Fertilization techniques for several vegetables

1. Leafy vegetables: Leafy vegetables mainly include cabbage, green vegetables, spinach, and leeks. Leaf-plant topdressing is mainly based on nitrogen fertilizer, but at the same time of application of nitrogen fertilizer, phosphorus and potassium fertilizers need to be added. For example, when cultivated Chinese cabbage, two fertilizations before entering the rosette period and before the core are the key to high yield. If the supply of nitrogen fertilizer is insufficient during the whole growth period, the plants are short and the tissues are coarse and hard, and the leafy vegetables cultivated in spring are easy to be convulsed early; if the phosphorus and potassium fertilizers are insufficient in the late stage, the ball is often difficult to form.
2, fruit and vegetables: fruit and vegetables include melons, solanes and beans, and edible parts are reproductive organs. Generally, the seedlings need more nitrogen fertilizer, but excessive application of nitrogen fertilizer is easy to cause long, but prolong the flowering result, leading to falling flowers and fruit; into the reproductive growth period, the amount of phosphate fertilizer needs to increase sharply, and the amount of nitrogen fertilizer needed to be slightly reduced. Therefore, phosphorus should be added. Potassium fertilizer, control the amount of nitrogen fertilizer. After the cucumber is placed on the melon, it should be re-fertilized. Each batch of melon should be supplemented with a fertilizer. 3, root vegetables: root vegetables mainly include radishes, carrots, etc., edible parts are fleshy roots. In the early stage of root vegetables, more nitrogen fertilizer should be applied to promote the formation of hypertrophic green leaves; in the middle and late growth stages (the fleshy root growth period), more potassium fertilizer should be applied, the amount of nitrogen fertilizer should be properly controlled, and the assimilation of leaves should be promoted to the roots to form a strong fleshy root. . If there is too much nitrogen fertilizer and insufficient potassium fertilizer in the late growth stage of root vegetables, it is easy to make the aboveground part grow, the rhizome is small, the yield is decreased, and the quality is deteriorated.

Safety Grating

Our safety grating create safer working conditions across a variety of industrial environments. Some of the industries that benefit from using our products in the construction of their walkways, ladders, stairs, ramps.

Stair treads metal grating offers a number of advantages. The material provides greater strength, reliability, and flexibility, qualities that make it well-suited for use in critical structures, such as stairs, ducting, roofing, and more.

Our safety grating provides a lightweight but durable surface that reduces the risk of slipping. It is suitable for use in many crane components, including the stairs, walkway, and operating platform.
The material offers durability and slip resistance-even when exposed to harsh road conditions, such as rain, snow, sleet, and dust-qualities that help ensure the safety of workers during loading and unloading operations.
Safety grating is used for many truck body components, including steps, flooring, and work platforms.

Features:
Corrosion resistance, Rust resistance.
Anti-slip resistance, Good air circulation.
Good drainage performance, Easy to install and uninstall.
High strength-to-weight performance,Durable and long lifespan.
