Abstract:

Through the determination of wheat yield in the four most important intercropping patterns of south Xinjiang walnut-wheat intercropping system, we studied the effect of walnut trees on the wheat yield and yield components. The results indicated that, the walnut trees and wheat intercropping pattern affected prodigiously the wheat yield. Besides, in the four most important walnut-wheat intercropping patterns, 6 m×12 m and 6 m×9 m intercropping patterns affected the wheat yield less than 3 m×6 m and 3 m×4.5 m intercropping patterns. The wheat yield and openness increase with the increase of planting spacing. The closer the wheat apart from the walnut trees, the bigger the effect on the wheat yield components. On general, the farther from the walnut trees, the higher the wheat yield, and vice versa. Studies on the change of wheat yield in walnut-wheat intercropping conditions, in order to provide theoretical basis for high yield cultivation of wheat in south Xinjiang fruit crop intercropping pattern.
