Embodiment 1

[0023] On a hillside with a small slope, a group of two red bayberry trees is set up as a group of colored light-transmitting film sheds, such as figure 1 As shown, the color light-transmitting film shed is built with steel pipes and scaffolding. The shed is 6m high, 7-8m wide, and 11m long. The top of the scaffold is bow-shaped, covered with 5 colors of color light-transmitting film (chemical fiber material, purchased commercially, thickness is about 0.08mm) in red, blue, yellow, green, and white, and surrounded by white insect-proof nets. The color light-transmitting film and the white insect-proof net are covered at the same time when the 'Dongkui' fruit turns white. On June 15, 2018, the light intensity in the shed and the photosynthetic rate of the tree were measured during the mature stage of bayberry. And collect 50 pieces of 80d leaves from each shed and open field for the determination of leaf water content and macroelements. After the fruit was ripe, 500 g of frui...

Embodiment 2

[0044] Based on the experimental results of Example 1, the team of the present invention combines blue film, red film, green film and yellow film in pairs, and studies the influence of the color light-transmitting film of two color combinations on the quality of bayberry fruit, such as fruit size, acidity , sugar and nutritional elements.

Abstract

The invention belongs to the technical field of fruit tree cultivation, and particularly discloses a cultivation method for increasing contents of flavones and polyphenols in waxberry fruits by usinga colored greenhouse film. The method changes the light quality in a waxberry fruit growth and development environment by setting up a greenhouse covered with a bicolor light-transmitting film. The method mainly comprises the following steps: (1) land selection and greenhouse setting up: setting up a greenhouse frame with an arch top with two waxberry trees as one group; and (2) covering with thebicolor light-transmitting film: in a fruit whitening period, covering the top of the greenhouse frame with the bicolor light-transmitting film, wherein the bicolor light-transmitting film is formed by arranging yellow films and green films at intervals. Compared with a single colored film covering method, the method can significantly increase the contents of the flavones and the polyphenols in the waxberry fruits and increase the nutrient values of the fruits.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a cultivation method for increasing the flavonoid and polyphenol contents of bayberry fruit. Background technique [0002] As an important environmental factor, light can affect crop growth and development through three aspects: light intensity, photoperiod, and light quality. Light quality is one of the important factors affecting plant growth and development. It affects the carboxylation efficiency of plants to a certain extent, thereby affecting the carbon metabolism of plants, such as photosynthetic fixation, carbohydrate transportation, transformation and accumulation, etc., and then affects the sugar, The content of soluble solids such as acid. Different wavelengths of light have important regulatory effects on crop morphogenesis, growth and development, physiological metabolism, and nutritional quality. [0003] In agricultural production, in a...
