摘  要：
为了解离树间距对枣麦间作小麦光合特性及产量的影响,分析了单作(D0)小麦及距离枣树90cm、110cm、130cm(D1、D2、D3)的间作小麦光合、LAI、分蘖及产量特点。结果表明,在灌浆期D0和D2、D3处理下小麦净光合速率比D1处理分别高13.04%、8.99%、11.73%,D0、D2和D3处理的小麦气孔导度比D1分别高21.43%、9.52%、16.67%,而各处理间蒸腾速率和胞间CO2浓度无明显差异。从拔节期至成熟期,不同处理间的小麦单株茎数、单株分蘖数、LAI和单株干物质积累量存在显著差异,表现为D0>D3>D2>D1。D0和D3处理下小麦穗数、穗粒数、千粒重均显著高于D2和D1;小麦产量表现为D0>D3>D2>D1,D0处理比D1、D2、D3处理分别高25.78%、16.49%和6.70%。枣麦间作下,距离枣树越远,小麦植株光合性状表现越好,产量也较高,因此优化枣麦株行距配置有利于小麦产量的增加。

摘  要：
In order to investigate the effect of distance from tree on photosynthetic characteristics and yield formation of wheat,four patterns,such as wheat(D0),and Jujube-wheat intercropping with different distance of 90 cm,110 cm,and 130 cm(D1,D2 and D3)were conducted.The photosynthetic characteristics,LAI,tillering characteristics and yield components of wheat were determined.The results indicated that the net photosynthetic rate(Pn)of D0,D2 and D3 treatments at filling stage was13.04%,8.99% and 11.73% higher than that of D1,and the stomatal conductance(Gs)of D0,D2 and D3 was 21.43%,9.52% and 16.67% higher than that of D1,respectively.There was no significant difference in transpiration rate and intercellular CO2 concentration among all treatments.From jointing stage to mature stage,there were significant differences in stem number per plant,tiller number per plant,LAI and dry matter accumulation per plant,with a rank of D0> D3> D2> D1.There were also significant differences in wheat yield and yield components among different treatments.The number of spikes,grains per spike and grain weight per panicle of D0 and D3 were significantly higher than those of D1 and D2.The yield of D0 was the highest,which was 25.78%,16.49%,6.70% higher thanthat of D1,D2,and D3 treatments,and the yield of wheat under different treatments ranked as D3>D2> D1.In the jujube-wheat intercropping system,the yield was increased with the increase of distance from jujube trees.Therefore,it is beneficial to improve the economic yield by optimal row spacing between wheat and jujube.
