Problems solved by technology

The critical value of freezing damage for loquat flowering stage is -5°C, and the critical value for freezing damage for young loquat fruit is -3°C, so when the temperature is ≤ -3°C, the young loquat fruit will be frozen; When exposed to strong light for a long time, the surface temperature of the fruit can reach above 38°C, the fruit is prone to sunburn, and the head flower is easy to be frozen. It is easy to be frozen in open field cultivation or in a greenhouse without heating facilities; the young loquat fruit is the least resistant to low temperature , it is the coldest winter in all seasons of the year, and the fruit cracking rate is high in winter, which affects the quality of loquat

Embodiment 1

[0020] An intelligent greenhouse system for professional loquat planting, including a main control device 1, an electric device 2, a temperature and humidity sensor 3, a mist mist device 4 and a ground spray device 5, the main control device 1 is connected with the electric device 2, the temperature and humidity sensor 3, and the mist spray device respectively. The mist device 4 is connected with the ground spray device 5, and the electric device 2 includes an electric film roll 2-1, a sunroof opener 2-2 and an exhaust fan 2-3, and the electric film roll 2-1 is connected with a roll film rocker 2 -4, the sky film 2-5 and the skirt film 2-6 are respectively arranged on the top and side of the greenhouse, the roll film rocker 2-4 is connected with the sky film 2-5 and the skirt film 2-6, and the skylight opener 2-2 Connect the control skylight 2-7, the temperature and humidity sensor 3 is placed in the center of the shed and in the middle and upper part of the canopy, the misting...

Embodiment 2

[0027] On the basis of Example 1, according to the comparison of weather conditions

[0028] Comparing each monitoring information with its corresponding set threshold value, comparing the weather conditions, when the temperature in the rainy awning is between the set lower limit temperature and upper limit temperature threshold, control the electric film roll 2-1, pull down to close the weather Film 2-5 and skylight 2-7, roll up and open skirt film 2-6 and exhaust fan 2-3 at the same time, keep the ventilation in the shed; The film roll device opens the sky film 2-5 and the skylight 2-7, and simultaneously opens the skirt film 2-6 to keep the ventilation in the shed.

[0029] Setting of temperature threshold: flowering period and young fruit period (10-3 months): ≤3°C mist opens, ≥5°C mist stops; growth period (3-5 months) ≥15°C film opening, ≤17°C Membrane closed; fruit ripening period (5-6 months) ≥ 30 ℃ mist open, ≤ 27 ℃ mist stop.

Embodiment 3

[0031] Comparing each monitoring information with its corresponding set threshold, and comparing the seasonal conditions, when the temperature inside the shed is lower than the set lower limit temperature threshold in winter, and when the temperature outside the shed is also lower than the set lower limit temperature threshold, control control Turn off the electric film roll 2-1, turn on the fogging device 4, turn on the fan 2-3, and keep the temperature inside the shed above 0°C; the temperature inside the shed is higher than the set upper limit temperature threshold, and the temperature outside the shed is lower than the set temperature When the upper limit temperature threshold is reached, the electric film roll 2-1 is controlled to roll up and open the skirt film 2-6 and the sky film 2-5, the skylight 2-7 and the fan 2-3 are opened, the greenhouse is ventilated, the temperature and humidity are lowered, and the greenhouse is maintained. The internal temperature is below 31°...

Abstract

The invention relates to a professional loquat planting intelligent greenhouse system and a loquat planting method. The professional loquat planting intelligent greenhouse system comprises a main control device, an electric device, a temperature and humidity sensor, a mist spraying device and a ground spraying device, wherein the main control device is connected with the electric device, the temperature and humidity sensor, the mist spraying device and the ground spraying device separately; the electric device comprises an electric film rolling device, a skylight opening device and an exhaustfan, the electric film rolling device is connected with a film rolling rocker, the top and the side of the greenhouse are provided with a top film and a skirt film respectively, the film rolling rocker is connected with the top film and the skirt film, the skylight opening device is connected with a control skylight, and the temperature and humidity sensor is arranged in the center of the shed andis located at the upper middle portion of a crown. The greenhouse has the advantages of preventing low-temperature freeze injury, preventing high-temperature sunburn, preventing fruit cracking, making maturity early, increasing the high-quality fruit rate and reducing the management cost and the labor cost.

Description

technical field [0001] The invention belongs to the field of plant planting, in particular to an intelligent greenhouse for loquat planting. Background technique [0002] Planting loquats in the northern margin, freezing damage is a major bottleneck, and the second is sunburn. The critical value of freezing damage for loquat flowering stage is -5°C, and the critical value for freezing damage for young loquat fruit is -3°C, so when the temperature is ≤ -3°C, the young loquat fruit will be frozen; When exposed to strong light for a long time, the surface temperature of the fruit can reach above 38°C, the fruit is prone to sunburn, and the head flower is easy to be frozen. It is easy to be frozen in open field cultivation or in a greenhouse without heating facilities; the young loquat fruit is the least resistant to low temperature , which coincides with the coldest winter in all seasons of the year, and the fruit cracking rate in winter is high, which affects the quality of l...
