Temperature management The growth temperature of Streptomyces is 18 ℃ ～ 26 ℃. The high temperature above 30 ℃ and the low temperature below 5 ℃ are not good for strawberry growth. To reach this ideal temperature in winter, it is necessary to put a small shed inside the greenhouse And lay a film. Strive for the temperature in the shed to reach 25 ° C to 28 ° C during the day, 5 ° C above at night, and 0 ° C above the minimum temperature. If the temperature is above 32 ℃, ventilate and cool it in time. The specific temperature can be referred to as follows: before budding, 25 ℃ ～ 30 ℃ during the day, 15 ℃ at night; during budding and flowering, 22 ℃ ～ 28 ℃ during the day, 10 ℃ at night; after flowering, 20 ℃ ～ 25 ℃ during the day, 5 at night ℃; After the result, it is 15 ℃ ～ 20 ℃ during the day and above 3 ℃ at night. Water management greenhouses have high temperatures and large amounts of soil water evaporation, so they should be irrigated in time. In the early stage, the outside air temperature is high, and the irrigation is carried out in the evening; in the later period, the outside air temperature is low, and the watering is carried out in the morning. After the watering, the room temperature is increased, and then the air volume is increased to reduce the humidity. Watering should not be done too often. About one week before flowering, watering should be stopped, and fertilization should be combined with watering about 15 days after flowering. In addition to the frequent need to scrub the greenhouse film, the light management should extend the light time as much as possible. Under the premise of not affecting the temperature, the mulch and other coverings should be removed as soon as possible. In cloudy and snowy days, some brightening measures (such as installing electric lights) should be taken in the greenhouse to supplement the light. Plant management ①Artificial pollination. The method of artificial pollination is to smear the whole flower with a writing brush dipped in anther every day from 10 am to 3 pm. It is also possible to put bees in the shed. The pollination effect of bees is better than artificial pollination. The bees should be released at the early stage of flower blooming. The suitable temperature for bee activities in the shed is 15 ° C ~ 30 ° C. ② Pick leaves to remove inferior fruits. In the growing season, it is often necessary to remove the old yellow and diseased leaves that are yellowing at the lower part, and remove the stolons at any time. Before flowering and flower bud separation, the flower buds on the higher inflorescences should be properly removed; and the diseased insects and fruits should be removed in time during the young fruit cyan period.
