There are various ways to raise vegetable seedlings. Seed tray seedling raising technology has become the main technology for large-scale chemical factory seedling raising due to its advanced nature and practicality. It is being widely used by producers and plays an irreplaceable role.
1. Save electricity, energy and materials
Compared with traditional seedling raising methods, using seed seedling trays can concentrate a large number of seedlings, and the amount of seedlings can be increased from 100 plants per square meter to 700~1000 plants per square meter (6 plug trays can be placed per square meter); Each plug seedling only needs about 50 grams (1 tael) of substrate, and each cubic meter (about 18 woven bags) of solid substrate can grow more than 40,000 vegetable seedlings, while plastic pot seedlings need 500~700 nutrient soil for each seedling. Gram (more than 0.5 kg); save more than 2/3 of electric energy. Significantly reduce the cost of seedlings and improve the efficiency of seedlings.
2. Improve seedling quality
One-time sowing, one-time seedling formation, the seedling root system is developed and closely adhered to the substrate, the root system will not be damaged during planting, it is easy to survive, the seedlings are slowed down quickly, and strong seedlings can be guaranteed. Plug seedlings retain more root hairs when transplanted. After transplanting, they can absorb a large amount of water and nutrients quickly. The growth of the seedlings will hardly be affected by transplantation. Generally, there is no obvious seedling slowing down period. The survival rate after transplantation is usually 100%.
3. Suitable for long-distance transportation, centralized seedling cultivation and decentralized supply
It can be packed in batches for long-distance transportation, which is conducive to intensive and large-scale seedling cultivation, and decentralized supply bases and farmers.
4. Mechanization and automation can be achieved
It can be accurately sowed by the seeder, sowing 700-1000 trays per hour (70,000-100,000 seedlings), which greatly improves the sowing efficiency. One hole per hole saves the amount of seeds and improves the utilization rate of seeds; transplanting seedlings can be carried out by transplanting machines, saving a lot of labor.
