Technical Field
[0001] The invention relates to the technical field of fruit tree cultivation, and in particular to a cultivation method for increasing the fruit size and sugar content of blue indigo fruit by utilizing a light-transmitting film. Background Art
[0002] Blue Indigo Fruit (Lonicera caerulea L.) is a deciduous shrub of the Caprifoliaceae family and the genus Honeysuckle. Its fruit is rich in nutrients and can be eaten fresh or processed into food and used in medical care. The size and sugar content of blue Indigo Fruit are one of the important indicators for measuring fruit quality, which directly affects the nutritional value and commercial value of blue Indigo Fruit. Usually, methods such as spraying plant hormones and adding fertilizers are used to increase fruit size and sugar content, but this requires a large investment of manpower and material resources, and it is difficult to control the optimal application amount under field conditions.
[0003] Light is an important environmental factor for plant growth. Light quality affects the carboxylation efficiency of plants to a certain extent, thereby affecting the carbon metabolism of plants, such as photosynthetic fixation, carbohydrate transport, conversion and accumulation, etc., and further affecting the content of various components in plants. Light of different wavelengths has an important regulatory effect on plant morphology, growth and development, physiological metabolism, and nutritional quality. In agricultural production, artificial light sources are usually used to change the spectrum, but this consumes a lot of electricity and has low economic benefits.
[0004] Changing the light quality of the environment by setting a filter film above the fruit trees is low-cost, easy to operate, green and environmentally friendly, and has good economic benefits. There are no reports on the cultivation method of using a transparent film to increase the fruit size and sugar content of blue indigo fruit. Summary of the invention
[0005] The invention aims to provide a cultivation method for increasing the fruit size and sugar content of Lonicera caerulea by using a light-transmitting film.
[0006] The present invention is achieved through the following technical solutions:
[0007] A cultivation method for increasing the size and sugar content of blue indigo fruit by using a light-transmitting film comprises the following steps: building a trellis when the blue indigo fruit turns from green to red, covering the top of the trellis with a light-transmitting film, wherein the light-transmitting film is red and a plurality of through holes are arranged on the surface of the light-transmitting film; the light-transmitting film allows sunlight to form a single red-dominated visible light below the light-transmitting film after passing through the surface of the light-transmitting film; and the through holes allow the sunlight spectrum to be irradiated on the blue indigo fruit tree unchanged.
[0008] In the present invention, the material of the light-transmitting film is not limited, and it can be a light-transmitting film such as plastic, knitted, or organic glass. The thickness of the light-transmitting film is not limited.
[0009] Preferably, the shed is constructed by combining steel pipes and scaffolding, and the shed is 0.3m to 1.5m higher than the top of the blue indigo fruit tree, which is conducive to ventilation and the growth of the blue indigo fruit tree.
[0010] In the present invention, the construction of the scaffold is not limited to the above-mentioned forms, and any form of scaffold construction can be applied to the present invention. The height, width and length of the scaffold can be adjusted according to the actual growth conditions of the blue indigo fruit tree.
[0011] Preferably, the light-shielding rate of the light-transmitting film is 70% to 95%, which effectively increases the size and sugar content of blue indigo fruit and provides other trace light for plant growth.
[0012] Preferably, the through holes are evenly arranged on the light-transmitting film, so that the visible light and the invisible light are evenly irradiated on the blue indigo fruit tree.
[0013] Preferably, the light-transmitting film is used during the growth and development period of the blue indigo fruit, and is recovered after the fruit is picked.
[0014] Preferably, the light-transmitting film covers the top of the scaffold for 35 to 50 days, which is selected according to actual use needs.
[0015] Preferably, the periphery of the light-transmitting film is open or closed. The choice is made according to actual use needs. Generally speaking, it is easier to operate with the light-transmitting film open.
[0016] Preferably, the light-transmitting film is a red sunshade net, which is cheap and easy to obtain.
[0017] The beneficial effects of the present invention are:
[0018] 1. The present invention uses a transparent film as a shed film to effectively change the light quality irradiated on the blue indigo fruit trees. The through holes make visible blue light the main illumination spectrum while ensuring that the solar spectrum is unchanged. During the development period of blue indigo fruit, after a certain period of time of transparent film coverage, the size and sugar content of the fruit are significantly improved compared with open field cultivation and black shade net cultivation.
[0019] 2. The light-transmitting film used in the present invention saves more energy than artificial light sources and can be recycled for many years. The steps for setting the light-transmitting film are simple and low in cost, so it is convenient for large-scale plantations and has good economic benefits. DETAILED DESCRIPTION
