Abstract:

Abstract: Plot trial was carried to study the effects of intercropping white clover and straw mulching with different fertilization on weeds density, dominant weed species and weed biodiversity. The results showed that total weed density was low, dominant weed species were less important and the weed biodiversity was high after intercropping white clover and straw mulching. With different fertilization, the species , relative abundance of weeds and the diversity indices are changed,. It is due to the different amounts of available soil nutrients which maybe have different impacts on the growth of different weeds.
