addition of chemical fertilizers greatly affects the output of cotton. However, as these chemical fertilizers are applied to the soil over a long period of time, a series of problems have also been brought about. For example, the trace elements in the soil are fixed and depleted. At this time, no matter how much chemical fertilizers are applied, it is difficult to increase the yield. Applying trace elements through the soil has a low utilization rate and a large waste. Another example is that the organic matter in cotton fields decreases year by year with the application of chemical fertilizers, and the stress resistance of cotton decreases. In addition...
