通过两年的盆栽试验,研究了有机物料对黑钙土的培肥作用。结果表明:用有机物料培肥土壤时,可以提高土壤有机质和重组有机质的含量,改善土壤的农化性质。提高有机无机复合量,降低原土复合度。追加复合量和追加复合度均随玉米秸秆施用量的增加而提高,但复合系数却因用量的增加而降低。施用有机物料还可以提高松结合态腐殖质的含量,改善重组有机质中腐殖质的结合形态。有机物料对黑钙土的培肥作用主要表现在第一年,医此可以认为每年向土壤中施入一定量未腐解的有机物料来不断地补充、更新与激活土壤中已渐老化的腐殖物质,是一项经济有效的培肥措施。
After two years of pot experiment, the effects of organic materials on the fertilization of Chernozem were studied. The results showed that when the soil was fertilized by organic materials, the content of soil organic matter and recombinant organic matter could be increased and the agrochemical properties of soil could be improved. Improve the organic and inorganic compound content, reduce the degree of original compound. Both the amount of additional compounding and additive compounding increased with the application of corn stover, but the compounding coefficient decreased due to the increased amount of corn stover. Application of organic materials can also increase the content of pine-bound humus and improve the binding form of humus in the recombinant organic matter. Organic fertilizer on the role of Chernozem Fertilizers mainly in the first year, the doctor can think that every year to the soil with a certain amount of non-decomposed organic materials to constantly replenish, update and activate the soil has been aging rot Colonies, is a cost-effective fertilization measures.
