塑料簿膜育秧是防寒保温育秧的一种新形式。为了探索有色塑料簿膜育秧技术,自1979年起,文山州农科所与云南塑料厂和州气象台协作,分别在文山县攀枝花四队和大龙潭寨生产队进行早稻有色塑料簿膜育秧对比试验和复盖方式试验,两年来的试验结果表明:聚氯乙烯(PVC)深蓝色塑料簿膜育秧,增温快而平稳,有效积温高,透过过滤的蓝色短波光,促进秧苗整齐、健壮,叶片宽大,叶色深绿,茎基扁蒲,根系发达,移栽后返青快,分蘖早,成穗率高,穗大,粒多,早熟高产。优于其它颜色簿膜培育的秧苗。试验还表明,PVC深兰色簿膜棚式育秧,不论秧苗素质、长相长势、熟期抗性和产量结 Plastic film membrane seedlings is a new form of cold insulation seedlings. In order to explore colored plastic film seedling breeding technology, since 1979, Wenshan Prefecture Agricultural Branch and Yunnan Plastics Factory and the state meteorological station collaboration, respectively, in Wenshan Xian Panzhihua four teams and large Longtan village team for early rice colored plastic film filming contrast test And overlay test, the results of the two years showed that: PVC plastic film with dark blue plastic sheeting grew rapidly and steadily with high effective accumulated temperature, which facilitated the seedling to be neat and sturdy through the filtered blue short-wave light , Large leaves, dark green leaves, stem-based Bianpu, developed root system, transplanted back to green fast, early tillering, spike rate, spike, grain and more, early maturity and high yield. Better than other color film cultivation of seedlings. Test also showed that PVC dark blue film shed greenhouse seedlings, regardless of seedling quality, growth phase, ripening resistance and yield knot
