Strawberry is a multi-herbaceous plant with short plant shape, unique leaf shape, red and white flowers, and sweet aroma. It has high economic value and ornamental value, can purify the air and beautify the environment, and enrich people's taste. Potted strawberry technology is as follows: First, choose the container. The available diameter is 21 to 33 centimeters of masonry pots or porcelain pots or wooden boxes, the size of which depends on the number of plants to be planted. There are water seepage holes at the bottom of the tank. Plant pots should be soaked in water before planting. ?? Second, the choice of species. General cultivars can be selected, but it is best to produce seasonal strawberry varieties. Third, configure nutrition soil. Strawberry Xisha sex, good permeability of fertile soil. Therefore, the ideal basin soil is the humus of the broad-leaved forest surface. This kind of soil contains many organic substances, many nutrients, loose soil, and good water absorption and drainage performance are beneficial to the growth of strawberries. Nutritious soil can also be artificially prepared. The proportion of soil, fertilizer and sand is 1:1:1, that is, 1 part of fertile garden soil is used, 1 part of decomposed chicken, duck or sheep manure and 1 part of river sand are added; The soil and sand are all preferably crushed and then mixed with 2% to 3% of superphosphate. The prepared nutritive soil can be disinfected with a 0.3% potassium permanganate solution before being loaded. Conditions can be properly added to the cake fat. Put some broken bones, fish meal, hoof shoulders, egg shells and the like in the pelvic floor. Fourth, seedlings selection. To plant young seedlings, we must choose new seedlings from the same year, with no pests and diseases, developed fibrous roots, more white roots, and full top buds. We have 3-5 leaves, short petioles, and medium-sized, robust seedlings weighing about 25 grams per plant. Fifth, planting methods. When planting, the root should be uniform with the back of the bow and the stem should be upright. The bowl is first filled with some nutritious soil, and the roots are stretched around to continue filling. The depth of planting is based on the principle of “being rootless and not burying the rootsâ€. The soil will be solidified and the seedlings will be fixed. Do not overfill the basin soil, keep the distance between the soil surface and the basin mouth at 3 or so, so that the soil can be cultivated later. Before planting, dilute the solution with naphthaleneacetic acid or ABT rooting powder 5010-6 for 1 hour to increase the survival rate. Immediately after planting, irrigating the water. After the water seeps, the fibrous roots exposed on the outside shall be covered with soil, and the seedlings shall be raised gently and then compacted so that the roots and soils are combined closely and in depth. ?? Fat ice management. Strawberry has higher requirements for fertilizer and water, especially for the four seasons. The flower buds are continuously formed in one year, and flowering results require multiple fertilizing ice to meet the needs. Potted strawberry compost can use compound granular fertilizer or long-acting flower fertilizer, and can also add cake water, fish miscellaneous animals, animal hoofs, and viscera of poultry, etc., and fully ferment fermented and decomposed, combined with watering and fertilizing, and apply it once every 10 days or so. Work. For the application of chemical fertilizers, foliar spray fertilizers such as spraying 0.3% potassium dihydrogen phosphate may be applied in the morning or evening. In outdoor potted plants, the leaves are vulnerable to water shortage. It is necessary to pour water 1 time sooner or later and keep the soil moist. In hot summer days, flower pots should not be exposed to direct sunlight. They should be placed in a dry and ventilated place. In the middle of the day, water should be poured one more time, but do not use water or tap water with low water temperature. ? Seven, plant management 1, remove the stolon. Sorghum consumes a lot of nutrients. Newly-inoculated young shoots must be removed in time to reduce nutrient consumption and improve fruit quality. If it does not allow the result, the stem can be left behind, so that it grows out of the foliage and droop naturally, forming a strawberry bonsai like spider plants. ?? 2. Remove old leaves and pests and leaves. The leaves of strawberry are constantly updated. The presence of old leaves is not conducive to plant growth and development, and is prone to pests and diseases. When the lower leaves of the plants were found to be leveled and began to turn yellow and the base of the petiole began to change color, the leaves should be removed promptly. ?? 3, thinning and thinning fruit. When the strawberry enters the flower and fruit stage, care should be taken to remove weak and thin fruits and malformed fruit. Each plant retains 2-3 inflorescences. Each inflorescence retains 4-5 fruit. After fruit set, the grass is cleaned under the fruit to increase the color of the fruit. Degree, to avoid rotting fruit, improve fruit quality. 4, control of pests and diseases. The main pests of potted strawberries are aphids, whiteflies, and leafhoppers. Attention should be paid to timely control. Eight, change soil basin. Every year, a new stem is picked up from the strawberry, and a new root is made at the base of the new stem, while the old root in the lower part is gradually dying. Since the stems and roots of strawberry should be moved upwards every year, in order to ensure a suitable environment for hair rooting at the base of new stems, earth must be grown at the base of the new stems, and a layer of soil must be added to the pots to raise the thickness of the soil to reveal the height of the shoots. If conditions are available, change the basin before and after the beginning of spring in the spring result. Add new nutrient soil to the new basin. Pour the plants out of the soil and put new ones in the basin. Slightly deeper. If the plant has been in fruit for two years, changing the pot can shake off the earth around the plant, exposing the roots, carefully removing the root-like stems of the new roots, which are like inclusions, and then transplanting them into new pots slightly larger than the original pots. Play the role of the updated rejuvenation. ?? Nine, wintering and breeding. Potted strawberries are placed outdoors and can be moved into sunny indoor areas in winter or on closed balconies to the south. The cold winter also uses plastic film insulation. It is also possible to dig trenches on the ground and discharge them in pots. An organic compound formed by dehydration of amino acids, containing carboxyl and amino groups, and being amphoteric. Also known as "peptide".
