Prevention and cure of rotten pepper in plastic greenhouse

First, agricultural measures 1. Control the air temperature and humidity in the shed. Application of hard plastic pipe underground water infiltration technology, independent control of wet disease prevention. With the traditional ground irrigation method, a temperature and humidity meter is attached to both ends of the shed (the temperature and humidity meter of the direct air relative humidity data is available on the market), and the temperature and humidity of the air in the observation shed are periodically measured, and the measured data and time are measured. The optimum temperature and humidity in the fertility stage were compared to guide the air cooling, temperature and humidity, and the temperature of the curtain was controlled. The temperature and humidity environment in the shed was actively controlled and controlled. The temperature in the shed during the day was controlled at 25°C2°C and 18°C ​​at night at 2°C. The relative humidity of air is 75% 5%; when the outside temperature is greater than 15°C, ventilation is gradually done day and night, and the bottom wind is placed in the front of the shed, from small to large; a tuyere is opened every 2 meters, and the brick is flatly supported and is of type "A". When the outside temperature rises to an average temperature of 16°C-18°C, bricks are placed vertically (10 cm high); at 19°C-21°C, bricks are placed (20 cm high); with the increase in temperature inside the shelter, the waist is released. Wind and wind, or shade net. The air must be smoothly ventilated, and the temperature in the shed must not fluctuate in a short period of time. 2. Manual disinfection. In the buffer room and in front of the entrance to the greenhouse, a 1.2m long and 1m wide grass mat lime disinfecting pool was constructed. Lime water was sprinkled every 15 days to keep the pool moist. Into the shed, both feet were disinfected in the pool to prevent outside bacteria from carrying. Spread the disease; pick latex gloves, and cut fruits with scissors soaked with disinfectant; equip with 0.5% potassium permanganate disinfectant bucket, and then disinfect the scissors and latex gloves to prevent germs from invading. Stain spread. 3. Increase phosphorus and potassium fertilizers. Use 2% potassium dihydrogen phosphate solution to micro-spray the stems and leaves, 30 kg per acre of fertilizer solution, 7 times a day top dressing, in order to improve the plant's resistance to disease. 4. Cover grass to reduce humidity. Spread 3-5 cm thick wheat straw wheat bran between large banks, absorb moisture and dampen moisture, reduce the air humidity in the shed, and prevent the development and harm of diseases. Second, pesticide control 1. Disease prevention and control. After colonization and survival, use 64% antiviral 400 times solution, 72% metalaxyl manganese zinc 500 times solution or 72% Duponctron 700 times solution to alternately spray the whole plant, once a day for 7 days, and continuously spray 2-3 times. Times. 2. Gray mold and Sclerotinia prevention and treatment. Peppers from the time to the pepper time with 20% of the Green Emperor 400 times solution or quick-acting 1200 times the control of gray mold; with 40% zolex 400 times or 100% of the whole plant spraying Baifen Sprouting Sclerotinia disease. 3. Soft rot control. In the early flowering and postharvest period, monitoring and control should be strengthened. 77% can be used to kill 700 times and 72% of agricultural streptomycin 3000 times alternating use, stems and leaves spray, the plant does not drop the liquid is appropriate. 4. Anthrax prevention and treatment. Into the results of the maternal stage, with 75% chlorothalonil 400 times or 70% thiophanate-methyl 800 times the disease at the peak of the new 300-times with 300 000 spray, with plants do not drop the drug is appropriate. 5. Cotton rot control. On sunny days, the whole plant can be sprayed with 400% of the anti-virus 400-fold solution. When it is cloudy or rainy (greater than 85%), it is sprayed with 20% slow-drying moxa, 250-300 g per acre, and closed in the evening. Room, igniting the agent, the next day after the sunrise, the air outlet vents and exhausts before entering the shed.

Peptides Products

An organic compound formed by dehydration of amino acids, containing carboxyl and amino groups, and being amphoteric. Also known as "peptide".
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.
A peptide is a chain of polymers of amino acids
A peptide is a chain of polymers of amino acids

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.
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
