草莓按常规露地栽培产量较低,上市较迟,供应期短,效益不高。温室栽培虽可早熟高产,但建造温室成本太高,许多农户负担不起,实践证明,采用黑膜覆盖加小棚栽培,能很好地克服上述存在的诸多问题。近几年来,笔者和当地不少农户以及农场采用此法栽培草莓,效果颇理想。采果期可从当年12月开始至次年6月,比露地栽培提前上市4个多月、延后近1个月,经济效益极高。亩产一般1500公斤左右,高的达2000公斤以上,比露地栽培增产1.5～2倍,亩产值超万元。具体做法如下:
Strawberry yield by conventional open field cultivation is low, the market is late, the supply period is short, the benefit is not high. Although greenhouse cultivation can be early maturing and high yield, but the cost of building a greenhouse is too high, many farmers can not afford it. Practice has proved that the use of black film covered with shed cultivation can well overcome many of the problems mentioned above. In recent years, the author and many local farmers and farms using this method of cultivation of strawberries, the effect is quite satisfactory. Mining fruit period from the beginning of December that year to June the following year, than the open field cultivation listed more than 4 months in advance, delayed nearly 1 month, high economic efficiency. The average yield per mu is about 1,500 kg and the height is over 2,000 kg, which is 1.5-2 times more than the open cultivation. The output value per mu is over 10,000 yuan. Specific practices are as follows:
