Problems solved by technology

At present, most of the pesticides and plant growth regulators are acidic substances. Due to the high pH of potassium condensed phosphate, its mixed use with growth regulators and pesticides is limited.
In the current period of rapid increase in labor costs, labor costs account for a large proportion of agricultural costs, and the use of potassium condensed phosphate alone increases the cost of use and limits its use.

Embodiment 1-12

[0021] According to the weight ratio of polycondensed phosphate potassium salt and orthophosphate potassium salt, the required amount of raw materials is calculated, the raw materials are respectively pulverized, passed through a 100-120 mesh sieve, and then the raw materials are weighed according to the weight ratio to form a composition.

[0022] In order to show the regulating effect of potassium orthophosphate on the pH value of condensed potassium phosphate salt solution, Examples 1 to 12 prepared compositions according to different proportions, and then diluted 100 times into an aqueous solution (that is, the active ingredient content of 1% w / v aqueous solution), the pH value of the aqueous solution was measured, and the results are shown in Table 1. Since the pHs of potassium pyrophosphate, potassium tripolyphosphate and potassium polyphosphate aqueous solutions are all around 10, and their physical and chemical properties are very similar, only potassium pyrophosphate i...

Embodiment 13

[0034] Put 30kg of potassium tripolyphosphate and 15kg of potassium dihydrogen phosphate into 40kg of water, fully stir and dissolve, add 10kg of polyoxyethylene sorbitan monolaurate, and then add water to 100kg to form a liquid fertilizer with an effective content of 45%. , the pH value of the aqueous solution obtained by diluting 100 times is 7.12.

[0035] The use effect detection of the embodiment of the present invention, wherein increasing the crop yield is expressed by measuring the single fruit weight, increasing the sugar content of the fruit is expressed by measuring the soluble solid content in the fruit, and promoting fruit coloring is expressed by measuring the colored area of ​​the fruit. Professionally, the sugar content is generally represented by soluble sugar, total sugar or soluble solids. Soluble sugar refers to the water-soluble monosaccharides and oligosaccharides contained in the fruit. Soluble macromolecular sugars, soluble solids refer to all soluble s...

example 5

[0043] The effect of using example 5:

[0044] Treat peaches (Micha) and pears with a fertilizer with a ratio of potassium pyrophosphate / potassium dihydrogen phosphate of 4:1. The treatment time is 40 days and 20 days before the fruit is harvested. The treatment method is to add 5% of the weight of the fertilizer to the fatty acid phosphate Dilute the fertilizer 1000 times after ester (HLB=13), spray the whole plant, treat 5 trees for each fruit tree, pick 10 fruits randomly from each tree when the fruit is ripe, measure the weight of single fruit and the content of soluble solids respectively, and use water + Phosphate fatty acid esters (HLB=13) were used as controls. The results are shown in Table 3.

Abstract

The invention relates to an agricultural composition for foliage spraying. The agricultural composition is characterized in that active ingredients contain condensed phosphate potassium and orthophosphoric acid potassium, and the pH value of a 1% water solution is between 6.0 and 9.0. The agricultural composition for foliage spraying disclosed by the invention can be produced into a solid fertilizer and a liquid fertilizer, has the effects of obviously improving the yield and quality of plants, is suitable for fruit vegetables, fruit trees and the like, and solves the problem of high pH value of a polycondensation potassium phosphate solution and the problem that the polycondensation potassium phosphate solution cannot be mixed with acidic pesticides, a plant growth regulator and fertilizer.

Description

technical field [0001] The invention relates to an agricultural composition for phosphorus and potassium compound foliar spraying. Background technique [0002] Fruit sugar content and color are important characteristics of fruit quality. Fruits with high sugar content, strong flavor, good coloring and bright color are always favored by consumers, and the price is higher. Therefore, increasing the sugar content of fruit and improving the coloring of fruit is an important technical link in fruit production. There is a high correlation between the sugar content of the fruit and the coloring of the fruit. The higher the sugar content of the fruit, the better the coloring of the fruit. At present, there are many methods to promote fruit sugar increase and coloring: improving tree light conditions, thinning flowers and fruits, bagging, picking leaves, transferring fruits, and spreading reflective molds. Most of these are some agronomic measures, which are subject to various con...
