塑料大棚栽培草莓,亩产可达2000公斤,最高达3000公斤,亩产值达2万余元。现将草莓高效益栽培技术介绍如下:一、选用壮苗要选用根系发达、叶柄短粗的4～5片叶,叶色浓绿的为最好。二、整地作垄整地前应亩施肥5000公斤以上, 并适当混施磷钾肥,亩用过磷酸钙100公斤,钾肥50公斤。深翻30厘米耙平,作垄,垄高15～20厘米。垄面宽40～50厘米,垄沟宽30厘米,南北走向。三、适期定植草莓的根在地温20℃上下生长最好,黑龙江省一般在8月中旬栽植,移栽时带土坨成活率高,每垄栽2行,深度以深不埋心,浅不露根为宜,每亩栽8000株左右。栽后及时浇水,连浇2～3次,之后经常保持土湿润。四、适期扣棚在土壤上冻前扣完,扣棚后及时覆盖地膜,最好用黑色地膜,有利于提高地温。11月中旬,温室外覆盖草苫,不加温,草莓即可安全越冬。
Plastic greenhouse cultivation of strawberry, per mu up to 2000 kg, up to 3000 kg, mu output value of 2 million yuan. Strawberry high efficiency cultivation techniques are introduced as follows: First, the selection of strong seedlings to choose developed root system, petiole stubby 4 to 5 leaves, dark green leaves for the best. Second, before land preparation for land consolidation, 5000 mu of fertilization should be applied per mu and phosphorus and potassium fertilizer should be properly mixed with 100 kg of superphosphate and 50 kg of potash. Deep flip 30 cm rake flat, ridge, ridge height 15 to 20 cm. Ridge width of 40 to 50 cm, 30 cm wide ditch, north-south direction. Third, the appropriate planting strawberry root temperature at 20 ℃ up and down the best growth, Heilongjiang Province generally planted in mid-August, when transplanted with Tuo Tuo survival rate of high, each ridge planted 2 lines, the depth of deep not buried, shallow shallow Lu root appropriate, planted about 8000 plants per mu. Timely watering after planting, and even poured 2 to 3 times, often after keeping the soil moist. Fourth, the appropriate deduction shed frozen in the soil before the buckle finished, after the deduction shed coverage of the film, it is best to use black plastic film, is conducive to improving the ground temperature. In mid-November, the grass covered with grass outside the greenhouse, not warm, strawberries can safely wintering.
