Rescue fruit tree phytotoxicity technology

The damage of pesticides to plants is divided into acute and chronic. Acute phytotoxicity is manifested within a few hours to a few days of spraying, such as leaves, fruits, spots, yellowing, chlorosis, withering, rolling leaves, deciduous fruit, and constricted clusters. Chronic physiology can only be manifested after a long period of time, such as weak photosynthesis, flower bud formation and delayed fruit ripening, small, deformed, and deteriorated flavor and color. Once the fruit tree is found to be phytotoxic, the following measures should be taken immediately to save it.
1. Spray potassium permanganate. Potassium permanganate is a strong oxidant that has oxidative decomposition effects on a variety of chemicals. Spraying 6000 times potassium permanganate solution can effectively alleviate the phytotoxicity.
2. Rinse with water. Most chemical agents are not resistant to water scouring. If the application concentration is too large and the phytotoxicity is caused, the sprayer should be used to fill the water, and the leaves of the fruit trees should be washed repeatedly to wash away the residual agent on the surface of the leaves.
3. Suspend the use of similar drugs. Before the phytotoxicity is completely relieved, try to reduce the use of pesticides, especially the same kind of pesticides should be stopped, so as not to aggravate the phytotoxicity.
4. Follow the fertilization water. After the phytotoxicity of the fruit trees, the quick-acting fertilizer should be supplemented with watering, and the loose soil should be ploughed. At the same time, 0.3-0.5% urea and 0.2-0.3% potassium dihydrogen phosphate should be sprayed on the foliage to improve the nutritional status of the fruit trees and enhance the root absorption capacity. Operation should be carried out before 10 am and after 4 pm.

Differential Bearing

Deep Groove Ball Bearings

Deep groove ball bearings The out looks of them are nearly the same,the only different is the size,you may need other models please check the following table for reference.are the most widely used bearing type and are particularly versatile.
They have low friction and are optimized for low noise and low vibration which enables high rotational speeds.
They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.

Deep groove ball bearings are divided into the following series: 6000series, 6100series, 6200series, 6300series, 6400 series, 6700 series, 6800 series,6900 series,16000 series etc.
