Liaohonghuai is a new scholar tree variety discovered and bred by Qiu Yanchang and other experts from the College of Agriculture, Liaocheng University (Tel: 0635-8238266) from natural populations of Chinese scholar tree (Sophora japonica). In July 2007, the variety passed the DUS substantive examination of new plant varieties organized by the Office for the Protection of New Varieties of Plants of the State Forestry Administration, and in October it was granted new plant variety rights, becoming another new Chinese scholar tree variety with independent intellectual property rights.

Excellent characteristics of the variety: the flowers of the common Chinese scholar tree are white or pale yellow, with very few other variations. The standard petal of the Liaohonghuai flower crown is light pink, and the wing petals and keel petals are violet-purple; the flowering period begins about 7 days earlier than that of the original Chinese scholar tree species, and the entire flowering period is about 14 days longer than that of the common Chinese scholar tree. Liaohonghuai has bright flower colors, dense blooms, and is novel and beautiful, with high ornamental value, and can be promoted and applied as a new variety for landscaping.

Propagation technique: The propagation technique of this variety is the same as that of the Chinese scholar tree, mainly using grafted seedling propagation, with the bark-insertion branch grafting method used in spring. After the Beginning of Autumn, the bud grafting method is used. The seed propagation method is: collect the fruit after autumn, soak in water and rub off the flesh, dry in the sun, store in bags, and sow in the following spring, using bed preparation and drilling; thin and finalize the seedlings in late May.

Suitable growing environment and cultivation techniques: The biological and ecological characteristics of Liaohonghuai are similar to those of the common Chinese scholar tree, and its requirements for climate and soil conditions are the same as those of the scholar tree. In China, it can be cultivated in all provinces and regions except Heilongjiang, Jilin, Tibet and other provinces and regions. The Chinese scholar tree is a sun-loving tree species, with a deep root system and strong sprouting ability; it is cold-tolerant and drought-tolerant; wind-resistant; pollution-resistant, tolerant of smoke and dust, and adaptable to urban environments; tolerant of poor soil; highly adaptable, fast-growing, tolerant of pruning, and with a high transplant survival rate. The Chinese scholar tree has a well-developed root system and prefers to grow in deep, moist, fertile, well-drained sandy loam; neutral soil, calcareous soil and slightly acidic soil are also acceptable, and it can also grow normally in mildly saline-alkaline soil, but in overly dry, barren and windy places it is difficult to grow into large timber, and in low-lying waterlogged areas it often loses its leaves and dies.

When planting, apply sufficient organic fertilizer; apply quick-acting fertilizer when buds break in spring; water promptly after fertilizing and during drought.

The main pests of Liaohonghuai are aphids and the Chinese scholar tree looper (Ascotis selenaria), so pay attention to pesticide use and timely control.
