麻竹林下环境因子对仿野生长裙竹荪产量影响研究

对比分析了麻竹林下仿野生条件栽培的"兴农"和"京平"2个品系的4个长裙竹荪品种的产量。结果显示:兴农D₈₉与京平D₈₉、兴农D₁与京平D₁产量无显著性差异,兴农D₈₉、京平D₈₉产量显著高于兴农D₁、京平D₁;温度、湿度、光照等相关环境因子对产量有一定的影响,麻竹林分郁闭度为0.7时的竹荪产量高于郁闭度为0.9和0.5时的产量,表明光照过强或光照不足均抑制竹荪产量;竹荪生长的林内最适生长温度为23~29℃,低于22℃或超过30℃时竹荪产量均显著下降;竹荪生长的林内最适湿度为65%~80%,湿度过高或过低均抑制竹荪产量。

Effect of Environmental Factors in Understory Dendrocalamus latiflorus on the Yield of Imitative Wild Cultured Bamboo Fungus

This paper analyzed the yield of 4 varieties of bamboo fungus under the brands of XingNong and JingPing, which were imitated wild cultured under Dendrocalamus latiflorus. The results indicated that there is no significant difference between XingNong D₈₉ and JingPing D₈₉, and between XingNong D₁ and JingPing D₁, while the yield of XingNong D₈₉ and JingPing D₈₉is significantly higher than that of XingNong D₁. The temperature, humidity, light and relevant environmental factors have certain impacts on the yield, and the canopy density of D. latiflorus is 0.7, the yield of bamboo fungus is higher than those with the canopy density at 0.9 and 0.5, which showed that strong light and weak light inhibit the yield of bamboo fungus. The optimum temperature is 23℃ to 29℃ for the growth of bamboo fungus, while the yield of bamboo fungus show a significant reduction when the temperature is lower than 22℃ or above 30℃. The optimum humidity for the bamboo fungus growth is 65%~80% at the understory D. latiflorus, and higher or lower humidity has a negative effect on its yield.
