The simpler the geographical conditions of the orchard, the easier the arrangement of fruit trees and varieties. On the contrary, the more complex the orchard's topography, the more difficult it is to configure the species. In principle, the tree species should be adapted to local conditions. At the same location, due to differences in topography, soil and microclimate, care should be taken to configure the appropriate tree species.
Generally, the pome fruit should be placed on a section with good fertilizer and water conditions, while walnuts, grapes, apricots, dates, etc., can be placed on the gravel and higher sections.
In order to extend the supply period in the mountains, the same kind of fruit trees can also be planted at different heights, so that the maturity can be first established to extend the market supply period. On the southern slope, it is usually possible to plant more rare stone fruits. It is more suitable to plant apricots and peaches in soils where the gravel layer is not deeply distributed. In areas prone to high winds, it is not suitable for planting pome fruit. Pears are cultivated in the sand wasteland, and grapes, apricots, sea buckthorn, etc. can be planted in the saline-alkali soil.
When configuring the types and varieties of fruit trees, the organizational and economic factors of the orchard should also be considered. In the same cell, it is preferable to configure a fruit tree because they have similar requirements for growth conditions in order to adopt the same management in one cell. When cultivating several varieties in the same orchard, it is best to select the varieties with the same maturity or maturity, so that the harvesting can be carried out simultaneously or sequentially, and the management is more convenient.
The orchard is also equipped with a pollination tree. Many fruit trees, such as pears, apples, and plums, have self-contained images, and even if they are self-sufficient, the result rate is low. Dioecious fruit trees must be placed in the orchard to be strong. Some fruit trees such as peaches and citrus are self-pollinated, but if they are cross-pollinated, the yield can be significantly improved.
Generally, the closer to the main varieties, the better the pollination effect. The distance between the pollinated tree species and the main varieties should not exceed 50-60 meters. There are many ways to configure. When the square is planted, the center type is commonly used, that is, eight major varieties are planted around a pollination variety. Pollination trees should be placed in large orchards and should be planted in rows and rows along the long side of the plot. The spacing of pollination trees should be 4-8 rows apart in the pits, and the stone fruits should be 3-7 rows apart. In the terraced land, you can plant a row of pollination varieties at intervals of 3-4 rows according to the direction of the terraces. Self-cultivating varieties, it is also appropriate to configure pollination varieties.
