The need for temperature and humidity in cherry growth
The need for temperature and humidity in cherry growth
The cherry belongs to the genus Prunus of the family Rosaceae, belonging to the same species as the Chinese cherries. Because the sweet cherry is large, colorful, delicious, nutritious, and fruity, it has a large gap in the Chinese market and the benefits are much higher. Chinese cherry. As a result, the planting surface of sweet cherries has been widely increased. In order to improve the yield and quality of sweet cherries during the cultivation of sweet cherries, the use of small automatic weather stations at different times is particularly important for the measurement and control of temperature and humidity in the environment. The requirements for temperature and humidity in the period are also different.
Germination to flowering, the ground temperature requirements l4 ~ 15 °C. Covering the film in the shed can allow the ground temperature to reach 14°C 10 days in advance. The temperature is 6 to 7°C at night and l8 to 20°C during the day. The relative humidity of the air in the shed is maintained at about 80%. Air humidity is low, germination and flowering are irregular, and it is also susceptible to high temperature hazards. During this period, water can be added to the tree body to increase the humidity. In the control of temperature and humidity, the field microclimate automatic observer can be used to operate. The temperature at night in flowering period is 5-7°C, and 20～22°C in daytime is appropriate. Too high or too low are not conducive to pollination and fertilization. This period should strictly avoid temperatures below -2°C and high temperatures above 25°C. During this period, the relative air humidity is 50% to 60%, too large or too small is not conducive to pollination and fertilization. Xiehua period temperature during the day 20 ~ 22 °C, 7 ~ 8 °C at night. During fruit enlargement, the daytime temperature is 22-25°C and nighttime is 10-12°C, which is beneficial to the expansion of young fruit and can be matured earlier. The fruit ripening and coloring period, the daytime temperature does not exceed 25 °C, nighttime 12 ~ 15 °C, maintains the temperature difference between day and night about 10 °C. Strictly control the daylight temperature, not more than 30 °C, and 50% relative humidity is appropriate, otherwise the fruit coloring is bad, and affect flower bud differentiation.
From the above we can see that in the specific practice, we should control the appropriate temperature and humidity according to the different growth periods. The hand-held weather station is a professional instrument used to determine the climate in the field, and it can measure the temperature, humidity, illuminance, Rainfall, carbon dioxide, and many other environmental parameters.
