Problems solved by technology

However, in order to achieve the goal of adjusting and controlling the temperature in winter, the winter warming greenhouse needs to continuously control the temperature through the temperature control system. The construction cost is high and the daily management work is heavy. Generally, the greenhouse film is not buckled before December every year to meet the needs of apricots Cooling capacity, each development stage (especially the flowering stage) needs to strictly control the temperature according to the requirements after the canopy film is buckled in December
In spring-warm greenhouses, it is also necessary to uncover the greenhouse film every year to meet the cooling demand of the apricots and to buckle the greenhouse film and other operational measures, but does not use insulation materials such as grass thatch or quilts, and mainly adjusts the temperature inside the greenhouse by ventilating during the day and lighting a fire at night. ; The humidity is adjusted by ventilating and spraying water during the day, and the daily management work is heavy

Embodiment 1

[0025] Such as figure 1 As shown, the greenhouse includes a greenhouse support 1, a ventilation skylight 2, a ventilation side window 3, a shed door 4, a shed film 6, an anti-bird net 7, a film roll 8, a film-pressing rope 9 and a ground bolt 10. The greenhouse support 1 consists of Galvanized pipes are welded. The upper part of the greenhouse support 1 is an arched body frame structure, and the lower part is a square frame structure. The top, end and side surfaces of the greenhouse support 1 are fixedly covered with a film 6. There is a shed door 4, a ventilation skylight 2 is provided on the top shed film 6 along the direction of the shed, ventilation side windows 3 are provided on the two side shed films 6 along the direction of the shed, and the ventilation skylight 2 and the ventilation side window 3 are fixedly installed Anti-bird net 7, ventilated skylight 2, ventilated side window 3, and shed door 4 are provided with film-pressing groove 5 around, and film-pressing gro...

Embodiment 2

[0039] In 2015, the greenhouse was used for research, and a simple control measure was taken to increase the ground temperature by covering the apricot tree with black plastic film and opening and closing the ventilation side windows during the day one month before the flowering period (February 20-March 19, 2015). Recorded February 21st, February 25th, February 26th, March 1st, March 3rd, March 4th, March 5th, March 6th, March 10th in this month The temperature inside the greenhouse and the ground temperature inside and outside the greenhouse on March 13, March 14, March 15, and March 19, the test conditions are shown in Table 3, of which February 21, February 26th, March 1st, March 3rd, March 4th, March 5th, March 6th, March 10th, March 13th, March 14th, March 15th, March The accumulated ground temperature inside and outside the greenhouse on the 19th is shown in Table 4.

Abstract

The invention discloses an apricot tree protected area cultivation greenhouse and a temperature control method thereof. The top face, end faces and side faces of a greenhouse bracket are covered withgreenhouse film, wherein the two pieces of greenhouse film on the end faces are provided with greenhouse doors respectively, the greenhouse film on the top face and the greenhouse film on the two sidefaces are provided with an aeration skylight and side ventilation windows respectively in the direction of the greenhouse, the aeration skylight and the side ventilation windows are provided with anti-bird nets, the peripheries of the aeration skylight, side ventilation windows and greenhouse doors are provided with film pressing grooves, the anti-bird nets are fixed in the film pressing grooves,the greenhouse film on the top face and side faces is provided with film pressing ropes, two ends of each film pressing rope are fixed on a foundation bolt, the foundation bolts are buried in soil tobe fixed, one end of the greenhouse is provided with 3 ventilation window film winding devices, and ventilation window greenhouse film winds around the film winding devices. The apricot tree protected area cultivation greenhouse has the advantages that through the reasonable design of the sizes of the aeration skylight and side ventilation windows, after the aeration skylight and the side ventilation windows are opened, special management is not needed, greenhouse film uncovering, greenhouse film covering and other cumbersome operation do not need to be carried out every year, and apricot fruiting can be earlier at least 7 days than field cultivation when short-term temperature control management is performed.

Description

technical field [0001] The invention belongs to the technical field of protected cultivation, and in particular relates to a protected cultivation greenhouse for apricot trees and a temperature control method thereof. Background technique [0002] In recent years, the technology of apricot tree cultivation in plastic film greenhouses in my country has developed rapidly. These apricot tree cultivation greenhouses in protected areas are usually winter-warm greenhouses, which can produce apricots more than one month earlier than field cultivation. The market price is high and the economic benefits are good. However, in order to achieve the goal of adjusting and controlling the temperature in winter, the winter warming greenhouse needs to continuously control the temperature through the temperature control system, the construction cost is high, and the daily management work is heavy. Generally, the greenhouse film is not buckled before December every year to meet the demand Cool...
