以‘黑彤K-8’西瓜为试材，通过大田试验研究了 CK（不施肥）、CF（习惯施肥）、VC（蚯蚓粪）和VC+CF（蚯蚓粪和化肥各提供50%的氮）等处理对西瓜品质及根际土壤理化性状的影响。结果表明：同CF处理相比，VC+CF处理明显降低了根际土壤pH值，显著提高了根际土壤速效N、P、K含量以及EC值；明显增强了脲酶、过氧化氢酶、多酚氧化酶和蔗糖酶活性，其中脲酶活性分别比CK、CF和VC处理提高51.13%、17.19%和12.84%。此外，VC+CF处理还显著提高了西瓜产量，且明显改善了西瓜品质。与VC+CF处理相比， VC处理对西瓜根际土壤理化性状及产量、品质的影响较小。因此，蚯蚓粪与化肥配施对西瓜的作用效果更佳，是比较理想的施肥措施。

Vermicompost was an important organic amendment that regulated the functional properties of agricultural systems. However, there was little information on the effect of vermicompost co-applied with inorganic fertilizer on the ecological environment at rhizosphere soil and yield of watermelon. Considering the benefits of vermicompost, a field experiment was conducted to determine whether the vermicompost co-applied with inorganic fertilizer benefits the ecological environment of watermelon rhizosphere soil. There were four treatments in the field experiment, CK (neither urea nor vermicompost was applied), CF (100%of nitrogen was provided by urea), VC (100%of nitrogen was provided by vermicompost), and VC+CF (50%and 50%of nitrogen was provided by vermicompost and urea, respectively). The study was conducted to determine the effects of vermicompost co-applied with inorganic fertilizer on soil phy-chemical properties, enzyme activities at rhizosphere soil and yield as well as quality of watermelon. The results showed that compared to the CF treatment, the VC+CF treatment significantly decreased the pH value and apparently increased the contents of available N, available P and available K, as well as EC value in rhizosphere soil. At the same time, the activity of urease enzyme, catalase enzyme, polyphenol oxidase enzyme and invertase enzyme in VC+CF treatment was also improved, showing 51.13%, 17.19% and 12.84% increases on urease enzyme activity than in CK, CF and VC treatments, respectively. Additionally, the VC+CF treatment also significantly improved the yield and quality of watermelon. In comparison with the VC+CF treatment, the VC treatment had less effect on soil biological characteristics and yield as well as quality of watermelon. As a result, vermicompost co-applied with inorganic fertilizer had better effect on watermelon, which was an ideal fertilization practices.
