When is the oldest fruit tree in China ripe for picking? When is the best time to prune apricot trees?

Apricot is known as one of the oldest fruit trees, apricot trees are produced all over the country, most of them are cultivated, especially in North, Northwest and East China, and a few areas are wild. So when will apricots be ripe for picking? When is the best time for apricot pruning?

When will apricot be picked?

Apricot ripens in late summer and early autumn.

Apricot trees sprout and blossom in spring, the flowering period is generally between March and April, the flowering period is about half a month, and the time is concentrated, but the ripening of apricot fruit is greatly affected by temperature. the ripening period of apricot covers June to August, and most of them mature during wheat harvest in July. Apricot is ripe.

The harvesting method of apricot

The harvest time of apricot should be determined according to the use, consumption direction and transportation conditions. Generally speaking, the fruit used for selling or processing canned apricot and preserved apricot should be harvested when the fruit reaches the normal size and shape of this variety, has its inherent color and flavor, and the pulp still maintains a certain hardness, that is, medium well.

Apricot fruits used for fresh food should be harvested when fully ripe when they are sold in the local market. At this time, the appearance, size, quality, flavor and aroma of the fruit reach the best state, and the pulp changes from hard to soft, which is more welcomed by consumers; if the transportation conditions are slightly worse, or far away from the market, the harvest time should be slightly earlier.

Apricot fruits used for processing should be harvested according to the purpose of processing. Those who process dried apricot, apricot jam, candied fruit and fruit juice should be harvested when they are fully ripe but not overripe and softened; those used to make "green plum" and apricot "preserved plum" should be harvested when the fruit is not yet green. Apricots for kernel use should be harvested when the pulp is naturally cracked in order to make the almonds full.

When is the best time for apricot pruning?

Summer pruning of apricot trees is an important part of year-round pruning. Reasonable summer pruning plays an important role in the rapid prototyping of young trees and increasing the yield of primary fruit trees in the coming year.

The main results are as follows: 1. when young trees are pruning young trees in summer, the overgrown branches, competitive branches and upper dorsal branches should be heavily truncated or thinned. The extended branches of the main side branch and the central stem should be excised in late June to stimulate the germination of secondary branches to increase the grade and number of branches and buds, which can not only make the crown of apricot trees form early, ease the growth of branches, but also reduce the ineffective growth of branches. The ventilation and light transmission conditions of young trees can be improved by removing too many and too dense branches.

2. in the early fruit stage, apricot trees in the early fruit stage are mainly sparse branches or heavy pruning, thinning or heavy truncation, including competitive branches, upper dorsal branches and overgrown branches, reasonably remove overdense branches, improve ventilation and light transmission and prevent the growth of ineffective branches.

Third, old tree pruning, renewal and rejuvenation of old apricot trees, summer cutting is very important. For example, the number of new shoots sprouting on the big branches retracted in winter is large and the growth potential is strong in the coming year, the upper branches and overgrown branches should be removed or truncated in summer shearing, so as to reduce the growth of useless branches and increase the rapid growth of retained branches. The thinning of over-dense branches can cut short the main growing points where the growth is exuberant, induce secondary branches and increase the amount of branches and buds. Summer shearing should be carried out many times from June to August.

4. in order to keep the branches fully supplied with nutrition and remove the useless branches, the auxiliary shoots newly growing in spring should be cut in summer, which is generally carried out from June to August in our province.
