bay window of Mandevilla on the seedbed bloom pink or red flowers ; the flowers string up down in the air are surrounded elegantly by branches and leaf … In the 30,000 - m2 Shuangfu Fusheng thinking greenhouse for high - end flowers and vegetables in Dongying City , Shandong Province , all variety of heyday are of dissimilar shapes and colored .
" This is the ' olive offset ' where the Shuangfu project settled ! " Recently , Mr. Liu Weitao , conductor of the Niuzhuang Town Agricultural Comprehensive Service Center , point to two silver-tongued pipes on both sides of the corridor , and said , " The circulating warming system is the heating pad for the growth of blossom . " To maintain the vigorous vitality of plant , solve the problem of heating in winter is the basal task . Traditional methods of burning coal , petroleum , or wrick on aura - conditioning for heat are costly and not environmentally well-disposed . How to solve the problem ?
This trouble has been clear very well in Niuzhuang Town . Niuzhuang Town is fat in geothermic resource , with a burial depth of about 2,000 meters and a temperature of about 85 ° C . It was originally mainly used for heating in the town ’s 240,000 m2 residential orbit . Now the heating tailwater has a " new destination " and has become the heating Department of Energy source for Shuangfu . " One m2 can lay aside about 50 RMB a year compared with coal burning . The first phase angle of the project with an region of 30,000 m2 can preserve 1.5 million RMB a year , which not only reduces product and operation cost but also achieves the green and environmental well-disposed goal . " Mr. Wang Lei , director of the Shuangfu Fusheng Agriculture Office , introduced .
The traditional theoretical account of water and plant food irrigation is eminent in consumption and scummy - efficiency . It assume two worker to irrigate 100 net ton of water and fertiliser in a traditional greenhouse of 5000 m2 , and the utilization charge per unit of water and plant food is only about 40 % . Now in Shuangfu Fusheng , a 5,000 - m2 intelligent heyday nursery adopts the technology of " tidal irrigation + plant food and H2O recycle " . Circulating irrigation of 100 stacks of water and fertiliser can achieve the 60 % recycling rate , and the utilization rate of water and fertilizer can be increase to 95 % . Irrigation once a mean solar day can ensure a sufficient plant food pace and ensure the healthy ontogeny of flowers .
The electronic screen above the entrance of the miniature arise greenhouse planting area displays various index number in the glasshouse as " Temperature 23 ° C , humidity 78 % , lighting 13000 Lux , C dioxide 450PPM " . " It ’s not like a coarse agrarian parkland , it ’s more like an intelligent factory . Managers can verify breathing , fertilization , watering , and other matter with a mobile earphone , " said technician Mr. Lu Jiangang .
These conveniences all benefit from the use of the greenhouse clime control system of rules . The temperature and humidity in traditional greenhouse are generally sensed by working experience , signified , or mere temperature and hygrometer which intend changes in the nursery can not be detected in time , and the spring up environment for flora can not be keep constant . The overbold greenhouse in Shuangfu is operate by the Internet of Things technology , all of which are exactly operate by computers .
walk in the Shuangfu planting greenhouse , the in high spirits - pressure sodium lamp is particularly middle - overhear . This is an intelligent artificial light system . Shuangfu installed 500 high-pitched - pressure sodium lamp in the planting area to imitate sunlight , tailor - made clean sources for crops , so that planting is no longer pendant on the weather , and it also solves the problem of deficient light in the traditional solar glasshouse in winter that affect the crops take in lights and slow growth .
In each greenhouse , a square box with detector is install , which is connected to the IoT restraint arrangement . consort to different season and different variety of plant , different environmental conditions can be set to realize the reflexive operation of the levelheaded greenhouse . “ The situated temperature in our miniature rose planting greenhouse is 20 ° C~25 ° C , and the humidity is 70%~85 % . ” Mrs. Zhang Xiaoqin , a 50 - year - previous villager in Weijia Village , is officious with a undimmed smile on her boldness .
Now , Mrs. Zhang has become an expert in flower planting . According to her , when the environment in the greenhouse fall below or exceeds this cooking stove , the cool organisation ( wet curtain fan ) or heating system ( intimate and outside thermal insulation equipment ) will mechanically operate , dehumidification system ( circulation devotee ) or humidification system ( spray humidifier ) will mechanically ferment on to regulate the temperature and humidity .
In the shipping area , the rapture vehicle filled with fragrancy boxes will be disinfected and drive out slowly . “ About 3000 bunches are shipped every twenty-four hour period . From the traditional cotton - growing field of study changed to the flower shop today , the output per hectare has doubled hundreds of time ! ” Mr. Wang Lei is full of sureness in future ontogenesis . The local government is also plan to use geothermic resources to develop cultural touristry projects and force more income . "
