Potassium dihydrogen phosphate foliar fertilizer can enhance the photosynthesis of fruit trees. Foliar topdressing can replenish the necessary phosphorus and potassium elements in the soil in a short period of time, which is better than the decline in soil quality caused by root covering soil topdressing.
Promote stem growth and development. Spring and summer are critical periods for the development of fruit tree branches and stems. Reasonable spraying of foliar fertilizers can promote root growth and enhance resistance to lodging, drought, cold and disease. .
Promote the flowering of fruit trees. Spraying one week before flowering can protect flowers and fruits and prevent flower drop, thereby achieving the purpose of increasing production.
Root dipping treatment. For fruit tree seedlings, taking an appropriate amount of solution to dip the roots can promote rapid growth and differentiation of the root system, improve the absorption capacity of soil nutrients, and prevent the invasion of soil pathogens.
