How does grape apply medium microelement fertilizer?

How does grape apply medium microelement fertilizer
Grape germination before: in order to promote new root germination, early germination, prevent early spring damage, early zinc, zinc oxide can be sprayed 1500 times solution.
From germination to new shoot growth: to promote vigorous growth of grape shoots and provide sufficient nutrients for flower bud differentiation, 1000 times solution of sodium octaborate or potassium octaborate can be sprayed, and 2-3 times solution of 2000-3000 times solution of iron chelate of EDTA/EDDHA can be sprayed to prevent iron deficiency and yellowing.
Bud period to before flowering: in order to promote grape bud robust development, promote normal pollination and fertilization, reduce falling buds and falling flowers, can be sprayed with sodium octaborate or potassium octaborate 1000 times solution, with spraying zinc oxide 1500 times solution.

Growth stage of berry: 1000-1500 times solution of calcium fertilizer with sugar alcohol chelate was sprayed.
