Improved Cuttage Propagation of "Geranium"
In cuttage propagation of geraniums, because their stems are semi-succulent and contain a lot of water, rot often occurs and affects survival. For this reason, over the past few years the author has made certain improvements in combination with heavy pruning after flowering, so that when cuttings are taken at that time, the survival rate can be markedly increased. The specific method is as follows: select thick, strong branches on the plant, and from the top tip downward, at intervals of every 4 to 6 true leaves, or cut sections 7 to 10 cm long, until reaching the height of the usual heavy pruning of the plant after flowering, and plan in advance to divide them into several cuttings. Then, at a distance of

Biotechnology Assists Lily Variety Improvement
China is the natural distribution center of the genus Lilium. On this land, there are 47 species and 18 varieties of native lilies, which hold a very important position in the improvement of lily varieties worldwide. However, currently less than half of the original lily species are used in breeding, and there are still many original lily species with special superior traits that urgently need further development and utilization. Researchers at China's scientific research and teaching institutions have conducted a detailed analysis and study of the progress in lily variety improvement and biotechnology research in China. China's lilies have obvious advantages: Lilium dauricum, Lilium distichum, and others

Key Points of High-Yield Cultivation and Improved Techniques for Lilies
Lily yields are unstable; some plots suffer "disaster," with early seedling death and almost no yield. To achieve high yields in lily cultivation, focus on the "four improvements." 1. Replace poor-quality seed bulbs with high-quality seed bulbs. For lilies, select superior varieties such as Longya lily (Lilium brownii var. viridulum) as seed. The typical features of Longya lily are: bulbs tightly clasped, scales thick and fleshy at the lower part, pointed and curved at the upper part, shaped like dragon claws, colored like ivory. Leaves on the aerial stem are large and sparse, with no bulbils and no daughter bulbs. Lilies need to be purchased from other locations for seed, which is an important measure for rejuvenation. But pay attention to purchasing from sea
