How to promote the ripening of citrus autumn shoots

The autumn shoot of citrus is the fruiting mother branch, and the robust and neat autumn shoot is highly expected by every fruit grower. Good autumn shoot can not only reduce the phenomenon of customer service, but also ensure high and stable yield. But in the process of production, fruit growers often encounter the situation that citrus shoots are slow, irregular or even non-sprouting. So what is the reason why autumn shoots can't be put out? How to solve it? Let's take a look.

First, there is no reason why oranges can not be released in autumn.

1. Summer is a little immature, autumn germination is delayed.

Summer shoots grow vigorously, easy to pull and grow, overlord branches appear, and summer shoots are old and slow, which will certainly affect the hair of autumn shoots.

2. Nutrition can't keep up with it.

The shoot and root are closely linked. Because of drought and stagnant water in the orchard, there will be poor soil consolidation and air permeability, resulting in weak tree growth, root growth hindered, resulting in shoot extraction difficulties. Improper use in fertilization is easy to cause fertilizer damage, the root system can not effectively absorb fertilizer, resulting in the emergence of autumn shoots. In addition, serious diseases and insect pests, weak tree potential, will also affect the autumn shoot hair, hanging too much fruit will lead to the phenomenon of more fruit and less leaves, will also lead to the autumn shoot can not come out.

Second, the promotion of science

1. Summer shoots are not ripe.

For this phenomenon, it is necessary to promote the maturity of summer shoots and autumn shoots in time by means of topping, twig, shortening, fertilization and so on. Peeling off the top is to remove the top of the moderate summer shoot to weaken the growth potential and speed up the maturity, while the mackerel branch is carried out in the vigorous summer, erasing from the base to the tip, so that the young leaves and terminal buds of the summer shoot fall off, which is beneficial to the autumn shoot. In a short time, the weak summer shoots were cut short or erased; fertilization for the treated unripe summer shoots, small fruit plants, can be properly sprayed foliar fertilizer to accelerate the aging of summer shoots.

2. The tree is weak and has a large amount of fruit.

For the plants with too many hanging fruits and serious damage to diseases and insect pests, we should find out the cause and control in time, remove too many fruits, and timely remove the fruits with low economic value, such as top fruit, deformed fruit, disease and insect fruit, weak small fruit and so on, so as to reduce the burden on the tree.

3. Summer scissors

The summer pruning time is generally carried out from June to July, and the pruning degree is determined according to the tree age, tree potential and the amount of fruit hanging in the current year. at the same time, the ineffective branches such as cross branches, weak branches, disease and insect branches and drooping branches can be cut off at the same time.
