摘要: 商麦156是商丘市农科所2015选育出的小麦新品种,为了探究商麦156的适宜种植模式,本试验以当地传统等行距种植为对照,研究宽窄行种植及播量对小麦生长发育及产量的影响。结果表明,随播量增加,植株株高、冠层20cm处PAR值增加,单株次生根、单株分蘖数、植株干重及冠层底部PAR值降低,播量越大,小麦亩穗数越多,穗粒数、千粒重越少,高播量(195kg/hm2)、中播量(150kg/hm2)处理下小麦产量差异不显著,但均显著高于低播量(120kg/hm2)处理;播量相同(150kg/hm2)的条件下,宽窄行处理能降低植株株高,增加植株单株次生根数、分蘖数、干重及冠层底部PAR比重,协调亩穗数、穗粒数、千粒重,增加小麦产量。总之,商麦156适宜在宽窄行条件下种植,适宜播种量为150kg/hm2-195kg/hm2。

Abstract: ‘Shangmai’156 is a new wheat variety selected and bred by Shangqiu Agricultural and Forestry Science Institute in 2015. To explore the suitable planting mode of‘Shangmai 156’, this experiment used the local traditional row spacing planting as the control to study the effect of row spacing and sowing amount on the growth and yield of wheat. The results showed that with the increase of seeding rate, the plant height and PAR value at 20 cm of canopy increased, the secondary root, tiller number, dry weight and PAR value at the bottom of canopy decreased, the larger the sowing amount, the more the number of panicles per hectare was, the less the number of grains per panicle and the 1000-grain weight were, and the difference in wheat yield under the treatment of high seeding rate (195 kg/hm2) and medium seeding rate (150 kg/hm2) was not significant, but both were significantly higher than that under the treatment of low seeding rate (120 kg/hm2); under the same seeding rate (150 kg/hm2), wide- narrow row treatment could reduce plant height, increase the number of secondary roots, tiller number, dry weight and PAR proportion at the bottom of the canopy, and coordinate the number of panicles per hectare, grain number per spike and 1000-grain weight, and increase the yield of wheat. In conclusion,‘Shangmai 156’is suitable for wide-narrow row planting, and the suitable seeding rate is 150-195 kg/hm2.
