Abstract

The results of studies on the effect of optimized fertilization ofpear plantations of the varieties Conferentsia and Osnovianska on morphological changes of the leaf apparatus and the yield of trees grown on dark gray podzolic heavy loamy soil in the Right-Bank Forest-steppe of Ukraine are considered. Under the optimization of mineral nutrition of these pear varieties in the unirrigated plantation, in different age periods of growth and fruiting, a significant increase in the total leaf area, each leafplate and its thickness was observed on the plots of optimized background with the additional introduction of N30 and N30K30. The highest yields of both research pear varieties in the period of fruiting and growth were also provided by additional nitrogen and nitrogen-potassium nutrition with appropriate fertilization on the optimized background. In these cases, there was a significant increase in tree yield compared to the unfertilized, and fertilized with annual application of N90P60K90, where there was a less balanced ratio of N:P:K in plant nutrition, although the total amount of fertilizer was greater. Key words: pear, fertilizer, variety, leaves, harvest, growth periods

优化施肥对重复栽培梨树叶面及产量的影响

考虑了乌克兰右岸森林草原深灰色灰化土重质壤土上梨品种Conferentsia和Osnovianska优化施肥对树木叶片器官形态变化和产量影响的研究结果。在对这些梨品种矿质营养进行优化的情况下，在优化背景的样地上，添加N30和N30K30，在生长和结实的不同年龄阶段，总叶面积、每片叶厚度和叶片厚度均显著增加。在优化的背景条件下，增施氮肥和适当的氮钾配施也能使两个梨品种在结实期和生育期的产量达到最高。在这些情况下，与未施肥和每年施用N90P60K90的情况相比，树木产量显著增加，其中植物营养N:P:K比例较不平衡，尽管肥料总量较大。关键词:梨，肥料，品种，叶片，收获，生育期
