摘要
针对德州市露地辣椒主产区偏施化肥、土壤板结、肥力不高、辣椒产量偏低、种植效益偏少的问题,开展配施蚯蚓粪对辣椒生长和根际土壤微环境的影响以及产量效益的分析,以期为辣椒生产提供参考。结果表明,配施蚯蚓粪,辣椒农艺性状明显增加,根际土壤酶活性提高,根际微生物数量增加,B/F增大,根际微环境改善,辣椒产量显著提高,其中基施硫酸钾型复合肥1500 kg/hm^(2)+蚯蚓粪(200 g/穴,即13341 kg/hm^(2))表现最好,与对照相比,辣椒产量增加了86.38%,净收益增加了132.02%。
In view of the problems of excessive chemical fertilizer application,soil compaction,low fertility,low yield of chili and low planting benefit in main open field pepper producing areas in Dezhou City,the effects of earthworm manure application on chili growth and rhizosphere soil microenvironment and yield benefit were studied and analyzed,in order to provide reference for chili production.The results showed that earthworm manure combined with earthworm manure significantly increased the agronomic traits of chili,rhizosphere soil enzyme activity,rhizosphere microbial number,B/F,rhizosphere microenvironment and yield of chili significantly increased.Basal application of potassium sulfate compound fertilizer 1500 kg/hm^(2)+wormcast(200 g/hole,namely 13341 kg/hm^(2))showed the best performance.Compared with the control,chili yield increased by 86.38%and net income increased by 132.02%.
