农户育秧时,一般都用新农膜,有的甚至采用双层农膜,这是因为新农膜采光效果好,但雾滴多,滴在秧苗上会影响秧苗生长;采用无滴膜覆盖育秧,效果好,但价格昂贵。 1994年冬,我市板闸镇福缘村运河组农民陈新河,将使用一月左右的新农膜,打反覆盖在大棚上培育蔬菜,(也就是把原朝外的一面朝内,原朝内的一面朝外),发现此时的农膜不仅不产生雾滴,而且棚内的蔬菜生长旺盛。成熟期也有所提前、产量也显 When farmers grow seedlings, the new plastic sheeting is generally used, and some even double plastic sheeting is used. This is because the new plastic sheeting has good lighting effects, but the droplet is more and drops on the seedling will affect the seedling growth. Good effect, but expensive. In the winter of 1994, Chen Xinhe, a farmer from Canal Group, Fuyuan Village, Banzha Town, our city, will use the new plastic sheeting in January or so to cultivate vegetables that are repeatedly covered in greenhouses (that is, Facing inward), found that the plastic sheeting at this time not only did not produce droplets, but also shed vegetables grow vigorously. Mature has also been ahead of schedule, the output is significant
