每年12月至次年元月是北方一年中最寒冷的季节,气温常在O℃左右,最低在-10℃以下。这样的外界气温不利于香菇子实体生长,是鲜香菇上市的淡季。 日光温室是一种高投入、高技术、高产出、高效益的农业设施,具有良好的采光性和增温保温性,近几年在蔬菜生产上得到广泛应用。利用日光温室栽培香菇,在严寒的冬季室温仍能保持8℃以上,高于子实体生育的最低温度,可以克服北方冬季气温低不利香菇子实体生长的问题,使鲜香菇在双节期间照常上市,因此在河南、河北、山东、北京、天津、辽宁等省市发展较快。笔者于1997年对河南扶沟、博爱,河北遵化,天津蓟县,北京郊县等利用日光温室栽培的菇场进行了考察,现报告如下:
From December to January of the next year, the coldest season in the northern part of the year, the temperature is usually around 0 ° C and the lowest is below -10 ° C. This outside temperature is not conducive to the growth of mushroom fruiting bodies, is the off-season listing of fresh mushrooms. Solar greenhouse is a high input, high technology, high output, high efficiency agricultural facilities, with good lighting and temperature insulation, in recent years in the production of vegetables has been widely used. The use of solar greenhouse cultivation of mushrooms, in the frosty winter room temperature can still be maintained above 8 ℃, higher than the fruiting body of the lowest temperature, can overcome the northern winter low temperature disadvantage mushrooms fruiting body growth problems, so that fresh mushrooms in the double section as usual market , So in Henan, Hebei, Shandong, Beijing, Tianjin, Liaoning and other provinces and cities developed rapidly. In 1997, the author investigated the mushroom farm cultivated by solar greenhouse in Fugou, Frangipani, Zunhua, Tianjin Jixian and Beijing suburbs. The report is as follows:
