The latest course on techniques and methods of flower and fruit thinning of red bayberry

The planting area of bayberry in China is still relatively large. Red bayberry is a very popular fruit, which can not only be eaten raw, but also can be made into a variety of non-staple foods, such as bayberry wine, dried bayberry and so on. When planting bayberry, we need to do a good job in management, in which thinning flowers and fruits can not be ignored. So how to thinning flowers and fruits? Let's take a look at it with the editor.

First, why should we sparse flowers and fruits

Bayberry is a kind of evergreen fruit tree, and evergreen fruit trees generally have the phenomenon of big and small years. Therefore, we should control the leaf-fruit ratio of bayberry trees, leave more fruit in strong trees and less fruit in weak trees, and thinning flowers and fruits according to the growth of branches. If the flower and fruit thinning of red bayberry is done properly, the fruit quality will be obviously enhanced, the ripening time is early and the rate of rotten fruit is low. Reasonable flower and fruit thinning can control the fruit amount of each bayberry tree, adjust the relationship between reproductive growth and vegetative growth, and achieve the goal of high yield and high quality year after year.

2. the method of thinning flowers and fruits.

1. The method of cutting short fruiting branches and thinning flowers

The method of cutting short fruiting branches and thinning flowers is a common method of flower and fruit thinning in bayberry trees. Usually in mid-February every year. To observe the growth of the big year tree, if the big year tree has more flower bud differentiation, then the fruit branches of the whole tree should be uniformly truncated 1 beat 5 or 2 beat 5 or so. Then, for some fruiting branches with weak growth and over-dense growth, they should be thinned out in time. And each tree should be properly topdressing urea and other available nitrogen fertilizer 1kg to promote the emergence of vegetative branches.

2. Chemical flower thinning

Chemical flower thinning is mainly aimed at big year trees and some plants with a large amount of fruit. After entering the full flowering stage, sparse 6 and other agents were used to thinning flowers. The amount of flower thinning can generally reach about 50%, and it can also expand the fruit shape, advance the fruit ripening time, improve the fruit quality and so on. And the number of new shoots and the output of the second year can also be significantly increased. For some trees with weak growth and some trees with more flower buds, some gibberellin can be properly sprayed after fruit harvest, about once every ten days, for about a month, which can increase the number of autumn shoots and inhibit the formation rate of flower buds.

3. Artificial fruit thinning

Artificial fruit thinning is the most effective method to reduce flower and fruit thinning and to prevent the phenomenon of big and small years. However, manual fruit thinning, the consumption of manpower is more, so it is not applicable to the scale of bayberry orchard. Artificial fruit thinning needs about 3 times, and it is the first time after the red bayberry enters the full flowering period, mainly dense fruit and small bad fruit. Then carry out the second time when the fruit grows to about the size of a ping-pong ball, leaving about one fruit on each fruiting branch. Finally, fruit thinning can also be carried out when the full flowering period is about one and a half months, with 3 fruits in the long fruit branches, 2 fruits in the middle fruit branches and one in the short fruit branches.

The above is a brief introduction to the technology of flower and fruit thinning of bayberry. That's all for today's introduction. This article is for reference only. I hope it can help you all.
