Description

Method for grafting prunus humilis on apricot tree stock in high position
Technical Field
The invention relates to a method for grafting Prunus humilis Bunge on an apricot tree stock at a high position, and belongs to the technical field of agriculture.
Background
Cerasus humilis (Bge) Sok) is small shrub of Rosaceae, Prunus, with average height of 0.5m, spherical, yellow, red or purple, diameter of 1.5cm, delicious taste, unique taste, and long shelf life, and Vc content in pulp is 590mg/kg, which is much higher than fruits such as apple, strawberry, grape, etc.; the content of Ca element reaches 500-900 mg/kg, and the Ca element has the highest content in various fruits, so the Ca element has the reputation of calcium fruit. The Prunus humilis Bunge kernel can be used as a medicine, and the traditional Chinese medicine is called as the "bunge cherry seed". The Prunus humilis Bunge fruit can be eaten fresh, and can be used for preparing series products such as preserved fruit, fruit juice, fruit wine and can, and can be used for extracting edible pigment. The Prunus humilis Bunge fruit has strong special fragrance, and can be processed into perfume.
Apricot (Armeniaca vulgaris Lam.) is a small deciduous tree of Prunus of Rosaceae, one of the most barren-resistant and most adaptable tree species in northern deciduous fruit trees in China, and has long cultivation history and wide planting area. Compared with most fruit tree species, the apricot tree has a deep and wide root system, and the thick cuticle of the leaves ensures that the apricot has strong drought resistance and strong cold resistance, and can resist low temperature below-30 ℃ in the dormancy stage.
Since the cerasus humilis is in a wild state for a long time, China starts an artificial introduction and cultivation test after 90 years of the last century. The existing cultivation mode is original cluster cultivation, branches and leaves are dense, ventilation and light transmission are poor, quality is poor, yield is low, and plant diseases and insect pests are serious.
