Root analysis system is a special instrument for measuring and analyzing plant roots. It can be used to determine the total root length density, root surface area, root projection area, root volume and root length density, root surface area, root projection area, and root volume. , It is an ideal system equipment to realize the analysis of plant roots and the non-destructive determination of roots. The scientific development of intercropping of apricot trees can effectively use land resources to achieve high yield, stable production, high quality and efficient production of agriculture.
Through the root analysis system, we can conclude that in the intercropping system, the roots of apricot trees are mainly composed of the absorption root (d2). The distributions of total root length density, root surface area, root projection area, root volume and root length density, root surface area, root projection area, and root volume in space are consistent in the spatial direction: horizontal distances, all along the distance from the trunk The increase decreases and in the vertical direction increases first and then decreases as the soil depth increases. In the intercropping system, the spatial distribution of the absorption roots of apricot tree increases with the age of the tree, horizontally to the middle of the roadway between the middle development, the vertical direction to the depth of the soil, and the spatial overlapping of the intercropping between the crops. The degree gradually increased. The overlapping area of ​​the 5a apricot tree and the intercropped roots was 20 to 60 cm from the trunk of 0 to 90 cm. The overlap between the colonized 10 a and the roots of the crops was 30 to 60 cm from the trunk of 0 to 200 cm. Within the layer range, the overlapping area of ​​the 15a planted apricot tree and the intercropped roots of the crop is in the range of 40-60 cm from the trunk to 0-230 cm. In the intercropping system, the spatial distribution of the root absorption of the apricot colonization of 10a planting increased with the decrease of row spacing of the apricot tree, horizontally to the middle of the intercropping roadway development, the vertical direction to the depth of the soil, the intercropping system The degree of interlace and overlap in space gradually increases. In the 6m×6m intercropping system, the overlapping area between the root absorption of the apricot and the absorption root of the intercropping is in the range of 30-60cm from the trunk about 0-80cm; in the 3m×4m intercropping system, the apricot tree absorbs the root and the root absorption of the crop. The overlapping area is within a range of 40-60 cm from the trunk about 0 to 110 cm.
Apricot tree is native to Xinjiang, China, and is one of the oldest cultivated fruit trees in China. It has been cultivated in many areas of China, and in order to further improve the quality of apricot cultivation and increase the yield of production, we use profile excavation and stratified sampling methods. Based on the measurements of root length, root surface area, root projected area, and root volume of apricot roots in an apricot intercropping system under oasis irrigation conditions using a root system, systematic analysis of apricot trees under different tree age and row spacing conditions was carried out. The spatial distribution of absorption roots and the spatial overlap between the roots of intercropping crops revealed the spatial and temporal pattern of water and fertilizer competition between apricot and intercropping plants.
