摘要:

为研究微量元素硒对板栗籽实养分含量变化的影响,提升板栗的营养价值,筛选出高效的硒肥施用技术培育富硒板栗。用含硒量138 mg/kg的生物有机肥,按施肥量设置0.0(CK)、1.5、2.5、3.5、4.5 kg/株5个处理,根施板栗结果树,对林分土壤、叶片、板栗籽实硒含量及栗实主要成分进行检测,研究硒含量变化及栗实硒与其它养分含量的相关性。结果表明:土壤、叶片中的硒含量随硒肥用量的增大和年份的积累呈递增趋势;硒元素能以代谢的方式进入到栗实中,并随着土壤、叶片中硒的积累,促进硒向栗实的转移;板栗籽实硒含量显著高于对照,同时硒的摄入也促进了栗实对其它营养成分的吸收。试验第四年,处理3栗实含硒量最高,达到0.539 mg/kg,可溶性糖、蛋白质、淀粉含量分别达到了9.673、4.817、 40.707 g/100g,均显著高于其它处理。由此可见,正确使用含硒生物有机肥,全面改善了板栗品质,提高了板栗附加值,同时食用健康的富硒产品,也将为人们提供一种健康的补硒方式。

Abstract:

The paper aims to study the impact of selenium on the nutrient content of chestnut seed, improve chestnut nutritional value, and find out an efficient way of selenium fertilizer application to cultivating selenium-enriched chestnut. The bio-organic fertilizer with selenium content of 138 mg/kg was used in the study. Five treatment groups were set according to the amount of fertilizer of 0.0(CK), 1.5, 2.5, 3.5 and 4.5 kg per tree. For all sample chestnut trees with fruits, we detected the selenium content in soil, leaves and chestnut seeds and analyzed the main components of chestnut to study the correlation between the selenium content in fertilizer and the content of selenium and other nutrients in chestnut. The results showed that the selenium content in soil and leaves increased with the increase of selenium fertilizer level and planting years. Selenium could enter chestnut through metabolism, and promote the transfer of selenium to chestnut with the accumulation of selenium in soil and leaves. The selenium content of chestnut under selenium fertilizer application was significantly higher than that of the control group, and the uptake of selenium also promoted the absorption of other nutrients. In the fourth year, the content of selenium in chestnut under treatment 3 was the highest, reaching 0.539 mg/kg, and the content of soluble sugar, protein and starch was 9.673, 4.817 and 40.707 g/100g, respectively, which were significantly higher than those of the other treatments. In conclusion, the proper use of fertilizer with selenium can improve the quality and additional value of chestnut, which will be a healthy way to supplement selenium for human being.
