不同规格地膜对鲜食玉米和大豆生长发育的影响

The Effects of Different Specifications of Plastic Film on the Growth of Fresh Corn and Soybean

为探索适合在如东县推广的地膜科学使用技术,选用6种不同规格的地膜对鲜食玉米和大豆进行试验,以裸地为对照。结果表明,当低温影响较大时,推荐使用白色普通地膜;干旱影响较大时,推荐使用黑色普通地膜。在种子萌发期,使用白色普通地膜可以明显提升发芽率。在鲜食玉米生长期,推荐白色加厚地膜;全生物降解黑色地膜能有效提升鲜食大豆株高,但会影响新叶萌发。

In order to explore the scientific technology of plastic film suitable for promotion in Rudong county,six different specifications of plastic film were selected for planting experiments on fresh corn and soybeans,with bare land as the control.When the impact of low temperature was significant,it was recommended to use white ordinary plastic film.When the impact of drought was significant,it was recommended to use black ordinary plastic film.During the seed germination period,using white ordinary plastic film could significantly promote the germination rate.During the growth period of fresh corn,it was recommended to use thick white plastic film.Fully biodegradable black plastic film could effectively increase the height of fresh soybean plants,but it affected the germination of new leaves.
