根施硒肥对核桃硒含量的影响

Effect of Root Application of Selenium Fertilizer on Selenium Content of Walnut

[目的]研究富硒核桃生产技术。[方法]以香玲核桃树为材料,选用苏州硒谷科技有限公司提供的基准富硒肥料,研究核桃根施不同用量外源硒肥核桃仁的硒含量。[结果]根施硒肥0.5~2.0 kg/株,随着硒肥用量的增加,核桃仁的含硒量呈上升趋势,根施硒肥2.0 kg/株的核桃树,核桃仁的含硒量明显增大。[结论]研究结果可为示范推广种植富硒核桃提供了技术支撑。

[Objective]The aim was to study the production technology of selenium-enriched walnut.[Method]Taking Xiangling walnut tree as material,the selenium content of walnut kernel with different amounts of exogenous selenium fertilizer was studied by using the reference selenium-rich fertilizer provided by Suzhou Xigu Technology Co.,Ltd.[Result]The selenium content of walnut kernel increased with the increase of selenium fertilizer dosage when selenium fertilizer was 0.5-2.0 kg/plant.The selenium content of walnut kernel increased significantly when selenium fertilizer was 2.0 kg/plant.[Conclusion]This study provided technical support for demonstration and promotion of planting selenium-enriched walnut.
