The nutritional functions of potassium on plants include: promoting the activation of enzymes in plants, enhancing photosynthesis, promoting sugar metabolism, promoting protein synthesis, enhancing the ability of plants to resist drought, cold, salt and alkali, resisting diseases and pests, etc. Meanwhile, potash fertilizer improves the quality of plant products. Also plays an important role.
The absorption of potassium by plants is also determined by the plant species. The order of potassium requirements is: sunflower, buckwheat, sugar beet, potato, corn> rapeseed, leguminous crops> cereal crops> pasture.
The main characteristics of plant potassium deficiency: the old leaves and leaf margins begin to yellow, and then turn brown, scorch burn like burning, brown spots or plaques appear on the leaves, but the middle leaves, veins remain green, with the degree of potassium deficiency Intensified, the entire leaf turns reddish-brown or dry and necrotic. However, the symptoms of potassium deficiency in different crops are also unique.
Potassium deficiency in cereals: brown spots appear on the lower leaves, and the same symptoms appear on new leaves. The leaves are covered with softness, the stems are weak, the internodes are short, the rate of spike formation is low, heading is uneven, and the seed setting rate is poor.
Brassicaceae, leguminous and cotton crops lack of potassium: leaf chlorosis between leaves, and then turn yellow, showing variegated leaves, severe leaf margin scorch down curl, brown spots along the veins between the inward development, but also epidermal tissue loss of water Shrinking, the foliar arches live concavely, gradually scorch and fall off, plant premature aging.
Loss of potassium in fruit trees: Yellowing of leaf margins, necrotic tissues gradually appear, and fruit is not sweet enough.
Due to the extravagant absorption of potassium by plants, excessive potash fertilizer wastes the amount of chemical fertilizers, inhibits the absorption of magnesium and calcium, and affects crop yield and quality.
Industrial steel structure buildings have a wide range of uses, and the high cost performance is worth choosing!
Industrial steel structure buildings are used in various industries, and their construction is convenient, and different steel structure buildings can be designed, which can also meet the needs of daily factories. Let's introduce the specific advantages of using steel structure buildings.
Wide range of uses
The scope of application of industrial steel structure buildings is still very wide. In addition to the use of factories as Steel Structure Workshop, some daily storage centers use Steel Structure Warehouse as warehouse, as well as gymnasiums, dormitories, etc., are actually buildings that can use steel structures. And not only the ground floor can be built, as long as the design is reasonable, then high-rise and multi-storey buildings can be constructed and applied.
Simple construction
Compared with traditional building construction, the construction of the steel structure itself is very simple, and all components are prefabricated and have certain standard sizes, which can be installed directly. The construction efficiency is high, and the construction of the plant can be completed in a short time. And generally it can be directly spliced, which greatly shortens the construction time, and the construction of large-scale buildings can be completed in less than one month.
High durability
Industrial steel structure buildings can be used for a long time, not just temporary use for a month or two, and the stability of the steel structure is also guaranteed. Moreover, the daily maintenance of the building is simple, and the design and construction of the building can be completed directly through computer design. Even if it is used in bad weather, there will be no problems, and it is suitable for long-term use.
beautiful and practical
Steel structure buildings come in many different colors, and manufacturers can also provide customized processing services. The design of the building is simple and beautiful, and it can also be decorated internally. Such a building has strong flexibility in use and can meet the requirements of different projects for long-term use.
Cost discount
Industrial steel structure buildings are light in weight, and the price of steel structures is favorable, and the cost performance is still good. Because of the high construction efficiency of its buildings, labor costs are also very cost-effective. It only needs to complete the design and construction, and the building can be put into use immediately, and the overall cost performance is also good.
