中文摘要：

生物有机肥是一种集有益微生物和有机肥优点为一体的新型肥料,能更好地让有益微生物在土壤中定植和生长。本研究针对马铃薯连作障碍问题,探索几种生物有机肥对马铃薯连作土壤生物性状、产量及品质的影响。试验以威芋5号原种为材料,在同等化肥用量的基础上,增施等量不同品种的生物有机肥,测定其出苗率、农艺性状、产量及品质、土壤生物性状等。结果表明：施用生物有机肥对马铃薯的农艺性状、出苗率、土壤养分及微生物群落结构、产量以及薯块品质均有改善作用。其中GZ-I处理增产效果最明显,增产率为52.26%,并且GZ-I处理可以明显地提高细菌与真菌的比值（B/F）,其B/F较对照提高5.67倍。GZ-III处理提质效果最明显,马铃薯薯块中淀粉、还原性糖以及Vc含量最高,分别较对照提高0.68倍、1.64倍、0.41倍。施用不同生物有机肥均可提高马铃薯土壤的养分含量,改善土壤肥力水平,其中GZ-III处理的改土效果最明显,可以明显增加土壤中的有效养分含量。因此,生物有机肥可以提高连作区马铃薯的产量和品质,并对土壤有明显的改良作用,其中GZ-I处理的增产效果最好,GZ-III处理的提质和改土效果最好。

英文摘要：

Bio-organic fertilizer is a new type of fertilizer which combines the advantages of beneficial microorganism and organic fertilizer, thus can promote the colonization and development of beneficial microorganism in soil. A field experiment was conducted to disclose the effects of different bio-organic fertilizers on potato production and soil biochemical characteristics in order to overcome the obstacle of potato continuous cropping. In this study, the emergence rates, agronomic traits, yields and qualities of Weiyu 5, a potato variety, as well as soil biological properties were compared under the same amounts of chemical fertilizer and of different bio-organic fertilizers. The results showed that bio-fertilizers improved potato production and soil nutrients and microbial community. Compared with CK（only chemical fertilizers）, GZ-I treatment was the best in increasing potato yield, increased by 52.26%, and also increased the ration of bacteria to fungus（B/F） by 5.67 times. GZ-III was the best in improving potato quality, which had the highest contents of starch, reducing sugar and Vc, increased by 0.68, 1.64 and 0.41 times, respectively. Bio-fertilizers improved soil nutrient contents and soil fertility, in which GZ-III was best. In general, bio-organic fertilizer can improve soil quality and increase the yield and quality of potato under continuous cropping, GZ-I is the best in promoting yield and CZ-III is the best in promoting soil and potato qualities.
