Pay attention to the prevention of greenhouse virus disease
With the increase of temperature in the spring, the squash virus disease enters the peak period of onset. In particular, greenhouses with extensive management and unfavorable supply of fertilizer and water are prone to disease, and vegetable farmers should do preventive work.
First, the symptoms
In the early stage of disease, dark green patches appear on the leaves. As the disease gradually worsens, the upper leaves of the diseased plants are chicken-like, the plants are dwarfed, the new leaves show bright veins and mosaics, the leaves are unevenly colored, the leaves are small, and the depths of the leaves are not deep Yellow leaf margin, shrinkage, diseased melon, no melon or melon malformation.
Second, control methods
1. Eliminate locusts. Ascaridae is an important vector for transmitting viral diseases, so controlling aphids is one of the key measures to prevent viral diseases. Can use 2.5% deltamethrin, 10% imidacloprid wettable powder 1500 times, 50% anti-inferiority WP 800 to 1000 times alternating spray control, even spray 3 to 4 times, interval 7 to 10 days, conditional The place can also install insect nets to prevent locusts from entering the shed.
2. Reduce contact and transmission. Viral diseases can be transmitted through plant wounds. Therefore, the row spacing should be increased in cultivation to minimize the wounds caused by agricultural operations. Farming operations should follow the principle of the first strain after the strain. For early maturation of zucchini, it is not necessary to burp and avoid causing wound transmission.
3. Strengthen fertilizer management to prevent premature aging. Juvenile summer squash seedlings are susceptible to viral disease, and in the cultivation, fertilizer and water management must be strengthened to avoid dehydration due to lack of water. In the hot season, the number of watering can be appropriately increased, and the ground temperature can be lowered. Where necessary, shade can be taken to prevent premature aging of the seedlings.
4. Chemical control. In the early stage of disease, 20% virus A wettable powder 500 times solution or antitoxic agent No. 1 300 times solution can be sprayed every 7 to 10 days and sprayed 3 to 4 times.
Colon Hydrotherapy Machine Principle:
The Colon Hydrotherapy Machine adopts the non-intrusive method to provide a safe and comfortable therapy, and it can operated easily; the user only need to hold the are-shape hydrotherapy nozzle and put it on the anus gently, the treated pure water with constant temperature and pressure will flow into the colon from the anus.
a lubricant layer between the intestinal wall and feces forms soon after water enters the colon; then the impacted feces and toxins will be evacuated through natural excretion mechanisms by decomposing the impacted feces, and promoting the squirm of large intestine.
The process enables a quick and thorough defecation. It is completely painless, non-toxic and free of side effects. Besides, the ozone generator in the system can provide ozone water for gynecologic and skin sterilization.
Colon Hydrotherapy Machine Function:
Get rid of constipation: colon hydrotherapy system will dissolve and dilute impacted feces, and stimulate the natural defecation function. Eliminate impacted feces and toxins: colon hydrotherapy system adopts physical method to clean out the impacted feces and toxins, thus it will reduce risk of
[autointoxication".
There`re not only the residues of digested food but also a lot of toxins, such as ammonia which may induce hepatic coma, hydrogen sulfide affecting the nervous system, methylindole leading to cancer, botulinum toxin, Tan toxic alkali, benzene, formic acid, butyric acid and so on. With the growing age, feces and toxins gradually accumulate in the body;
Been absorbed into the blood system by the intestinal mucosa, they will cause damage to the organs, meanwhile, lead to digestive system diseases and skin problems, even though make blood pressure problem, heart disease, Alzheimer`s and other symptoms worse. Impacted feces accumulate in the colon for a long time is an important inducement to the colorectal cancer.
Gynecologic and skin sterilization: colon hydrotherapy system (except comfort type) has ozone generator to produce ozone water for sterilization of harmful bacteria. Except for removing surface skin bacteria, it can also used for killing harmful bacteria which may cause gynecological inflammation, so it can be used for the treatment of vulva inflammation.
