Hawthorn Introduction
As one of the most representative fruit trees of the Rosaceae family, the hawthorn tree has become an important species in the courtyard economy of both north and south China due to its unique morphological characteristics and wide adaptability. The fruit hanging on the branches, resembling red agates, are not only a visual delight but also carry rich medicinal value and ecological benefits.
Biological Characteristics of Hawthorn Trees
Family, Genus, and Morphological Features
Belonging to the Rosaceae family and hawthorn genus, the deciduous tree can reach a height of 6 meters. The leaves are triangular-ovate with pinnate lobes on the edges, and the compound corymbs bloom from May to June, consisting of 30-50 white flowers. In September, it bears dark red berries with a diameter of 1.4 centimeters.
Growth Adaptability
Adaptable to a wide range of soil pH values (5.5-8.0), it grows well in areas with annual precipitation of 400-800mm. The well-developed root system can penetrate 2 meters into the soil, tolerance to -35°C low temperatures in winter, and the leaf cuticle effectively reduces water evaporation.
Hawthorn Cultivation Technical System
Comparison of Propagation Methods
Grafting method can maintain good traits with a success rate of up to 85%, often using wild hawthorn as the rootstock. Seed sowing requires stratification treatment to break dormancy, and cutting uses semi-woody branches combined with root-promoting agents.
Water and Fertilizer Management Essentials
Water requirement during the germination period accounts for 25% of the annual amount, and 15kg of decomposed organic fertilizer is applied per tree during the fruit expansion period. Spraying 0.3% potassium dihydrogen phosphate on the leaves can increase the fruit-setting rate, and combined with drip irrigation technology, it saves 30% of water.
Comprehensive Application Value of Hawthorn

Medicinal Component Analysis
The fruit contains flavonoids 3.2-5.8mg/g, and the vitexin rhamnoside has a significant antihypertensive effect. The total acidity of fresh fruit reaches 4.5%, and processed products need to control the ratio of citric acid to malic acid.
