摘要
为探讨河套地区麦后复种不同大豆品种的产量形成和品质特性,增加单位面积耕地的经济效益,促进当地农业种植模式调整,本试验用黑河35、黑河44、黑河49极早熟大豆品种进行麦后复种试验,设覆膜和未覆膜2种复种处理,大豆生长发育期内调查测定其主要产量相关性状和籽粒蛋白质含量。结果表明:同一大豆品种的相同时期覆膜种植的大豆株高、小花数、成荚率、单株籽粒干重、百粒重和产量都高于或显著高于未覆膜的。覆膜种植黑河49的株高、小花数最高,分别达40.87 cm和35.86个;覆膜种植黑河44的豆荚数最多、成荚率最高,分别达15.98荚和44.60%;覆膜黑河44的单株籽粒干重、百粒重和产量最高,分别达6.53 g、13.71 g和1 469.3 kg·hm^(-2),显著高于未覆膜种植的3个品种。麦后复种大豆的籽粒蛋白质含量显著低于春种大豆,且覆膜处理高于未覆膜。覆膜种植黑河44和黑河49较其它处理表现优良,是河套地区较好的麦后复种大豆品种。
In order to study the yield and quality characteristics of multiple cropping different soybean varieties after wheat in the Hetao area, increase economic benefit per unit area, promote the adjustment of cropping structure. In this experiment, Heihe 35, Heibe 44 and Heihe 49 were tested with multiple cropping, seted two kinds of plastic mulching and without film mulching processing, to investigate its soybean protein content and main traits on yields. The results showed that the same soybean varieties with mulching planting on plant height, flower number, podding rate, grain dry weight, 100-seed weight and yield were higher or significantly higher than no mulching in the same period. The height and floret number of Heihe 49 with mulching planting were highest, up to 40.87and 35.86 cm respectively. Mulching planting of Heihe 44 is highest in pod number and podding rate, up to 15.98 pods and 44.60% ; grain dry weight, 100-seed weight and yield was the highest of 6.53 g, 13.71 g and 1 469.3 kg·ha^ -1 and significantly higher than other 3 varieties without mulching planting. The grain protein content of soybean after wheat was significantly lower than sowed in spring, and mulching treatment was higher than no mulching. The results showed that the mulching planting of Heihe 44 and Heihe 49 were better than other treatments, suitable for growing in Hetan area multiple cropping after wheat.
