Formulation and formulating method for promoting coloring of Nanguo pear fruit

Abstract

The invention discloses a preparation that can improve fruit coloring of Nanguo pear, in particular relates to a water preparation specially used for Nanguo pear. The component and concentration of the preparation are 1g / L of sucrose, 1g / L of monopotassium phosphate, 0.1g / L of abscisic acid, 0.2g / L of threonine, 0.2g / L of serine, 0.8g / L of glutamic acid, 0.22g / L of phenylalanine, 0.1g / L of levulinate, 0.6g / L of boracic acid, 100 1ml / L of tween. The preparation method is as below: step one, adding said sucrose, monopotassium phosphate, abscisic acid, threonine, serine, glutamic acid, phenylalanine, levulinate, boracic acid, tween 100 according to proportion; step two, dissolving the medicines in water (wherein, dissolving the abscisic acid by ethanol, dissolving threonine, serine, glutamic acid and phenylalanine by 100 DEG.C distilled water, dissolving monopotassium phosphate by 50-70 DEG.C distilled water), mixing after the mixture is diluted, and adding water to obtain a required concentration, mixing evenly; thus, the preparation is obtained. The red-coloring rate of Nanguo pear can be improved by more than 13% by using the preparation. The preparation can be applied conveniently, require a shorter time. The preparation has no pesticide damage and has no side effect to human body or environment.

Description

1. Technical field [0001] The invention relates to a preparation for improving the fruit coloring of Nanguo pear and a preparation method thereof, and is specially used for promoting the fruit coloring of Nanguo pear. 2. Background technology [0002] Nanguo pear is a characteristic pear in Liaoning Province. Its fruit is bright in color, delicate in flesh, refreshing and juicy, with fragrant flavor and is well-known at home and abroad. Its "high-quality Nanguo pear industrialization development and Nanguo pear high-yield and efficient cultivation model" promotion project has been included in the 2004 National Spark Program. The cultivation area of ​​Nanguo pear in Liaoning Province is 800,000 mu, with an annual output of 300,000 tons, an annual output value of more than 150 million yuan, and an annual export earnings of 30 million yuan. However, there are few high-quality Nanguo pears, especially the red fruit rate. After more than 30 years of scientific research efforts,...

AI Technical Summary

Problems solved by technology

Its purpose is to solve the problem of Nanguo pear coloring at maturity, unstable coloring before harvesting, and 100% color fading of Nanguo pears caused by rain before harvesting, resulting in a sharp decline in the nutritional value and economic value of Nanguo pears. The materials used are pollution-free and do not remain In the environment, it can significantly promote the synthesis of anthocyanins, significantly increase the red fruit rate, and significantly improve the coloring effect after fading after rain in the ripening period, and its effect is more efficient and safer than the existing technology
