一种植物源组方对山楂果园杂草的除草活性研究

Study on Herbicidal Activity of A Plant Source Formula in Hawthorn Orchards

以冬凌草、款冬花、翼首草和木通制成的组方为研究对象,通过除草率的测定,比较该组方对山楂果园中杂草的克生作用。结果表明,该组方对果园中萌芽期和营养生长期杂草有较为理想的抑制表现。冬凌草、款冬花、翼首草和木通植物资源丰富,又有药用经济价值,可考虑发展为套种优先植物,抑制杂草的同时又能为果园创收。

Taking the Rabdosia rubescens ,Tussilago farfatra L.,Pterocephalus hookeri and A kebia quinata （Thunb.） as the research object, the allelopathy of the formula towards the weeds in the hawthorn orchards was tested by testing the weeding ratio. The results showed that this formula had a positive effect on the inhibition of weeds. The four herbs were in abundant resources as well as had medicinal and economic value, therefore they could be considered as the priority interplanting plants, inhibiting weeds while revenue.
