Hawthorn winter shears
Hawthorn winter pruning can promote the strong tree in the coming year, ensure the skeleton is firm, the branches are combined, the fruit is more excellent, the product is stable and longevity, and the purpose of premature birth, high yield, high quality and low consumption is achieved. It can be trimmed from November to January next year.
First, young tree pruning
1. Branches that grow obliquely or horizontally, if the growth is weaker than the main branch, the space allows growth to be retained. If the growth is strong, the methods such as circle branching, bracing, and controlling branches can be used to weaken the growth.
2. The auxiliary branches that are crossed, dense and hinder the growth of the skeleton should be removed according to the specific circumstances, so as to leave room for ventilation and light and give way to the backbone.
3, erect branches, competition branches are generally to be removed, such as fewer branches, optional growth is not strong, leaving 1/3 from the cut, and when the new shoots grow to 25 cm in May and June, many times, picking the heart, promoting branching .
4. More than three strong branches at the top of the extension branch of Wangshu. When pruning, the apex should be removed, the second branch should be weakened by the large cut, and the third branch should be used to extend the branch and make the main branch forward. To achieve the purpose of suppression before and after promotion.
5. The weak inner lychee should be removed, and the inner lychee without flower buds should be re-cut to make the branches compact.
Second, mature tree pruning
1. Retraction: For the auxiliary branches that are delayed due to slow release, they must be retracted and rejuvenated. When there is no result of the mother branch in the weak branch of the root branch, the branch should be retracted; for the extension of the single-strength growth, the branch should be retracted to promote the new branch.
2, sparse branches: timely removal of weak branches in the lower part of the base branch without flower buds; weakening and remaining strong for the peripheral results of many years of continuous and unable to form the mother branches, and thinning the weak branches of the inner scorpion and overlapping, overlapping auxiliary branch.

Medicine Peptides and protein drugs are emerging. There are now 35 important therapeutics on the market, and the development of biotechnology and biopharmaceutical companies is becoming increasingly global. Biotechnology drug research focuses on the application of DNA recombinant technology to develop peptides, proteins, enzymes, hormones, vaccines, cell growth factors and monoclonal antibodies that can be used in clinical applications. According to Parexl's Pharmaceutical R&D Statistical Source Book, there are currently 723 biotech drugs under FDA review (including phase â…° to iii clinical and FDA evaluation), 700 drugs are in early stage (research and preclinical). More than 200 additional drugs are in the final stage of approval (Phase iii clinical and FDA evaluation). The basic dosage form of biotech drugs is lyophilized. Although the efficacy of conventional preparations has long been clinically proven, they need to be injected frequently for a long time due to their short half-life, which is difficult to accept from the perspective of psychological and economic burden on patients. To this end, scholars around the world mainly from two aspects to study and develop convenient and reasonable drug delivery approaches and new preparations: (1) embedment agent and sustained-release injection. â‘¡ Non-injectable dosage forms, such as respiratory inhalation, rectal administration, nasal administration, oral administration and transdermal administration, etc. Injectable preparations of sustained-release biotechnological drugs are new dosage forms with promising applications. Some of them, such as microsphere injections of luteinizing hormone releasing hormone (LHRH) analogues which can be sustained-release for 1 to 3 months, have been on the market. This paper focuses on this kind of preparations.Main types of peptides and protein drug sustained-release preparations The research and development of peptides and protein drug sustained-release preparations can be divided into two types, namely, embedment agent and microsphere injection, from the perspective of development process and dosage form. The shape of the implant is a hollow micro-fine rod, one end is closed, the other end is open, and the rod material is non-biodegradable polymer such as ptfe. The lumen was filled with a mixture of drugs and silica gel (silastic, polydimethylsiloxane). The implant is embedded under the skin, and the drug is released slowly through the opening of silica gel matrix. The American Physicians' Handbook (PDR) contains a product called Norplant? Levo-18 ethyl norethinnes, used in family planning. The preparation, each with a diameter of 2.4 mm and a length of 34 mm, is surgically implanted in the inner side of the patient's upper arm with 6 thin rods. The drug can be released in the body in zero-grade mode for up to 5 years, and then removed by surgery after release,1.1.2 Micro-osmotic pump embedding agent The United States Alza company in the 1970s developed an embedding agent shaped like a capsule, which is embedded in the skin or other parts. The body fluid can penetrate through the shell, dissolve the interlayer electrolytic layer, make the volume expansion of the interlayer pressure to the plastic inner cavity, and promote the drug solution from the opening of the fixed speed release. Many biomolecular drugs, such as insulin, heparin and nerve growth factor, have been reported as model drugs in vivo and in vitro. Implants have positive significance for the treatment of chronic patients who need long-term medication, but it has the following defects: â‘ must be surgically implanted. â‘¡ The skeleton material of the preparation is non-biodegradable polymer, which needs to be removed by surgery after release. â‘¢ The preparation has irritation and discomfort in local tissues. Evaluation methods for polypeptide protein drugs: 1. Liquid chromatography 2. Spectroscopic 3. Solvent-based versions are easy to use, but need to be kept at low temperatures (2-8 degrees Celsius).
