1984～1986年对贵州东部地区各类低产田的酶系统特征、土壤酶活性的高低及其与土壤性质的关系进行了研究。结果表明:由于低产田类型不同,酶类型之间的组合及酶系统特征不同;低产稻田土壤的酶活性比经过改良的田块和高肥力田块低;不同土壤性态与各类型酶活性之间呈极显著或显著相关。因而酶活性反映了土壤的综合性态,反映了农作物对土壤环境的适应性,是土壤营养元素供应速率的体现。
From 1984 to 1986, the characteristics of enzyme system, the activity of soil enzyme and the relationship with the soil properties of various low-yielding fields in eastern Guizhou were studied. The results showed that the combination of enzymes and the characteristics of enzyme system were different due to the different types of low-yielding fields. The enzyme activities of low-yielding paddy soil were lower than that of the improved field and high-yielding plots. Different soil types and enzyme activities Between the significant or significant correlation. Therefore, enzyme activity reflects the comprehensive state of soil, reflecting the adaptability of crops to soil environment, which is the embodiment of nutrient supply rate in soil.
