蓝莓种植土壤肥力检测及改良研究

蓝莓作为一种新兴果树，因具有较高的营养与药用价值，倍受广大消费者的青睐，但其生长发育对土壤环境的要求比较严格，严重的影响了该产业的可持续发展。为了加速蓝莓的高产优质栽培，本研究以测定其种植土壤性状为基础，通过施用蓝莓专用肥、磷酸及草木灰进行土壤改良。结果证明：蓝莓种植基地土壤与改良前相比，改良后的土壤N(200.5~1145.5 mg/kg)、K(10.45~63.5 mg/kg)含量均提高，但P(120.2~626.3 mg/kg)含量相差不大，有机质差异不显著；经t检验统计，pH差异显著，pH 4.15~4.8最适宜蓝莓生长。总之，改良土壤适合蓝莓的区域化种植，研究结果为其大规模推广提供了必需的参考。

Soil Fertility Detection and Improvement of Blueberry Planting

As a newly-developing fruit tree, blueberry has high nutrition and medicinal value, and is highly favored by consumers. However, its growth and development have strict requirement on soil environment, which seriously affects the sustainable development of blueberry industry. In order to accelerate the high yield and good quality cultivation of blueberry, soil improvement tests were carried out by applying blueberry special fertilizer, phosphoric acid and plant ash based on the determination of blueberry cultivation soil properties. The results showed that the content of N and K of the improved soil increased to 200.5 to 1145.5 mg/kg and 10.45 to 63.5 mg/kg respectively than before, but the content of P (120.2~626.3 mg/kg) had little difference, and the organic matter content had no significant difference. The t test showed that the pH values were significantly different and pH 4.15 to 4.8 was the most suitable range for blueberry cultivation. In a word, the improved soil was suitable for regional planting of blueberry, and this study could provide certain reference for its large-scale promotion.
