How does grape apply medium trace element fertilizer?

In the process of grape planting, medium and micro element fertilizer is often applied to achieve the goal of increasing production.How does grape apply medium trace element fertilizer?Here are some tips for applying micronutrients to grapes.
How does grape apply medium trace element fertilizer
Before grape germination: in order to promote the germination of new roots, early germination, prevention of early spring frostbite, early zinc supplement, zinc oxide solution can be sprayed 1500 times.
Bud to a new growth stage: to promote the healthy growth, grape new tip to provide sufficient nutrients for flower bud differentiation, spraying eight boric acid sodium or 1000 times eight boric acid potassium solution, and spraying EDTA/EDDHA chelating iron 2000-2-3 times, 3000 times solution to prevent iron deficiency yellows.
Bud period to flowering: to promote the healthy development grape buds, and promote the normal pollination, fertilization falls to reduce bud and the fallen petal, spraying eight boric acid sodium or eight boric acid potassium solution 1000 times, 1500 times with spraying zinc oxide solution.
Techniques for applying trace element fertilizer to grapes
After the fallen petal to grain formation: in order to reduce the grape physiological fruit drop, and increasing fruit-bearing rate, promote fruit enlargement, reduce the grain size, spraying zinc oxide 3000 times the solution, and cooperate with spraying sugar alcohol chelating calcium fertilizer solution 1000 times.
Berry growth: spraying sugar alcohol chelating calcium fertilizer, 1000-1500 times solution in grape berries) can promote the accumulation of sugar in the bagged fruit enlargement, and the skin color, prevent dehiscent fruit, improve the fruit hardness, prevent physiological deciduous;In the ripening stage of berries, it can promote fruit coloration, improve the rate of high quality fruit, prevent physiological yellow leaves, and prevent early deciduous leaves.15 days before grape harvest, increase fruit color and nutrient accumulation of tree body, and prolong fruit storage period after fruit harvest.
After harvest, apply autumn fertilizer: spray suspended zinc oxide solution 2000-3000 times, which can supplement the nutrition of grape tree body, restore tree potential, and lay a foundation for flower bud differentiation, flowering and fruit setting in the coming year.
The above is the introduction of the application techniques of micronutrient fertilizer in some grapes. The friends of grape growers can refer to the above fertilization methods and apply moderate and micro element fertilizer reasonably.
