What Are the Propagation Methods for Cacti? A Detailed Guide to Common Methods
When it comes to propagation, we must clearly distinguish between asexual propagation by cuttings or grafting and sexual propagation by seed. Through asexual propagation, plants with exactly the same genetic makeup as the parent can be obtained; the offspring is in fact a part separated from the parent.

Symptom Identification and Control Methods of Walnut Bacterial Blight
1. Distribution and Occurrence Characteristics Widely distributed in walnut-producing areas such as Hebei, Shandong, Shanxi, Liaoning, Henan, Jiangsu, Zhejiang, Sichuan, Yunnan, Shanxi, and Gansu, with severe incidence in some areas. Infection generally begins in mid-to-late May. The pathogenic bacteria overwinter in the lesions of diseased branch tips or in diseased buds. In the spring of the following year, the bacteria spread by wind and rain splashing onto leaves, fruits, and young branches, causing damage. The pathogen can infect floral organs, so pollen can also carry the bacteria, and insects are also vectors. The bacteria invade through stomata, lenticels, nectaries, and various wounds. Under conditions of sufficient humidity, temperatures within the range of 4-30°C can cause infection of leaves, and 5-27°C can cause infection of fruits. The incubation period varies in different parts: 5-34 days on fruits and 8-18 days on leaves.

Symptom Identification and Control Methods of Walnut Rot Disease
1. Distribution and occurrence characteristics. Also known as black water disease, it occurs in Henan, Shanxi, Shandong, Sichuan and other places. The pathogen overwinters in the diseased parts as mycelium or stroma and pycnidia. After the sap of the walnut tree begins to flow the following spring, when suitable conditions for disease development occur, conidia are produced,

A Detailed Guide to Walnut Drying and Dehydration Methods
1. Natural Sun-Drying and Dehydration After the walnut nuts are cleaned, they must not be exposed to direct sunlight, to avoid the shells splitting and the kernels spoiling. The washed nuts should first be dried in the shade on bamboo mats or sorghum stalk mats for half a day, and once most of the moisture has evaporated, they can be spread out on reed mats or bamboo mats to dry in the sun. Spread
