摘要
设计了5个处理,研究了施用沼肥对红心萝卜生长的影响。结果表明,沼渣(R)处理产量为59096kg/hm^(2),较沼渣+沼液(RS)处理的产量高4002 kg/hm^(2),增幅7.3%,较猪粪处理(M)产量高6670 kg/hm^(2),增幅12.7%。RS处理相对M处理增幅5%。R和RS处理产量明显高于空白对照(CK)和化肥(CF)处理。红心萝卜出苗后通过3次不同时间段分别对R、RS和M 3个处理淋施不同浓度的沼液,与CK和CF 2个处理相比,R、RS和M 3个处理的萝卜长势、适口期及维生素C含量均优于CK和CF 2个处理。
Five treatments were designed to study the effect of marsh fertilizer on the growth of radish.The results showed that the yield of biogas residue(R)treatment was 59096 kg/hm^(2),which was 4002 kg/hm^(2)higher than that of biogas residue+biogas slurry(RS)treatment,with an increase of 7.3%,and 6670 kg/hm^(2)higher than that of pig manure(M)treatment,with an increase of 12.7%.RS treatment increased by 5%compared with M treatment.The yield of R and RS treatment was significantly higher than blank control(CK)and chemical fertilizer(CF)treatment.After the emergence of radish,three treatments R,RS and M were treated with biogas slurry at different concentrations for three times in different time periods,respectively.Compared with CK and CF,the growth,palatability and vitamin C content of radish in R,RS and M treatments were better than those in CK and CF treatments.
