摘要:

为关中西部高粱高产栽培提供理论实践,以高粱品种‘红缨子'为试验材料,在大田试验条件下研究种植密度、锰肥、复合肥和锌肥不同组合对高粱叶片光合能力、籽粒品质、产量及构成因素的影响。获得高产的最佳组合方式是种植密度水平为3,锰肥、复合肥、锌肥水平分别为2;最优光合能力综合得分的组合方式是种植密度和锌肥水平分别为1,锰肥和复合肥的水平分别为2。不同因素组合方式对粗蛋白、淀粉、粗脂肪和单宁的含量均有一定的影响,且获得不同品质指标的最优组合方式存在差异。关中西部地区高粱种植密度16.5万株/hm2,配施锰肥7.5 kg/hm2、复合肥750 kg/hm2和锌肥7.5 kg/hm2可实现高粱产量和品质的双优。

Abstract:

To provide a theoretical practice for high-yield cultivation of sorghum in the western region of Guanzhong, the brewed sorghum variety ‘Hongyingzi' was used as the experimental material, and the effects of plant density, Mn-fertilizer, compound-fertilizer, and Zn-fertilizer in the field on the leaf photosynthetic capacity, seed quality, yield, and yield component were studied. The optimum compound mode of yield was to plant at a density of level 3, with Mn-fertilizer, compound-fertilizer, and Zn-fertilizer level of 2, respectively. The optimum compound mode for the comprehensive score of photosynthetic capacity was that planting density and Zn-fertilizer were level 1, and Mn-fertilizer, compound-fertilizer were level 2. The compound modes of different factors had a certain effect on crude protein, starch, crude fat and tannin, and there were differences in the different compound modes for obtaining different quality indicators. The compound mode with planting density of 16.5×104 plants/hm2, Mn-fertilizer of 7.5 kg/hm2, compound-fertilizer of 750 kg/hm2, and Zn-fertilizer of 7.5 kg/hm2 could obtain high yield and suitable quality in the western region of Guanzhong.
