摘要：

摘 要: 通过田间小区试验,研究了稻草覆盖与间作三叶草与不同培肥配施后对茶园杂草总密度、优势杂草组成及生物多样性的影响。结果表明:稻草覆盖和间作三叶草降低了田间杂草的总密度,降低了优势杂草在群落中的相对密度,有利于维持田间杂草的生物多样性; 而与不同培肥配施后茶园杂草种类与各杂草相对丰度及多样性指数均存在差异,其原因可能是由于不同施肥造成各处理间土壤养分的不同,各种杂草的生长因而受其不同影响所致。

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.
