Strawberry is widely planted due to short planting period, quick response, high income and strong adaptability. Strawberry is a perennial herb. 10-40 cm high, stems lower than leaves or nearly equal, dense developed yellow soft hairs. The third leaves are short in leaves, thick in texture, reverse oval or diamond, dark green in upper part, few free of hairs, pale white and green in lower part, loose and raw hairs, and dense along veins; the petiole density was developed as yellow soft hair. An inflorescence of the umbrella, a lobule with a short handle below the inflorescence; flower amphiprotic; the sepal is oval and slightly longer than the auxiliary sepal; petals are white, nearly round or oval. The fruits are large in aggregate, and the surviving sepals are upright and cling to the fruits; the thin fruit tip is oval and smooth. Flowering period is 4-5 months, and fruit period is 6-7 months. The strawberry has high nutritive value, contains various nutritive substances, and has health care effect.
In general, the root system of the strawberry grows in the surface soil, and the actual growth condition of the soil surface layer can influence the growth of the strawberry. Because the strawberry root system is shallower, the soil temperature directly affects the growth of the strawberry root system, and is suitable for the growth of the strawberry root system when the soil temperature is between 15 and 23 ℃ in general. The air temperature also affects the growth of strawberries, and generally, when the air temperature is 15-23 ℃, the survival rate of strawberry field planting is higher.
In actual production, various problems exist, such as uncomfortable environmental conditions, occurrence of diseases, weaker growth vigor of strawberry seedlings and the like, and the survival rate of strawberry field planting is influenced.
