Embodiment 1

[0012] In 2016, related experiments were carried out in an orchard in Minhou County, Fujian Province. The experimental peach variety was'Okubo'. A five-year-old uniformly growing tree in the orchard was selected for spraying experiments. The fruit coloring effect was carried out by investigation and statistics. After 3 days of spraying isosorbide aqueous solution each time, 20 fruits of each tree were unpacked to observe and count the coloring conditions (count the number of fruits whose redness area reached or exceeded half), and calculate the percentage.

[0013] Control group: 10 fruit trees with bagged fruits on May 10 were sprayed with clean water every 2 weeks after bagging on the same day. After the fruits were unbagged, no pharmaceutical solution was sprayed.

[0014] Treatment group: The concentration of isosorbide was sprayed 4 times in this treatment during the production period. The concentration was calculated according to the formula F(x) = 60-10x. When the first spray...

Embodiment 2

[0019] Related experiments were conducted in an orchard in Fuzhou City, Fujian Province in 2017. The experimental peach variety was ‘Taiwan Crispy Peach’. A five-year-old uniformly growing tree in the orchard was selected. The fruit coloring effect was carried out by investigation and statistics.

[0020] Control group: 10 fruit trees with bagged fruits on April 8 were sprayed with clean water every 3 weeks after the bagging on the same day. After the fruits were unbagged, no pharmaceutical solution was sprayed.

[0021] Treatment group: The concentration of isosorbide was sprayed twice during the production period. The concentration was calculated according to the formula F(x) = 60-10x. When the first spray was x=1, the concentration of isosorbide F( x)=50mg / L; at the second spraying, x=2, and isosorbide concentration F(x)=40mg / L. The arrangements are as follows:

[0022] Treatment 1: 10 fruit trees with bagged fruits on April 8 were sprayed with isosorbide aqueous solution every 3...

Abstract

The invention provides a method for improving bagged-peach fruit coloring. After peaches are bagged, an isosorbide aqueous solution with a certain concentration is sprayed to whole trees every 2-3 weeks; after bags are unfastened, an isosorbide aqueous solution with a low concentration is sprayed to whole trees, and one time is optimal; and spraying is performed for 5 times at the most in a whole fruit growth period. The method is simple in operation, economic and effective, has no harmful substance residues, improves bagged-peach fruit coloring, and improves economic value.

Description

Technical field [0001] The invention belongs to the technical field of fruit tree production, and specifically relates to a method for improving the coloring of bagged peach fruits. Background technique [0002] Fruit coloring is an important indicator of the appearance quality of peach fruits and an important factor for consumers to measure the value of fruit products. Fruit bagging is helpful to keep the surface of mature fruits smooth, but the coloring effect is generally not as good as that of fruits grown naturally in the open air. How to effectively improve the coloring of bagged fruits has always been a common concern for fruit trees at home and abroad. [0003] Studies have shown that the effect of peach fruit coloring is related to the dynamic balance of chlorophyll, carotenoids, flavonoids and anthocyanins in the peel. Affects the balance, accelerates the degradation or accumulation of specific pigments, and can also significantly change the color of the fruit. Some me...
