对银灰膜、配色膜覆盖控制烟田杂草生长进行了初步研究 ,结果表明 :配色膜控制烟田杂草效果达35 7%～ 48 7% ,烟叶产量提高 336kg/hm2 。银灰膜控制烟田杂草效果达 2 2 1%～ 2 3 5 % ,烟叶产量提高 15 3kg/hm2 。配色膜覆盖与普通膜覆盖烟叶产量、产值差异均达极显著水平 ,配色膜覆盖与银灰膜覆盖相比 ,产量差异达极显著水平 ,产值差异达显著水平。银灰膜覆盖与普通膜覆盖相比 ,烟株产量。

The effect of silver gray film and match color film mulching on control of weeds in tobacco fields was studied.The results showed that the effects of match color film mulching was 35.7% 48 7% and tobacco yield increased by 336 kg/hm 2, while the effect of silver gray film mulching was 22.1% 23 5% and tobacco yield increased by 153kg/hm 2.The difference of tobacco yield and output value between match color film and common film mulching was highly significant.The difference of tobacco yield between match color film and silver gray film mulching was highly significant and that of output value was significant.The difference of yield and output value between silver gray film and common film mulching was significant.
