Betaine is a quaternary ammonium alkaloid widely found in plants such as beets and spinach. It has the functions of regulating osmotic pressure, promoting growth, and enhancing stress resistance, so it is widely used in agriculture.
- Main application areas
a. As a plant growth regulator
Promote growth: Betaine can stimulate plant cell division and accelerate growth, and is often used in crops such as vegetables and fruits.
Increase yield: By enhancing photosynthesis and nutrient absorption, betaine helps to increase crop yield.
b. Enhance stress resistance
Drought resistance: Betaine helps plants maintain cell water balance under drought conditions.
Salt-alkali resistance: In saline-alkali land, betaine can reduce the damage of salt to plants.
Cold resistance: Betaine enhances the survival ability of plants in low temperature environments by regulating osmotic pressure.
c. Improve quality
Improve taste: Betaine can increase the sugar content of fruits and vegetables and improve the taste.
Increase nutrition: Promote the synthesis of protein and vitamins, and improve the nutritional value of crops.
- Usage and dosage
a. Foliar spraying
Concentration: Usually use 100-500 mg/L betaine solution.
Frequency: Spray once every 7-10 days, 2-3 times in a row.
Time: Choose morning or evening, avoid high temperature periods.
b. Soil application
Dosage: Apply 1-2 kg of betaine per mu, mixed with fertilizer.
Method: Base application or topdressing, combined with irrigation.
c. Seed treatment
Concentration: Soak seeds in 50-100 mg/L betaine solution.
Time: Soak for 6-12 hours, dry and sow.
Through scientific and reasonable use methods and dosage control, betaine is expected to bring greater economic and ecological benefits to agricultural production. At the same time, glycine betaine, as one of the important forms of betaine, plays an important role in improving the stress resistance of crops and promoting growth and development.
