The results demonstrate that high concentrations of plastic film mulch had toxicity on wheat in accordance with variations in these physiological indexes of wheat.
结果表明,高质量分数塑料地膜的处理会对小麦早期幼苗的抗氧化酶系统产生毒害作用。
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.
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。
