中文摘要:
      采用田间小区试验,以溶磷解钾微生物菌剂(功能菌为巨大芽孢杆菌和胶质芽孢杆菌)和"冀张薯12""紫色马铃薯""大西洋"3个品种马铃薯为研究对象,探讨了在张北冷凉坝上地区施用微生物菌剂对不同品种马铃薯产量、品质、土壤速效磷钾以及土壤磷酸酶活性的影响。结果表明:施用微生物菌剂可以显著增加3个品种马铃薯的产量(P<0.05),其中"冀张薯12"产量增幅最大为24.54%,其他2个品种产量平均增幅仅为6.96%)可以改善马铃薯的品质,尤其是紫色马铃薯,其Vc、可溶性蛋白质和可溶性糖含量均显著提高,增幅分别为320.21%,29.40%,7.12%(P<0.05)。此外,菌剂施用调控着整个生育期土壤速效磷钾的含量和相关土壤酶活性,种植"大西洋"和"冀张薯12"的土壤施用菌剂后速效磷钾含量高于对照且在中后期达到显著水平,同时提高了土壤酸性和碱性磷酸酶的活性,平均增幅为37.52%和32.30%。总之,溶磷解钾微生物菌剂适用于冷凉张北坝上地区马铃薯种植,且对"冀张薯12"的促生效果最为明显。
英文摘要:
      This field experiment was conducted with different varieties of potato ("Atlantic" "Purple Potato" "Ji Zhang Potato 12") in Zhangbei area to explore the effects of microbial inoculants with P and K-solubilizing bacteria (MI containing the effective strains of Bacillus megaterium and Bacillus mucilaginous) on potato yield, quality, soil available P, K and soil phosphatase. The results showed that the application of microbial inoculant increased the yields of three varieties of Potato (P<0.05), especially for "Ji Zhang Potato 12"by 24.54%, while the average increase of yield was only 6.96% for the other two. Moreover, the quality of potatoes was improved, especially for Purple Potato. The contents of Vc, soluble protein and soluble sugar were significantly increased by 320.21%, 29.40% and 7.12%, respectively (P<0.05). In addition, the application of microbial inoculant regulated the contents of available phosphorus and potassium in the soil and the related soil enzymes activities during the whole growth period. The available P and K contents of the soil cultivated with the cultivars of "Atlantic"and "Ji Zhang Potato 12"were higher than those of CK, and reached a significant level at the middle and late growing stages. At the same time, the activities of soil acid and alkaline phosphatase were increased, with an average increase of 37.52% and 32.30% respectively. Overall, P and K-solubilizing microbial inoculant is suitable for the growth of potato in Zhangbei area, especially for "Ji Zhang Potato 12".
