草莓是一种多年生常绿宿根浆果果树,旺果龄约2—3年。它是一种投资少、效益高,颇受消费者喜爱的时令果品。利用塑料大棚地膜栽培技术可使草莓早熟和延长供应期,在自然条件下收获两茬果。 一、品种选择 大棚栽培品种一般选择“美育13号”“新明星”两个品种。这两个品种具有生长壮旺、休眠期短,抗病力强、成熟早、果大品质好、色泽艳丽;产量高、熟后不易软化并耐贮运等优点。 二、施肥整地 使用塑料大棚栽培需覆盖地膜。盖膜后,追肥次数相应减少,因而覆盖前应注意施足底肥。施肥量为亩平均施腐熟有机肥2500kg、饼肥150kg、磷肥150kg或复合肥50kg。施肥要在整地时一次性突击施入;整地要耙细整平,平均起高15—20cm,开行宽55—60cm,挖沟宽30cm。
Strawberry is a perennial evergreen perennial berry fruit, Wang fruit age of about 2-3 years. It is a less investment, high efficiency, popular consumer favorite seasonal fruit. Use of plastic shed plastic film cultivation techniques can make the strawberry premature and extend the supply period, in the natural conditions of harvest two stubble fruit. First, the choice of varieties Greenhouse cultivars generally choose “Aesthetic Education 13” “new star” two varieties. These two varieties have strong growth, short dormancy, strong disease resistance, early maturity, fruit of good quality, bright color; high yield, not easy to soften cooked and resistant to storage and transportation advantages. Second, fertilization land preparation Plastic greenhouse cover to be covered with plastic film. Cover the film, the corresponding reduction in the number of top dressing, and therefore should pay attention to Shi Shi footing before covering. Amount of fertilizer applied to the average implementation of organic fertilizer maturity 2500kg, cake 150kg, 150kg of phosphate fertilizer or compound fertilizer 50kg. Fertilization should be a one-time raid in the preparation of soil into the land preparation; to rake fine leveling, the average high 15-20cm, opening width 55-60cm, trenching width 30cm.
