How to carry celery seedlings

Celery requires cold and humid environmental conditions, and has a certain degree of cold resistance, and its growth temperature is 15-20 °C. The seedling stage is more resistant to high temperature, and the seed begins to germinate at 4 °C. The optimum temperature is 15-20 °C, and the germination is slow under high temperature. At the same time, the germination of celery seeds requires more water and certain illumination.

Celery can be planted in batches throughout the year, depending on the region. For example, in Hangzhou, seedlings are planted in mid-June to August and late January to February. Among them, 1-2 months of seedlings, about 250 grams per mu, using film cover seedlings, seedling age 50-60 days; from mid-June to July, seedlings, about 0.5 kg per mu, using shade seedlings, seedlings Age 40-50 days; nursery in August, about 250 grams per mu, using shade seedlings, seedling age about 50 days.

Because the celery seed (actually fruit) is small, the peel is thick, the water permeability is poor, the emergence ability is weak, and the seed germination requires a lower temperature. Therefore, the seed needs to be properly treated before sowing to accelerate seed emergence. Generally, soak seeds for 12-14 hours, then rinse with water, wash them by hand, remove the epidermis, dry the surface of the seeds, and then germination at a temperature of 20-22 °C until 50% of the seeds are germinated. . Pour the bottom water before planting, and shade and rain during the hot season. After planting, about 7-14 days after emergence, the seedlings should be kept moist after the emergence of the seedlings. When the seedlings have 4-6 true leaves, they can be colonized. Due to the long emergence time of celery, weeds often appear in the seedbed, and the weeds should be removed when the seedlings have 1-2 true leaves. Linyi Fertilizer Network Copyright

Product Description

Grinding Glass Microsphere
1. To select glass beads in types, sizes and quantity in accordance with viscosity, rigidity and dispersal of the grinded materials. 
2. To clean glass beads and mill's inside before the grinding processed. 
3. To input the grinded materials firstly and a curtain amount of glass beads later. To add continuously glass beads till 70%~80% of the mill is full. 
4. To forbid to keep glass beads funning with little grinded material for a long time, as the glass beads inside the mill are easily broken at high speed operation. 

5. To add new glass beads to ensure the quality and efficiency of grinded materials. 

Grinding Glass Beads are mainly used for the disperser, grinding media of industries, such as coloring, paint, ink, coatings, resins, chemical engineering, with the advantages of smooth surface, even size, high hardness, good chemical stability. Thanks to the characteristics of heat-resistant, wearable, compression strength, the filling-type bead could be used to improve glass fibre reinforced plastic, rubber, and so on.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
