摘要: 为了研究高粱对盐渍土地的改良效应和盐渍土地上高粱秸秆离子的变化规律,在山西省清徐县盐渍土上和榆次区壤土上种植耐盐高粱‘晋甜杂3 号’和‘晋杂1401’,比较种植高粱前后0~20 cm土壤中的钠、钾、钙、镁、氯离子变化和收获期高粱秸秆中钠、钾、钙、镁离子变化。试验结果表明:在盐渍土壤上种植两个耐盐高粱品种,虽然秸秆产量下降,但是秸秆中离子含量保持稳定,可以在清徐盐渍土上正常生长;高粱在盐渍土壤上种植,0~20 cm土壤的电导率及已测的五种离子含量均减少,而且盐渍土的离子减少量显著高于在壤土。因此,盐渍土上种植高粱可以有效改良盐碱地,而且甜高粱秸秆产量还可以给农民增加经济效益。

Abstract: To study the soil improvement effect and stalk ion change rule of sorghum in saline soil, two salttolerance sorghum varieties‘Jintianza3’and‘Jinza1401’were planted in saline soil of Qingxu and loam of Yuci. Sodium, potassium, calcium, magnesium and chloride ion in 0-20 cm soil before and after sorghum planting and the change rule of sodium, potassium, calcium, magnesium in harvested sorghum stalk were studied. The results showed that the two varieties had declined stalk yield but stable ion content in saline soil, and they could grow normally in the saline soil in Qingxu. Soil electrical conductivity of 0-20 cm soil and the measured content of the five kinds of ions reduced when the sorghum was planted in saline soil, and the reduction amount in saline soil was significantly higher than that in loam. Therefore, planting sorghum in saline soil could effectively improve the saline-alkali land, and the stalk yield of sweet sorghum could also increase farmers’economic benefit.
