To increase yields, it is necessary to improve the technologies for growing agricultural crops. Scientific research was carried out from 2016 to 2020. The optimal seeding rates per hectare, seasonal irrigation rates and doses of mineral nutrition were studied, this will reveal the levels of vegetable crop rotations adaptive intensification, its influence on soil indicators characterizing the soil formation evolutionary processes and the products quality. The objects of the study were onion hybrids of foreign selection Pandero F1, Benefit F1, Valero F1, Manas F1. The domestic zoned variety Volgodonets was taken as the standard one. As the result of the search for the optimal combination of moisture supply and mineral nutrition levels, it was established that for the Nizhneje Povolzhje region, in the conditions of the existing land use and the adopted soil preparation technologies, indicators that provide 80% of minimum water capacity are the optimal variant. For five years of observations (2016-2020) in the Astrakhan region, the Pandero F1 hybrid showed an average yield of 139.07 t/ha, Benefit F1 - 150.16 t/ha, Valero F1 - 123.73 t/ha, Manas F1 - 133.76 t/ha. In the Volgograd region, the same hybrids showed 103.10 t/ha; 129.57 t/ha; 111.6 t/ha; 104.09 t/ha, respectively. The research allows to recommend the production to include in the technological processes the soil basic preparation, namely autumn plowing, to plow not to 0.22 … 0.25 m by a conventional plow, but to plow without soil overturning by the Paraplau unit to the depth of 0.42 … 0.45 m. The authors offer to leave sowing by eight-row seeders and to change to sowing by a twelve-row seeder.

为了提高产量，有必要改进种植农作物的技术。科学研究于 2016 年至 2020 年进行。研究了每公顷最佳播种量、季节性灌溉量和矿质营养剂量，这将揭示蔬菜轮作适应性集约化水平，其对表征土壤形成进化的土壤指标的影响流程和产品质量。研究对象为国外选择Pandero F1、Benefit F1、Valero F1、Manas F1的洋葱杂交种。以国内划区品种Volgodonets为标准品种。作为寻找水分供应和矿物质营养水平的最佳组合的结果，确定对于下波沃尔日耶地区，在现有土地利用条件和采用的整地技术条件下，提供最低蓄水量80%的指标是最优变量。在阿斯特拉罕地区（2016-2020 年）的五年观察中，Pandero F1 杂交种的平均产量为 139.07 吨/公顷，Benefit F1 - 150.16 t/ha，Valero F1 - 123.73 t/ha，Manas F1 - 133.76 t /哈。在伏尔加格勒地区，同样的杂交种产量为 103.10 吨/公顷；129.57 吨/公顷；111.6吨/公顷；分别为 104.09 吨/公顷。该研究允许推荐生产在工艺过程中包括土壤基础准备，即秋季耕作，不使用传统犁犁至 0.22 … 0.25 m，而是通过 Paraplau 装置犁至不翻土至 0.42 深度… 0.45 米。
