In recent years, with the occurrence of corn schistosomiasis more common, the loss of food and feed value at the onset of the panicle should be well prepared for prevention and treatment as soon as possible.
Corn schistosomiasis may occur in all young parts of the ground during the whole growth period of corn. The diseased area is tumorous. The size of the tumor varies depending on the site of the disease. The tumor on the leaf blade is small, and the tumor on the ear or stem section can often reach the fist size. When the tumor was immature, it was a group of white soft tissue, and the outer layer was covered with a thin film. After maturation, all the tumors turned into black powder (diseases of chlamydospore) and the black powder was scattered after the film was cracked. The pathogenic bacteria use the chlamydospores to overwinter in the soil, diseased bodies, and composts and manures, and they mainly use soil-borne diseases. The seeds can also carry the bacteria. The chlamydospore can be repeatedly infested when the wind passes onto the plants to produce germs. High temperature and high humidity, growth and tenderness, drought, long-term continuous cropping, partial application of nitrogen fertilizer, pests, and storms caused by wounds and other factors can easily lead to disease. Non-hard-grained varieties and their varieties had thick, long, and tight varieties with poor disease resistance.
To control corn schistosomiasis, the following measures should be taken: selection of disease-resistant varieties; use of 40 ml of 20% triadimefon EC per kilogram of seed; timely deep plowing to reduce the initial infestation source; increasing potassium fertilizer, organic fertilizer should be fully cooked ,Prevention of bacteria;Timely prevention of corn borer and other pests,reduction of wounds;High temperature and humidity or dry weather for a long time, can be sprayed with 1:1:120 Bordeaux fluid prevention; Grab before the rupture of the tumor film to bring out the depth of field after the early rupture Buried or incinerated, and wiped the wound with thin slurry; cleaned the pasture, reduced the number of sick and fallen leaves, and seriously affected the field for more than 3 years of rotation.
disposable use of drainage tubes for medical purposes (silica gel) purpose: used for suction sealing wound, suitable for the drainage of blood and fluid during and after surgery. We have patent of drainage tubes for medical purposes for anti flow and anti leakage.
By discharging the air in the drainage bottle to form a negative pressure with the outside, the waste liquid at the other end of the drainage tube flows into the drainage bottle through the drainage tube to achieve the purpose of drainage.
