Control of Fusarium wilt by wheat straw is associated with microbial network changes in watermelon rhizosphere

Abstract Straw return is an effective strategy to alleviate soil-borne diseases. Though watermelon Fusarium wilt is a severe soil-borne disease, the effect of wheat straw on the disease remains unclear. Thus, we investigated the effects of wheat straw on soil bacterial and fungal communities by addi...
