液态地膜对玉米生长及产量的影响

Affects of Liquid Film on Growth and Yield of Maize

液态地膜是一种新型的土壤增温保水覆盖材料。通过田间试验比较研究了液态地膜与其它覆盖措施对玉米各生长期性状和产量构成的影响。结果表明：在山西天镇县使用液态地膜能使玉米的出苗率提高17％，促进玉米的生长与发育，提高玉米产量，较对照高出17．4％。液态地膜覆盖能显著提高土壤温度，5cm土壤温度高于对照4～5℃，10～15cm土壤温度高于对照2～3℃。液态地膜结合大垄沟种植玉米在当地是非常适宜的。

Liquid Film is a new material that is covered on the soil for containing water and increasing temperature of the soil. Experimentation in the field shows the effects to the growth and yield of the Maize between the Liquid Film and other coverage measures. Results showed that in Tianzhen of ShanXi Province Liquid Film enables a higher seedling growth rate 17% than the compartment, It also can promote growth and development of plants then increase yield of Maize and 17.4% to the compartment. The temperature of soil could be increased lremarkably when Liquid Film was used, respectively 4 -5℃ in 5cm soil depth and 2 -3℃ in10 - 15cm soil depth. And the results showed that it is available to use Liquid Film with Maize planting in Tianzhen.
