Planting apricot trees should be fertilized as early as possible after harvest
Apricot fruit ripens early, and there is still a considerable period of time from harvest to deciduous leaves. During this period, strengthening management plays an important role in reducing the occurrence of diseases and insect pests, promoting tree growth, restoring tree potential, and improving the quantity and quality of flower buds.
Apricot trees harvested after pest control are often harmed by diseases and insect pests. Timely spraying should be done according to the situation in order to protect leaves and increase tree nutrition accumulation.
Early fertilization should be applied after apricot fruit harvest, especially for the trees with weaker tree potential and more fruit in the same year, so as to make up for the lack of nutrients in the tree body. Ditches can be opened to apply organic fertilizer and a small amount of phosphorus and potassium fertilizer. Farm manure is the main organic fertilizer, generally, farm manure 3050 kg and calcium superphosphate 0.3 kg are applied to each fruiting tree at the beginning of 5 ~ 6 years, and 70 kg 100 kg and 0.5 kg superphosphate are applied to each tree at full fruit stage, and then watered immediately after application. In addition, 0.2% urea and 0.3% potassium dihydrogen phosphate were foliar sprayed for 3 times combined with spraying. This can improve the nutrition level of tree reserve, keep apricot trees strong after harvest, promote flower bud differentiation and ensure yield in the coming year.
After the apricot is harvested, the tree is still growing. It is necessary to control its vegetative growth, ease the tree potential and improve the internal light conditions of the tree. Because it is difficult to form full flower buds in the crown with poor light conditions, the methods of summer pruning (such as coring, twisting, pulling branches, other branches, opening angle, etc.) can be used to make the tree ventilated and transparent.
Because apricot trees are not resistant to waterlogging, if there is stagnant water in the rainy season, it should be eliminated in time to prevent apricot trees from being susceptible to waterlogging and affecting the growth and development of apricot trees.

Q: is it possible to pile up pig manure by digging roots during dormancy? Answer: from the biological characteristics of sugar orange trees, there is no relatively clear so-called dormancy period.

Apricot is the fruit tree which blooms earliest in spring, and blooms first and leaves later. The formation of flower depends on the accumulation of nutrients in the tree body in the autumn of the previous year. Therefore, good autumn management plays an important role in the structure of flower and fruit setting in the following spring. Autumn tube of apricot garden should
