摘　　要：以长茄一号为试材,在日光温室应用垄作栽培方法,以基肥仅施用氮磷钾复合肥为对照(CK),研究了减施30%基肥条件下,500 kg·667 m^(-2)(T1)、1000 kg·667 m^(-2)(T2)、1500 kg·667 m^(-2)(T3)3个不同生物酶尾料用量对茄子生育期、果实性状、产量以及土壤酶活性的影响,以期为日光温室茄子栽培合理应用生物酶尾料提供参考依据。结果表明,施用生物酶尾料后,茄子生育进程加快,采收期分别延长4.3 d、15.6 d、15.6 d,茄子产量比对照增加6.74%~13.14%,单果质量比对照提高5.54%~10.13%,叶绿素相对含量比对照提高12.40%~21.05%;土壤纤维素酶活性、蛋白酶活性、木聚糖酶活性、植酸酶活性分别比对照提高1.97%~45.40%、6.30%~17.61%、20.00%~41.22%、10.16%~67.20%。因此,施用生物酶尾料对茄子生长、改善茄子果实性状,提高茄子产量、增强土壤酶活性有较大作用,生物酶尾料的适宜用量为1000~1500 kg·667 m^(-2)。Reducing 30%compound fertilizer and using 100%compound fertiizer before sowing as control(CK),the effects of different biological enzymes residue treatments of 500 kg·667 m^(-2)(T1),1000 kg·667 m^(-2)(T2),1500 kg·667 m^(-2)(T3)on eggplants growth stage,fruit traits,yield and soil enzymes activity were explored with the experimental material of“Long Eggplant No.1”by the cultivation of ridge tillage in greenhouse,in order to provide the appropriate dosage of biological enzymes residue.The results showed that the addition of biological enzymes residue could prolong the harvest time of eggplants by 4.3 d,15.6 d,15.6 d in comparison with the CK.Compared with the control,addition of biological enzymes residue in soil increased eggplants yield by 6.74%-13.14%,single eggplant weight by 5.54%-10.13%,and relative chlorophyll content by 12.40%-21.05%,respectively.Applying biological enzyme residue in soil increased the activity of soil cellulase,protease,xylanase and phytase by 1.97%-45.40%,6.30%-17.61%,20.00%-41.22%,10.16%-67.20%,respectively.In summary,biological enzymes played an important role in improving the growth of eggplant,eggplant traits,eggplant yield and soil enzymes activity.The appropriate dosage of biological enzymes residue was 1000-1500 kg·667 m^(-2).
