The greenhouse cherry, which is the king of anti-season fruit in the northern part of the country, can compensate for the demand for high-end fruit in the market from spring to may. Cherry is nutritionally rich, tastes unique and suitable for all its young and old, and has high economic benefits for producers。
It's hard to grow cherry
The high value of cherries, the temperature of growth, the temperature control of greenhouse cherries are critical, the manual venting is time-consuming and the temperature of venting is not easily controlled, and there is an urgent need for the installation of the shed automatic。
1. Hibernation
The greenhouse cherries must be dormant for a long time, and the cumulative cherries hibernation of 800-1200 hours is more appropriate. The external temperature has been reduced to below 7. 2 degrees, and the temperature in the shed is 0-7. 2 degrees, which takes approximately 35-40 days。
In the case of cherries with insufficient cold storage, there is a combination of proofs of hibernation, which are mainly shown by the emergence of branches, the disparity in flowering between trees and the homogeneity of the same tree。
Flowers
Cherry temperature rises to 15 - 17 degrees before flowering, two days before temperature, at no less than 0 degrees at night, at 2 degrees per day, at 24 - 26 degrees after a week to 10 days, at 6° 8 degrees at night, at least below 0 degrees, and at 20 - 22 degrees two or three days before peach blooms。
3 cherry period temperature
Control at 18-20 degrees, not exceeding 20 degrees and night temperature 5-8 degrees, not exceeding 8 degrees。
Temperature during 4 cherry pollination
Control at 16-18 or 18-20 degrees, up to 20 degrees, and at night at 6-8 degrees
Five cherries for an expansion period
Temperature control at 20-22 degrees to hard nuclei and hard nuclei at 18-20 degrees
Six doubles to maturity
After the hard core period, the temperature is gradually moved to 22-24 degrees or 23-25 degrees, up to a maximum of 25 degrees, 10-12 degrees at night and 50 per cent humidity
Temperature before extraction 7
It's better to reduce temperatures to 20-22 degrees three to five days before early entry into maturity, increasing the hardness and elasticity of the fruit and facilitating storage
Farmer function
Core • strengths
Automatically calculates the appropriate time and duration of a switch vent based on the temperature range you want and detects real time adjustments to the switch running。
First, the whole machine is integrated, the speed-reducing machine and the temperature control instrument are reasonably installed in one of the boxes, the temperature control instrument is embedded in the case, it is easier to operate, and the case is completely closed to prevent rain showers and looks good。
Secondly, it is corrosive, highly compact, sealed and lubricated, and machines work without noise or noise。
Thirdly, speed-reducing machines use imported technology, high power exchanges, and have strong power。
Fourth, the temperature controller has a high accuracy and a failure rate of almost zero。
Fifth, ease of installation and short construction time。
Seventh, the temperature control box is equipped with a mechanical humidity table to facilitate detection of changes in humidity within the shed。
Eighth, cell phones can be remotely operated
Usage effects for users in south china
1. Make full use of temperature resources to improve the quality and yield of cherries, to set the optimal growth temperature range in accordance with the temperature requirements of cherries for different periods of growth, and to control the temperature differentials within ± 1°c to optimize the assimilation of temperature and nutrients。
2. Emancipation of the productive labour force and improvement of the efficiency of agricultural production, with the greenhouses of the cherry shed accounting for 60 to 70 per cent of the total labour input, the use of the greenhouses automatic ventilator will free farmers from heavy labour, and mobile phones will be able to operate remotely without the need to visit the sheds。
3. Reducing physical disease, reducing production costs, adjusting the speed of work automatically to the weather, significantly reducing the growth effects of sudden sudden sudden sudden drops or surges of high and low temperatures that exceed plant requirements, making temperature controls more precise and free from human error, thereby reducing the physical disease and reducing the cost of production through inputs of fertilizers。
