[目的] 探索秸秆覆盖种植大球盖菇模式对经济林(尤其是刚刚荒改坡的经济林)清水产流和改土控草的影响,为坡地水源涵养、生态保育、控草保肥提供技术支撑。[方法] 在派河上游苦驴河的源头,选取2组不同种类的坡地经济林,利用秸秆覆盖种植大球盖菇技术,在大球盖菇生长的不同时期对该区域坡地水质、土壤有机质和杂草多样性进行分析。[结果] 采用秸秆覆盖种植大球盖菇的技术,平均能有效降低该地区水中总氮42.68%~50.47%,总磷45.72%~46.74%和悬浮物(SS)33.41%~36.58%的含量,同时增加土壤有机质的含量,平均增长了10.17%~16.42%,减少该区域杂草多样性和种类,有效降低了该地水肥流失,可在较短时间内无害且快速地增加该区域清水产流能力。[结论] 采用秸秆覆盖种植大球盖菇的技术,能有效降低坡地径流水中总氮、总磷和SS的含量,同时增加土壤有机质的含量,减少该区域杂草多样性和种类,起到控制水肥和水土流失作用,在当年荒改坡的坡地上,该作用更加明显。
[Objective] The influence of cultivating Stropharia rugosoannulata with straw on clean water runoff
soil improvement and grass control in economic forests(especially in the newly economic forest) was explored
in order to provide technical support in water conservation capacity
ecosystem conservation
grass control and soil fertility improvement.[Methods] Two different kinds of slope land economic forests in the source area of Kulü River at upstream of Paihe River was selected
the technology of straw mulching was used to plant Stropharia rugosoannulata
and the water quality
soil organic matter and weed diversity of the slope land were analyzed in different growth periods of the mushroom.[Results] The cultivation of Stropharia rugosoannulata with straw effectively reduced the content of total nitrogen (42.68%~50.47%)
total phosphorus (45.72%~46.74%) and suspended solids (SS
33.41%~36.58%) in the water in this area. At the same time
it increased the content of soil organic matter by 10.17%~16.42% on average
and reduced the diversity and species of weeds in this area
thus
effectively reduced the water and fertilizer loss
and increased clean water runoff in a short period.[Conclusion] Cultivating Stropharia rugosoannulata with straw can effectively reduce the contents of total nitrogen
total phosphorus and SS in the runoff
increase the content of soil organic matter
reduce the diversity and species of weeds in this area
and play an important role in controlling water
fertilizer and soil erosion. In addition
the effect may be even more pronounced in the newly economic forest changed by uncultivated land.
