1、利用农膜的颜色达到增产红色农膜可以使作物叶片吸收功能增强,作物生长旺盛,特别是对胡萝卜效果更佳,可使肉质根迅速膨大、提早上市;黄色农膜可以透过黄光、橙色光,用于扁豆栽培可使其荚果肥壮。用于莴苣和芹菜生产可改良株型,延迟食用期。用于黄瓜生产可大幅度提高产量,增产50%～100%;蓝色农膜用于韭菜、胡萝卜栽培可以提高品质,提前收获;银色农膜还具有调温作用,用于大棚蔬菜栽培,可以平抑棚内温度。 2、黄瓜增产15%的方法首先,在黄瓜幼苗2—4
1, the use of plastic sheeting to achieve increased production Red plastic sheeting can enhance the absorption of crop leaves, crop growth, especially better for carrots, fleshy roots can be swollen, the early market; yellow plastic film can be yellow , Orange light, for the cultivation of lentils can make its pods fat. For lettuce and celery production can be improved plant type, delayed edible period. For cucumber production can greatly improve the yield, yield 50% to 100%; blue plastic sheeting for leeks, carrot cultivation can improve quality, early harvesting; silver plastic sheeting also has the role of temperature control, for greenhouse vegetable cultivation, you can Stabilize shed temperature. 2, cucumber yield 15% method First, in cucumber seedlings 2-4
