Abstract

Seaweed foliar fertilizer is one species of foliar fertilizer made by different processing technics,used seaweed as extracting material.In this experiment,effects of 8 species of seaweed foliar fertilizers,for instance,mannite,amino acid,alginate,iodine,indole butyrate,gibberellin,Laminaria japonica slurry and Entermorpha prolifera slurry foliar fertilizers,on yield and quality of spinach(Spinacia oleracea L.) and pakchoi(Brassica campestris L.ssp.Chinensis Makino var.communis Tsen et Lee) were investigated at plastic shed and open-field growing.The results showed that 8 species of seaweed foliar fertilizers increased obviously the yields of spinach and pakchoi,generally increasing over 10%.Laminaria japonica slurry fertilizer increased most obviously the yield of spinach and pakchoi,and then mannite and gibberellin foliar fertilizers.Spraying seaweed foliar fertilizers could remarkably increase the contents of soluble sugar and Vc,decrease nitrate content and not change soluble protein content in spinach and pakchoi.

8 of 17 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
