不同盐碱地对甜高粱农艺性状的影响

[目的]探索甜高粱在盐胁迫条件下各农艺性状的变化动态.[方法]以2种甜高粱品种为材料,研究不同盐分含量对2种甜高粱农艺性状的影响.[结果]2品种耐盐能力存在着明显的差异.从不同盐分含量的试验地,2品种的出苗率、茎粗、株高和生物产量的变化情况来看,新高粱9号比新高粱3号具有比较强的耐盐能力.2品种在不同盐碱地含糖量差异不一致,新高粱3号含糖量高于新高粱9号.[结论]盐分含量对甜高粱各农艺性状都有影响.研究甜高粱耐盐能力对盐碱化地区甜高粱栽培与种植具有很大的意义.

Effect of Saline Soil on the Yield and Sugar Contents of Sweet Sorghum

【Objective and Method】The purpose of this program is to test the physiological change of sweet sorghum under the salinity conditions.The agricultural shapes of two sweet sorghum varieties were studied on the condition of different salt stress.【Result】The result showed that the saline tolerances of the two varieties of sweet sorghum were significantly different.According to the rate of seedling emergence,stem diameter,stem length and biomass,T601 is stronger than XT-2 in salt resistance.On the contrary,sugar contents in the stalks of the two sweet sorghum varieties were different with salt resistance.It was found that the sugar content in the stalks of XT-2 was higher than that in stalk of T601.【Conclusion】 The agricultural behaviors were affected by salinity condition,so one of the varieties of sweet sorghum should be selected for this purpose.
