河北省冷棚大球盖菇起始种植时间区划研究

Plastic greenhouses cultivated time zoning research of Stropharia rugosoannulata in Hebei Province

为探索河北省冷棚大球盖菇最佳起始种植时间,分析连续3年的冷棚内外气温数据得出大球盖菇起始种植气温指标,利用河北省近30年气温资料绘制适宜种植起始日期区划图,利用气温倾向率和Morlet小波分析进行波动性和周期分析。结果表明,河北省冷棚大球盖菇起始种植气温指标为棚外最高气温降至27℃以下;1991—2020年河北省冷棚大球盖菇起始种植时间日序257~274,平均265,逐年呈显著的推迟趋势(P<0.01),倾向率1.01d/10年;河北省冷棚大球盖菇起始种植时间整体从北到南、自西向东逐渐推迟。张家口市张北县开始最早,日序222,可于8月10日开始种植,邯郸市南部开始最晚,日序277,10月3日才可开始种植;冷棚大球盖菇起始种植时间存在明显的周期变化,表现为平缓-剧烈-平缓,10年左右的周期振荡最强,为第1主周期,第2主周期为4年。开展冷棚大球盖菇种植时间研究,可为精准种植提供科学依据。

In order to explore the best time for starting cultivation of Stropharia rugosoannulata in Hebei Province,temperature index for starting cultivation time was obtained by analyzing temperature data both inside and outside plastic greenhouses for three consecutive years,and isogram of suitable starting cultivation date was drawn by using temperature data of Hebei Province in the last 30 years.Trend and periodicity of starting cultivation date were analyzed by temperature tendency rate and Morlet wavelet analysis.Res-ults showed that temperature index for starting cultivation date in plastic greenhouses of Stropharia rugosoannulata in Hebei Province was the maximum temperature outside plastic greenhouse was lower than 27℃.From 1991 to 2020,day sequences of starting cultivation date of Stropharia rugosoannulata in plastic greenhouses in Hebei Province ranged from 257 to 274,average date was 265.There was a significant delay trend year by year(P<0.01),with a tendency rate of 1.01 d/10a.Starting cultivation date of plastic greenhouses Stropharia rugosoannulata in Hebei Province generally was gradually delayed from the north to the south and from the west to the east.The southern part of Handan City started the latest,with a day sequence of 277 on October 3rd,while Zhangbei County in Zhangjiakou City started the earliest,with a day sequence of 222 on August 10th.There were significant periodic variations in starting cultivation date,which showed a gentle-drastic-gentle pattern.The strongest periodic oscillation occurs around 10 years,with the first main cycle and the second main cycle lasting 4 years.Conducting research on cultivated time of Stropharia rugosoannulata could provide scientific basis for precise cultivation.
