Foliar fertilizer spraying of vegetables should vary according to the vegetables
⑴ Leafy vegetables. For example, cabbage, spinach, shepherd's purse, etc. require more nitrogen. Spraying fertilizer should be mainly urea and ammonium sulfate. The spraying concentration of urea should be 1~2%, and ammonium sulfate should be 1.5%. Spray 2~4 times per season, preferably in the early growth stage.

Use Triacontanol to soak seeds. Before the seeds germinate, soak the seeds with 1000 times solution of 0.1% triacontanol microemulsion for two days, then germinate and sow. For dryland crops, soak the seeds with 1000 times solution of 0.1% triacontanol microemulsion for half a day to a day before sowing. Soaking seeds with Triacontanol can enhance the germination trend and improve the germination ability of seeds.

The role of Triacontanol on crops. Triacontanol is a natural long-carbon chain plant growth regulator that can be absorbed by the stems and leaves of crops and has nine major functions.
① Promote energy storage and increase the accumulation of nutrients in crops.
② Triacontanol has a physiological function to regulate and improve the permeability of crop cells.

This type of foliar fertilizer contains substances that regulate plant growth, such as auxin, hormones and other ingredients. Its main function is to regulate plant growth and development. It is suitable for use in the early and middle stages of plant growth.
