水稻专用无纺布育秧效果研究

Study on the Effect of Rice Seedling Nursery with Non-textile

研究分析了水稻专用无纺布与传统塑料薄膜的育秧效果。结果表明 ,专用无纺布具微孔自然通风 ,膜内的最高温度较塑料薄膜覆盖低 9～ 1 2℃ ,而最低温度仅比塑料薄膜低 1～ 2℃ ,从而避免了塑料薄膜覆盖出现高温烧苗现象 ;用水稻育秧专用无纺布覆盖 ,无需人工通风炼苗 ,膜内温度变化平稳 ,出苗率、成秧率及秧苗素质显著优于塑料薄膜覆盖 ,秧苗生长均衡 ,不徒长 ,特别是青枯病、立枯病发病轻 ,有利于培育壮秧。

This paper studied the effect of non-textile on rice seedling nursery compared with traditional plastic film covering.The results showed that there was less seedling sunburn occurred by using of the non-textile,since with better ventilation the highest temperature in the shed of non-textile was 9～12 ℃ lower and the lowest temperature was only 1～2 ℃ lower than that in the shed of the plastic film.With the nontextile there was no need for manual ventilation,and the temperature change in the shed was stable,the emergence rate,developed rate and seedling quality were much better than that with the plastic film,the seedling growth was normal with less diseases,the increase of the yile could reach 7.67%.
