How can grape fruit be thinned quickly?
Farmers who have experience in planting grapes know that thinning flowers, fruits and ears can not only promote uniform grain size, good coloring, neat panicle shape and ripening, but also improve the quality of grapes. So, how do grapes thinner fruit quickly?
First, how to quickly thinning the fruit of grapes?
Generally, it is carried out immediately when the fruit is the size of soybeans and can tell the good from the bad, sooner rather than later. It is appropriate to leave 30-50 grains per ear to remove diseases and insect pests, malformed fruits with poor fertilization, small seedless fruits, top facing inward, and grains sandwiched in the middle of each ear.
Second, how to sparse the flowers of grapes?
The pinching time should be one week before flowering, and it should end when it comes to flowering. First pinch off the accessory ear, then pinch off 4-5 spindles on the main shaft, leaving 4-15 spindles, and then pinch off the spike tip. If the spike axis is too long, you should pinch it off. When there are more inflorescences, a fruiting branch leaves 1-2 inflorescences, and then pinches, which saves labor and effort and does not waste nutrients.
The purpose of inflorescence thinning is that there are many inflorescences of grapes, which can easily consume a lot of nutrients and reduce the rate of fruit setting. Pinching off the inflorescence tip can reduce the number of flowers, reduce the competition for nutrients and increase the fruit setting rate.
Third, how to thinning the ears of grapes?
When pinching the ear tip before flowering, the inflorescence should be thinned out a little more. The standard of thinning ear is that the golden mean branch with 11-12 leaves leaves 1 ear, and the strong branch with more than 21 leaves can leave 2 ears. Secondly, when the fruit setting condition has been seen clearly, the ear should be thinned as soon as possible, the ear with bad fruit setting should be removed as soon as possible, the ear on the very weak branch should be thinned according to the principle of one ear on one fruiting branch, and the ear should be selected according to the goal of high yield.
If you want to have a high and stable yield of grapes, it is more important to remove the fruits from too many grapes.
