Abstract:

In order to explore apricot wheat intercropping of wheat growth and yield of structural characteristics, wheat intercropping in apricot, apricot base point to the middle of two rows of apricot trees from near and far were divided into three areas (under the crown area, near crown area, crown zone far), we studied the wheat growth and yield of structural characteristics in three areas. Select ‘Xindong 20’ as material, the changes of wheat ears, dry matter accumulation, leaf area index, grain filling, yield components in apricot wheat intercropping were studied. The results showed that, tin wheat ears were faster than the intercropping system. In the intercropping system, the distance closer apricot, wheat and dry matter accumulation were lower the strength. Single-leaf area index for field was higher than the intercropping system. Single-filling rate was greater than the average for field intercropping system. Grains per spike and yield showed a single field for more than intercropping system, the highest one for field production, intercropping system for field average yield than the single-cut 49.72%. In the intercropping system, grain weight and spike number showed as far as the highest area > near crown area > under the district crown. Results indicated that, the apricot wheat intercropping system for wheat growth and development was not as a single field, resulting in lower wheat production in varying degrees.
