草莓不是虫子变的,是花托胀大后变成的假果。草莓植物在发育过程中,花托胀大,把子房推到外部,结果处聚合果肉质,呈球形装鲜红花托,便是平常吃的草莓。而草莓上面的黑色小点,便是由草莓植物的子房,长成的真正果实,称作小瘦果,草莓种子便在小瘦果里。
草莓喜温凉气候,草莓根系生长温度5~30℃,适温15~22℃,茎叶生长适温为20~30℃,芽在-15~-10℃发生冻害,花芽分化期温度须保持5~15℃,开花结果期4~40℃。草莓越夏时,气温高于30℃并且日照强时,需采取遮荫措施。光强时植株矮壮、果小、色深、品质好;中等光照、果大、色淡、含糖低,采收期较长;光照过弱不利草莓生长。
草莓粉丝是华北及玉溪局部地区危害草莓的重要害虫。成虫和若虫群集于叶背刺吸汁液是叶片生长受阻变黄,影响植株的正常生长发育,由于成虫和若虫还能分泌大量密露堆积于叶片和果实上,往往引起煤污病的发生,严重影响叶片的光合作用和呼吸作用,造成叶片萎蔫直至植株枯死。
【英文介绍/For English】:
Strawberries are not changed by bugs, but are fake fruit after the receptacle swells. During the development of strawberry plants, the receptacle swells and pushes the ovary to the outside, and the result is aggregated fleshy, spherical red receptacles, which are commonly eaten strawberries. The black dots on the strawberry are the real fruit grown from the ovary of the strawberry plant, called a small achene, and the strawberry seeds are in the small achene.
Strawberry likes a warm and cool climate, the root growth temperature of strawberry is 5~30℃, the optimum temperature is 15~22℃, the optimum temperature for stem and leaf growth is 20~30℃, the buds are frozen at -15~-10℃, and the temperature must be maintained during the flower bud differentiation period. 5~15℃, flowering and fruiting period 4~40℃. When strawberries are over summer, when the temperature is higher than 30 ℃ and the sunshine is strong, shading measures should be taken. When the light is strong, the plants are short and strong, the fruit is small, the color is dark, and the quality is good; the medium light, the fruit is large, the color is light, the sugar content is low, and the harvesting period is long; the light is too weak.
