The number of suitable seedlings for tomato seedlings is 1~2 times, which is the most common one. The main reasons why tomato seedlings are not suitable for multiple seedlings are: Reduce the number of rooting because the more the number of seedlings, the more serious the damage to the root system, easily lead to premature root ageing. After avoiding the formation of too many times of aging seedlings, the root group will not be fully expanded and the absorption capacity will be weak, which will result in the seedlings being inhibited from growing due to insufficient nutrient supply. When the seedlings are inhibited for a long time, they will be inhibited. Formation of aging seedlings. To avoid prolonging the breeding period, it has been proved that tomato seedlings are produced once every minute, and the tomato seedlings of the same size are cultivated due to the hardening seedlings before the seedlings and the reasons for the slow seedlings after the seedlings are transplanted. The seedling propagation time is prolonged by 5 to 8 days in the environment. When the conditions are not suitable, the extension will take longer. Reduce other damage to tomato seedlings. Seedlings are vulnerable to starvation during seedling separation. Fragmentation during flower bud differentiation can have adverse effects on flower bud differentiation. We adopt a comprehensive classification method, which is divided by the ionicity of surfactants as follows which can all be provided by Insen Biotech: Surfactant Agent ,Carbomer 940 Powder,Surfactant Cosmetic ,Nonionic Surfactant Hunan Insen Biotech Co., Ltd , https://www.insenhealth.com
1. Anionic surfactant: stearic acid, sodium dodecylbenzene sulfonate.
2. Cationic surfactant: quaternary ammonium compound.
3. Zwitterionic surfactants: lecithin, amino acid type, betaine type.
4. Non-ionic surfactants: fatty acid glycerides, fatty acid sorbitan (Span), polysorbate (Tween).
