有孔塑料薄膜水稻育苗,是在塑料薄膜上打成无数小孔,然后进行覆盖育苗。它的主要优点是:能自动调节床温,气温降低时,孔眼结成水珠,将孔封闭,保温;气温升高时,孔眼自动散热,散湿,控制床温,缓和床内温差,有利于培育壮秧。有孔薄膜的最高床温比 Porous plastic film paddy seedlings, is labeled as numerous holes in the plastic film, and then cover nursery. Its main advantages are: can automatically adjust the bed temperature, when the temperature decreases, the eyelet formed drops of water, the hole closed, heat; temperature increases, the eye automatically cooling, wet, bed temperature control, to ease the temperature difference between the bed, there Conducive to nurturing strong seedlings. The maximum bed temperature ratio of the apertured film
