Edible apricot fruits are large, hypertrophic and juicy, moderately sweet and sour, and brightly colored. They are mainly used for raw food and can also be processed. There are more than 200 cultivated varieties in North and Northwest China. According to the color of the peel and pulp, it can be divided into three categories: varieties with yellow-white peel, such as Beijing Crystal Apricot and Hebei Daxiang White Apricot; Yellow peel, such as Gansu Golden Mother Apricot, Shandong Licheng Dayu Apricot, and Qingdao Shaoshan Red Apricot; and varieties with near-red peel, such as Hebei Guan Lao Face, Shanxi Yongji Red Plum Apricot, and Qing Xusha Golden Red Apricot. These are excellent edible varieties. Aging trees use dorsal branches with small middle and lower angles and strong growth to change their heads, or retract in relatively upright branches to promote the germination and renewal of hidden shoots. For well-positioned long branches, cultivate them as backbone branches and fruit branches. In accordance with the principle of “removing the weak and leaving the strong”, the strong branches and shoots are selected for renewal and pruning. If the tree is extremely weak and the renewal is difficult to work, on the premise of strengthening fertilizer management, the main lateral branches and large branch groups can be completely renewed in the 10-15 year. It is completed at one time. A large number of new branches can be germinated that year. Through summer sprouting, topping and winter plastic pruning, it can bloom and restore a certain yield the following year. When the new tip is about 15 cm long, quick-acting fertilizer is applied, and underground top dressing is alternated with foliar fertilizer spraying. Apply organic and compound fertilizers from the end of September to the beginning of October. After buckling the shed, urea is applied before germination, potassium sulfate compound fertilizer is applied after the flower is bloated, and urea and potassium dihydrogen phosphate are sprayed for 10-15 days. In addition, it can be sprayed 500 times to increase bacteria production at the same time. After planting, the seedlings are poured with permeable water. After that, depending on the specific situation, the amount of watering and watering time are determined during the apricot bud dew to expansion period, spray anti-stab sucking and chewing insecticides first, and then spray 4-5 pomedonite sulfide boiled by yourself plus 0.3% (mass fraction, the same) of sodium pentachlorophen. Spraying must be meticulous and thoughtful, so although there is a risk of damaging the flower buds, the effect of clearing the garden and disinfecting it is very good. Young trees with weak growth should be cut appropriately short, remove overdense and weak branches, retain more strong branches, and flatten upright branches as auxiliary branches to promote stout medium and short fruit branches. Trees during the fruiting period are appropriately densified and weakened according to the growth of the branches and the spatial conditions of various parts of the canopy to maintain stable results and growth. Weakened main branches, side branches, perennial auxiliary branches, fruit branches, and drooping branches are retracted in areas with strong branches to restore growth momentum. The lower canopy and inner bore branches are updated in a timely manner, so that fruit trees continue to produce new strong fruit branches. After the fruit is harvested, along with the continuation of summer pruning, routine tree management, disease and pest control work should continue as always, and should not be slack off. Protect the blades as much as possible, prolong the effective photosynthetic life of the blades, and prevent premature leaf fall. Since these tasks are general knowledge, they are easy to find on the Internet and in other sources, and will not be repeated here. The specific method is to leave 15-20 leaves on the nutritious branches of the new tip before picking fruit, and leave 3 to 5 leaves repeatedly for those who germinate later. After picking fruit, the hanging branches, cross branches, and overlapping branches are moderately retracted to make the canopy ventilated and transparent, but do not prune excessively during operation to prevent weakening the tree momentum or germinating too many new tips due to the stimulation of the cut. In short, summer pruning is an important auxiliary measure to effectively maintain the economic life of apricot trees02
