Growing environment requirements and suitable cultivation conditions for Pinellia ternata
Pinellia ternata is a shallow-rooted plant that prefers fertile soil, and was originally mostly found growing wild on moist, loose, and fertile sandy loam or humus soil. It prefers a mild, humid climate and a shaded environment, is afraid of drought, and avoids high temperatures. In summer, it is best grown in a semi-shaded, semi-sunny environment; it grows relatively well when soil moisture content is 20%-40%; drought and water shortage easily cause the seedlings to fall over. Generally, with changes in the growing environment, it can fall over 1-3 times a year. For Pinellia ternata, falling over is, on the one hand, an adaptation to adverse conditions, and more importantly, it increases the number of bulbils, that is, it carries out one round of asexual

Key points of boxwood cutting propagation technology, suitable for northern regions
Boxwood is an evergreen tree species from the south, belonging to the Buxaceae family, genus Buxus. For many years, because of its many advantages such as low, compact growth, dense leaves, beautiful shape and evergreen foliage, it has been deeply loved by people and widely used in hedges and topiary design in landscaping. It is one of the tree species with the largest usage and the widest application in northern landscaping, but due to the influence of climate and other factors, raising seedlings in the north has always been relatively difficult. Greening seedlings in the north can only be transported over long distances from the south, which not only increases costs but also results in a low seedling survival rate. In response, we carefully summarized the experience
