The principle of temperature management is to promote small seedlings and control large seedlings. That is to say, the temperature of the greenhouse where the seedlings are relatively small should be appropriately higher, and that with the larger seedlings can appropriately reduce the greenhouse temperature. In the 3rd leaf stage, the daytime temperature is controlled at 20-28°C and the nighttime is controlled at 10-12°C. During the 4-5 leaf stage, the daytime temperature is controlled at 20-25°C and the nighttime is controlled at 6-8°C. The 6-leaf period during the daytime Control at 20 ~ 25 °C, control at about 5 °C at night. Spraying foliar fertilizer During the initial flowering period of strawberry, sprayed with a protective agent such as 0.136% erythromycin B WP and potassium dihydrogen phosphate to promote plant growth, once every 5 to 7 days. Day-to-day management removes old leaves, yellow leaves, and pests and leaves in a timely manner, maintaining 5 to 6 robust leaves per plant. Timely removal of pods that accompany the vigorous growth of strawberry plants occurs, reducing nutrient consumption. Timely sparse and thinning fruit, the first inflorescence retains 4 to 7 fruit, and the second inflorescence retains 6 to 7 fruit. Prevention of diseases Gray mold and powdery mildew are the main diseases of strawberry in protected areas. Prevention should be promptly removed dead leaves, old leaves, to create air and light transmission of environmental conditions, and in the early onset of the use of Tribeceps 50% aqueous disulfiram dispersible granules spray, or with sulphur powder, chlorothalonil smoke smoke. Bee Pollination When the strawberry blooms, the bee is pollinated, and it is generally placed in the shed 5 to 6 days before the strawberry is blooming. 15 days before the bee was sprayed, the insecticides were sprayed to prevent insects. The bees must be carried out during the flowering period and then moved in after 3 days. Emotional Behavior Intervention Device
The emotional behavior intervention device is used to intervene in emotional and behavioral disorders of various special groups .Through the frequency detection and processing of music and image signals, relevant information is provided for the rehabilitation training of emotional and behavioral disorders.

Increased Strawberry Fields After Temperature Decrease
The current temperature is gradually declining, strawberry field should strengthen management and promote plant growth.
