无色的聚氯乙烯薄膜育秧,自五十年代起已在我省早稻育秧中逐步推广。它对防止烂秧,提高单产有显著效果,深受群众欢迎。近几年来随着光质对农作物生育影响研究的进展,国内外曾进一步开展有色薄膜育秧的研究。为了摸清有色膜对水稻秧苗质量的影响及其增产效果,供工业选型提供依据,我们于1977年在湖南省塑料研究所协助下进行了有色聚氯乙烯薄膜的早稻育秧试验,1978年我们又参加了全省的协作试验,对有色薄膜早稻育秧开展了进一步研究。现将两年试验结果作初步总结。 Colorless PVC film seedlings, since the 1950s has been in early rice cultivation in our province gradually promoted. It has a significant effect on preventing rotting seedlings and raising yield, and is well received by the masses. In recent years, with the progress of research on the effects of light quality on crop growth, research on colored thin film seedling raising has been carried out at home and abroad. In order to find out the effect of colored film on the quality of rice seedlings and its yield-increasing effect, it provided the basis for industrial selection. In 1977, with the help of Hunan Institute of Plastics, we conducted the experiment of early rice seedling raising with colored polyvinyl chloride film. In 1978, Also participated in the province’s collaborative experiment, the colored film early rice seedling carried out further research. The results of two years now make a preliminary summary.
