对南疆杏麦复合系统3种主要复合种植模式中距杏树不同距离小麦的产量及其构成因素进行了研究与分析。结果表明,在南疆杏麦复合系统中,杏麦间作类型对小麦产量影响很大,三种主要杏麦复合种植模式中,宽幅复合种植模式(6 m×3 m6、m×4 m)对小麦产量的影响远小于窄幅复合种植模式(4 m×1.5 m)的影响。间作小麦与杏树的距离愈近,对小麦产量影响愈大,南北走向的复合种植模式,对间作麦区东边的影响远大于西边。不同复合种植模式对小麦产量构成因素的影响中,4 m×1.5 m复合种植模式对小麦穗数和千粒重的影响较大,对穗粒数影响较小;而6 m×3 m6、m×4 m两种复合种植模式对穗数和穗粒数影响最大,对千粒重的影响较小。
The yield and its components of wheat with different distance from apricot trees in three main planting patterns of apricot and wheat in southern Xinjiang were studied and analyzed. The results showed that the intercropping of apricot and wheat had a great effect on the yield of wheat in the apricot and wheat combination system in southern Xinjiang. Among the three main types of apricot combined cropping, the wide-composite planting mode (6 m × 3 m6 and m × 4 m) The effect on wheat yield is far less than that of the narrow-range compound cropping pattern (4 m × 1.5 m). The closer the distance between wheat and apricot trees, the greater the impact on wheat yield. The composite planting pattern of north and south directions has a far greater impact on the east side of intercropping wheat than on the west. The effect of different compound cropping patterns on the yield components of wheat was more significant than that of 4 m × 1.5 m composite cropping patterns, which had a significant effect on the spikes and 1000-grain weight of wheat, but had little effect on the grain number per spike. However, the effect of 6 m × 3 m6, m × 4 m two kinds of composite planting mode had the most influence on the number of spikes and grains per spike, but had little effect on 1000-grain weight.
