Description

Technical Field

[0001] The present invention relates to the technical field of grape planting, and in particular to a control method and device for preventing early spring frost damage to grapes. Background Art

[0002] In recent years, with the continuous improvement of grape cultivation efficiency, more and more farmers have adopted grape cultivation. Although there are many farmers cultivating grapes, due to improper cultivation methods, the grapes cannot maintain the growth temperature for a long time during the cultivation period. In particular, the long period of low temperature in winter causes the grapes to grow slowly. As a result, the grapes generally do not mature until mid-June, which does not meet the demand for early maturity. For fruit farmers in northern China, if the impact of low temperatures in early spring can be reduced during the grape cultivation process, the grapes can meet the conditions for early maturity and be put on the market earlier. Summary of the Invention

[0003] The present invention provides a control method and device for preventing grapes from freezing in early spring, solving the problem in the related art that grapes cannot mature early due to low temperatures in early spring.

[0004] The technical solution of the present invention is as follows: A method for preventing early spring frost damage to grapes, comprising the following steps:

[0005] S10. Build a greenhouse: dig a cellar and build a heat-insulating greenhouse. The cellar should be rectangular and the length of the cellar should be in the east-west direction.

[0006] S20, External insulation: The outside of the greenhouse is covered with an insulation body that can be mechanically rolled up and down;

[0007] S30, ridge opening: set up grape planting ridges on the ground in the greenhouse at intervals of 15-20cm;

[0008] S40. Build a small shed: Build a small shed along the length of the ridge. The shed includes a bamboo frame and a transparent plastic film. The bamboo frame is set on the ground in an arch shape. The transparent plastic film is covered on the bamboo frame. The edge of the shed is placed on the ground and covered with soil. The shed is in harmony with the ground to wrap around the planting ridge where the seedlings have emerged. The shed has air holes for exchanging air inside and outside and is opened regularly. The shed is ventilated every 2-4 hours, and each ventilation time is 15-25 minutes.

[0009] S50. Install equipment: Install a control device outside the greenhouse. The control device includes a heating pipeline. The portion of the heating pipeline located inside the greenhouse is arranged in a serpentine shape, and the heating pipeline passing through the small greenhouse is arranged in a straight line.

[0010] S60. Temperature distribution control: A controller, a temperature sensor and an electric fan are set in the greenhouse. The temperature sensor is electrically connected to the controller and is used to sense the temperature in the greenhouse. The controller is electrically connected to the control device and controls the flow in the heating pipeline. The electric fan is electrically connected to the controller and is used to ensure sufficient air flow in the greenhouse.

[0011] As a further technical solution, in step S20, the heat-insulating body may be selected as a quilt or a straw curtain.

[0012] As a further technical solution, in step S40, the transparent plastic film is adhered to the bamboo frame by means of double-sided tape.

[0013] As a further technical solution, in step S60, there are multiple temperature sensors that are evenly distributed in the greenhouse.

[0014] The beneficial effects of the method provided by the present invention are:

The small shed puts the grapes in each ridge in a small environment. The small shed can provide a constant temperature within a small range. This constant temperature will be higher than the temperature outside the shed due to the respiration of the plants. There are connected pores between the small sheds, so as to ensure that the grapes in the shed have the air they need to breathe.

[0017] 3. A control device is installed outside the greenhouse. The control device includes a heating pipeline. The heating pipeline passes through the greenhouse and the small shed in turn and provides heat to the greenhouse and the small shed. A controller and a temperature sensor are installed in the greenhouse to ensure that the temperature inside the greenhouse and the small shed is adjustable.

The installation of the controller and the small shed can also ensure that the grapes are in the best growth state at different growth stages, reducing the impact of pests and diseases.

[0018] 4. Electric fans are also installed in the greenhouse, and temperature sensors are set at different positions in the greenhouse. When the temperature displayed by the signal transmitted to the controller by the temperature sensor is different, the electric fan rotates slowly.
