摘  要：
于2006年田间试验中,以超级稻沈农265为试验材料,用无纺布和塑料薄膜覆盖育苗,研究其对苗床内温度、相对湿度及秧苗素质的影响。结果表明,相对于塑料薄膜,无纺布可有效调控床内的温度,使温度变化相对平缓,减少障碍性高温出现的机率,减少炼苗的次数,在一定范围内其保温效果与塑料薄膜相近;还可降低床内的相对湿度,使之与外界接近。在水稻育苗中,塑料薄膜覆盖有增加秧苗叶龄、株高和鲜重的作用,无纺布覆盖则可增加秧苗的干重和根系数量,能够提高秧苗的充实度,利于秧苗健壮、均衡生长和干物质积累。上述结果说明,在水稻育苗中无纺布是塑料农膜的理想替代材料。

摘  要：
In field test with super rice Shennong 265 as tested matirals in 2006,the non-woven fabrics and the plastic film was used to cover the rice seedling for studying their effects on temperature,relative humidity and seedling quality in seedbed.Results showed that,compared with the plastic film,the non-woven fabrics could effectively control the temperature in seedbed,made the temperature change relatively stable,reduced the appeared probability of handicap high temperature and decreased times of hardening seedling.In some range the temperature keeping effect by non-woven fabrics was closed to that by plastic film.It also decreased the relative humidity in seedbed,which could approach to that in outside.In raising rice seedling,plastic film coving could increase leaf age,plant height and fresh weight,while non-woven fabrics covering could enhance dry weight of seedling and roots and increase vitality of seedling which favored to growth and dry matter accumulation of seedling.It was concluded that non-woven fabrics was the ideal substitute materiel of plastic film in raising rice seedling.
