摘要
以白榆种子为试材,研究了黑色地膜覆盖对白榆播种苗苗木生长量和除草效果的影响。结果表明:黑色地膜覆盖对白榆生长量有明显的促进作用,对1a生杂草数量有明显的抑制作用。
Using seeds of Ulmus pumila Linn. as material, the effect of weed control and seedling growth on sowing of Ulmus pumila Linn. under black plastic covering were studied. The results showed that the growth on sowing of Ulmus pumila Linn. had been obviously promoted and the growth of annual weeds had been obvious inhibited under black plastic covering by statistical analysis of plant height and ground diameter of Ulmus pumila Linn. , and the number of annual weeds on the field.
