The purpose of the work was to determine the effect of the post-harvest residue biomass of field pea, spring rye and their mixtures on mineral nitrogen content in the soil profile after the forecrop harvest, as well as the yield and quantity of nitrogen accumulated in winter triticale grain. An experiment was conducted to examine the following two factors: (I) forecrop – mixtures: field pea – pure stand 100%, spring rye – pure stand 100%, field pea 75% + spring rye 25%, field pea 50% + spring rye 50%, field pea 25% + spring rye 75%; (II) forecrop harvest date: field pea flowering stage, field pea green pod stage. The results revealed that the lowest mineral nitrogen content in after harvesting spring rye in the flat green pod phase in the soil layer 0–30 cm and 30–60 cm respectively 2.36 and 1.41 mg kg⁻¹ soil. Also, mineral nitrogen content was low in the 0–30 and 30–60 cm soil layers following field pea/spring rye mixtures, in particular the mixture containing 25 + 75% of the respective components. Winter triticale cultivation after field pea/spring rye mixtures harvested at the stage of field pea flat green pod contributes to high grain yield.

该工作的目的是确定豌豆，春黑麦及其混合物的收获后残留生物量对农作物收获后土壤剖面中矿质氮含量的影响，以及氮素的产量和累积量。小黑麦粒。进行了一项实验，以检查以下两个因素：（I）作物–混合物：豌豆–纯林分100％，春黑麦–纯林分100％，豌豆75％+春黑麦25％，豌豆50％+春季黑麦50％，豌豆25％+春黑麦75％; （二）前茬收获日期：豌豆开花期，豌豆绿荚期。结果表明，在土壤层0–30 cm和30–60 cm的平坦绿色荚果期中，收获黑麦后的最低矿质氮含量分别为2.36和1.41 mg kg ^-1泥。而且，在田间豌豆/春黑麦混合物之后，尤其是含有25 + 75％的相应成分的土壤中，0–30和30–60 cm土层中的矿物氮含量较低。在豌豆平生绿色荚果阶段收获豌豆/春季黑麦混合物后的冬季小黑麦栽培有助于提高谷物产量。
