不同有机基肥对辽宁地区黄精生长的影响

Effects of Different Organic Base Fertilizers on the Growth of Polygonatum sibiricum in Liaoning Areas

分别以海藻菌豆生物有机肥、发酵鸡粪、发酵牛粪作为基肥,研究不同有机基肥对黄精生长的影响。试验结果表明,海藻菌豆生物有机肥施肥量为1.5 kg/m^(2)、3.0 kg/m^(2)时,黄精当年出苗率均达到96.67%;施肥量为4.5 kg/m^(2)时,黄精当年出苗率达到93.33%,地上茎高达34.34 cm,茎粗达3.05 mm,叶片轮数9.0。牛粪施肥量为3.0 kg/m^(2)时,黄精地上茎高达到23.3 cm,茎粗达3.35 mm,叶片轮数8.3。综合比较,以海藻菌豆生物有机肥作基肥,特别是4.5 kg/m^(2)施用量更有利于黄精地上部分的生长;从控本增效考量,以牛粪3.0 kg/m^(2)的标准施用基肥,较施用海藻菌豆生物有机肥更具性价比。

The effects of different organic base fertilizers on the growth of Polygonatum sibiricum were studied by using seaweed fungus bean bio-organic fertilizer,fermented chicken manure and fermented cattle manure as base fertilizers.The results showed that the emergence rate of Polygonatum sibiricum reached 96.67%when the application amount of seaweed fungus bean bio-organic fertilizer was 1.5 kg/m^(2)and 3.0 kg/m^(2).When the fertilizer application amount was 4.5 kg/m^(2),the emergence rate of Polygonatum sibiricum reached 93.33%,the stem height was 34.34 cm,the stem diameter was 3.05 mm,and the number of leaf rounds was 9.0.When the amount of cattle manure was 3.0 kg/m^(2),the stem height of Polygonatum sibiricum was 23.3 cm,the stem diameter was 3.35 mm,and the number of leaf rounds was 8.3.By making a comprehensive comparison,taking seaweed fungus bean bio-organic fertilizer as base fertilizer is more conducive to the growth of the aboveground part of Polygonati sibiricum especially when the fertilizer application amount was 4.5 kg/m^(2);considering cost control and efficiency enhancement,when the application amount of base fertilizer with cattle dung is 3.0 kg/m,which is more cost-effective than the application of seaweed fungus bean bio-organic fertilizer.
