Today is the first day of the lunar calendar on November 1st, and it is also the heavy snow in the 24th solar terms. Some people say that the snow is as big as the name suggests. It is a large amount of snow. The ancients said: "The big ones, Sheng also, and now Xuesheng also." At this time, the snow tends to be large and wide, so the name is heavy snow.
It is reported that at present, the lowest temperature in most northern regions of China has dropped below zero, and farmers' friends are still reminding themselves to keep warm while doing agricultural activities.
In the Lingnan area, because it is in a subtropical climate zone, it is often “one night into the winterâ€. Today, it coincides with heavy snow and cool down. The Lingnan area has been successful in winter. The mode of low temperature and light rain will definitely make you tremble. Not only do people need to add clothes, but winter crops must take effective measures to prevent freezing damage.
I. Anti-freezing measures for crop crops
1. Physical protection: smoke and cover.
When the low temperature comes, it can generally ignite the smoke, make the smoke heat release, and increase the temperature between the plants; if it is a small area crop, it can be covered with vegetables such as straw, mat, loach, plastic cloth and grass ash. The heat in the ground field is not easily lost.
2. Chemical protection: The use of pharmaceutical agents increases the cold resistance of plants.
Before the temperature is lowered, anti-freezing agents and plant additives are sprayed in the field to enhance the ability of the crop to resist cold.
Second, crop antifreeze recommended
1. Multi-effect antifreeze
Features:
Increase the ability of plants to retain water and drought, reduce the damage of freezing damage, reduce the rehabilitation effect on moderately mildly damaged plants, and improve crop yield and quality.
Antifreeze effect can be achieved about 4 hours after spraying.
Spray 2-3 times to prevent vegetables, fruit trees and flower buds from freezing.
Specification: 100ml/bottle
2. Antifreeze Doctor
Features:
Containing seaweed actives, it can form a protective film on the surface of plants, induce the plant to produce anti-freezing factors, reduce the occurrence of freezing damage, and simultaneously improve the crop's resistance to mites, droughts and diseases, and at the same time repair the injured cells of the crops. Light crops have a good recovery.
Specification: 200ml/bottle
3. Green Heng Tianbao
Features:
The active substance in the powerful and high-efficiency increasing agent of Tianbao (DCPTA) can directly act on the nuclear regulatory genes, increase the chlorophyll content by 10-20%, increase the photosynthetic strength by more than 30%, enhance the synthetase activity, accelerate plant development, and enhance crop drought resistance. Antifreeze, pest and disease resistance, lodging resistance.
Specifications: 10ml / bag, 100ml / bottle, 500ml / bottle
4. Pure rich
Features:
The use of natural plant-derived humic acid through a unique fission, making humic acid macromolecules into small molecules absorbed by plants, can make plants more resistant to stress and higher yield.
Specification: 250ml / bottle
5. Vegetable
Features:
Using unique biochemical chelation technology, it perfectly solves the antagonistic effect between 14 nutrients and provides comprehensive power for crop growth.
Under the premise of enhancing photosynthesis of crop leaves, the nutrients are quickly transferred to fruits and roots, greatly improving crop activity.
Specification: 250ml / bottle
The above is the main points of anti-freezing measures for crops and anti-freezing drugs. However, Xiaobian should focus on reminding farmers and friends that drugs can not be used indiscriminately. It is necessary to consider the actual situation of your local area. You can consult with your old farmers. Antifreeze.
Covid Test
Novel Coronavirus belongs to ß genus. Sars-cov-2 is an acute respiratory infectious disease. People are generally impressionable. Currently, novel coronavirus infected patients are the main source of infection; Asymptomatic infected people can also be the source of infection. According to the current epidemiological investigation, the incubation period is 1 to 14 days, usually 3 to 7 days. The main manifestations are fever, fatigue and dry cough. In a small number of cases, nasal congestion, runny nose, sore throat, myalgia and diarrhea occur. In the acute phase of infection, antigens are usually detected in upper respiratory tract specimens. Rapid diagnosis of SARS-COV-2 infection will help health care workers treat patients and control the disease more effectively.
Benefits are: Rapid detection of SARS-COV-2 antigens in 15 minutes facilitates patients to make rapid treatment decisions ;.Simple, time-saving procedure provides all necessary reagents, no equipment, sensitivity and specificity high content of 20 test tapes. 20 Sterile swabs. 20 sample extraction tubes with 2 buffers.1 package insert
