It is good to spray urea before the leaves of the fruit trees

The nutrients required for spring germination, flowering, fruit set and shoot growth of fruit trees are mainly supplied by nutrients stored in the trees in the autumn of the previous year. After harvesting apples, pears and other fruit trees, spraying a certain concentration of urea solution on the foliage will have a good effect on increasing nutrient accumulation in the tree. Many years of practice have proved that after the fruit is harvested, high concentration of urea is sprayed, and the new shoots grow vigorously in the spring of the fruit trees. The short-leaved leaves are strong, the leaves are good, the flowers are neat, and the fruit setting rate is higher. The concentration of urea sprayed on the foliage is generally 3% to 5%. The spraying time is from the end of October to mid-November, and the specific time is sprayed once every 15 days before the leaves of the fruit trees. The back of the leaf is mainly sprayed. It is better to spray on weak trees, old trees and large trees with many results.

Steel Structure Workshop

These points cannot be ignored in the construction of steel structure workshop
The cost of the steel structure factory building is low, and the construction efficiency is high. It only needs to complete the basic design, and the construction can be completed immediately, and the factory building can be put into use quickly. However, when building a factory, we still have to pay special attention to the following points.

simple design
Different from other buildings, the steel structure factory building should still have a simple shape, generally designed as a rectangle, so that it is more convenient to use later and can also ensure the internal space. The layout can be carried out according to the terrain of the site, and attention must be paid to the specific design location of the workshop and whether there is a certain functional area division. Generally, the terrain slope of the factory building should not be greater than 5%, and the hilly slope should not be greater than 40%. Therefore, the construction should be carried out according to the local conditions, and the slope should be reasonable.

Construction location confirmation
As far as possible, the factory building should avoid locations such as earthquake faults, especially some locations prone to mudslides and landslides are not suitable for building factory buildings. If it is a valuable mining area, ancient tomb, etc., try not to build factories, etc. Before the construction of the factory building, it is necessary to do a good on-site inspection. If the local area is not suitable for the construction of the factory building, try to choose another place, so as to avoid the need to relocate the factory building later, which will be more troublesome and waste time and construction costs.

Reserved land for expansion
Steel structure workshops are very easy to expand, because with the increase in later construction requirements, many workshops may need to be expanded. Therefore, at the beginning of construction, a place for expansion should be reserved. At least the process requirements, transportation requirements, and whether there are other plant constructions should be considered.

Pay attention to construction inspection Steel Structure Workshop and Steel Structure Warehouse are relatively easy to construct and construct, so it is still necessary to pay attention to the need for safety personnel to inspect the site, and report in time if there are some installation problems. Moreover, after the construction is completed, there must be a construction inspection, and the stability of the plant must be ensured, so as not to affect the later use of the plant.

It is only necessary to select the appropriate materials for the construction of the steel structure factory building, and choose a suitable construction location, then basically the construction of the factory building can be completed immediately, and the factory building can also be quickly put into later use.
