Big cherry fruit picking tree management
After the fruit is harvested, the management of the cherry tree must be grasped, and the following aspects should be done:
1. Thinning and twisting
After the cherry fruits are harvested, the overdense branches, weak branches and diseased branches should be cleared or shortened to improve the inner bore lighting and reduce consumption; the vigorous long branches and competitive branches are reversed by 180 degrees to weaken the growth momentum, Promote the differentiation of flower buds; those that are still vigorously growing after twisting should continue to lightly top the heart, ease the tree vigor, and improve the fruit setting rate and fruit quality.
2. Pull in time, chemical control
Pull the strong branch to a place where there is space, the angle of the main branch should be kept at 80 degrees to 90 degrees; the vertical distance of the main branch in the same direction is 80 to 100 centimeters; the overlapping branches can also be separated by 15 Spray 2~3 times of paclobutrazol 200~300 times solution or PBO180~200 times solution every day.
3. Timely supplement
About 10 days after fruit harvesting, a comprehensive N, P, K potassium fertilizer for fruit trees was applied in a timely manner. As a result, each tree was applied with about 1 kg, and water was applied after fertilization.
4. Foliar spraying
One week after harvesting, foliar fertilizer was sprayed 1 or 2 times in combination with pest control to delay defoliation and promote good flower bud development.
5. Irrigation
Fertilization and irrigation should be applied immediately after fruit picking, and the irrigation volume should be just the surface of the ground. The general soil moisture should be kept at about 70% of the field water holding capacity.
6. Early application of base fertilizer
Fertilization should be carried out in early September. As a result, 3 kg of biological bacterial fertilizer + 1.5 kg of compound fertilizer are applied to each tree, which provides a strong guarantee for flowering and fruit setting in the coming year.

Steel Grating
The steel grating be welded to products . Normally, hot galvanizing will be carried out after end welding process. The range PH6 to PH12.5, a stable protective film will be formed on the zinc surface, the hot dipped galvanized steel grating has good anti-corrosive property. Of course, the steel grating also have other surface treatment, for example painted and powder coated .
Steel grating can be cutting to different kinds of shape as per your special needs.
Steel grating including flat grating, 'I' shape grating, serrated grating.
In generally , the steel grating be used as stair tread, platform, fence, trench cover, ceiling, etc.
The advantage of steel grating :
firm welding
smooth surface
high strength
