    摘要:

    耕作土壤是在各种自然因素以及人类生产劳动的影响下形成的。过去虽然认为每一种土壤都有着自己的发生与发展,土壤形成这一复杂的历史过程是在物理、化学和生物学因素的参与下完成的。可是在联系生产实际时,往往就简单地把土壤只看为不过是供应植物营养物质的仓库。这样孤立地片面地去了解土壤与植物之间的供求关系,是不可能解释土壤,特别是耕作土壤的实质的,因此也不可能正确地控制和创造更肥沃的土壤。

    Abstract:

    For understanding correlations between the high yield of soybean and the biochemical characteristics of the soils, field experiments were carried out with different fertilizer treatments. In one series of the plots both organic manure and chemical fertilizers were applied, while in the second series only organic manure was used. A third series without fertilizer treatment was taken as control. The biochemical activities of the soil were studied at different growing stages of soybean. Results of present experiments showed that there are definite correlations between the yield of soybean and the biochemical activities of the soil, including enzyme activities, respiration and rate of cellulose decomposition. Good correlations are also found between the yield of soybean and amount of free amino acids present in the soil. The origin of the enzyme activities and the active substances in the soil also show an intimate relationship with the soil microflora. Soil particles possess great absorptive power for the enzymes, other active substances, and soil microorganisms without any inhibition of their activities.
