1.Apply bio stimulants as base fertilizer

This method refers to applying bio stimulants to the soil before sowing or applying it near the seed during sowing. This method is suitable for crops with higher planting density.

This method is simple and easy, and the amount of bio stimulants applied is relatively uniform. But this method also has its drawbacks. For example, because the entire field is fully applied, the root system can only absorb the bio stimulants around the root system, and the bio stimulants utilization rate is relatively low.

2.Apply bio stimulants as top dressing

Top dressing refers to the supplement and supply of nutrients to crops during their growth period. For crops cultivated at high temperature, it is best to reduce the amount of base fertilizer and increase the amount of topdressing.

This method can ensure that crops will not grow poorly due to lack of nutrients during the growth period, but this method must be adjusted according to ground temperature, crops, etc., and it needs to be applied in advance to reserve enough time for nutrient release.

3.Apply bio stimulants as nutrient soil

Many of the vegetables, fruits and flowers grown in greenhouses will choose soilless cultivation. The bio stimulants is added to the soilless culture substrate, and solid bio stimulants is added to the substrate every certain period to maintain a continuous supply of organic nutrients, which reduces the number of times of watering the nutrient solution and reduces the production cost.
