    摘要:

    以提高胶冻样芽孢杆菌在土壤中的存活率、减缓其衰亡速率，延长存活时间，提高其对土壤难溶性钾的解钾效率为目的，利用不同种类的秸秆生物质炭与胶冻样芽孢杆菌进行复配筛选。通过室内培养试验发现，中性小麦秸秆炭可作为胶冻样芽孢杆菌较理想的载体。当土壤培养35天后，土壤速效钾含量在施用炭基解钾菌肥条件下较空白提高了28.53% ，较小麦秸秆炭和纯菌液处理分别提高了20.75%、13.41%。纯菌液处理土壤中胶冻样芽孢杆菌的菌落数从1.1×109个/g土降为9.0×105个/g土，而炭基解钾菌肥处理则为1.4×107个/g土。田间施用炭基解钾菌肥能够提高番茄植株和果实中的全钾含量；提高番茄产量和品质，显著提高番茄Vc含量，降低硝酸盐含量。因此，中性小麦秸秆炭与胶冻样芽孢杆菌的复配能够提高菌剂的存活率，有效促进土壤中矿物态钾的释放。

    Abstract:

    Experiments were conducted by compounded various straw biochars and Bacillus mucilaginosus in order to select the optimal carrier to improve the survival rate of Bacillus mucilaginosus, slow its senescence rate, prolong its survival time in soil, and promote the releasing efficiency of soil insoluble potassium. Incubation experiments showed that neutral wheat straw biochar could be used as the ideal carrier for Bacillus mucilaginosus. After 35-d incubation, the content of soil available potassium of biochar-based potassium-releasing fertilizer was 28.53%, 20.75% and 13.41% higher than CK, wheat straw biochar and microbial liquid treaments, respectively. Although the quantities of the Bacillus mucilaginosus both in microbial liquid treatment and biochar-based potassium-released fertilizer treatment were significantly decreased, the decreased rate in biochar- based potassium-released fertilizer treatment (1.0×109 cfu/g to 1.4×107 cfu/g) was lower than microbial liquid treatment (1.1× 109 cfu/g to 9.0×105 cfu/g). Field experiments showed that biochar-based potassium-released fertilizer could significantly increase total potassium contents in tomato plants and fruits, increase the yield and quality of tomato, promote the content of vitamin C, and decrease nitrate content. These results indicate that compound neutral wheat straw biochar and Bacillus mucilaginosus can improve the survival rate of inoculant and promote effectively the release of mineral potassium from soil.
