The latest management points of apricot trees in autumn

Autumn is not only the harvest time of fruit trees, but also the period of nutrition storage of fruit trees. the key to the management of apricot trees in autumn is to maintain the assimilation function of leaves, prevent early defoliation and improve cold resistance. Promote root growth and accelerate flower bud differentiation. So how to manage apricot trees in autumn? Come and have a look with the editor.

1. Soil, fertilizer and water management

First of all, base fertilizer should be applied in autumn, and before the Autumn Equinox, the amount of fertilizer should be determined according to tree age, tree potential, fruit and soil conditions. generally, 1-2 kg of fertilizer should be applied for every 1 kg of fruit, mainly rotten organic fertilizer. open half-ring ditches or radial ditches on the periphery of the crown. In addition, for apricot trees with weak growth and full fruit period, 0.2%-0.4% urea and 0.3% potassium dihydrogen phosphate foliar fertilizer can be sprayed once a month after harvest. When apricot trees enter the later stage of vegetative growth in autumn, reasonable irrigation is beneficial to nutrition accumulation and synthesis, as well as flower bud formation. in addition, attention should be paid to timely drainage and waterlogging prevention so as not to suffer from waterlogging and disease. Before the soil is frozen, autumn ploughing is needed, usually about 20 cm deep. When backfilling the soil, the topsoil is mixed with rotten leaves, weeds, dead branches or other farm manure.

2. Shaping and pruning

After the apricot harvest, pull the corners of the vigorous long branches to ease the tree potential, promote the formation of flowers, second coring for the new shoots, promote the branches, cultivate the branch group, retract the drooping branches properly, pick the cords in time for the overgrown branches in the crown, inhibit the vegetative growth during the period of vegetative growth, and remove the ungrown branches without room for growth in time. In addition, the dry and withered branches, cross branches, overlapping branches and weak branches in the crown should be cut off to improve the ventilation and light transmission conditions of the tree to facilitate the formation of high-quality flower buds. In the apricot fruit ripening to the harvest period, the tree angle should reach the best state, after harvest, the angle should have a stable period for a period of time, and the tree type can be fixed by means of top, pull, support and so on.

3. Pest control

Apricot trees are often harmed by diseases and insect pests in fruit picking, so according to the actual situation, timely spray control, for aphids can be used to control aphids; red spiders can use 1000 times liquid spray to control aphids. After harvest, methyl topiramate or carbendazim solution was sprayed every half a month to control bacterial perforation of apricot trees, and the leaves should be removed in time.
