Agricultural composition with function of sugar increase and coloring of fruit

Abstract

The invention relates to an agricultural composition with functions of sugar increase and coloring of fruit. The composition comprises choline salt, glutaric acid and / or a derivative of glutaric acid, ferrite, ascorbic acid and / or a derivative of ascorbic acid, and nicotinic acid and / or a derivative of nicotinic acid, wherein the choline salt accounts for 10-60% of the weight of the final composition; the glutaric acid and / or the derivative of the glutaric acid accounts for 5-30% of the weight of the final composition; the ferrite accounts for 10-60% of the weight of the final composition; the ascorbic acid and / or the derivative of the ascorbic acid accounts for 1-20% of the weight of the final composition; the nicotinic acid and / or the derivative of the nicotinic acid accounts for 1-20% of the weight of the final composition. By adopting the agricultural composition with the functions of the sugar increase and coloring of the fruit, not only can the soluble solid content of fruit be increased, but also anthocyanin generation is prompted, and meanwhile the functions of sugar increase and coloring are achieved, and manpower and material resources required by using a sugar increasing agent and a colorant respectively used are saved.

Description

field of invention [0001] The invention relates to an agricultural composition with the function of increasing sugar and coloring fruit. 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 ways to promote fruit sugar increase and coloring: such as improving tree light conditions, thinning flowers and fruits, bagging, picking leaves, transferring fruits, spreading reflective mould, controlling nitrogen or increasing phosphorus and potassium fertilize...

AI Technical Summary

Problems solved by technology

Ethephon has the effect of promoting fruit coloring, but it promotes fruit ripening, reduces fruit storability, and shortens shelf life

Moreover, some regulators such as abscisic acid and jasmonic acid are expensive and cannot be used in large quantities in production.

At the same time, because the fruit colorant is often applied before the fruit is harvested, it also brings problems such as pesticide residues and fruit quality and safety.
