Embodiment 1

[0014] 1) Select 10-year-old Bingtang orange plants that have bloomed and produced fruit;

[0015] 2) 2-3 months before the rock sugar orange matures, spray the crown with water, spraying once every 10 days, and spraying 5 times in total;

[0016] 3) Spray water every time from 12:00 noon to 1:00 pm;

[0017] 4) Spray the amount of clear water until the tip of the leaf drips down.

[0018] 5) Compared with the control without water spraying, the fructose content in rock sugar orange pulp increased by 4.28%-4.54% over the same period.

Embodiment 2

[0020] 1) Select 10-year-old Bingtang orange plants that have bloomed and produced fruit;

[0021] 2) Spray the canopy with clean water 2-3 months before the rock sugar orange matures, spraying once every 10 days, and spraying 6 times in total;

[0022] 3) Spray water every time from 12:00 noon to 1:00 pm;

[0023] 4) Spray the amount of clear water until the tip of the leaf drips down.

[0024] 5) Compared with the control without water spraying, the fructose content in the rock sugar orange pulp increased by 4.79%-4.93% over the same period.

Abstract

The invention relates to a method for increasing the fructose content in pulp of citrus sinensis osbeck. The method comprises the following steps of 1) selecting 10-year-old citrus sinensis osbeck plants which blossom and bear fruits; 2) spraying crowns with clear water 2-3 months before the citrus sinensis osbeck is ripe, and then performing spraying once every 11 days, wherein spraying is performed for 5-6 times in total; 3), performing spraying with clear water every time from 12 o'clock in the noon to 1 o'clock in the afternoon; and 4), performing spraying with the clear water until waterdrops drop from leaf tips. The method can remarkably increase the fructose content in the citrus sinensis osbeck pulp, and the fructose content in the citrus sinensis osbeck pulp is correspondingly increased along with increase of the spraying frequency in the spraying range with the clear water for 5-6 times.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for increasing the fructose content in rock sugar orange pulp. Background technique [0002] Farmers who grow citrus in my country generally pick citrus fruits in advance every year, in order to obtain higher price benefits in advance. However, the citrus fruits picked in advance contain less sugar and more acid, and the taste quality is poor, so it is difficult to drink. How to increase the sugar content in citrus pulp has always been the focus of researchers and growers. Therefore, Xu Lishan et al. used hydrogen fluoride to fumigate Jinhua bergamot leaves, flowers and fruits to explore the impact on the content of organic nutrients; Feng Ji et al. used irradiation to irradiate citrus to explore the effects on the content of glucose, fructose and sucrose; Xiao Jiaxin et al. explored the changes of pulp free sugar, myo-inositol and potassium content during the...
