醋糟、粉煤灰对盐渍地高粱生长及土壤性状影响的研究

以高粱生长情况和盐渍土改良作为切入点，研究醋糟、粉煤灰对盐渍地高粱生长及盐渍土的改良效果，为醋糟、粉煤灰盐渍土改良提供理论指导和技术依据。试验采用随机区组设计，分别设置纯醋糟（处理1）、醋糟与粉煤灰1∶1配比（处理2）、醋糟与粉煤灰2∶1配比（处理3）和对照4个处理。试验结果表明：高粱生长的4个时期，土壤速效养分含量均呈现先上升后下降的趋势，醋糟、粉煤灰处理效果好于对照，其中以醋糟和粉煤灰1∶1配比效果最好；对照处理土壤容重播种前后下降幅度最小，处理1、处理2、处理3土壤容重降幅分别为19.6%、28.6%、11.32%；处理1、处理2、处理3穗长分别比对照提高了6.25%、9.06%、3.93%；千粒重分别比对照提高了8.41%、9.26%、1.35%；单株产量分别比对照提高了10.53%、13.26%、8.89%；处理以醋糟、粉煤灰1∶1配比效果最好。综上所述，醋糟、粉煤灰改善了盐渍土理化性质，改善深层土壤的环境，为植物生长提供了适宜的生长环境，从而提高了高粱产量。

Effects of Vinegar Bad and Flyash on the Growth of Sorghum and the Improvement of Saline Soils

Based on the sorghum growth and salinity soil improvement, the effects of vinegar bad and flyash on the growth of sorghum and the improvement of saline soils were studied. The experiment was carried out with random block design, in 4 treatment, which were pure vinegar bad(treatment 1), vinegar bad and fly ash 1:1 ratio(treatment 2), vinegar bad and fly ash 2:1 ratio(treatment 3) and control respectively. The results showed that the contents of available nutrient in the four periods of sorghum growth increased firstly and then decreased, and the effect of vinegar bad and flyash treatment was better than that of control. Among them, the ratio 1:1 of vinegar and fly ash had the best effect. The results showed that compared with the control, the soil bulk density of treatment 1~3 was decreased by 19.6%, 28.6% and 11.32%, respectively. The spike length of treatment 1~3 was 6.25%, 9.06%, 3.93% higher than that of the control, respectively. The yield per plant of treatment 1~3 was increased by 10.53%, 13.26% and 8.89%, respectively. In summary, vinegar bad, flyash could improve the physical and chemical properties of saline soil, improve the environment of deep soil for plant growth, thereby increase the yield of sorghum.
