1.火窑子增温在育苗床底层挖通热道,前与火炉相连,后与烟囱接通,烟火通道沟上覆盖弧瓦,再覆营养土15~20厘米;利用煤、柴草等燃烧烟火经过通道,提高床土温度。此法适用于育苗期短的瓜类、豆类蔬菜育苗,这种育苗方式,有一定风险,不便控制和管理。2.酿热温床增温在育苗床内挖床坑,填厩肥、垃圾、稻草或其他可发酵有机物,通过发酵分解发出的热能,提高苗床土的温度。通过调节填酿热物的多少,改变床温高低和维持
1. Fire kiln sub-temperature raising in the nursery bed bottom digging hot runner, connected with the stove before, and connected to the chimney, smoke channel ditch cover arc tiles, and then cover the nutrient soil 15 to 20 cm; the use of coal, fireworks and other burning pyrotechnics After the passage, increase bed temperature. This method is suitable for nurturing short melons, beans, vegetable nursery, this nursery approach, there is a certain risk, inconvenient control and management. 2. stuffed hot hotbed warming digging bed nursery bed in the pit, fill manure, garbage, straw or other fermentable organic matter, through the decomposition of heat emitted by fermentation to improve the temperature of seedbed soil. By adjusting the amount of stuffing stuffy, change the bed temperature level and maintenance
