Detailed Explanation of Key Techniques for Sowing and Raising Black Locust Seedlings in Mountainous Areas
Black locust (Robinia pseudoacacia) is one of the main tree species for afforestation and greening in mountainous areas. It is not only an important source of timber for mine props, railway sleepers, vehicles and boats, and farm tools, but also a good nectar plant. 1. Nursery site selection and land preparation. The seedling-raising site should be a sandy loam plot with flat terrain, good drainage, and deep, fertile soil, and should have irrigation conditions. After the seedling-raising site is selected, plowing should be carried out in autumn to a depth of 30 cm. In early spring, harrow finely and level while the soil is still frozen, and at the same time pick out grass roots and stones. In conjunction with land preparation, apply 3000-5000 kg of decomposed stable manure per mu.

Mountainous Bulb Propagation and Cultivation Techniques for Oriental Lilies
In recent years, both the cut flower production and consumption of lilies in China have grown rapidly, yet the bulbs still depend almost entirely on imports, and bulb self-sufficiency has become a "bottleneck" restricting China's lily cut flower production. Achieving domestic production of high-quality commercial lily bulbs is imperative. Zhejiang Province has diverse landform types, and the temperature differences at different altitudes are highly beneficial for bulb swelling and development and flower bud differentiation in bulbous flowers. Selecting cool mountainous areas in Zhejiang Province for cultivation, carrying out purification and rejuvenation and bulblet propagation of lilies, and solving the long-standing problem of China's inability to achieve self-sufficiency in lily bulbs,
