April grape management technology

Spring is the season for grape sprouting, leaf elongation, heading and flowering. How to strengthen spring grape management and improve grape yield and quality is a common concern of fruit farmers.

 

After winter pruning, the winter buds on the mother branches usually have 70 to 80% germination, and attention should be paid to staying buds. Too much buds, easy to waste nutrients, so that the tree is weak, not conducive to fruit set; but if the buds are too small, it is easy to promote the growth of branches and shoots, causing serious fall and fruit, so pay attention to the buds and shoots.

 

Maya: usually a result mother when a plurality of sprouting, every 15 to 20 cm leaving a bud, leaving every 2 to 5 Jieguomuzhi shoots, remaining erased from the base. When Maya, typically erased without spikes double bud shoots or buds weak, leaving only a 1 shoot buds. Of course, in order to ensure the yield, when the new shoots grow to 4 to 5 leaves, depending on whether the first coil has spikes, it is decided to stay, but this wastes more nutrients.

 

Fixing the vines: Before the flowering of the new shoots, leave 5 leaves above the flower spikes , and leave 8 leaves without the flowers . After the topping, a large number of secondary shoots will be germinated, leaving only the top 1 to 2 secondary tips and leaving 2 leaves repeatedly topping, and the remaining secondary tips are completely erased. At the same time, it is necessary to tie the vines according to the growth of the vines.

 

When the grapes start disease prevention germination 3-5 leaves, spraying every 7 to 10 days one time, especially after the rain but also to strengthen the protection of spraying, and pay attention to weeding: weeding and disease control. This period is mainly to prevent grape black pox, gray mold, rust and so on.
