I. Germination room and cultivation room
1. Selection of cultivation room: In winter, early spring and late autumn, plastic greenhouses, greenhouses and other facilities can be used to make use of the building or idle houses. When the average temperature is greater than 18 ° C, it can be produced on the ground and shaded by a shade net.
2, temperature: germination chamber temperature 20 ~ 25 ° C, relative humidity of about 90%; cultivation room temperature of more than 20 ° C during the day, no less than 16 ° C at night, to avoid large temperature differences. The relative humidity of the cultivation room is controlled at about 85%. Pay attention to proper ventilation in the room to maintain proper temperature and fresh air.
3. Illumination conditions: The germination chamber should be kept in a dark or weak light state. The cultivation room should have a blackout facility under the conditions of strong summer and autumn light. Those who use the room as the production room are required to face the south and extend the east and west (the width of the north and south should be less than 20m). The surrounding area is lighted, and the window area accounts for more than 30% of the perimeter wall. In the winter low light season, the light intensity of the near-south wall lighting area is not less than 5000 lux, the near-north window lighting area is not less than 1000 lux, and the central area is not less than 200 lux.
4. Water source: It has tap water, storage tank or spare water tank. The floor should be waterproof and leakproof, and a drainage system should be provided.
5. Auxiliary: including seed storage, seeding operation area, plug cleaning area, product processing area and other facilities.
Second, the cultivation rack
The three-dimensional cultivation has 4 to 6 layers, the first layer is not less than 10cm from the ground, and the layer spacing is 40-50cm. Each two racks are placed in one row, and the row spacing is 50-80cm, which is convenient for operation.
Third, the cultivation container
The vegetable seedling tray is made of 60cm x 24cm.
Fourth, the cultivation substrate
Use materials that are clean, light, non-toxic, water-absorbent, and easy to handle after use, such as paper, white cotton, non-woven fabric, perlite, foam plastic sheet, etc. 2.5 Spray system knapsack sprayer.
The conductive Pipette Tips are specially designed for automatic workstations and are made of medical grade conductive polypropylene (PP) material, and the tips are conductive. After the conductive tip is adapted to a specific automatic pipetting workstation, it can detect the liquid level, making the automatic sample addition more intelligent and precise.
Transparent automatic Pipette tips can also be called robotic pipette tips or micro tips; Yongyue Medical's pipette tips have been sterilized and are packaged with 96 pieces per box, which is easy to carry and operation; compatible for Beckman, Tecan, Rainin to achieve automatic pipetting performance and ensure the consistency of pipetting.
The robotic tip is made of imported polypropylene (PP) material, with high transparency. The surface is treated with a special process and has super-hydrophobicity to ensure the accuracy of experimental data. The product is automatically produced in a 100,000-level purification workshop, free of DNase, RNase, and pyrogen-free.
