试验方法:将含硒煤矸石经粉碎、活化后按一定剂量直接施入农田或作为饲料添加剂,生产富硒农产品和富硒禽蛋。结果:按每亩100 kg施入稻田和茶园,大米硒含量由0.086 mg/kg增加到0.38 mg/kg,增硒4.4倍;茶叶含硒量在两个月内由0.11~0.21 mg/kg增加到0.34~0.82 mg/kg;番茄含硒量均值由对照组的0.032 mg/kg增加到0.46 mg/kg;鸡、鸭蛋硒含量在1周之内增加5倍。试验证明,恩施丰富的含硒煤矸石经加工后作为肥料和饲料添加剂,用于生产富硒农产品和畜、禽产品,能使农作物补硒丰产,增加附加值。
Test Method: The selenium-containing coal gangue was crushed, activated by a certain dose directly into the farmland or as a feed additive to produce selenium-enriched agricultural products and selenium-rich eggs. Results: The content of selenium in rice increased from 0.086 mg / kg to 0.38 mg / kg and 4.4 times to selenium by applying 100 kg per mu to paddy field and tea plantation. Selenium content in tea increased from 0.11 ~ 0.21 mg / kg in two months To 0.34 ~ 0.82 mg / kg. The average content of selenium in tomato increased from 0.032 mg / kg to 0.46 mg / kg in control group. Selenium content in chicken and duck eggs increased 5 times in 1 week. Experiments show that Enshi rich selenium gangue after processing as a fertilizer and feed additives for the production of selenium-rich agricultural products and livestock, poultry products, crops can make selenium yield and increase added value.
