Fertilization of hydroponic flowers

1. Selection of fertilizers Hydroponic flowers need to be given special nutrient solution, which is generally not suitable for self-preparation. The soilless culture nutrient solution is prepared according to the nutrient ratio, concentration and acidity of the flower. In addition to the large amount of elements required by the plant, it also contains other trace elements. When using nutrient solution, the concentration of fertilization should be strictly controlled according to the requirements of the manual. Do not blindly apply it to avoid causing fat damage. The nutrient solution purchased should be placed in a dark place and at a low temperature, and should not be stored in a metal container. Different flowers have different requirements for fertilizer nutrients. Generally, the foliage plants should be based on nitrogen fertilizer, supplemented by phosphorus and potassium fertilizers. The flower-flowering plants, especially in their flower bud differentiation and flower bud development stage, should be mainly phosphorus and potassium fertilizers supplemented with nitrogen fertilizer.

2. Fertilization time Hydroponic flowers should be fertilized in spring and autumn with strong growth. Winter and summer are generally not suitable. If the flower is malnourished in summer and affects growth, a 0.1% urea solution can be applied to the foliage.

3. Fertilizing concentration When fertilizing, strictly control the concentration of fertilization, because all the nutrients applied are dissolved in water. When the concentration reaches a certain height, it will cause damage to the flowers, thus affecting the growth of flowers, and even lead to the whole plant. death. 1The concentration of different flower fertilization is not the same. The flowers such as scorpion scorpion, mini monstera, ruby, and sapphire are more resistant to fertilizer and fertilized. The roots are slender flowers such as Sihaibo, yarrow, and Begonia. The fertility of the genus and color-leaf grass is poor, and the fertilization should be lighter. 2 Hydroponic flowers should also be determined according to the strength of the plant growth potential. Generally speaking, the plants with strong growth potential are more resistant to fertility, and the fertilization can be relatively thicker, and vice versa. Indoor hydroponic flowers should stop fertilizing or reduce the concentration of fertilization in case of malnutrition, so as not to cause fat damage.

4. Treatment of Fertilizers If the branches and leaves of the flowers are weak and have no spirit after fertilization, the leaves are tarnished, and the roots are rotted and stinky, which is a characteristic of fat damage. Once the above situation occurs, the rotten root should be cut off in time, replaced with clear water and placed in the dark for maintenance, change the water once a day, and check the root of the flower, cut off the rotten root in time, until the new root is re-emerged, then transfer to normal Conservation.

Guide Shoe

The elevator guide shoe

Elevator guide shoe is a sliding part between elevator guide rail and car, what we call it guide shoe. It can fix the car on the guide rail and make car running up and down. Oil cup upper the elevator guide shoe that can reduce the friction of the shoe line and guide rail. There are four sets of guide shoes installed in each unit, respectively on both sides of the upper beam and under the safety clamp seat at the bottom of the car; and also four sets counter weight guide shoes are mounted on the bottom and top of the beam.

The guide shoes fixed on the car can move up and down along the fixed guide rail installed on the wall of the well way of the building to prevent the car from deviating or swinging in operation.

Guide shoe installation requirements

The installation method of guide shoe is to put it on the installation position of the guide rail of the car frame. After finding the right position, use the bolt fix it on the car guide rail frame. The installation must meet the following requirements:

1. When the upper and lower guide shoes are installed in the right position, they should be on the same vertical line. No slant or deflection is allowed. Both roller guide shoes and fixed guide shoes same requirement.
2. Fixed guide shoes are mainly used for FOVF units, the clearance between the two sides should be consistent, and the clearance between the inner lining and the rail top should be within O. 5 ~ 2 mm
3.
