摘要:
宁夏地区盐碱地面积大,利用率低,限制了当地的土地资源利用,因此改良利用盐碱地显得尤为重要。在宁夏吴忠市进行田间试验,选取玉米秸秆(JG)、黄沙(HS)、粉煤灰(FM)作为隔离垫层(铺设于树坑底部60cm处,各垫层厚度均为15cm),测量并分析7、8、10月份土壤0-80cm土层中pH、EC的动态变化,10月份土壤全氮、磷、钾含量及9月份垂柳胸径(DBH)、树高、新梢长、冠幅的生长量。研究结果表明,从7月到10月,JG显著降低了40-80cm土层的pH(10月比7月减少了5.85%) ,HS、FM均降低了土壤pH,但是效果不显著。JG、HS、FM三种处理均显著降低了0-20cm土层电导率(EC)(10月比7月减少了65%、68.7%、60%),其中JG、HS还分别降低了60-80cm、40-80cm土层的EC。土壤中全氮和全磷含量最多的处理分别是JG和FM,分别比CK增加了8%、19.48%,其中JG显著增加了60-80cm土层中的全氮含量,FM显著增加了40-60cm土层中的全磷含量,HS对土壤养分含量没有影响。对垂柳生长指标进行主成分分析,结果显示JG得分最高,改良效果最好。综上表明,选择JG作为宁夏地区盐碱地改良的最佳方案。
Abstract:
Saline alkali land occupies large area in Ningxia, China. However, since the utilization rate of such land is low, the use of local land resources is also restricted. Therefore, it is important to improve the management measures of saline alkali land. The study site was located in Wuzhong, Ningxia province. And the corn stalk (JG), yellow sand (HS) and fly ash (FM) were applied as the isolation cushion (its thickness is 15cm, and it was laid at the bottom of the tree pits). The dynamic change of soil pH and electrical conductivity (EC) were measured and analyzed in July, August and October in 2016, while the data of soil total nitrogen, phosphorus and potassium content as well as the values of tree height, diameter at breast height (DBH), length of new branch and growth volume of crown were respectively measured in October and September. The results showed that, from July to October, JG significantly reduced the pH of soil in the 40-80cm layer (showed a decrease of 5.85% when compared with that in July), while such significant reduction of soil PH did not occurred in the areas treated with HS and FM. Moreover, the EC value of soil significantly decreased in all treatments in the 0-20cm layer (65% decrease in JG, 68.7% decrease in HS and 60% decrease in FM when compared with that in July); furthermore, JG also reduced the EC value in the 60-80cm layer, while HS also reduced the EC value in the 40-80cm layer. In addition, the richest contents of soil total nitrogen and phosphorus respectively occurred in the JG and FM treatments, which were 8% and 19.48% higher than that in the control group.JG treatment significantly increased the total nitrogen content in the 60-80cm layer, while FM treatment significantly increased the total phosphorus content in the 40-60cm layer; however, HS treatment did not show a significant effect on increasing soil nutrient content. Based on the principal component analysis (DBH, tree height, length of new branch and crown width) of growth factors of Salix babylonica, JG treatment performed best in soil improvement than the other two treatments. In summary, JG treatment is likely to be the best solution to improve saline alkali land in Ningxia.
