为了研究复合肥中添加不同类型和不同含量腐殖酸的肥效,在15-5-10复合肥中添加腐殖酸原粉和不同质量分数的腐殖酸下脚料,以上海青、苦苣和小麦为试验对象,分别开展了盆栽和田间小区试验。结果表明:添加质量分数30%的腐殖酸下脚料的处理对上海青地上部鲜质量和叶绿素含量有促进作用;添加质量分数32%的腐殖酸下脚料的处理对苦苣地上部和地下部鲜质量、叶绿素含量有促进作用;添加不同类型腐殖酸的处理对提高小麦产量的作用不明显。在15-5-10复合肥中添加腐殖酸下脚料的效果优于添加腐殖酸原粉的,添加质量分数以30%~35%为宜。
In order to study the fertilizer effect of adding different types and different contents of humic acid in compound fertilizer, humic acid raw powder and different mass fractions of humic acid leftovers are added into 15-5-10 compound fertilizer, and taking Brassica chinensis L., Sonchus oleraceus L. and wheat as test subjects, potted and field plot experiments are carried out respectively. The results show that the treatment of adding 30% mass fraction of humic acid leftovers can promote the fresh weight and chlorophyll content of the overground parts of Brassica chinensis L.; the treatment of adding 32% mass fraction of humic acid leftovers can promote the fresh weight and chlorophyll content of Sonchus oleraceus L. above and below ground; the wheat yield increase effect of the treatment adding different types of humic acid is not obvious. The effect of adding humic acid leftovers to 15-5-10 compound fertilizer is better than adding humic acid raw powder, and the appropriate mass fraction is 30%-35%.
