随着新农村建设和现代农业的快速发展,大棚蔬菜发展又进入新一轮高峰。但新发展的大棚多由粮田直接调整而来,存在土壤肥力较差,不能满足蔬菜生产优质、高产的需要;其次新菜农栽培管理技术水平较低,投入盲目性大,易于造成氮磷钾等养分供应失调,土传病虫害发生严重等土壤障碍的问题。因此,科学引导新菜农对新大棚菜田土壤培肥和管理,成为急需解决的技术问题。土壤培肥改良的主要手段是增施有机肥。现将有机肥种类、特点及施用介绍如下。农家肥:包括粪肥、饼肥、绿肥、秸秆还田、泥肥、堆肥、沤肥、厩肥、沼气肥等,具有原材料来源广泛、易于就地取材、价格低廉、施用后不仅
With the new rural construction and the rapid development of modern agriculture, greenhouse vegetable development has entered a new round of peak. However, newly developed greenhouses are mostly directly adjusted from the grain fields, resulting in poor soil fertility, which can not meet the needs of high-quality and high-yielding vegetables. Secondly, the cultivation and management techniques of new vegetables are relatively low, Such as nutrient imbalances, soil-borne diseases and pests serious soil barrier problems. Therefore, scientifically guiding new farmers to soil fertility management and management in new sheds has become an urgent technical problem to be solved. Soil fertility improvement is the main means of increasing organic fertilizer. Now organic fertilizer types, characteristics and applications are described below. Manure: including manure, cake fertilizer, green manure, straw, mud, composting, fertilizer, manure, biogas fertilizer, with a wide range of sources of raw materials, easy to local materials, low prices, after the application of not only
