培土栽培对麻竹笋品质的影响机理研究

为了评价不同栽培模式对麻竹笋品质影响,提高竹林经济效益,采用培土栽培和不培土栽培两种方式,通过研究麻竹笋外观形态、营养物质、呈味物质及氨基酸含量,分析了不同培土栽培对麻竹笋品质的影响。结果表明:(1)培土栽培的麻竹笋个体重量、基茎、长度及可食率较不培土栽培竹笋分别显著提高了28.09%、12.76%、19.61%、23.53%,箨壁厚度显著降低了46.43%。(2)培土栽培的麻竹笋灰分、蛋白质、脂肪及淀粉含量较不培土栽培竹笋分别显著下降了10.08%、12.77%、26.09%、48.84%,而还原糖、可溶性糖、水分及维生素C含量均不同程度增加。(3)培土栽培的麻竹笋单宁、草酸、纤维素、木质素含量较不培土栽培竹笋分别下降26.32%、20.26%、39.12%、25.47%。(4)培土栽培的麻竹笋氨基酸总量较不培土栽培竹笋显著增加了26.08%,其中的苦味、芳香类和鲜味氨基酸含量占比均下降,但甜味氨基酸占比则显著上升。研究发现,培土栽培可以改善麻竹笋外观形态,同时增加竹笋甜味、减少粗糙度和酸涩味,从而使竹笋品质得到明显提升。

Systems of Soilless Culture in China

Soilless culture in China has developed rapidly in recent years. The area of soilless culture in China was about 0.1 ha in 1985, 117 ha in 1995, but in 2002 the area reached to 865 ha. This paper introduced the brief history of soilless culture in China, and the main soilless culture systems. The present situation and problems are also discussed in this paper.
