摘要
研究不同覆盖培育方法对毛竹林土壤温度变化、出笋规律和竹笋产量的影响,对于提高毛竹冬、春笋产量具有重要意义。以稻草和谷壳为覆盖物,通过设置不同覆盖厚度进行了研究。结果表明:覆盖林地各土层显著高于未覆盖林地的土壤温度,各覆盖处理地表(0cm)及地下(20 cm)处土壤最高温度分别在16.0~22.5℃和16.0~20.5℃之间;不同处理可使笋期提前42~65 d;林地覆盖后竹笋产量大幅增加,其中以稻草20 cm+谷壳20 cm的覆盖效果较佳,平均产量达1 547.68 kg/667 m^2,较对照增产66.40%。
The effects of different covering methods on soil temperature of bamboo forest,growth characterization and yield of bamboo shoots were studied.The results showed that：the soil temperature with different covering methods was obviously higher than the control group;the temperature of earth surface and underground 20 cm were 16.0~22.5 ℃、16.0~20.5 ℃,respectively;the bamboo shoots sprout was 42~65 d in advance by covering;the yield of bamboo shoots was increased largely,and the optimum was 20 cm of straw and 20 cm of rice chaff,which the average yield reached to1 547.68 kg/667 m^2,increasing 66.40% compared to the control group.
