Objective: The purpose of this project was to clarify shade condition's effect on the formation of kernel number per spike and analyze yield components of wheat under shade condition so as to take an effective growth measurement on fruit tree-crop intercropping models (Jujube-wheat, Apricot-wheat and Walnut-wheat intercropping). Method: In the present paper, the effects of shading on kernel number per spike were studied and analysis of yield components of wheat under the artificial shade condition was carried out. Result: The results showed that, under the artificial shade condition, the fertile florets, plant weight, grains per spike, grains weight per spike, spike number per hectare and yield were obviously reduced in the course of the wheat growth period. Conclusion: The results indicated that improving the kernel number per spike should be focused on the differentiation, growth and development, degeneration and grain courses of florets. Improving the yield should be focused on the growth and development, spike number per hectare and grain-filling characteristic courses of plants.
