不同经营模式对毛竹叶片特性和竹笋产量的影响

Effect of Different Management Patterns on Leaf Characteristics and Shoot Yield of Phyllostachys heterocycla ‘Pubescens’

  • 摘要: 为了研究不同经营模式对毛竹Phyllostachys heterocycla ‘Pubescens’笋用林叶片特征以及竹笋产量的影响,以不同经营模式(带状、层状、加客土和常规经营)的毛竹笋用林为研究对象,对毛竹叶片SPAD 值(soil and plantanalyzer development value,SPAD value)和叶面积指数(Leaf Aea Index,LAI)进行监测,并于次年春统计春笋产量。结果表明:不同经营模式下的毛竹叶片SPAD 值随时间呈现先升高后下降的变化趋势,而LAI 变化不明显;机械化带状经营模式中处理D3(条带宽度1 m,保留条带内立竹和适当竹鞭)的SPAD 值及LAI 均高于常规经营,且其LAI 显著高于(P<0.05)层状和加客土经营中的各处理。层状经营模式中处理C2(去除竹林地0 ~ 25 cm 土层的竹鞭)的SPAD 值和LAI 均较低于同时期的其他处理;机械化经营模式中的处理D3 和处理T6(加客土6 cm)的春笋产量最高;毛竹SPAD 值、LAI 及春笋产量三者均呈极显著正相关(P<0.01),其中SPAD 值与春笋产量呈极显著正相关(P<0.01)。

     

    Abstract: To investigate the effects of different management patterns on leaf characteristics and shoot yield of shoot-use Phyllostachys heterocycla ‘Pubescens’ forest, soil and plant analyzer development value (SPAD) ,leaf area index (LAI) , and bamboo shoots yield in the next spring were investigated and analyzed under four management patterns (clear cutting band, layer transformation, adding transported soil,conventional management) The results showed that SPAD values increased at first and then decreased,LAI did not change significantly. The SPAD value and LAI of D3 (1 m strip, clear some bamboo rhizome of standing bamboo)treated in mechanized strip management model were higher than artificial management, and LAI was significantly higher than mechanized layering and adding guest soil management. The SPAD value and LAI of C2 (clear bamboo rhizome of 0~25 cm soil depth )treated in the layered management model are lower than other treatments in the same period. The processing of D3 treated and T6 (guest soil is 6 cm)treated in the mechanized management mode is the highest. it had evident positive relation of SPAD value, LAI and shoot yield under different treatment.
