摘　　要：高节竹是优良的笋材两用竹种,覆土栽培可以明显提高竹笋品质和经济效益。为科学实施高节竹林覆土栽培技术,分析了不同覆土厚度(ck和覆土10、30、50 cm)处理对高节竹笋产量、外观形态、营养物质、呈味物质、氨基酸含量等的影响。结果表明:覆土厚度对高节竹笋产量和品质有重要影响,覆土10 cm、30 cm、50 cm均可提高竹笋产量和品质。其中,覆土10 cm对高节竹笋产量和品质提高程度有限,覆土30 cm、50 cm会显著提升高节竹笋产量和品质,但两者间无显著差异,而且覆土50 cm明显增加投资成本,也不利于高节竹林的可持续经营。因此,从竹笋品质、经济效益等综合分析认为高节竹覆土高品质竹笋栽培的适宜覆土厚度为30 cm。Phyllostachys prominens is a superior bamboo species for both shoot and culm production.The quality and economic benefit of bamboo shoots could be significantly improved by soil-covering cultivation.In order to scientifically implement the soil-covering cultivation technique,the effects of different soil-covering thicknesses(CK,10 cm,30 cm and 50 cm)on the yield,appearance,nutrients,flavor substances,amino acid contents of Phyllostachys prominens shoots were analyzed.The results showed that the thickness of covering soil had important impacts on the yield and quality of bamboo shoots.Soil covering thicknesses of 10 cm,30 cm and 50 cm all led to the elevated yield and quality of bamboo shoots.While 10 cm soil covering had limited effects,both 30 cm and 50 cm coverings significantly improved the yield and quality of bamboo shoots,although there was no significant difference between these two treatments.And 50 cm soil covering apparently incurred higher cost,which was not conducive to the sustainable management of Phyllostachys prominens plantation.Therefore,from the comprehensive analysis of shoot quality and economic benefits,it was concluded that the suitable soil-covering thickness for the high-quality shoots cultivation of Phyllostachys prominens was 30 cm.
