摘要:: 以瓜列当种子为试材，采用不同浓度的磷素溶液（1×10-4、3×10-4、5×10-4、7×10-4、9×10-4、1×10-5、3×10-5、5×10-5、7×10-5、9×10-5、1×10-6、3×10-6、5×10-6、7×10-6、9×10-6、1×10-7、3×10-7、5×10-7、7×10-7、9×10-7）对预培养的瓜列当种子进行处理，研究了磷素对瓜列当种子发芽率及瓜列当与加工番茄寄生的关系。结果表明：在磷素溶液为1×10-4、9×10-4、1×10-5、3×10-5、1×10-6浓度下瓜列当发芽率较高，对瓜列当发芽有促进作用，在磷素溶液为7×10-6、9×10-5、9×10-6、9×10-7浓度下瓜列当发芽率较低；在1×10-5和9×10-5级别浓度下瓜列当寄生率最低，且差异不显著，能较好的抑制瓜列当的寄生。因此，10-5浓度的磷在促进瓜列当诱杀发芽和减少寄生方面有很好的应用前景。

Abstract:: Orabanche aegyptiaca Pers.seed was used as material,the preculture of Orabanche aegyptiaca Pers.seed were conducted with different concentrations of phosphorus solution (1×10-4,3×10-4,5×10-4,7×10-4,9×10-4,1×10-5,3×10-5,5×10-5,7×10-5,9×10-5,1×10-6,3×10-6,5×10-6,7×10-6,9×10-6,1×10-7,3×10-7,5×10-7,7×10-7,9×10-7),the regulation of phosphorus to Orabanche aegyptaica Pers.seed germination and O.aegyptiaca Pers.-tomato parasitic relationship were studied．The results showed that the concentrations of P solution of 1×10-4,9×10-4,1×10-5,3×10-5,1×10-6 level had high germination rates and the obvious stimulative actions to Orabanche aegyptaica Pers.seed,when the concentrations of P solution of 7×10-6,9×10-5,9×10-6,9×10-7 level,the germination rate was low,when the concentrations of P solution of 1×10-5 and 9×10-5 level,the germination rate was the lowest,they could generate inhibitation in parasitism.It was concluded that the concentrations of P solution of 10-5 had very good application prospect in promoting trap killing and germination of Orabanche aegyptaica as well as reducing the parasitism rate.
