西兰花优化施肥及适宜微生物肥料筛选

The Optimized Fertilization and Screening of Suitable Microbial Fertilizer on Broccoli

以西兰花为试材,采用室内盆栽试验,设置了习惯施肥、优化无机肥与不同微生物肥配施处理,进行优化施肥措施筛选。结果表明:优化施肥处理提高西兰花株高、茎粗,地上部干重、鲜重,总干重、鲜重等生物学性状;提高土壤速效磷、速效钾含量;增加土壤微生物数量;促进植株吸收氮磷钾养分。施用含有细菌的微生物肥料能显著提高土壤细菌含量。与单施无机肥料相比,增施微生物肥料降低植株氮含量,提高钾含量;其中丰满囤生物肥效果较好。

Taking broccoli as test materials, using the habit fertilizer application and different optimized fertilization treatments,screening for the optimized fertilization measure by potted planting experiment indoor were studied. The results showed that the optimized fertization treatments improved the biological characters of broccoli, such as the plant height,stem diameter,dry and fresh weight ; improved the content of soil available phosphorus and available potassium; increased the number of soil mieroorganisms; improved the nutrients absorption of nitrogen phosphorus and potassium, etc. Applying microbial fertilizer containing bacteria could significantly increase the content of soil bacteria. Compared with just applying inorganic fertilizers, applying inorganic fertilizer and also applying microbial fertilizer, reduced plant nitrogen content,improved potassium content. The effect of ‘fengmantun＇ biological fertilizer was better than other microbial fertilizers.
