The cultivation mode of grapes is generally based on the cultivation of facilities. With the development in recent years, the production of facilities grapes has grown from simple to complex, from courtyards to fields, from small areas to large-scale regional development. The seedless white chicken heart grape was selected for greenhouse cultivation, and the “multi-arc dwarfing†three-dimensional cultivation technology model was adopted to begin large-scale production. The temperature and humidity monitor measures and analyzes the relevant parameters of temperature and humidity in the greenhouse, and provides scientific basis for the cultivation measures.
In the east-west direction of the greenhouse, the orientation of the greenhouse in the west is adjusted to 5-8° according to the topography. Each building is 80-100m long and spans 7-7.5m. It is a wooden brick-concrete structure with an area of ​​667m2 each. The ridge height of the greenhouse is about 2.8m, the back wall is about 2.0m high, and the front bottom corner is 1.2m high. The back wall and the gables on both sides are hollow brick walls with a thickness of 30cm. The roof is arched in a circular shape and the two greenhouses have a spacing of about 8m. For the control of the temperature, humidity, and other conditions required by the grape, it must be measured and analyzed in strict accordance with the temperature and humidity monitor.
In late October, the grapes are pruned in winter and covered with plastic film and covered with straw curtains. The grapes are in dormant period. The temperature in the greenhouse is controlled at -5° to 7°C. The grapevines in greenhouses in winter do not need to stand cold in order to ripen the greenhouses. The period is extended to avoid centralized listing and to ease the sales contradiction. Each year from the beginning of December to the beginning of February, it begins to explode. Pregerminating Note: Do not warm up too fast, during the first two weeks of warming temperature during the day at 15 ~ 20 °C, 7 ~ 15 °C at night, after the first 3 weeks to the germination temperature during the day is 20 ~ 25 °C, night 10 ~ 15 °C; Growth period: daytime 25-35°C, nighttime 10-15°C, minimum temperature not lower than 10°C; flowering period: daytime 22-26°C, nighttime 15-20°C, minimum not lower than 15°C; berry development period: daytime 25 ~ 28 °C, night 10 ~ 22 °C; coloring mature period: 28 ~ 32 °C during the day, 14 ~ 16 °C at night, the temperature difference between day and night this period is best in 10 °C.
The temperature and humidity monitor will control the humidity in the greenhouse under greenhouse cultivation conditions, increase photosynthesis and reduce disease occurrence. The germination period has a humidity of 80% to 90%, the humidity during the growth period of the shoots is 70% to 80%, the humidity during the flowering period is 50% to 60%, and the humidity during the berry development period and the coloration and maturation period is 50% to 70%. In order to control the humidity in the greenhouse, it is necessary to adopt drip irrigation under the membrane. After the water is sprayed, the ventilation openings shall be opened in time, the humid air shall be discharged outside the shed, and the ventilation openings shall be promptly closed before rain to prevent the rain from splashing.
