【摘要】 通过向栽培基质中添加不同浓度生物有机硒肥栽培黑木耳。结果表明，当干料中硒含量为1 mg·kg^-1～5 mg·kg^-1时，可以促进黑木耳菌丝生长、加快菌丝生长速度、降低污染率；可有效提高子实体产量及转化率；且子实体中硒含量与干料中硒含量呈正相关，粗蛋白和总糖含量与干料中硒含量呈正相关，粗纤维和灰分含量与干料中硒含量呈负相关。配方4 (干料中硒含量为4 mg·kg^-1)菌丝生长速度最快、长势浓密且污染率低，子实体产量和转化率最高，商品性状优良，子实体硒含量达到富硒标准，经济效益最好。更多还原

【Abstract】 Auricularia heimuer was cultivated by adding different concentrations of biological organic selenium frtilizer. The results showed that when the selenium content of dry substrate is 1 mg·kg^-1-5 mg·kg^-1 can promote the mycelial growth of A.heimuer, accelerate the mycelial growth rate and reduce the pollution rate; the yield of fruit body and converted efficiency were improved; the selenium content of fruit body was positively correlated with that of dry substrate, there was a positive correlation between crude protein and total sugar and the selenium content of dry substrate, crude fiber and ash were negatively correlated with he selenium content of dry substrate. Formula 4(the selenium content of dry substrate is 4 mg·kg^-1) had the fastest mycelial growth rate and dense growth, pollution rate is low, fruit body yield and converted efficiency were the highest, commodity properties is good, the selenium content of fruit body reached the standard of selenium enrichment, economic benefit is the best.更多还原
