Ways to manage new vineyards in May

As the temperature rises, the growth of the grapes begins to accelerate. Since the nutrients stored in the tree in the early stage have been consumed for pumping, the nutrients are urgently needed to supplement the nutrients. Since the seedling roots after planting are small, the amount of nutrients used for absorption is also small. Therefore, it is necessary to diligently pursue less application, and apply urea 2 to 3 kg per acre, once every 15 to 20 days. Cut the seedlings to leave 1 vine. The vines are 1 meter high in batches, and the vines are tied in time. The secondary tips are erased in batches. Remove the tendrils. After topdressing, it is necessary to timely irrigate, loosen, and cultivate weeding.

The pests and diseases of vineyards cultivated in open field in May mainly include: downy mildew, gray mold, and winged moth. Downy mildew can be prevented by methyl thiophanate and Dasheng, and gray mold can be prevented by speeding with 1000 times of speed.
