一、电热线温床育苗的优点1.土温自控,不受外温变化影响,能为种子发芽和幼苗生长创造最佳地温条件,可使幼苗生长快、整齐度高、病害少。2.设备简单,占地少,可直接在温室或大棚地面铺线,做畦播种。用完可随时拆除,适宜大面积生产育苗。3.耗电量少,育苗成本低。每平方米苗床每天约耗电0.7度,原苗期20天,总用电量14度,电费支出0.98元,较煤火加温育苗每平方米节省0.72元。
First, hot-wire electric hotbed nursery advantages 1. Soil temperature control, not subject to changes in external temperature, for seed germination and seedling growth to create the best temperature conditions, seedlings can grow fast, high uniformity, less disease. 2. Simple equipment, small footprint, can be directly in the greenhouses or shed floor line, do 畦 sowing. Used up can be removed at any time, suitable for large-scale production of nursery. 3. Less power consumption, nursery low cost. Seedbed per square meter per day about power 0.7 degrees, 20 days of the original seedling stage, the total electricity consumption of 14 degrees, electricity costs 0.98 yuan, compared with coal fire nursery save 0.72 yuan per square meter.
