摘要

的目标。在恢复С-СО - 2循环排放和吸收的规范参数的基础上,在乌克兰森林-草原现代气候系统条件下使用副产品作为有机肥,证实了在密集和有机施肥系统条件下短作物轮作的农业生态估计。方法。现场,统计,实验室。调查结果。短茬轮作的性能是由С-СО 2平衡能力决定的。强烈逆correla,被发现之间的能力N和C和N之间的比率agrocenosis,恶魔——stratocaster电吉他,增强humifi阳离子流程(比收缩)导致的增加的能力Сorg平衡和减少的能力水平С-СО2平衡(加强矿化),减少作物的性能相关的agrocenosis相比,轮作施肥的有机系统。С-СО 2和С org平衡容量在中等水平上呈反方向相关,主要产品产量、饲料单位和可消化蛋白产量在强直接相关水平上相关。结论。在农肥化和腐殖质阳离子化过程中,副产物和腐殖质的普遍矿化是拮抗作用,因此在高强度施肥系统中扩大С与N的比值刺激了性能的提高,而与有机肥系统类似,将С还原为N,由于С org与腐殖质结合,增强了腐殖质阳离子化过程,限制了矿化,导致了农肥化性能的降低。

Sequestration of carbon oxide in different fertilization systems in agrocenoses
Aim. To substantiate the agroecological estimation of the performance of a short crop rotation in conditions of intense and organic system of fertilization on the basis of restoring normative parameters of emission and se- questration of С-СО 2 circulation while using by-products as organic fertilizers in conditions of modern climatic system of the Forest-Steppe of Ukraine. Methods. Field, statistical, laboratory. Results of Investigations. The performance of short crop rotations is determined by the capacity of С-СО 2 balance. Strong inverse correla- tion was found between the capacity of N and the ratio between C and N in the agrocenosis, which demon- strated that enhancing the humifi cation processes (ratio constriction) led to the increase in the capacity of С org balance and the decrease in the capacity level of С-СО 2 balance (enhancing mineralization), related to the reduction in the performance of crops in the agrocenosis of a crop rotation compared to the organic system of fertilization. The capacity of С-СО 2 and С org balance correlates at the medium level of inverse direction, and the yield of the main products, feed units and digestible protein correlates at the level of strong direct correlation. Conclusions. General mineralization of by-products and humus in the agrocenosis and humifi cation processes are antagonists, so extending the ratio between С and N at the intense fertilization system stimulates the in- crease in performance and reducing С to N similar to the organic fertilization system enhances the humifi cation process due to binding of С org into humus and limits mineralization which leads to the reduction in agrocenosis performance at the organic fertilization system.
