摘要

摘要向日葵是俄罗斯最有利可图的作物之一。研究是在两次10道作物轮作的多变量实验中进行的,并进行了长期稳定监测。研究了轮作方式和施肥量对向日葵产量及其经济效益的影响。土壤为重黑色土壤,腐殖质含量低,可在3.90–4.05层耕作 %. 研究发现,在向日葵下引入N20P30是合适的,并且具有成本效益,并且在提供足够的土壤流动磷酸盐的情况下,可以在40 千克/公顷。

Economic Efficiency and Bioenergetic Assessment of Predecessors and Fertilizer Systems in the Sunflower Cultivation
Abstract Sunflower is one of the most profitable crops in Russia. Research was carried out in a multivariate experiment in two 10-course crop rotations with long stationary monitoring. The influence of the crop rotation type and fertilizer doses on sunflower yield and its economic efficiency were studied. The soil is heavy black soil with low humus content arable in layer – 3.90–4.05 %. It was found that it is appropriate and cost-effectively to introduce N20P30 under a sunflower, and with sufficient provision of soil mobile phosphates it is possible to apply some nitrogen fertilizer at 40 kg per ha.