Three, is related to the biological body of a variety of cell functions of biological active substances. Hundreds of peptides have been found in living organisms, which are essential participants in the body's complex physiological activities. All cells can synthesize peptides and their functional activities are regulated by peptides. It involves hormones, nerves, cell growth and reproductive fields, and its importance lies in the regulation of various systems, organs and cells in the body. The physiological and pharmacological effects of enzymatic polypeptides are mainly to activate related enzymes in vivo, promote the permeability of intermediate metabolic membrane, or affect specific protein synthesis by controlling DNA transcription or translation, and eventually produce specific physiological effects or play their pharmacological effects. Peptide is better than amino acid, one is faster than amino acid absorption; Second, it is absorbed by the body in a complete form; Third, active absorption (amino acids are passive absorption); Fourth, low consumption, compared with amino acids, peptide absorption has the characteristics of low consumption or no energy consumption, peptide absorption through the duodenum, directly into the blood circulation, their own energy nutrition transported to various parts of the human body; Fifth, peptide absorption is less than amino acid, with the characteristics of unsaturated; Sixth, there are only 20 kinds of amino acids, with countable functions, while peptides take amino acids as substrates, which can be synthesized into hundreds of thousands of kinds.
It is mainly divided into medical polypeptide drugs, peptide antibiotics, vaccines, antimicrobial peptides for agricultural use, small peptides for feed, cosmetics for daily use, soybean polypeptides for food, corn polypeptides, yeast polypeptides and sea cucumber peptides. buy peptides,peptides benefits,peptides bpc 157,peptides buy,peptides cjc 1295 Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptide-nootropic.com
Two, one of the amide. It consists of two or more amino acids joined by the amino group of one amino acid to the carboxyl group of the other. An amino acid cannot be called a peptide, nor can a peptide be synthesized, but must be a compound of two or more amino acids linked by a peptide bond. Compounds where two amino acids are linked by a peptide bond are called dipeptides; A compound with three amino acids linked by peptide bonds is called a tripeptide, and so on, a compound with thirty-four amino acids linked by peptide bonds is called a thirty-four peptide.

From the functional point of view, can be divided into antihypertensive peptide, antioxidant peptide, cholesterol lowering peptide, opioid active peptide, high F value oligopeptide, food strong taste peptide and so on.
Active peptide, and nutrition, hormone, enzyme inhibition, regulation of immunity, antibacterial, antiviral, antioxidant has a very close relationship. Polypeptides are generally divided into: polypeptide drugs and polypeptide health products. Traditional peptide drugs are mainly peptide hormones. The development of peptide drugs has been developed into various fields of disease prevention and treatment, especially in the following fields. [2]
Antitumor polypeptide
Tumorigenesis is the result of many factors, but ultimately all involve the regulation of oncogene expression. In 2013, many tumor-related genes and regulatory factors have been discovered. Screening peptides specifically bound to these genes and regulatory factors has become a new hot spot in the search for anticancer drugs. For example, somatostatin has been used to treat endocrine tumors of the digestive system; American scholars found a hexapeptide can significantly inhibit adenocarcinoma in vivo; Swiss scientists have discovered an octapeptide that induces apoptosis in tumor cells. [2]
Antiviral polypeptide
By binding to specific receptors on host cells, viruses adsorb cells and rely on their own specific proteases for protein processing and nucleic acid replication. Therefore, peptides binding to host cell receptors or active sites such as viral proteases can be selected from the peptide library for antiviral therapy. In 2013, many small peptides with antiviral properties have been screened from peptide banks in Canada, Italy and other countries, and some small peptides have entered the stage of clinical trials. In June 2004, the Chinese Academy of Sciences institute of Microbiology came out of the news, which was undertaken by the Chinese Academy of Sciences known
