Carnation flowers are beautiful in shape, attractive in color, scented and varied in variety, and have a long period of flowering and are favored by people. They are important cut flowers of all countries in the world today; they are also the most widely used flower materials in ceremonial flowers - Elegant flowers such as flower arrangements, bouquets, flower baskets, bouquets, corsages and garlands are all inseparable from it; it can also be cultivated in an open field, arranged in flower beds, or potted for indoor decoration. Specific cultivation techniques are as follows.
(1) The establishment of female nurseries and scion nurses For a long time, the vast majority of flower growers rely on self-breeding and self-cultivation, and the method of breeding from the selected lateral buds of the mother plant of the picking field has been adopted. The seedlings are reused for multiple generations. The quality of seedlings declined. The quality of their seedlings will directly affect the growth potential of field plants after planting and the future yield and quality of flowers. Therefore, the nursery and the scion nursery shall be established when cultivated. The techniques are as follows.
1 Seedling preparation Carnation is a plant of fibrous roots, requiring loose, air-permeable, water-retaining and fertility-preserving soil conditions; seedbed soil is preferably made of peat or any other medium that is dominated by peat; sufficient fertilizer is applied to the medium. Including nitrogen, phosphorus, potassium and some trace elements; pour a lot of water 3 days before planting to make the soil fully wet; the thickness of the medium is at least 20 cm to ensure that the carnation mother has sufficient soil roots to absorb nutrients and normal growth and development; Saplings or sorghum should be established according to the specifications of the greenhouse or greenhouse; the seedbed height should be 80 -10 . The centimeter is suitable, and the depth of the seedbed is preferably 25-30 centimeters, and not less than 20 centimeters.
2 Introduce the female parent according to the market requirements and the local cultivated eco-environment to select the varieties, introduce the fine varieties with high yield, excellent quality, strong growth, strong disease resistance and good stress resistance, carefully nurture according to the characteristics of each species; Strong cuttings, cuttings, roots, high-quality, strong seedlings, construction of nurseries, production of commodity seedlings.
3 Nursery cultivation (a) Avoid rain. In order to ensure the quality of seedlings, it is a very good measure to adopt plastic greenhouses for rain-fence cultivation of carnations and nursery nursery. (b) Density. The planting density and cutting yield have a great relationship. Choosing a reasonable planting density is not only beneficial to the ventilation and light transmission of plants, but also conducive to the formation of a high-yielding population structure and increased effective branching; generally, a density of about 50 plants per square meter is used. Carnations should be planted as far as possible to grasp the principle of shallow planting without falling; after planting, pour well, watering the roots with roots, so that the root system and the soil full contact; if the planting too deep prone to stalk rot. (c) Field management. The root minister produced a large number of white roots, indicating that the female seedlings had survived. At this time, the water should be slowly controlled to ensure that the roots were well developed. The seedlings should be applied once every 7-10 days and sprayed once with insecticides and fungicides; When the plant grows to 7 leaves and 1 heart, it can start topping. According to the different branching ability of different species, leave 5 -7 pairs of leaves, to prepare for the development of lateral branches after harvesting. Normal-usually not used for nursery, can be used as tissue culture materials for rejuvenation, Seeds; when the lateral branch grows to 7 leaves and 1 heart, the ear can be harvested; - Mastering 3 to 4 leaves on the female parent, cuttings every 25 to 30 sticks - Fix with rubber band and place in carton or plastic box , store in cold storage at 1 -2 degrees Celsius.
(2) Carving of carnations from December to February of the year is a large number of breeding periods. The rooting time takes about 30 days; from March to April, it is 25 days, and from May to July, it is about 20 days.
1 Insert the bed and prepare to lay 20 centimeters thick pearlite plus ash in the seedbed as a cutting matrix, scrape with a wooden board, in order to meet the rooting temperature in the winter, insert a resistance wire in the slot, add 10 centimeters thick medium to the heating wire, Cut after leveling.
2 Spikes should be selected for cuttings in the cutting garden, every 25 - 30 sticks - they can be taken out, and cuttings stored in cold storage can also be taken out for cutting.
3 Hormonal treatment - Generally 500 mg / kg roots can be treated better.
4 The cutting density is about 800 per square meter, and the spacing of the rows is 2 cm x 6 cm.
5 After the cutting of the bed, it is necessary to pour the water 1 times first. Generally, there is a lot of stagnant water under the seedbed plate; in the next 1 - 2 weeks, the foliar droplets will be basically ensured, gradually starting from the 2nd or 3rd week. In order to control the moisture, from the 3rd week, spray only 1-2 times a day, and spray water to maintain the degree of evaporation to promote root development.
(3) The seedlings should be raised in time according to the rooting condition of the seedlings. - When the carnation grows to 2 cm in length, it can be carried out; spray the fungicide twice a day before; Must remove some of the seedlings that are not robust, each 100 bags - bags, each bag indicate the type, quantity, grade, origin and so on.
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, human.
