【摘要】 通过对新疆南疆核桃与小麦间作系统4种主要间作模式中的小麦进行测产,探讨了核桃树对小麦产量及产量形成因子的影响。结果表明,核(桃)麦间作模式对小麦产量影响很大。6m×12m、6m×9m对小麦产量的影响远小于3m×6m、3m×4.5m的影响。随着核桃树株行距的加大,开放度增加,小麦产量提高。间作小麦与核桃树的距离愈近,对小麦产量影响愈大,即距离核桃树越远,小麦的产量越高;距离桃树越近,小麦的产量越低。核(桃)麦间作模式下小麦产量变化的研究,为新疆南疆果农间作环境下小麦的高产栽培提供了理论依据。更多还原

【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.更多还原
