(2) Application of Phosphate Fertilizer on Foliar Peanuts have strong absorption capacity for phosphorus, and spraying calcium phosphate aqueous solution during the middle and late growth period can increase the yield of pods. 2-3kg of superphosphate, 100kg of water, stir and soak, after a day and night, take the upper layer of clear liquid application, usually every 7-10 days spray, even spray 2-3 times, each time spray about 60kg per acre. Be careful to remove the residue completely to avoid damage to the blade.
(3) Nitrogen and phosphorus are mixed in the peanut field with phosphorus deficiency and nitrogen deficiency. It can spray 1% urea and 2% calcium superphosphate mixture, which saves labor and has good effect. Preparation method: 100kg2% superphosphate Urea lkg is added to the calcium aqueous solution.
(4) Foliar application of potassium fertilizer is generally formulated with grass ash. The preparation method is to take 5-10kg of grass ash without rain, add 100kg of water and stir well, soak for 12-14 hours, take the clear liquid, which is 5%-10% of the ash leaching liquid, spray about 60kg per acre. Potassium sulphate or potassium chloride aqueous solution can also be used. The preparation method is to add 2kg of potassium sulphate or potassium chloride in 100kg of clean water, stir and dissolve to form 2% potassium sulphate or potassium chloride aqueous solution, and spray 60kg per acre. .
(5) For the combination of phosphorus and potassium, take 5kg of hay ash, add 40-50kg of water to soak, and take 2kg of calcium phosphate. Sprinkle in the soaking solution, stir well, filter out the clear liquid after half a day, and add the remaining water for 20k. Then, the filtrate is combined twice, and the water is added to 100 kg, that is, potassium dihydrogen phosphate produced by the earth method, and 60 kg per acre is sprayed, and the spraying effect is obvious when the spray is performed twice.
(6) Attention 1. The fertilization time should be determined according to the growth condition of peanuts and the growth period, and should generally be applied at the later stage of growth.
2. It is necessary to choose no windy cloudy days, or spray on the sunny day before 9:00 am and after 4 pm to increase the amount of leaf absorption and prevent damage to the leaves. After 4 hours of spraying, it should be sprayed after the rain.
3. Strictly control the concentration of spraying, the concentration is large and easy to damage the leaves, causing fat damage.
4. Spray evenly when spraying, and spray the front and back of the leaves.
Car shock absorbers are vital components of a vehicle's suspension system. They help to improve the overall driving experience by reducing vibrations and impact caused by bumps and uneven surfaces on the road. In this article, we will explore what shock absorbers are, how they work, and why they are important.
What are car shock absorbers?
A car shock absorber is a device that is designed to absorb or dampen shocks and vibrations caused by the movement of the vehicle's wheels. They are typically located between the suspension and the frame of the car and are made up of a cylinder filled with hydraulic fluid and a piston that moves up and down within the cylinder. When the wheel hits a bump on the road, the shock absorber's piston is forced up, compressing the hydraulic fluid inside the cylinder. The fluid then flows through small valves or orifices, dissipating the energy and slowing the movement of the piston.
How do car shock absorbers work?
The main purpose of shock absorbers is to reduce the amount of energy that is transferred to the car's body and the passengers inside the vehicle. As mentioned earlier, when the wheel hits a bump, the shock absorber compresses, slowing down the movement of the wheel and preventing it from bouncing back up. This allows the vehicle's tires to maintain contact with the road surface and ensures that the vehicle remains stable while driving.
Why are car shock absorbers important?
Here are a few reasons why car shock absorbers are important:
Improved safety: Shock absorbers help to improve the safety of a vehicle by keeping the tires in contact with the road surface, which reduces the risk of accidents caused by loss of control.
Improved comfort: Without shock absorbers, passengers would feel every small bump and jolt in the road. Shock absorbers help to improve the overall comfort of the ride by reducing the impact of these bumps.
Extended tire life: Shock absorbers also help to reduce the wear and tear on the vehicle's tires by preventing excessive bouncing and vibration.
In summary, car shock absorbers are an essential component of a vehicle's suspension system. They not only help to improve safety but also provide a comfortable and smooth ride. Regular maintenance and replacement of worn-out shock absorbers are crucial for a vehicle's overall performance and longevity.
