The main NPK fertilizer production machines

Horizontal mixer

When SEEC horizontal mixer is working during the NPK compound fertilizer production line, the NPK material in the machine is operated by two opposing rotors, and the compound motion is carried out. The horizontal mixer slurry drives the material to rotate counter clockwise along the inner wall of the machine groove. On the one hand, it drives the material to turn around, forming a weightless zone outside the overlap of the two rotors. In this area, no matter the shape, size and density of the material, the NPK material can be floating in an instantaneous weightlessness state. This makes the material in the machine groove form an omni-directional continuous loop, alternating shear, so as to achieve fast and soft mixing uniform effect.

Are there any effects on NPK fertilizer on coriander seed and yield production?

Nitrogen fertilizer can be used to judge the nitrogen supply from leaf area and leaf color. In the seedling stage, the general plant nitrogen deficiency is manifested as slow growth, stunted plants, thin and small leaves, green and yellow leaves. Nitrogen fertilizer has obvious effect on promoting plant growth and health. And potassium fertilizer can enhance the tolerance of plants to various adverse conditions, such as drought, low temperature, salt content, disease and insect damage, lodging, etc.

Phosphorus can promote the formation and growth of early root system. Improving the ability of plants to adapt the external environmental conditions, and help plants withstand the cold winter.

If the crops are short of phosphorus, it will lead to plant dark green, and sometimes are red or purple, dark green when dry. In addition, it also will lead to the characters of stem short and thin, leaf base yellow, flower lately, seeds small.

Lack of potassium: the old leaves turn yellow along the leaf edge, and the leaf edges appear to be burning when severe.

So if the coriander seed has these phenomenon, it’s necessary to use NPK fertilizer. and starting an NPK fertilizer production line will bring in a tidy profit for you.
