Abstract

Abstract:

To study the effects of different application methods and concentrations of silicon fertilizer on the quality of plum ‘Qingcui’, plum ‘Qingcui’ was used as the test material, and silicon fertilizer was applied through root irrigation and foliar spraying. The results indicate that different application methods and concentrations of silicon fertilizer can significantly improve the appearance quality, such as single fruit weight, as well as the intrinsic quality indicators like soluble solids content, total sugar, total acid, and vitamin C in plum ‘Qingcui’. After flowering and during the fruit swelling period, spraying a 600-fold diluted solution of silicon fertilizer on the leaves is most effective. Irrigating the roots with 0.35 kg per plant before budding, after flowering, and during the fruit swelling period is the second most effective method. Foliar application can more directly provide the necessary silicon elements to the fruit, promoting its development and quality improvement.

Key words: silicon fertilizer, plum ‘Qingcui’, fertilization method, concentration, fruit quality
