Abstract

The article examines the influence of Osmocote Exact Standard fertilizers on the biometric parameters of Chinese plum (Prunus salicina) saplings of varieties Pyramidalnaya and Altayskaya Jubileinaya during vegetative propagation (by the method of winter grafting) in the Krasnoyarsk forest-steppe conditions. The use of prolonged fertilizers when growing plum planting material has a positive effect on the development of biometric parameters of the aboveground and underground phytomass of plants: the average number of shoots in the variant with longacting fertilizers was 2.7-3.0 pcs. An increase in the average length of shoots was recorded in the variants using Osmocote - 15.9-18.1 cm, these indicators are 2.9-8.7 cm higher than the control variants. Application of prolonged fertilizers had a favorable effect on the growth and development of the root system of plum seedlings: average the number of roots of the 1st branching order was 9.7-12.7 pcs, the average length of the roots of the 1st branching order was 9.4-10.3 pcs.

Highlights

In the gardens of Siberia, stone fruit crops are becoming more widespread [1; 2]
The aim of this work is to study the effect of Osmocote prolonged fertilizers on the biometric parameters of the Chinese plum
The objects of research were winter grafting of Chinese plum, which was carried out in laboratory conditions at a temperature of 18-20 ° C in March

Summary

Introduction

In the gardens of Siberia, stone fruit crops are becoming more widespread [1; 2]. Chinese plum is characterized by frost resistance, high potential yield, lack of periodicity of fruiting, nutritional value [3]. Special attention is paid to the quality of the used planting material. The time of the entry of the fruit plantation into the fruiting period, the rate of increase in yield, the payback of capital costs depend on the quality indicators of seedlings [4]. It is possible to grow one-year standard plum seedlings when using intensification elements, for example, using prolonged fertilizers [5; 6]. The aim of this work is to study the effect of Osmocote prolonged fertilizers on the biometric parameters of the Chinese plum
