摘要
以干制辣椒"北星五号"为试材,采用小区试验与大田试验相结合的方法,设定增施微生物菌肥、增施土壤修复剂、同时施用微生物菌肥与土壤修复剂、不增施微生物菌肥和土壤修复剂等4个处理的小区试验;同时于2018年和2019年在辣椒重茬连作地开展大田示范试验,研究微生物菌肥和土壤修复剂对重茬连作干制辣椒生长及抗病性的影响,以期为解决干制辣椒连作障碍提供有效技术措施。结果表明:1)增施微生物菌肥和土壤修复剂可以促进辣椒生长,株高、茎粗等指标显著高于对照;2)增施微生物菌肥和土壤修复剂可以改善辣椒品质,辣椒单果质量、可溶性糖含量显著增加;3)增施微生物菌肥增产效果最显著,2年的大田示范试验验证了增施微生物菌肥的增产效果;4)增施微生物菌肥和土壤修复剂可以降低土壤盐度,提高土壤微生物含量,但增施微生物菌肥对土壤的改善作用效果更为显著。整体来看,增施微生物菌肥是解决干制辣椒重茬连作,实现土壤改良,增产增效的有效措施。
In order to provide effective technical measures for resolving continuous cropping obstacle in dry pepper,‘Beixing No.5’pepper was used as material,the effect of microbial fertilizer and soil amendment on growth and anthracnose resistance yields in monoculture were studied.The experiment was designed to be increasing application microbial fertilizer,increasing application soil amendment,simultaneous use of microbial fertilizer and soil amendment,no microbial fertilizer and soil amendment four treatments to stress dry pepper cultivation.The demonstration trial was developed in continuous cropping land of dry pepper in 2018 and 2019.The results showed that the treatment of increasing application microbial fertilizer and increasing application soil amendment all could promote growth of pepper,height and stem diameter of pepper significantly higher than control treatment.The treatment of increasing application microbial fertilizer and increasing application soil amendment all could improve pepper quality,single fruit weight and soluble sugar content significantly increased,compared with control treatment.Increasing application microbial fertilizer significantly increased yield,demonstration trials for two years also verified the yield increasing effect of microbial fertilizer on dry pepper.The treatment of increasing application microbial fertilizer and increasing application soil amendment all could induce soil salinity and increase soil microbial content,but the treatment of increasing application microbial fertilizer showed better in soil amelioration.On the whole,increasing application microbial fertilizer was an effective measure to solve continuous cropping obstacle,improve soil and increase yield.
