The eucalyptus has beautiful trees, bright red leaves in the spring, yellow flowers in the summer and golden leaves in autumn. It is a good material for gardening because it gathers flowers, appreciates fruits and leaves. Now its cultivation management technology is introduced as follows, for reference only. Biological characteristics Eucalyptus tree height up to 16 meters, the crown was spherical, bark grayish brown, thin longitudinal cracks, branchlets slightly ribbed, lenticels. Oddly pinnate, sometimes partly lobed, deeply incomplete, two-pinnate, compound leaflets, leaflets 7 to 15, ovoid or ovate oblong, margin irregularly coarsely serrate, often near base Splinters. The terminal panicles, large and evacuated, small flowers, golden yellow. Capsule triangular-ovate, 5 cm to 7 cm long, ripe orange, flowering from June to July, fruit mature from September to October. The eucalyptus tree is hi light, it is also resistant to half yin, cold-resistant, drought-tolerant, hi moist environment, resistant to thin, hi born in calcareous soil, light saline-alkali, can be normal in mild saline-alkaline soil with pH 8.8 and salt content 0.2% It grows best in deep, fertile, and good-permeability sandy loam. Water and fertilizer management The banyan tree humid environment, in addition to planting to be poured into the water, after three, in the 5,6,9,10,11 months each should be poured one or two permeable, to keep the soil moist is appropriate, should be poured in early December Frozen water. In early March of the following year, it is necessary to return to Qingshui in a timely manner, to flood once in April, May, September, October, and November, and to provide abundant rainfall in July and August. If the weather is not too dry, then it is not necessary to water, and in early December, Should be poured antifreeze water. In the third year, watering is performed according to the second year method. From the fourth year onwards, it is sufficient to pour in enough water and frozen water in early spring and early winter. If the rest of the season is not too dry, it can be watered without relying on natural precipitation. After the heavy rain in the rainy season in summer, water should be promptly removed to prevent water from rot. The eucalyptus trees are hi-fat, in addition to the application of base fertilizers in addition to planting, they should also be topdressed during their growth period. In general, in the early winter of the year of planting, combined with pouring antifreeze water, some fermented beef horse dung or hemp sauce residue can be applied. After the flowering of the following year, some NPK fertilizers can also be applied, and once in the early winter, the farm manure can be applied again. The subsequent management can be carried out according to this method.
Vitamins:
Vitamin A:
Retinol. Carotene compounds responsible for transmitting light sensation in the
retina of the eye. Deficiency leads to night blindness.
Beta carotene: An
antioxidant which protects cells against oxidation damage that can lead to cancer.
Beta carotene is converted, as needed, to vitamin A. Food sources of beta
carotene include vegetables such as carrots, sweet potatoes, spinach and other
leafy green vegetables; and fruit such as cantaloupes and apricots. Excessive
carotene in the diet can temporarily yellow the skin, a condition called
carotenemia, commonly seen in infants fed largely mushed carrots.
Vitamin B1:
Thiamin, acts as a coenzyme in body metabolism. Deficiency leads to beriberi, a
disease of the heart and nervous system.
Vitamin B2:
Riboflavin, essential for the reactions of coenzymes. Deficiency causes
inflammation of the lining of the mouth and skin.
Vitamin B3:
Niacin, an essential part of coenzymes of body metabolism. Deficiency causes
inflammation of the skin, vagina, rectum and mouth, as well as mental slowing.
Vitamin B6:
Pyridoxine, a cofactor for enzymes. Deficiency leads to inflammation of the
skin and mouth, nausea, vomiting, dizziness , weakness and anemia.
Folate (folic
acid): Folic acid is an important factor in nucleic acid synthesis (the genetic
material). Folate deficiency leads to megaloblastic anemia.
Vitamin B12: An
essential factor in nucleic acid synthesis (the genetic material of all cells).
Deficiency leads to megaloblastic anemia, as can be seen in pernicious anemia.
Vitamin C:
Ascorbic acid, important in the synthesis of collagen, the framework protein
for tissues of the body. Deficiency leads to scurvy, characterized by fragile
capillaries, poor wound healing, and bone deformity in children.
Vitamin D: A
steroid vitamin which promotes absorption and metabolism of calcium and
phosphorus. Under normal conditions of sunlight exposure, no dietary
supplementation is necessary because sunlight promotes adequate vitamin D
synthesis in the skin. Deficiency can lead to osteomalacia in adults and bone
deformity (rickets) in children.
Vitamin E:
Deficiency can lead to anemia.
Vitamin K: An
essential factor in the formation of blood clotting factors. Deficiency can
lead to abnormal bleeding.
Nutritions:
For the treatment
of nutritional disease, any of the nutrient-related diseases and conditions
that cause illness in humans. They may include deficiencies or excesses in the
diet, obesity and eating disorders, and chronic diseases such as cardiovascular
disease, hypertension, cancer, and diabetes mellitus. Nutritional diseases also
include developmental abnormalities that can be prevented by diet, hereditary
metabolic disorders that respond to dietary treatment, the interaction of foods
and nutrients with drugs, food allergies and intolerances, and potential
hazards in the food supply. All of these categories are described in this
article. For a discussion of essential nutrients, dietary recommendations, and
human nutritional needs and concerns throughout the life cycle, see nutrition,
