摘要
以有机肥“黑珍珠”为研究对象,线辣椒为指示作物,研究有机肥对线辣椒的施用效果及其环境效应。结果表明,有机肥“黑珍珠”和农民习惯施肥比较起来,可以明显促进线辣椒的营养生长和生殖生长;硝态氮含量降低12.6mg/kg;维生素C含量提高了201mg/kg;粗脂肪含量提高了1.68%;可以增产10.8%,但和等养分量的NPK化肥比较起来,差别不明显。有机肥“黑珍珠”和等养分量的NPK化肥和农民习惯施肥比较起来,可以明显减少土体硝态氮淋失。
Applied effect and environment effect of organic fertilizer black pearl on capsicum were studied by using capsicum as indicating crop. The obtained result showed that compareed with farmer custom fertil- izer, organic fertilizer black pearl could promote vegetative growth and reproductive growth obviously. It could decrease Nitrate-N content by 12.6mg/kg and increase Vitamin C content by 201mg/kg, coarse fat by 1.68%. It also could increase yield by 10.8%. While organic fertilizer black pearl and NPK chemical fertilizer no difference. Organic fertilizer black pearl could decrease Nitrate-N leaching compare with NPK and custom fertilizer
