水稻有色打孔塑料薄膜棚式育秧效果研究

The Effect of Raising Paddy Rice Seedlings by Shed Covered With Holed, Coloured Plastic Film

本文通过多年对各种颜色塑料薄膜打孔与无孔,棚架式和平铺式的水稻育秧试验研究,结果表明:利用深蓝色打孔膜棚式育秧,其膜内温、湿效应较好,光质效应也好,秧床松软透气,有利于培育壮秧,促使水稻早熟、高产。此外,还能简化秧田管理,节省秧田用工,提高经济效益。这些资料对水稻育秧有一定的参考价值和现实意义。

Through mang years of researches on raising paddy rice seedlings by different methods including the spread of shed covered with different coloured plastic film, both with and without holes, the author indicated that in the raising of paddy rice seedlings by shed covered with holed deep blue colour plastic film, the inside temperature and humidity are better, and the light quality also is suitable. The seedling bed is soft and well ventilated. It is good for raising strong seedlings to produce early maturing and high yields. In addition, it can simplify the management of seedling beds and save manual labour. As a result, the economic benefit can be increased. Hence this tecnique has practical significance in raising paddy rice seedlings.
