1. The density of seedling leaves or seedlings of red seedlings is too large or the malnutrition of each plant is caused by live seedlings or leaves of seedlings. Prevention and control measures: Immediately seedlings, to stay dense and thin, to stay weak strong, and make-up 1-2 times available fertilizer, topdressing urea 5-8 kg per mu or thin faecal water 400-500 kg, to promote seedling growth. 2. Nitrogen-deficient and yellow-leafed rapeseed lacks nitrogen. The plants are short, the new leaves are born slowly, the leaves are small, the leaf margins are generally red, and the middle is yellow, forming yellow and red leaves. Prevention and control measures: Urea 8-10 kg or ammonium bicarbonate 20 per mu. - 30 kg, 7.5 kg of human waste can also be used to pour water, can also use 1% - 2% urea solution 50 kilograms of foliar spray, and even spray 2-3 times. 3, phosphorus deficiency purple red rapeseed is very sensitive to phosphorus response, seedlings are more prosperous. The lack of phosphorus in rape can make the plants grow slowly, the leaves are small and thick, the number of leaves is reduced, and the edges and petioles of the leaves are purple, forming purple leaves. Prevention and control countermeasures: Topdressing superphosphate 20-30 kg or diammonium phosphate 6-8 kg per acre, and spraying 50 kg of potassium dihydrogen phosphate 0.2% on the foliar, spraying 2-3 times. 4. Potassium-deficient potassium deficiency rape begins with the old leaves and then develops into the new leaves. At the beginning, it was a yellow spot, and the edges of the tip gradually appeared brown spots or brown spots; the leaves became thicker, harder and brittle, showing a “burn-like†appearance. Countermeasures: Topdressing potassium chloride 8-18 kg per mu or spray 0.2 kg of potassium dihydrogen phosphate solution 50 kg, and spray 2-3 times. 5, boron-deficient blue-violet rapeseed leaf margin rewinding, rhizome expansion, blue and purple spots appear on the leaf surface. Countermeasures: 80-100 grams of borax per acre 60-70 kg of water spray, and even spray 2-3 times, can also be combined with top dressing 500-100 grams per acre. 6. When the drought-refracting red rapeseed encounters drought at the seedling stage, the lack of soil moisture will make it difficult for the roots of the oilseedling to suck up and absorb water, resulting in the slow growth of the rapeseed, the shortness of the plants, and the turning of the leaves into light red. Countermeasures: In case of watering in time, furrow irrigation should be adopted, and flooding should not be flooded, otherwise it is easy to cause rot-root dead seedlings. 7, waterlogging, dark red leaves before winter, too much rain, or paddy field transplant, poor filtration, resulting in waterlogging injury, dark green leaves, and some will be dead root rot. Countermeasures: Timely ditch the water, reduce the groundwater level, do a good job of cultivating the loose soil, improve the ventilation conditions, promote the vitality of the root system, and promote seedling growth. 8. Freezing damage to red leaf rape can cause freezing and reddening of leaves in the winter when sudden cooling to below 0°C is encountered. Countermeasures: Combine with cultivating and arranging ditch, planting soil and removing roots, adding organic fertilizers to reduce the occurrence of frost damage. 9. Insect pests Red leaf rape is seriously damaged by aphids during its growth, and it can also cause reddening of leaves, and the leaves shrink and become stiff. Countermeasures: Use 50% anti-inferiority WP 15g or 2.5% emulsion liquid to kill 30ml per mu and spray 50kg of water.
Electrosurgical Pencil
An electrosurgical pencil, also known as an
electrocautery pencil or diathermy pencil, is a medical device used in surgical
procedures to cut, coagulate, or vaporize tissue. It is typically handheld and
resembles a pencil in shape, with switch button on the handle that activates
the electrical current.
The electrosurgical pencil works by
delivering a high-frequency electrical current to the tissue through a wire
electrode. These current heats up the tissue, causing it to either cut or
coagulate, depending on the mode that been selected.
