Water-soluble fertilizer capable of improving color and luster of apples and promoting coloring and application method

Abstract

The invention provides water-soluble fertilizer capable of improving the color and luster of apples and promoting coloring. The water-soluble fertilizer comprises, by mass, 100-500 parts of potassium phosphate, 100-600 parts of potassium sulfate, 1-30 parts of boron polymer, 1-5 parts of molybdate, 1-10 parts of chelated zinc, 1-10 parts of chelated calcium, 1-5 parts of chelated iron, 1-5 parts of anthocyanin, 1-10 parts of potassium alginate, 1-5 parts of chitosan oligosaccharide and 1-3 parts of silica anticaking agent. The water-soluble fertilizer can improve the activity of phenylalanine ammonia-lyase and chalcone flavanone isomerase, promote synthesis of anthocyanin and provide internal environment conditions for color changing of anthocyanin, so that the color and cluster of apples are improved, coloring is even, the color and cluster are bright, the appearance commodity of apples is improved, and then the competitiveness and influence of apples in China in the international market are improved.

Description

technical field [0001] The invention belongs to the field of functional water-soluble fertilizers, and in particular relates to a water-soluble fertilizer capable of improving apple color and promoting coloring and an application method. Background technique [0002] my country's apple cultivation area and output both rank first, but my country's apples lack competitiveness in the international market. Among them, color is one of the important limiting factors that affect the sales price and sales volume of my country's apples in the international market. Fruit coloring is not only affected by light, In addition to temperature, moisture, load, pruning, bagging and other factors, mineral nutrition is also an important factor to promote coloring. At present, many orchards use some hormones or regulators for coloring, which can easily lead to physiological dysfunction of apples. , Further leading to the reduction of commercial properties such as the color of apples. The coloring...
