毛竹笋用林覆盖培育技术研究

Study of Covering Technology of Bamboo Forest

摘要:

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（0 cm）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 m2,较对照增产66.40%。

Abstract:

Abstracts: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 to 1 547.68 kg/667 m2, increasing 66.40% compared to the control group.
