Cucumber fluid does not have to be Sclerotinia
What is true Sclerotinia? From the sclerotia, the sclerotia is the growth of white cotton wool-like hyphae on cucumber plants, or the occurrence of gray mold in the early stages, and the development of brown murine fecal matter in the disease stage. This is a typical symptom. It usually occurs at the base of rotten stems, so the common melon strip or vinegar in production is not necessarily Sclerotinia. In fact, there are many diseases that can cause the flow of cucumbers:
I. Cucumber Scab The disease causes serious damage to young leaves, tender stems, young melons and tendrils near the plant growth point. Damage to the growing point can be rotted within 2 to 3 days, resulting in a bald pile. Leaf lesions produce chlorotic near-circular lesions, which turn brownish yellow. After the lesions are dry, they perforate and the edges appear star-like. Vine suffers from dark green water immersed in pits with slightly sunken lesions. The rough surface of the stems is sore and scab-like. After the rupture, the glue flows, and the diseased area is ulcerated in wet conditions. This can cause wilting of some stems. The melon strips began to flow, and later developed into dark brown pitted spots. The lesions were sore lesions and formed malformed melons. Diseased melons generally do not rot, when the high-moisture lesions grow gray mold layer. The disease is low temperature, low light, high humidity and easy incidence. The optimal temperature for disease onset was 15-22°C, relative humidity of air was over 90%, and there was severe disease in the roof and plants with water droplets.
Second, cucumber diseases mainly damage the leaves, stems and melon strips. The diseased leaves were dark brown in water and surrounded by large round spots. When wet, they were soft and rot. When dry, white and blue were easily broken. The stems were flooded with soft rot and contracted, resulting in fluid flow and causing wilting in the affected area. If there are several diseased parts of the plant, the whole plant will soon become wilted and dry. The melon strip suffers from water-stained, dark-green, sagging lesions that secrete milky white fluids that gradually change in amber, soften and soften, and grow white molds on the surface, giving off foul odors. The optimal temperature for disease onset is 25 to 30°C, and the onset of heavy land masses in high-temperature and rainy seasons in summer and autumn and high soil moisture in protected areas is heavy.
Third, the disease of stem disease, leaves, melon strips. The lesions centered on the stem segments close to the rhizomes were light brown in water, and the tissues were softened and flowed, resulting in cracks. The stems of the stems were dry, and the lesions were longitudinally disintegrated. The plants were withered and withered when severe. Leaf lesions develop from the leaf margin inward into a "V" shape or near-brown lesions that are easily broken when dry. Melon sensation produces yellowish chlorotic spots. As the disease progresses, the lesions are brown and the melons are deformed and bent, sometimes overflowing with amber. The characteristic of the blight is that black spots appear on all lesions. The optimum temperature for the growth of pathogenic bacteria is 18-25°C, and the relative humidity of air is more than 85%. In continuous cropping, the plants grow weak and the bad drainage blocks are seriously affected.
How to prevent the flow of cucumber? The following methods can be used:
1. It can be used to prevent and cure by chemical agents such as Shigong and Alu copper. 2. Reduce the humidity of greenhouses: When watering, it is necessary to pour water in small quantities and choose to water at noon on sunny days. When cloudy days, aerosols can be used to prevent and control various diseases and increase air humidity. 3. Cucumber fluid may be accompanied by cucumber rot or gray mold, so it should be added during the use of Botrytis or quick-acting agent to prevent GuaZi from getting infected again. The key to preventing and controlling the occurrence of this disease is to control the air humidity, especially in the continuous cloudy weather, and pay more attention to strengthening the ventilation and reducing the humidity in the shed while maintaining the temperature in the shed.
The name "three yellow chickens" was given by zhu yuanzhang. In the national ministry of agriculture's authoritative book, "Chinese poultry Chronicles", the first, the chicken is a family of natural grazing. Its meat is tender, delicious, rich in nutrition and enjoys a high reputation both at home and abroad. It has the characteristics of small size, "three yellow" (feather yellow, claw yellow, beaked yellow), strong survival ability, high egg production and tender meat quality.
Body feathers with yellow, neck feather are golden rooster, main wing feathers red with black, black tail feathers, hen the main wing half yellow and black, black tail feathers, hackle inclusions mottled black and gray plumage. The beak is yellow, single crown, high crown, 5 ~ 7 crown teeth. The crown and flesh are bright red, the eyelids are thin, the rainbow color is orange, the ear color is yellowish. The shin and PAWS are yellow and no feathers. Compact, well-proportioned, small and delicate, with a straight back, and a tight, rounded tail, like "yuanbao". The head is of moderate size.
Chicken is compared with mutton and beef, with high protein content and low fat content. In addition, chicken protein is rich in essential amino acids, which are very similar to the amino acid spectrum in egg milk, so it is a source of high quality protein. The protein content of the chicken is different according to the location, the skin and the skin without the skin. The order of the chicken is roughly the skin of the chicken, breast and thigh meat. Chicken skin has a lot of lipids, so you can't think of chicken with skin as a low-calorie food.
Chicken is also A good source of phosphorus, iron, copper and zinc, and is rich in vitamin B12, vitamin B6, vitamin A, vitamin D, and vitamin K.
Chicken and beef, lamb, lipid, contains more unsaturated fatty acid, linoleic acid and linolenic acid, can reduce the body of the possible adverse health effects of low density lipoprotein cholesterol.
The edible effect of three yellow cock
Chicken has a high digestibility and is easily absorbed by the body. It has the effect of enhancing physical strength and strengthening the body.
Modern society is busy everyday, often in sub-healthy white collar better eat a few more, to enhance immunity, reduce the disease probability. Chicken with temperature in the qi, tonify deficiency repair essence filling pulp, benefit and loss of function, used in the treatment of consumptive emaciated, virtual food less, diarrhea dizziness, palpitation, irregular periods, less postpartum milk, diabetes, edema, and other symptoms.
Can alleviate the symptom such as frequent urination, deafness, and lack of precision due to insufficiency of kidney.
It has anti - oxidation and certain detoxification. It has a good effect on improving the function of the mind and promoting the development of children's intelligence.
Taboo on the consumption of three yellow chickens
People with cold fever, excessive internal fire, severe phlegm, obesity, people with swelling of the fever, high blood pressure, high blood lipids, cholecystitis and cholelithiasis.
Chicken sexual temperature, help fire, liver Yang and oral erosion, skin swelling, stool is not suitable for food.
The patient of arteriosclerosis, coronary heart disease and high blood fat do not drink chicken soup.
Cold with headache, lack of energy, hot people avoid chicken, chicken soup.
