[0002] Blueberries are rich in many important nutrients, among which anthocyanins are particularly noteworthy. These ingredients are not only good for health, but also show positive effects in many aspects, including preventing brain aging, protecting eyesight, enhancing cardiovascular health, fighting cancer, promoting vascular elasticity, and enhancing immune system function.

[0003] In blueberry cultivation, greenhouse technology is usually used. This planting method can facilitate management and reduce diseases. Through greenhouse planting technology, the growth of blueberries is better controlled.

[0004] However, due to the growing demand for blueberries, a larger-scale blueberry production and earlier and more flexible supply to the market are needed. Therefore, accelerating and promoting the early flowering and fruiting of blueberries will help to put blueberries on the market earlier, thereby better meeting the market demand for blueberry products. The light duration of blueberries will affect its flowering and fruiting cycle. Summary of the invention

[0025] See also Figures 1 to 6 The present application embodiment provides a method for constructing a greenhouse, which comprises the following steps:

[0026] S1: Build an outer shed 110, arrange multiple support members 101 at intervals along the first direction, and cover each of the support members 101 with a shed film 102 made of a flexible and light-transmitting material to form a planting space 103 for accommodating blueberry plants; in this embodiment, the outer shed 110 is built on the ground and is in the shape of a long tunnel, that is, the planting space 103 is in the shape of an arched tunnel. The first direction is the length direction of the outer shed 110, and the second direction is the width direction of the outer shed 110. The shed film 102 can be a plastic film made of plastic. The support members 101 are arranged at intervals along the first direction, and the distance between any two adjacent support members 101 ranges from 3 to 6 meters.

[0027] S2: constructing a supporting structure 400, and constructing the supporting structure 400 above the blueberry plants; the supporting structure 400 is arranged above the blueberry plants. It can be understood that the supporting structure 400 can be set in the planting space 103 or outside the planting space 103. There is no limitation here and it can be selected according to actual conditions.

[0028] S3: Arrange a shading structure 200, the shading structure 200 includes a first shading film 201 and a second shading film 202, both of which are made of flexible and light-blocking materials, and both of which can be made of shading cloth, which can be a plastic weed-proof cloth, a black cloth or other flexible film cloth that can block light from passing through. It is understandable that the first shading film 201 and / or the second shading film 202 can include multiple weed-proof cloths, and the weed-proof cloths are sequentially sewn together. The first light-shielding film 201 is arranged on the supporting structure 400, and two second light-shielding films 202 are arranged at intervals along the second direction, the upper end of any second light-shielding film 202 extends to be seamlessly connected or partially overlapped with the outer side of the first light-shielding film in the unfolded state (the side where the support member 101 is located), and the lower end of any second light-shielding film 202 abuts against the ground layer; the second light-shielding film 202 remains in the unfolded state during the light-shielding use, and can be kept in the folded state as needed during the non-light-shielding period.

[0029] See also Figures 1 to 6 , and the first light-shielding film 201 has an expanded state and a folded state. When the first light-shielding film 201 is in the expanded state, the first light-shielding film 201 is laid flat on top of the blueberry plant, and the two second light-shielding films are respectively located on both sides of the first light-shielding film, and the upper end of any second light-shielding film is butted against the side edge of the first light-shielding film. The first light-shielding film 201 and the two second light-shielding films 202 form a light-shielding space in the planting space 103 or outside the planting space 103, that is, the light-shielding space is located in the planting space 103, or the planting space 103 is located in the light-shielding space. There is no limitation here and you can choose according to actual conditions.

[0030] When the first light shielding film 201 and the two second light shielding films 202 are both in the unfolded state, a complete light shielding space can be provided to block the light from irradiating the blueberry plant; when the first light shielding film 201 is in the retracted state, the first light shielding film 201 allows the light to irradiate the blueberry plant. It can be understood that the first light shielding film 201 has a fixed end fixed to the supporting structure 400 and a movable end that reciprocates and retracts relative to the fixed end, and the fixed end and the movable end are arranged in sequence along the first direction, or the fixed end and the movable end are arranged in sequence along the second direction. By retracting the movable end toward the fixed end, the first light shielding film 201 is switched to the retracted state, so that the light can irradiate the blueberry plant. After the required irradiation time is reached, the movable end is unfolded in a direction away from the fixed end, and the first light shielding film 201 is switched to the unfolded state, thereby blocking the light from irradiating the blueberry plant. By switching the first light shielding film 201 between the unfolded state and the retracted state, the illumination time of the blueberry plant is controlled, and the flower bud differentiation of the blueberry plant can be promoted.

[0031] Shading can effectively promote the differentiation of flower buds of blueberry plants. In about 3 weeks, some flower buds will be visible to the naked eye, and in about 6 weeks, all flower buds will be visible to the naked eye.

[0032] See also Figures 2 to 4 The early-blooming greenhouse 100 constructed by the early-blooming greenhouse construction method provided in the embodiment of the present application can effectively promote the flower bud differentiation and flowering of blueberry plants, and is used for shading during the blueberry planting period: from May to October each year, wherein, opening the film: depending on the situation, at a certain time starting from 6 o'clock in the morning, the first shading film 201 is switched to a retracted state electrically or manually to allow each blueberry plant to fully receive light; closing the film: depending on the situation, at a certain time starting from 4 o'clock in the afternoon every day, after the blueberries have been cared for for a certain period of time, the first shading film 201 is switched to an expanded state electrically or manually to prevent light from irradiating the blueberry plants.

[0033] Optionally, the supporting structure 400 may be mesh-shaped and have a certain degree of elasticity, and the edges of the mesh-shaped supporting structure 400 may be fixed, for example, by setting a plurality of positioning columns on the ground, each positioning column being arranged in a ring shape around the shading space, and each positioning column being respectively connected to the edges of the supporting structure 400, thereby tensioning and positioning the supporting structure 400.
