Cucumber seedlings have begun. The problems that often occur in cucumber seedlings are the growth of cucumber seedlings, aging, rooting, etc. These problems are generally caused by improper management. We need to analyze the specific situation and find out the corresponding solutions. Method. Today, I will talk to you about these problems that often occur during cucumber seedlings.
Three problems often appear in cucumber seedling stage
1, the seedlings are long
Cucumber seedlings are characterized by long internodes, thin cucumber leaves, slender stems, and few roots. Cucumber seedlings have poor immunity and are prone to disease, and slow seedlings after planting. In addition, seedling madness also directly affects flower bud differentiation.
Reason: The reasons for the madness of seedlings include excessive temperature, insufficient light, and sufficient nitrogen and water in the seedlings.
Solution: It is to enhance the light, reduce the temperature, properly control the watering and spray the phosphorus and potassium fertilizer. In addition, the seedling stage can be sprayed with schizophrenia, adding 20--50 microliters of chlormequat per liter of water, which can effectively control the madness.
2, seedling aging
Cucumber seedlings appear aging seedlings, which is the most common problem of cucumber, mainly characterized by small leaves, thin stems, few roots, slow seedlings after planting, and it is not easy to set roots, plants grow weak, leaves yellow, easy, delay growth period And delayed the results, the number of abnormalities increased, seriously affecting the yield of cucumber.
Reason: The cause of aging of seedlings is mainly due to severe water shortage at seedling stage and low temperature, and growth and development are excessively inhibited.
Solution: Measures to prevent seedling aging are mainly to provide suitable temperature and moisture conditions for seedlings to promote normal growth of seedlings. Especially when raising the seedlings at a relatively low temperature, it is necessary to raise the temperature of the seedbed as much as possible, and to properly water and refine the seedlings. If aging seedlings are found, 10-30 μl/L of gibberellin can be sprayed, which can effectively promote the normal growth of seedlings.
3, root
Cucumber root is another common problem in the nursery stage. It is a physiological disease. It mainly refers to the rotten death of the roots of the seedlings, which causes the above-ground parts to stop developing. The leaf color changes from green to yellow, and the whole plant is dead.
Reason: The main reason for the occurrence of alfalfa roots is that the moisture of the seedlings is too high, and the water is saturated for a long time. The soil is excessively sticky and lacks oxygen, which makes the roots unable to carry out normal metabolism.
Solution: The measures to prevent rooting are mainly to control the amount of water in the seedbed and avoid the accumulation of water in the seedbed. In the event of excessive watering, excessive humidity, water in the seedbed, causing roots, it is necessary to ventilate and dehumidify in time, and then cultivating the pines to increase the amount of soil evaporation or to absorb moisture.
The above are three common problems and solutions for cucumber seedlings. For the reasons for the emergence of these three diseases, Xiaobian also introduced the above and shared the solutions. Now it is a good time for autumn cucumber cultivation. If you have the above three diseases, you can refer to the solution introduced by Xiaobian. I hope that the contents of Xiaobian can help the majority of cucumber growers.
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).
