根施硒肥对藤茶硒含量及产量的影响

Effect of Root Application of Selenium Fertilizer on Selenium Content and Yield of Ampelopsis Grossedentata

为藤茶富硒增产栽培技术的研究提供理论依据,以藤茶(Ampelopsis grossedentata)为试验材料,研究了富硒生物有机肥施用量对藤茶嫩茎叶硒含量及产量的影响.结果表明,在0~200kg/667m^2范围内,随着富硒生物有机肥施用量的增加,藤茶嫩茎叶硒含量及产量均呈上升趋势,富硒生物有机肥施用量在200kg/667m^2时,硒含量为4.54mg/kg,产量为74.52kg/667m^2.本研究对藤茶产业的发展具有推进作用.

In order to provide theoretical basis for the study on Se-enriched and yield increasing cultivation techniques of Ampelopsis grossedentata, the effects of application amount of Se-enriched bio-organic fertilizer on selenium content and yield of A.grossedentata were studied with A.grossedentata as experimental material.The results showed that in the range of 0 to 200 kg/667m^2,with the increase of Se-enriched bio-organic fertilizer,the selenium content and yield of A.grossedentata showed an upward trend,and when Se-enriched bio-organic fertilizer application amount was 200 kg/667m^2,the selenium content was 4.54 mg/kg,and the yield was 74.52 kg/667m^2.This study will promote the development of A.grossedentata industry.
