Spraying foliar fertilizers on grapes, leaves with a wide range of fertilizers, rapid fertilizer efficiency, and labor-saving fertilizers are common fertilization methods for grapes. To achieve the best results for foliar spray, you should master the following technical points:
Appropriate period of spray fertilizer:
In general, foliar fertilizers can be applied throughout the growing season of the grapes. It is best to spray the "tip-fertilizer" before the shoot growth, and to spray the "stabilized fruit fertilizer" during flowering and fruit setting; Application "strong fruit fertilizer." Spraying boron effect during flowering period is good; berry softening has a large role in the initial spraying of rare earth micro-fertilizers; appropriate amount of gold treasure fertiliser can be applied throughout the growing period, which can improve quality, increase yield and disease resistance.
Spraying weather and time:
Foliar spraying fertilizer, especially the golden beetle fertilizer, is greatly affected by wind, temperature, and humidity. Within a certain range, the higher the temperature, the faster the leaves suck fat; the higher the humidity, the more fertilizers are sucked in; the smaller the wind speed, the longer the moisturizing time of the fertilizer solution on the leaves, the more suction fat and the smaller the loss of drift. To improve the effect of spray fertilizer, it is best to choose a cloudy, cloudy, and sunny day. In sunny days, it should be performed in the morning or evening when the temperature is suitable (18°C-25°C), humidity is high, and evaporation is small.
Spray fertilizer method:
The stratum corneum of the grape leaves is thinner than the old leaves, and the penetration amount of the fertilizer liquid is large; the stomata on the back side of the leaf are more than the leaf front face and absorb quickly. Therefore, the application of grape leaf fertilizer should be based on young shoots, young leaves and the back of leaves. Fertilizer fertilizes the fine grain of the fog so as to make it evenly and densely. It sprays all the leaves wet, and the fertilizer drops without falling. According to the needs of a variety of fertilizers mixed spraying, but also with pesticides (including plant growth regulators) mixed spray and prevent pests.
