摘要

为了实现产量和土壤肥力之间的最佳平衡,这将有助于平衡农业生产的两个重要方面——作物高产和长期土壤肥力——有必要了解改变行距对蔬菜作物生长和土壤环境的影响。本研究旨在通过研究基辅地区的取食面积和种植密度来确定法老品种的适应特性,以获得高质量的chufa结节。主要研究方法是田间调查和分析荸荠形态性状和经济价值指标的变异。结果表明,不同的种植密度对茶树营养器官的发育有一定的影响,主要是由于在生长季节对资源的争夺。“法老”品种在疏生作物中表现出较高的地上块体形成强度,株密度为28 ~ 3.3万株/公顷,叶束数为145.2 ~ 147.4片,平均高度为50.4 ~ 52.3 cm。同时,随着植株密度的降低,根瘤的大小也随之增大,因为随着取食面积的增大,植株形成的叶束越粗,根瘤的力量越大。以60 × 60厘米的间距(2.8万株/公顷)排列的植株形成较大的根瘤,其最大尺寸为长3.1厘米,宽1.0厘米,厚1.2厘米。结果表明,“法老”品种在种植60×50和60×60厘米根瘤方案下具有较高的经济价值指标。当种植密度为28- 3.3万株/公顷时,新收获根瘤的高适销产量达到4.2-4.6吨/公顷。在60 × 60和60 × 50 cm株距下,干燥后根瘤平均产量最高,分别为3.35和2.99 t/ hm2,比对照分别提高20.9%和7.8%。在粮食安全和创收方面,Chufa是一种很有前途的作物,对植物种植的精确管理将有助于平衡产量和土壤肥力

Optimisation of the density of chufa (Cyperus esculentus L.) plants in the Kyiv region
To achieve the optimal compromise between yield and soil fertility that will help balance two important aspects of agricultural production – high crop yields and long-term soil fertility – it is necessary to understand the impact of changing row spacing on vegetable crop growth and the soil environment. The research aims to determine the adaptive properties of the Pharaoh variety by studying the feeding area and plant density to obtain high-quality chufa nodules in the Kyiv region. The main research methods were field studies and analysis of the variance of morphological traits and economically valuable indicators of chufa. It was found that different plant densities had an impact on the development of vegetative organs of chufa due to competition for resources during the growing season. The variety “Pharaoh” showed a high intensity of aboveground mass formation in sparse crops with a plant density in the range of 28-33 thousand plants per hectare, with the number of leaf bundles reaching 145.2-147.4 pieces, and their average height is 50.4-52.3 centimetres. At the same time, the size of the nodules increased with a lower plant density, since with a larger feeding area, plants formed more powerful ones with thicker leaf bundles. Plants arranged in a 60 × 60 cm spacing (28 thousand plants/ha) formed larger nodules with the largest dimensions: 3.1 cm in length, 1.0 cm in width, and 1.2 cm in thickness. It has been substantiated that chufa of the “Pharaoh” variety was characterised by higher economic and valuable indicators under the schemes of planting 60×50 and 60×60 cm nodules. The high marketable yield of freshly harvested nodules was formed at a plant density of 28-33 thousand units/ha and amounted to 4.2-4.6 t/ha. The highest average yield of nodules after drying was obtained under the plant spacing of 60 x 60 and 60 x 50 cm, which was 3.35 and 2.99 t/ha, which was 20.9 and 7.8% higher than the control, respectively. Chufa is a promising crop in terms of food security and income generation, and precise management of plant placement will help to balance yield and soil fertility
