摘要:

本研究探讨了位于宁夏灌区的大豆玉米带状复合种植模式对玉米物质生产与分配的影响。试验涉及4种在当地示范种植的带状复合种植模式:大豆玉米S3:M2、S4:M2、S3:M4、S4:M4,对照为单作玉米(M)。玉米供试品种为‘先玉1225’,大豆供试品种为‘中黄30’,玉米种植密度8.25万株/hm2,大豆种植密度15万株/hm2。结果显示,相较于单作玉米,带状复合种植模式下,玉米成熟期单株干物质减少了7.9%~30.4%,S3:M4影响最小,S4:M2影响最大;成熟期干物质总量减少了4.3%~42.7%。成熟期雌穗干物质分配减少0.5%~40.5%,S3:M4影响最小,S4:M2影响最大。玉米产量减产25.1%~41.4%,收获有效穗数减少4.2%~14.9%,千粒重减少0.5%~3.6%,单穗粒数减少5.2%~10.8%。综上所述,大豆玉米带状复合种植模式相较于单种玉米,雌穗的干物质减少,在吐丝期雌穗干物质积累开始减少,产量降低。这些发现对于优化大豆玉米带状复合种植模式在农业生产上的应用具有重要的实践意义。

Abstract:

To study the effect of banded composite planting pattern on maize material production and distribution in Ningxia irrigation area. This study explored the impact of the soybean-corn strip compound planting model located in the Ningxia irrigated area on the production and distribution of corn matter. Four kinds of strip composite planting patterns demonstrated and planted in Ningxia were selected for the experiment, soybean-corn S3:M2, S4:M2, S3:M4, S4:M4, with the control being monoculture corn (M). The maize test varieties was ‘Xianyu 1225’, the soybean varieties for test was ‘Zhonghuang 30’, the maize planting density was 82500 plants/hm2, and the soybean planting density was 150000 plants/hm2. The test results showed that compared with monoculture corn, the dry matter of corn planted in strip composite planting at maturity was reduced by 7.9%-30.4% per plant, with the smallest effect of S3:M4 and the largest effect of S4:M2; the total dry matter at maturity was reduced by 4.3%-42.7%. The dry matter allocation of female ears at maturity was reduced by 0.5% to 40.5%, with S3:M4 having the smallest effect and S4:M2 having the largest effect. Corn yield was reduced by 25.1% to 41.4%, the number of ears harvested decreased by 4.2% to 14.9%, thousand kernel weights decreased by 0.5% to 3.6%, and the number of grains per ear decreased by 5.2% to 10.8%. Soybean-corn strip composite planting pattern had less dry matter in the female ears than corn alone, and the accumulation of dry matter in the female ears at the spatula stage began to decrease, and the yield was reduced.
