英文摘要	CONTEXT: To accelerate rural development, give play to regional advantages and improve economic benefits, the Chinese government has been promoting strongly the establishment of new agricultural operating entities, and adopting the planting of fruit-legume agroforestry system. However, the current popular planting pattern lacks comprehensive benefit evaluation from two aspects of yield and economy, and farmers lacks practical reference.OBJECTIVE: The purpose of this study was to investigate the planting status, agronomical and economic benefits of agroforestry in large-scale professional farming households, and to determine the optimal planting pattern in Xinjiang.METHODS: This experiment consists of field measurements and a questionnaire. (1) According to the common planting patterns in this region, the following five treatments were compared in Xinjiang: plumcot + soybean intercropping (PSI) (1.2 m interval between two species, soybean wide narrow row planting), plumcot + alfalfa intercropping (PAI) (1.0 m interval between two species, 0.15 m interval between alfalfa rows), sole-cropped soybean (SS) (soybean wide narrow row planting), sole-cropped alfalfa (SA) (0.15 m interval between alfalfa rows), and sole-cropped plumcot (SP) (5 m interval between plumcot rows). The underground interspecific competitiveness index, yield, land equivalent ratio (LER), Soluble solids content (SSC), fruit firmness and eco-nomic benefit were measured. (2) A two-stage stratified sampling procedure was applied. Eighteen fruit-legume large-scale professional farming households in each selected administrative unit were stratified into intercrop-ping with soybean or intercropping with alfalfa. The questionnaire survey investigated field management, sales channels, economic benefits and other information.RESULTS AND CONCLUSION: Large-scale professional farming households are scientific and market sensitive in developing agroforestry intercropping. Plumcot was consistently less competitive, and the main competitive area of the root system occurred at a depth of 0-0.2 m. The competition intensity of plumcot + alfalfa intercropping (PAI) was weaker than that of plumcot + soybean intercropping (PSI). Compared with sole-cropping, the yield of each species under intercropping decreased, especially that of alfalfa, but the land equivalent ratio increased. Plumcot intercropped with alfalfa had a higher soluble solids content. Intercropping has greater economic benefits, especially PAI. PAI was the most suitable planting pattern which can effectively solve the dilemma that fruit trees are not profitable in the juvenile growth stage of a plumcot.SIGNIFICANCE: An intercropping pattern can effectively solve the dilemma that fruit trees cannot make profits in the early stage of planting. There are few relevant research reports, and farmers lack decision-making suggestions on scientific planting and comprehensive economic benefits. Based on our findings, we suggest that large-scale professional farming households should develop the planting pattern of intercropping between fruit trees and legumes, especially new species of fruit trees and alfalfa. This will provide decision support for them to obtain benefits, improve land use efficiency and improve farmland ecology.
