The main symptoms of plant deficiencies
Nitrogen deficiency: Light green plants, old yellow leaves at the base, brown when dry
Stems short and fine, with few branches or tillers, with premature aging
If nitrogen deficiency occurs in fruit trees, it is characterized by small fruit, few fruit, and hard skin.
Phosphorus deficient: dark green plants, often red or purple, dark green when dry
The stems are short and fine, the base leaves turn yellow, the flowering period is delayed, the seeds are small, and they are not full
Potassium deficiency: The stems are easy to fall, the edges of the leaves are yellow, scorch, and broken, and necrotic spots appear between the veins. The entire leaf is sometimes curled or shrunken.
Grain crops and other sugar-rich crops require large quantities of potassium at later growth stages, such as cereals and potatoes, sweet potatoes, watermelons, grapes, etc.
Magnesium deficiency: leaves turn yellow, sometimes variegated (and the difference in nitrogen deficiency), veins are still green, and veins turn yellow, sometimes purple, appear necrotic spots
Iron deficiency: pulsating between veins, showing a clear reticular pattern. When severe, the entire leaf, especially the young leaves, is pale yellow or even white.
Such as tea, gardenia, etc. easy to show this symptom
Boron deficiency: first appear at the top, if the top stops growing
Deformity and shrinkage of young leaves
Irregular retreat between veins
Rapeseed flowers are not real, cotton buds without flowers, apples, fruit rot, radish heart rot, etc. are the reasons for the lack of boron
Zinc deficiency: small clusters of leaves, spots on both sides of leaves, short plants, shortened internodes, delayed growth period
If the tree's lobular disease, maize white flowers, etc.
Copper deficiency: neonatal leaves are chlorotic, and the tip of the leaf is white curly and papery. The leaves show necrotic spots and then wither.
[Composition]
The main component of this preparation is human immunoglobulin, which is prepared by cold ethanol fractionation of human plasma from healthy donors. The manufacturing process contains a step to remove anticomplementary activity and a dual viral inactivation process. It contains a suitable amount of glucose or maltose as stabilizer (see table below), but does not contain any antiseptic or antibiotic. The distribution of IgG subclasses is close to the serum level of normal subjects and maintains the bioactivity of Fc fragment of IgG.
[Indications]
1. Primary
agammaglobulinemia, such as X-linked hypogammaglobulinemia,
common variant immunodeficiency diseases, immunoglobulin G subclass deficiency,
etc.
2. Secondary
immunoglobulin deficiency diseases, such as severe infection, septicemia of
newborn, etc
