鉴于目前京郊塑料大棚迅速发展的情况,在蔬菜生产中研究用加温棚育苗,对于改革现有育苗方式(阳畦或改良阳畦育苗),培育大批壮苗、缩短苗龄、降低成本、提高安全性等,具有重要意义。本文介绍我们在塑料棚中水暖土壤加温培育果菜类幼苗的效果。试验在四季青公社远大大队试验站小型塑料棚(棚宽4.3米,长30米)内进行。热源为卧式小锅炉,容积50公斤炉,顶与地面平,出水管为2寸铁管,高出地面20厘米,散热管为埋入土中的1寸硬质塑料管,回水流入锅炉,整套装置见图1。田间试验分4个处理,
In view of the rapid development of the plastic greenhouse in Beijing suburbs, it is very important to study the use of heating shed nursery in vegetable production to cultivate a large number of strong seedlings, shorten the seedling age, lower the cost, and improve the safety of existing seedling raising methods (Yangliu or improved Yangzai seedlings) Sex, etc., of great significance. This article describes the effect of warming seedlings of fruit and vegetables in a plunge in a plastic shed. The experiment was carried out in a small plastic shed (4.3 m wide and 30 m long) at Sijiqing Commune Grand Team Test Station. The heat source is a horizontal small boiler with a capacity of 50 kilograms, top and ground level, the outlet pipe is 2-inch iron pipe, 20 cm above the ground, the heat pipe is a 1-inch hard plastic pipe buried in the soil, backwater flows into the boiler, The whole device shown in Figure 1. Field trials divided into 4 treatment,
