采用盆栽定量等氮还田的方法，研究番茄秸秆直接还田和堆肥还田对番茄生长、产量、果实品质、土壤碳氮含量及
酶活性的影响。结果表明：番茄秸秆直接还田处理在还田60 d 内对番茄植株生长有化感抑制作用，抑制作用在60 d 后减弱，
还田110 d 后能促进番茄植株生长，显著提升果实品质，提高土壤全碳、全氮含量。番茄秸秆堆肥还田处理能够持续促进番
茄植株生长，改善果实品质，显著提高番茄产量，土壤全碳、全氮含量及C/N 显著提高，脲酶、蔗糖酶活性显著提高。在生
产中番茄秸秆堆肥可直接作为肥料施用，且肥效优于鸡粪，番茄秸秆直接还田则需要至少60 d 的腐解才能减弱对番茄生长
的抑制作用。
Adopting the method of returning nitrogen quantitatively in pot cultivation，this paper studied
the effects of returning tomato straw directly to field and returning it to field after compost treatment on tomato
growth，yield，fruit quality，soil carbon and nitrogen contents，and enzyme activity. The results showed that the
direct returning method could inhibit tomato plant growth within 60 days after returning to field. The Inhibition was
weakened 60 days afterward. After 110 days directly returning to field，the tomato plants growth was stimulated，
fruit quality was significantly improved and contents of total carbon and total nitrogen，C/N ratio were all increased.
Tomato straw compost continued to promote the growth of tomato plant，tomato yield was significantly increased，
and contents of total carbon and total nitrogen，C/N ratio and activities of urease and sucrase were all significantly
increased. In production，tomato straw compost can be directly applied as fertilizer，and its fertilizer efficiency is
better than that of the chicken manure. But，the direct returning of tomato straw to field requires at least 60 days
decomposition period to decrease its inhibition effect on tomato growth.
