摘要:

探讨不同浓度下磷酸脲肥对马铃薯疮痂病和粉痂病发生情况的影响,为马铃薯土传病害防控研究提供新思路。本试验在混合土和带菌基质中设定5个不同处理的磷酸脲肥:①不施P2O5(CK);②施P2O5 43 kg/hm2 (T1);③施P2O5 86 kg/hm2 (T2);④施P2O5 172 kg/hm2 (T3);⑤施P2O5 344 kg/hm2 (T4),收获时调查病害发生情况,分析磷酸脲肥对2种病害发生的影响。结果表明混合土中施用磷酸脲肥6.8 g/株、带菌基质中施用磷酸脲肥3.4 g/株能有效降低马铃薯疮痂病的发生,而混合土和带菌基质中施用磷酸脲肥对粉痂病的发生均无影响。

Abstract:

The study aims to explore the effects of urea phosphate fertilizer of different concentrations on the occurrence of potato scab and powdery scab, so as to provide a new idea for the prevention and control of potato soil borne diseases. In this experiment, five urea phosphate fertilizer treatments were set in the mixed soil and bacterial matrix, including P2O5 (CK), P2O5 43 kg/hm2 (T1), P2O5 86 kg/hm2 (T2), P2O5 172 kg/hm2 (T3), and P2O5 344 kg/hm2 (T4). The occurrence of diseases was investigated at harvest, and the effects of urea phosphate fertilizer on the occurrence of the two diseases were analyzed. The results showed that the application of urea phosphate fertilizer 6.8 g/plant in mixed soil and 3.4 g/plant in bacterial matrix could effectively reduce the occurrence of potato scab, while the application of urea phosphate fertilizer in mixed soil and bacterial matrix had no effect on the occurrence of powdery scab.
