摘要

调查于 2018-2021 年期间在保加利亚农业研究所（Kyustendil）的试验种植园进行，种植品种为李子（Prunus domestica L.）ʻStanleyʼ。种植于 2013 年。种植距离为 5x5 米。对以下施肥变量进行了研究：V1 - 未施肥（对照），V2 - 鸡粪 2.5 公斤/棵，V3 - 鸡粪 5.0 公斤/棵。从施用鸡粪 Vita 有机肥的第二年开始，施肥量与李子品种ʻStanleyʼ的树干生长率呈正相关。每棵树施用 2.5 公斤鸡粪可增加树冠体积，第三年增加了 56.56%，P<0.05，具有统计学意义。试验期间，平均每棵树施用 2.5 公斤鸡粪，产量增加了 79.16%，平均果重增加了 5.93%。两种施肥量下的果实干物质和酸含量都较高。

EFFECT OF CHICKEN MANURE FERTILIZATION ON VEGETATIVE AND REPRODUCTIVE PARAMETERS OF PLUM (PRUNUS DOMESTICA L.)

The investigation was conducted during the period 2018-2021 in an experimental plantation of the Institute of Agriculture – Kyustendil, Bulgaria with plum (Prunus domestica L.) cv. ʻStanleyʼ. The planting was created in 2013. Planting distances were 5x5 m. The following fertilization variants were investigated: V1 – unfertilized – (control), V2 – chicken manure 2.5 kg/tree, V3 – chicken manure 5.0 kg/tree. The correlation between the fertilizer rate and the trunk growth rate of the plum cv. ʻStanleyʼ was positive from the second year of chicken manure Vita organic application. The application of chicken manure at a rate of 2.5 kg/tree increased the canopy volume, and in the third year it was statistically significant at P<0.05 by 56.56%. On average for the period of the experiment, the fertilizer rate of 2.5 kg/tree increased the yield by 79.16%, and the average fruit weight by 5.93%. A higher content of dry matter and acids was found in the fruits at both fertilizer rates.

期刊介绍： FRUIT GROWING RESEARCH is an international journal, which has been issued under the care of the Research Institute for Fruit Growing Pitesti, Romania. Fruit growing research is an annual journal aimed at disseminating significant research and original papers on genetic resources, breeding of deciduous fruit trees species; fruit sustainable technologies – environment protection; propagation, virology and tissue culture, postharvest, that can be of interest to a wide audience of plant scientists in all areas of fruit growing. An international Editorial Board advises the journal.
