| 【Objective】The study was carried out to find out suitable fertilization scheme for the planting of
Prunus persica‘apple’Peach in eastern Guizhou.【Method】Using the P. persica‘apple’peach orchards as research
objects, the effects of different fertilization including compound fertilizer, commercial organic fertilizer and colleseed oil
press cake fertilizer on soil nutrients and fruit aroma components were researched.【Result】In comparison with different
fertilizer treatments, applying organic fertilizers could improve the organic matter content, available P and available K
in soil, and the organic matter content was increased by 22.80% (the highest increase) under the treatment of colleseed
oil press cake fertilizer; the contents of available P and available K were the highest under commercial organic fertilizer treatment, which increased by 71.21% and 67.66%, respectively. Compared with compound fertilizer treatment, there was no
significant difference in soluble solid content, total acid, single fruit weight, longitudinal diameter and transverse diameter of P.
persica‘apple’Peach fruits under the organic fertilizer treatment, while the total sugar content and hardness of fruits under
the colleseed oil press cake fertilizer treatment were increased by17.26% and 17.16%, respectively. Compared with compound
fertilizer treatment, the application of organic fertilizer could increase the total aroma component content of fruits significantly,
under colleseed oil press cake fertilizer and commercial organic fertilizer treatments, contents of total aroma component were
increased by 44.07% and 22.82%, respectively.【Conclusion】The application of organic fertilizers can improve soil nutrient
effectiveness and aroma component of P. persica‘apple’Peach significantly, and the effect of colleseed oil press cake
fertilizer is better. |
