丹东市东沟县前阳公社胜利大队连续三年进行水稻有孔薄膜育苗试验,收到了较好效果。采用有孔薄膜育苗,有利于培养壮秧。因薄膜有孔,能散发水分,床内湿度较低,减少坏种、烂秧,保苗率较高。因薄膜有孔,床内透光较好,土壤受热较多,地温比无孔的一般高1～4℃,有利根系下扎。而且,床内温度稳定,有利于秧苗生长,不易得立枯病。这种方法育出的苗根系发达,秧苗健壮,干物质较多。因薄膜有孔,基本不用揭膜放风,还能够串风,起缓冲作用,不易被风吹走,吹坏,延长使用年限。
Dandong Donggou Xiangyang Commune victory unit for three consecutive years of rice perforated film nursery trials, received good results. Using perforated film nursery, is conducive to the cultivation of strong seedlings. Because the film has holes, can distribute moisture, lower humidity in the bed, reduce bad species, rotten seedlings, seedling rate is higher. Because the film has holes, the bed is better in light transmission, the soil is heated more, and the ground temperature is 1 ~ 4 ℃ higher than that of non-hole, which is favorable for the root system. Moreover, the bed temperature is stable, is conducive to seedling growth, not easy to win the damping-off. This method nurtured seedling root system developed seedling robust, dry matter more. Because the film has holes, the basic need to uncover the film blowing, but also to the wind, a buffer effect, not easy to be blown away, blowing damage, to extend the useful life.
