| 摘 要： | 为了明确不同覆盖方式对甜玉米田杂草出苗生长的抑制效果,寻求更安全环保的控制甜玉米田杂草发生危害的方法,本研究采用大田试验,在甜玉米移栽前,将不同厚度的玉米秆、水稻秆及1层黑色地膜均匀覆盖于小区内.结果显示,处理后20、40 d,黑色地膜能完全抑制甜玉米田杂草的生长,且能显著提高甜玉米产量,增产率为45％;不同厚度的稻秆和甜玉米秆覆盖能够控制杂草的发生,且覆盖厚度越厚,控草效果越好,顺序为稻秆20 cm＞甜玉米秆20 cm＞稻秆10 cm＞甜玉米秆10 cm.秸秆覆盖均能显著增加甜玉米的产量,且甜玉米秆20 cm处理的甜玉米产量最高,但彼此间无显著性差异.

| Abstract: | The suppressive effect of different mulching treatments on weed germination in sweet corn,as a safe and environmentally benign method for controlling weeds,was explored.Treatments consisted of rice straw much of different thickness,sweet corn straw and a layer of black plastic film uniformly covering the experimental plots.Black plastic film completely controlled weeds and significantly increased sweet corn yield by 45％ after covering the soil for 20 or 40 days.Mulches of both rice and sweet corn straw controlled weeds in relation to their thickness,in the following order：rice straw 20 cm ＞ sweet corn straw 20 cm ＞ rice straw 10 cm ＞ sweet corn straw 10 cm.Straw mulches also increased sweet corn yield,the highest being obtained when the 20 cm sweet corn straw mulch was used,although it did not differ from the yield obtained with the other mulches. |
