| 摘要: |
| 针对兰州市秦王川引大灌区的次生盐渍化土壤地区耕地盐碱综合防治的研究目标，以菌糠和醋糟两种有机废弃物为材料，通过大田试验，系统分析了4种有机废弃物处理（菌糠7 500 kg·hm-2，JKⅠ；菌糠15 000 kg·hm-2，JKⅡ；醋糟7 500 kg·hm-2，CZⅠ；醋糟15 000 kg·hm-2，CZⅡ）对盐渍化土壤的容重、pH值、电导率以及小麦不同生育期叶片电导率和产量的影响。结果表明：醋糟对次生盐渍土壤的质地疏松、盐分抑制和修复改良效果总体上优于菌糠。施加有机废弃物耕种一季作物后，土壤容重下降6.45%～10.93%，土壤pH值下降0.59%～0.93%，土壤电导率下降36.84%～44.44%，且达到显著水平；有机废弃物对成熟期小麦叶片电导率影响最为明显，JKⅠ、JKⅡ、CZⅠ、CZⅡ4个处理分别显著低于CK 14.75%、16.76%、10.07%和20.14%；CZⅡ处理小麦产量最高，增产11.16%。 |

| Abstract: |
| The effects of four mushroom bran and vinegar residue treatments (mushroom bran 7 500 kg·hm-2 JKⅠ, mushroom bran 15 000 kg·hm-2 JKⅡ, vinegar residue 7 500 kg·hm-2 CZⅠ and vinegar residue 15 000 kg·hm-2 CZⅡ) on bulk density, pH value, and
electronic conductivity of soil as well as yields and conductivity of wheat in different growth periods was studied through a field experiment. The purpose of this study was to provide the theoretical basis for controlling soil secondary salinization in Qingwangchuan irrigation area, Lanzhou. The results indicated that vinegar residue was superior to mushroom bran of remediation on secondary salinization soil as a whole. Soil bulk density, pH value decreased by 6.45%～10.93% and 0.59%～0.93%, electronic conductivity decreased significantly by 36.84%～44.44% after a season of plowing with applying organic wastes. The effects of organic wastes to the mature period of wheat leaf conductivity was most obvious, compared with the CK, JKⅠ, JKⅡ, CZⅠ, and CZⅡ treatments which were significantly reduced by 14.75%, 16.76%, 10.07%, and 20.14% respectively. CZⅡ treatment had the highest wheat yield, which increased by 11.16%. |
