How to manage autumn apricot trees? Apricot tree is the earliest fruit tree in spring flowering, and the first flower after the leaves, flower formation by the accumulation of nutrients required in the autumn of the previous year to complete, so good autumn management of the next spring flower structure and fruit set plays a decisive role. The autumn tube of apricot garden should grasp the following three items: First, thinning technique and short section. Apricot tree is a strong light-loving tree species, its growth is very vigorous, it is easy to form competitive growth and make the fruit part move outward, which is very unfavorable to the formation of strong flowers and fruits, so it should be in the autumn tube after fruit picking, the fruit tree should be mainly thinned, and the pruning method of pulling large branches and lowering tree height should be adopted to promote the lower part and inner bore to pull new branches, forming short fruit branches and bouquet fruit branches. Of course, while thinning, attention should be paid to ensuring that the main branches reserved are evenly distributed and open the light path, and pulling, dropping, distinguishing and supporting the branches that can be reserved and stand upright should be adopted to change the branch direction and make use of the space for more fruits; the skirt branches, weak branches and over-dense branches can be thinned together. 2. Fertilization and irrigation. In autumn, 50-100 kg of quick-acting nitrogen fertilizer or 30-50 kg of urea can be applied to each mu of apricot orchard, and appropriate amount of phosphorus and potassium fertilizer can be applied. For planting big trees, 3-5 kg of nitrogen, phosphorus and potassium fertilizer can be applied around the tree pit. It is good to meet rain after application. If summer drought and autumn drought are serious, irrigation can be done in August and September. However, it should be noted that the roots under the tree cannot be soaked for a long time, and it is easy to hurt the roots for a long time. 3. Insect control and leaf protection. Leaves are the factory of fruit tree nutrition, complete and thick leaves are the guarantee of apricot fruit, generally do not cause people's attention, hot summer combined with autumn drought occurs, easy to provoke red spider harm spread, or late autumn continuous rain, easy to cause deciduous disease, resulting in poor flower bud differentiation, can be timely sprayed with pesticides such as pyridaben or carbendazim, methylate to prevent diseases and insect pests, protect leaves. In addition, spraying 0.3% urea is more beneficial to the tree body. Click for more apricot planting techniques Click for more fruit planting techniques
