Liu Cun-shou smoked method said that fruit farmers can use the method of antifreeze smoke at flowering, the effect of frost damage is very good, the formulation of the aerosol agent is 20% ammonium nitrate, sawdust or residual grass 70%, waste diesel 10%. The aerosol can be placed in 3 to 4 piles per acre, placed on the top of the wind or placed evenly in the vineyard. He reminded that when the temperature of 2 meters above the vineyard falls to about 2 degrees Celsius, it can be ignited and smoked. In early spring, Liu Cunshou told reporters that in areas where late frost occurs frequently, fruit growers can use early spring irrigation to reduce ground and tree temperatures, delay germination and flowering, and avoid frost damage. Spraying antifreeze Liu Cunshou said that the fruit growers can spray 2116, plant disease-resistance, 863 antagonism agent and other plant cell membrane stabilizers and Polylysine and other amino acid series of microelement fertilizers to increase the toughness of the cell membrane and improve the vine trees. The cold resistance of the body can also be sprayed with homemade antifreeze. Antifreeze can use 8 parts of agar, 3 parts of glycerin, 43 parts of glucose, 45 parts of sucrose, 2 parts of other nutrients (including fertilizer and phytohormones), and 2000 parts of clear water. Liu Cunshou suggested that when preparing antifreeze solution, fruit growers should first soak the agar with a small amount of water for 2 hours, then heat and dissolve, and then add the other ingredients, and mix it until it is ready for use.
It can be used for surgical operations, patient treatment; epidemic prevention and inspection in public places; disinfection in virus-contaminated areas; and can also be widely used in military, medical, chemical, environmental protection, transportation, epidemic prevention and other field
By setting a protective collar, the neck of the operator can be kept warm and protected. The provision of a hand guard is helpful for the surgical staff to temporarily place their hands in the hand guard while waiting during the operation, which plays a protective role and is more in line with the principles of aseptic operation and occupational protection. surgical gown,disposable surgical gown,personal protection,medical equipment Shanghai Rocatti Biotechnology Co.,Ltd , https://www.ljdmedical.com
By setting the shrinking cuffs, it is beneficial to make the cuffs fit the wrists, prevent the cuffs from loosening, and prevent the gloves from slipping off during the operation and the operator's hands are exposed to the gloves.
The design of the new humanized protective surgical gown has been improved in the key areas of the gown. The forearm and chest area are double-thickened, and there are handguards in front of the chest and abdomen. By arranging reinforcing sheets (double-layer structure) in key areas, it is beneficial to improve the water-permeability of surgical gowns and improve safety.
How to Prevent Spring Frost Damage in Vineyards
In spring, it is the time when the vine sprouts and grows. In the event of a cold spring, it will have a greater impact on the vines that have begun to sprout. Therefore, farmers must do preventive work at this time. Recently, the reporter interviewed Liu Cunshou, associate professor of the School of Resources and Environment at the Northwest A&F University, and told him to tell the farmers about the vineyard's measures to prevent “cold springâ€.
