以先杂44高粱为试验材料,采用二因素裂区设计方法,比较不同施肥量、不同密度条件下对高粱产量、品质的影响,试验结果表明:施肥量相同,密度9.6万株·hm-2,产量相对较高(6 459.35 kg·hm-2);密度相同,施肥量750 kg·hm-2,产量相对较高(6 504.16 kg·hm-2)。肥密互作条件下,密度9.6万株·hm-2与施肥量750 kg·hm-2的栽培方式高粱产量相对较高(6 981.00 kg·hm-2),其单宁含量1.24%,蛋白含量9.28%,淀粉含量为65.53%,脂肪含量为3.64%,品质较好。试验表明密度9.6万株·hm-2与施肥量750 kg·hm-2的组合是杂交高粱先杂44较适宜的栽培方式。
The results showed that the yield and quality of sorghum were the same with different fertilization rates and different densities. The results showed that with the same amount of fertilizer and a density of 96000 plants · hm-2 The yield was relatively high (6 459.35 kg · hm-2). With the same density, the yield was 750 kg · hm-2 and the yield was relatively high (6 504.16 kg · hm-2). The yield of sorghum was higher (6 981.00 kg · hm-2) with the planting density of 96 000 hm-2 and the fertilizer of 750 kg · hm-2 under the condition of fertilizer and dense interaction. The content of tannin was 1.24% Content of 9.28%, starch content of 65.53%, fat content of 3.64%, better quality. The results showed that the combination of planting density 96000 hm-2 and fertilizer 750 kg hm-2 was the most suitable method for hybridization of sorghum.
