    摘要:

    为了确定生物有机肥料GSJ-1对连作马铃薯土壤养分、生长发育及病情指数的影响,本研究对连作马铃薯的根际和非根际土壤主要化学指标、马铃薯生长发育指标、块茎产量进行了测定,并且对收获连作马铃薯薯块疮痂病、黑痣病的病情进行了调查统计和分析。结果表明:相对于不施生物有机肥料的处理,生物有机肥料GSJ-1能显著改善土壤肥力状况,提高马铃薯生理指标和产量,并有利于减轻马铃薯土传病害(疮痂病、黑痣病)的发生。

    Abstract:

    To evaluate effects of bioorganic fertilizer GSJ1 on the soil main nutrients,growth characteristics and disease index of continuous cropping potato,an experiment was carried out to study the rhizosphere and non rhizosphere soil chemical index,plant growth index and the tuber yields of continuous cropping potato,and the disease of potato scab and rhizoctonia solani in field were observed and analyzed.The results showed that,compared with continuous cropping soil(CK),the bioorganic fertilizer GSJ1 application significantly increased soil fertility index,growth characteristics and tuber yield of potato,and effectively reduced the occurrence of the potato soilborne diseases(potato scab and rhizoctonia solani).
