有孔薄膜育苗从七五年开始小区试验,经过群众观察鉴定,认为效果良好。七六年又在八个生产队进行了大面积试验和示范,面积为513床。试验的结果又表明,这种育苗方法具有强大的生命力,很有前途,深受群众欢迎。但也存在一定问题,应该注意。一、有孔薄膜育苗的优点1、能防高温,缩小温差,秧苗健壮有孔薄膜育苗,因膜上有孔洞,能自动通风降温,所以在每天的高温阶段,其床
Porous film nursery from 1970 to start a district test, after mass observation and identification, that the effect is good. In 1976, a further eight large-scale trials and demonstrations took place in eight production teams with an area of 513 beds. The results of the experiment also show that this method has a strong seedling vitality, promising, well received by the public. But there are some problems, it should be noted. First, the advantages of perforated film nursery 1, to prevent high temperature, reduce the temperature difference, seedling robust perforated film nursery, due to the membrane holes, automatic ventilation cooling, so the daily high temperature stage, the bed
