Problems solved by technology

[0003] At present, most of the fertilizers used for planting mustard are poultry and livestock manure. In the traditional mustard planting, chemical fertilizers and pesticides are generally used, resulting in mustard with pesticide residues and poor flavor; on the other hand, organic fertilizers from poultry and livestock are often used. Poor air permeability leads to problems such as poor quality, incomplete nutrition, bad taste and low yield of mustard
