The effects of different straw return treatments, including no straw (CK), straw crushed (SC), straw manure (SM), straw biochar (SB), straw crushed+straw manure (SC+SM), straw crushed+straw biochar (SC+SB), and straw manure+straw biochar (SM+SB) on soil properties, yield and quality of radish (Raphanus sativus L.) were studied by field experiments. The results showed that all straw return treatments significantly increased the contents of soil organic matter and total nitrogen, but had different effects on the content of soil available potassium, among them, SC+SM, SC+SB and SM+SB significantly increased the content of soil available potassium while SC, SM and SB had no affects. Straw return had different effects on biomass and SPAD value of radish, which were significantly lower under SC+SM while significantly higher under other straw return treatments than CK. The quality of radish after straw return was significantly improved compared with CK, the contents of vitamin C, soluble sugar, total phenol and flavonoid of radish treated with straw return were significantly higher than CK, and there was no difference among the straw return treatments. Straw return significantly reduced nitrate content and increased soluble protein content of radish, among them, the effects of SC+SM, SC+SB and SM+SB were more prominent, with nitrate content reduced by 36.04%-40.63% while soluble protein content increased by 41.70%-56.11%; followed by SC, SM and SB, nitrate content decreased by 15.15%-22.58% while soluble protein content increased by 16.61%-25.11%. Radish FRAP values of straw return were significantly higher than CK, but DPPH values were different, among them, DPPH values of radish were significantly higher under SM, SC+SM, SC+SB and SM+SB than CK, while DPPH values of radish in SC and SB were close to CK. SC, SM, SB, SC+SB and SM+SB all improved soil fertility, crop yield and product quality, among them, SC+SB and SM+SB were better in reducing radish nitrate content. In conclusion, SC, SM and SB were recommended for conventional vegetable production, while SC+SB and SM+SB recommended for vegetables with high nitrate accumulation, such as leafy vegetables.
