摘要

为给湘南地区千年桐林药间作提供技术支撑,在湘南地区选择已进入盛果期的4年生千年桐,分别设置千年桐+草珊瑚(Ⅰ)、千年桐+玉竹(Ⅱ)、千年桐+山豆根(Ⅲ)、千年桐+金银花(Ⅳ)、千年桐+菊花(Ⅴ)、千年桐纯林(Ⅵ,作为对照)这6种种植模式进行了林药间作试验,观测了不同间作模式下千年桐的产果量、药材产值、林地土壤水文效益和土壤冲刷量,分析了不同间作模式的综合效益。研究结果表明:1)模式Ⅱ和Ⅳ的千年桐单株产果量最高,分别为7.17、7.13 kg,其与对照间的差异均显著;2)模式Ⅳ的药材产值最高,每hm2可达10.8万元;3)模式Ⅰ、Ⅲ、Ⅴ的土壤涵养水源能力最强,分别为1 799.7、1 776.4、1 817.2 t·hm~(-2),且与对照间的差异均显著;4)模式Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ的土壤冲刷量分别为299.3、329.2、396.7、423.7、410.3 t·km~(-2),都显著低于模式Ⅵ(对照,504.5 t·km~(-2));5)模式Ⅳ的综合效益最高,而模式Ⅰ、Ⅱ、Ⅲ、Ⅴ的综合效益依次次之,综合效益最差的为模式Ⅵ(对照)。
        In order to provide some technical supports for Aleurites montana forest-medicinal plant intercropping in southern Hunan, choosing 4-year-old A. montana at full bearing period in southern Hunan as research objects, six planting patterns were set, including A. montana + Sarcandra glabra( Ⅰ), A. montana + Polygonatum odoratum( Ⅱ),A. montana + Euchresta japonica( Ⅲ), A. montana + Lonicera japonica( Ⅳ), A. montana + Dendranthema morifolium( Ⅴ) and A. montana spure stand( Ⅵ, CK), A. montana fruit yield, output value of medicinal materials, soil hydrological benefits and soil erosion were observed under different intercropping patterns, and comprehensive benefits of different intercropping patterns were analyzed. The results showed that, in pattern Ⅱ and pattern Ⅳ, A. montana had the highest fruit yield per plant, which were 7.17 and 7.13 kg and were significantly different from CK. Inpattern Ⅳ, output value of medicinal materials was the highest and up to 108 000 Yuan per hm2. In pattern I, pattern Ⅲ and pattern Ⅴ, soil water conservation capacities were the strongest, which were 1 799.7, 1 776.4 and 1 817.2 t·hm~(-2), andwere significantly different from CK. In pattern Ⅰ, pattern Ⅱ, pattern Ⅲ, pattern Ⅳ and pattern Ⅴ, soil erosionamountwere 299.3,329.2, 396.7, 423.7, 410.3 t·km~(-2), respectively, which were significantly lower than pattern Ⅵ(CK, 504.5 t·km~(-2)).Comprehensive benefit of pattern Ⅳ was the highest, benefits of pattern Ⅰ, pattern Ⅱ, pattern Ⅲ and pattern Ⅴ were were reduced in turn, and the worst was pattern Ⅵ(CK).
