Poinsettia is generally propagated by transplanting rice. When cutting, special attention should be paid to the change of environment. Intermittent spraying is used. Spray and shading are promptly applied after cutting to avoid direct sunlight. The initial lighting should be controlled at 10000 to 20000 Lx. After that, the light should be gradually strengthened to 20,000 Lx to 30000 Lx, and proper ventilation should be maintained. Before cuttings take root, the moisture content of the matrix should be kept between 60% and 70%, and the relative humidity of the air should be above 85%. Maintaining high air humidity is the key to successful cutting. The night temperature should not be lower than 21°C, and the daily temperature should not be higher than 28°C. You can use the method of controlling light intensity to help control the temperature. The survival rate of cuttings in the outdoors will be relatively low, and can be carried out in those greenhouses. At the same time, multiple temperature and humidity monitors are installed in the greenhouse to monitor the temperature and humidity changes in the environment. The measurement of light intensity can use photosynthetic efficiency. Radiometer to operate. If the survival rate of the poinsettia can be improved by directly using the seed germination box, he can directly control the temperature, humidity and light intensity.
After transplanting the poinsettia, the environment needs to be properly shaded, the light intensity is controlled at about 25,000 Lx, the temperature is controlled between 20° C. and 25° C., and the relative humidity is controlled between 60% and 70%. After successful transplantation, the required light intensity in the environment is 20 000 Lx to 60 000 Lx, and the optimal temperature range is 16°C to 29°C (26°C to 29°C during the day and 16°C to 21°C at night), and the relative The range of humidity is between 60% and 90%, and the temperature, humidity, and light intensity are properly adjusted according to the above instrument measurement.
Simplified Fine Nozzle Mould Baser
Simplify the design and application of the die holder for fine water mouth
1. Background introduction
The mold holder is a kind of mold widely used in the production of plastic products, whose main function is to provide the shape and size of the product. However, the design of traditional fine water die frame is complicated, the manufacturing is difficult, and the cost is high, which brings a certain burden to the enterprise. Therefore, it is of great significance to simplify the design and application of the fine water mouth die.
Second, design ideas
The design of simplified fine water die frame is mainly considered from the following aspects:
1. Composition structure: The simplified fine water die frame should be composed of standardized parts to reduce the difficulty and cost of customized processing.
2. Installation mode: The installation of the mold frame should be simple and fast, easy to operate, and reduce the input of human and material resources.
3. Versatility: Simplified fine water die frame should have a certain versatility, can adapt to the production needs of different products.
3. Application practice
The use of simplified fine mouth die holders can bring the following practical experience:
1. Use effect: The use effect of simplified fine water mouth mold frame is equivalent to that of traditional fine water mouth mold frame, which can meet the production needs of products.
2. Processing technology: Simplifying the processing process of the fine water die frame is relatively simple, reducing the difficulty and cost of manufacturing.
