摘 要：为了提高常熟地区甜椒生产能力及充分利用农业废弃物消解产物，开展了蚯蚓粪浸出液浸种育苗及替代化肥施用于甜椒的田间试验，结果表明，当蚯蚓粪浸出液浓度为75%时，甜椒种子的发芽率最高，甜椒苗的株高和根长也最大;当蚯蚓粪浸出液替代量为50%时，甜椒产量最高，比常规化肥处理增产34.2%。因此，在实际生产中，蚯蚓粪浸出液替代化肥比例为50%时最佳，既可降低生产成本，又提高了甜椒产量。

Abstract：In order to improve the production capacity of sweet peppers in the region and make full use of the digestion products of agricultural wastes，the experiment applied to the sweet peppers by soaking seedlings and replacing fertilizers with the manure extract. The results showed that when the concentration of the manure extract was 75%，the sweet pepper seeds The germination rate was the highest;when the concentration of cockroach dregs was 75%，the plant height and root length of the sweet pepper seedlings were the highest;when the replacement amount of cockroach dregs was 50%，the yield of sweet pepper was the highest，which was 34.2% higher than that of conventional fertilizer treatment. Therefore，in actual production，when the ratio of manure extract to the chemical fertilizer is 50%，the production cost can be reduced and the yield of sweet pepper can be increased.
