Functional composition as well as preparation method and application thereof

Abstract

The invention discloses a functional composition as well as a preparation method and application thereof. The composition is prepared from the flowing raw materials in parts by weight: 60-95 parts ofnutrient substances, 0.5-1.5 parts of organic substances and 0.07-0.15 part of active substances, wherein the nutrient substances are one or more selected from a nitrogen fertilizer, a phosphate fertilizer and a potash fertilizer, the organic substances are one or more selected from saccharides and/or amino acid, and the active substances are one or more selected from plant growth regulators. According to the functional composition as well as the preparation method and the application thereof, the problems that color turning of fruit is difficult, and the quality of the fruit is poor due to insufficient light, small temperature difference between day and night, improper cultivation and management and the like in the turning period of grapes can be solved; the nutrient substances, the organic substances and the active substances with a specific proportion are combined, the synergistic effect among all the components is fully utilized, so that a finally prepared product can provide nutrients required by growth of crops so as to promote the growth of crops, particularly, the content of anthocyanin in the grapes can be effectively increased, so that the color index of the grapes can beincreased, color conversion of the grapes can be promoted, and the quality of the grapes can be improved.

Description

technical field [0001] The invention relates to a functional composition, its preparation method and application, and also relates to a liquid fertilizer prepared from the composition. The invention belongs to the field of agricultural technology. Background technique [0002] Skin color is an important economic trait of grapes and one of the important factors to measure fruit price and market competitiveness. [0003] The color of the grape skin is caused by the accumulation of anthocyanins in the skin. The difference in the amount and type of anthocyanins makes the grapes have different colors. The anthocyanin synthesis pathway mainly includes the phenylpropanoid metabolic pathway and the flavonoid pathway. After a series of metabolisms, anthocyanins are first synthesized, and anthocyanins are combined with glucose or other sugars in cells to form anthocyanins. [0004] Among the three stages of grape fruit growth and development (including the first stage, which is the ...

Problems solved by technology

However, due to the large area of ​​grape planting in the country and the wide area of ​​planting, it is difficult to carry out fine water and fertilizer management, and some varieties such as Xiahei and Kyoho often encounter cloudy and rainy days during the color change period, with insufficient sunlight and small temperature difference between day and night. Improper cultivation and management measures used in pursuit of high yield will also affect the absorption of light by grapes, resulting in difficult coloring of grapes and poor fruit quality

The method that generally adopts at present to solve this problem, one is to use potassium-containing fertilizers to supplement nutrition, and the other is to spray growth regulators to promote color change. The first method has the problems of slow effect and poor efficiency, and the second method is only The use of growth regulators, the dosage of regulators has a narrow safety range, and the safe concentration is not easy to control. Improper use of the concentration may easily cause soft grains and threshing of the grapes in the later stage, which will affect the quality of the fruit.
