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、产值差异达显著水平
The results showed that the control effect of color film on tobacco weeds was 35.7% ~ 48.7%, and the yield of tobacco leaf was increased by 336kg / hm2. Silver gray film control tobacco weed effect of up to 2 2 1% ~ 2 3 5%, tobacco yield increased 15 3kg / hm2. The color yield of tobacco covered by color film and that covered by common film all reached the extremely significant level. Compared with silver film coverage, the difference of color yield reached a significant level and the difference of output value reached significant level. Silver gray film coverage compared with ordinary film coverage, tobacco production, the difference was significant output value
