Application of drugs at flowering stage of grape to improve fruit setting
Gibberellin can be sprayed in the flowering stage of grapes. When the grapes are in full bloom, dipping in 25-40ug/g gibberellin solution in inflorescence or spray can increase the fruit setting rate and make the fruit mature 15 days earlier. Gibberellin is a kind of plant hormone, which can act on cotton, grape, vegetable, rice, wheat and other crops, can promote crop flowering and fruiting, improve seed setting rate, and play a significant yield-increasing effect.
In addition to medication, the first part of the inflorescence can be pinched off about a week before flowering, accounting for 1 / 2 of the length of the inflorescence. At the same time, the secondary inflorescence and the branches of the inflorescence and the second branch can be removed about 1 / 2, so that the inflorescence can form a short orchard column, which is beneficial to increase the fruit setting rate and fruit weight. Before the grape blossoms, 0.2% Mel 0.3% boric acid or 0.2% borax solution should be sprayed once every 5 days for 3 consecutive times to improve the quality of the flowers, promote the removal of caps and reduce the size of grains.
