Abstract

Abstract For seed germination and the formation of a good soybean crop, significant reserves of soil moisture are required, which depends on the autumn-winter soil preparation, weather conditions and planting dates. The purpose of this study is to identify the impact of the main tillage technology on its agrophysical properties and conditions for the growth and development of soybean plants. Experimental crop rotation: soybean – winter wheat was carried out under favourable (hydrothermal coefficient 1.46) and dry (hydrothermal coefficient 0.66–0.87) weather conditions. The main tillage was carried out with a stratifier PRSM-5 to a depth of 15–17 cm or a chisel plough PCh-2.5 to a depth of 25–27 cm, with additional pre-sowing or post-sowing rolling with a ring-spur roller KKSH. Sowing was carried out at a depth of 10 cm with stable heating of the soil in three periods: the first at 8–10 °С, the second at 10–12 °С, and the third at 12–14 °С. As a result of evaluating the influence of various factors, it was found that under favourable conditions, the highest seed productivity of soybean plants (1.91–1.96 t·ha−1) was formed after treatment with the stratifier PRSM-5 at the first sowing period and at the second sowing period after chisel ploughing with additional soil compaction. In dry weather conditions, pre-sowing treatment with a stratifier PRSM-5 had an advantage in seed productivity by 7–12% compared to ploughing with a chisel plough PCH-2.5.

不同天气下的农业技术措施和播种时间对大豆产量的影响
摘要为了种子发芽和形成良好的大豆作物,需要大量的土壤水分储备,这取决于秋冬土壤准备、天气条件和种植日期。本研究的目的是确定主要耕作技术对其农业物理特性和大豆植株生长发育条件的影响。轮作试验:大豆-冬小麦是在有利(水热系数1.46)和干燥(水热指数0.66–0.87)的天气条件下进行的。主耕采用分层犁PRSM-5进行,深度为15-17 cm,或采用凿式犁PCh-2.5进行,深度25–27 cm,并采用KKSH环形正齿滚筒进行额外的播前或播后滚动。播种深度为10 cm,土壤分三个阶段稳定加热:第一个阶段在8-10°С,第二个阶段在10-12°С,以及第三个阶段在12-14°С。通过评价各种因素的影响,发现在有利的条件下,在第一个播种期和第二个播种期,用分层剂PRSM-5处理后的大豆植株种子产量最高(1.91–1.96t·ha−1),并在凿犁和额外的土壤压实后。在干燥的天气条件下,与使用凿犁PCH-2.5进行犁耕相比,使用分层PRSM-5进行播种前处理在种子生产率方面具有7-12%的优势。
