In order to explore the effects of combined application of winter green manure and organic-chemical fertilizer on nutrients，enzyme activities in reclaimed soil of rural homestead and rice yield，five treatments were designed，namely:winter wheat + 100% chemical fertilizer in rice season(control 1，CK1)，winter green manure + 100% chemical fertilizer in rice season(control 2，CK2)，winter green manure + 40% chicken manure combined with 60% chemical fertilizer in rice season(T1)；winter green manure + 40% earthworm manure combined with 60% chemical fertilizer in rice season(T2)；winter green manure + 40% rapeseed fertilizer combined with 60% chemical fertilizer in rice season(T3). The results showed that:(1)Compared with CK1，all winter green manure + 40% organic fertilizer combined with 60% chemical fertilizer treatments improved rice yield by 15.9%～37.4% for 2019 and 17.2%～29.6% for 2020. The yield increasement of T2 and T3 treatments was higher than that of T1.(2)Compared with CK1，all winter green manure + 40% organic fertilizer combined with 60% chemical fertilizer chemical fertilizer treatments improved the contents of soil total carbon，total nitrogen，available nitrogen，ammonium nitrogen + nitrate nitrogen(NH4++NO^3-)，available phosphorus and available potassium by 4.4%～13.2%，18.9%～24.5%，23.2%～37.6%，38.8%～83.2%，25.7%～59.8%，1.5%～9.8%，respectively. T3 was more conducive to improving soil total carbon，total nitrogen，available nitrogen，NH4+ + NO^3- contents. T2 was more conducive to improving soil available phosphorus and available potassium contents.(3)Compared with CK1，winter green manure + 40% organic fertilizer combined with 60% chemical fertilizer improved or significantly improved soil invertase，catalase，alkaline phosphatase activities as well as maintained or increased soil urease activity. T3 was more conducive to improving soil invertase activity. T2 was more conducive to improving soil urease and alkaline phosphatese activities.(4)Rice yield was significantly positively correlated with the contents of soil total carbon，total nitrogen，available nitrogen，NH4++NO^3-，available phosphorus，activities of soil invertase，catalase， alkaline phosphatese(P<0.05)，especially with the contents of total nitrogen，available nitrogen，activities of invertase， catalase. Therefore，in reclamation soil of rural homestead，winter green manure + 40% organic fertilizer combined with 60% chemical fertilizer could rapidly improve soil fertility so as to improve the rice yield. Among the three organic fertilizers，the effects of earthworm manure and rapeseed cake fertilizer on soil nutrients and enzyme activities were better than those of chicken manure.
