摘　　要：行内施用不同用量和配比的生物秸秆,进行茄子栽培试验。结果表明,以每666.7m2施用4 000～4 800 kg秸秆与8 kg菌种、4 kg疫苗组配效果较好。与常规施肥相比,土壤有机质提高1个百分点,速效氮和速效钾分别提高61.6 mg/kg和20.6 mg/kg;每666.7m2蚯蚓数量增多309～505条,增幅为43.8%～71.6%;增产幅度为4.3%～10.6%;果实硝酸盐平均含量低158 mg/kg,降幅为19.2%。综合生物学性状、产量、硝酸盐含量和效益等方面考虑,每666.7m2施菌种8 kg、疫苗4 kg、玉米秸秆4 000 kg的效果较好。The cuhivation test was conducted for eggplant with different application amount and formula of biological straw in row. The results showed that the effect was better when using 4 000 -4 800 kg straw per 666.7m/ combined with 8 kg biological strains and 4 kg vaccinum. Compared to common fertilization, the soil organic matter content increased one percentage point, and the content of available nitrogen and potassium in- creased by 61.6 mg/kg and 20.6 mg/kg respectively; the number of earthworm increased 309 ~505 with the amplitude as 43.8% - 71.6% ; the eggplant yield increased by 4.3% ~ 10.6% ; the nitrate content in eggplant fruit decreased by 158 mg/kg with the decreasing amplitude as 19.2%. Comprehensively considered bi- ological characters, yield, nitrate content and benefit, 4 000 kg corn stalk per 666.7m2 combined with 8 kg biological strains and 4 kg vaccinum was the best for eggplant.
