What problems should be paid attention to in tea cutting seedling management

Seedling propagation is generally divided into seed propagation, cutting propagation and grafting propagation. This paper mainly discusses the technical points of cutting propagation. Due to the different origins of seedlings and flowers, the requirements for environmental conditions in the process of cutting are slightly different. The temperature, humidity and requirements for light for cutting are described in detail below.

1. Temperature requirements for cuttage Usually, evergreen trees native to South China, such as camellia, rhododendron, osmanthus fragrans, Podocarpus, Ligustrum lucidum, Boxwood, jasmine, banyan, oleander, pittosporum, Michelia, etc. When cutting, high temperature is required, the temperature should be between 25~30℃ during the day and between 15 ~ at night. Deciduous trees and semi-deciduous trees, such as willow, poplar, pomegranate, crape myrtle, grape, etc. , native to the north, requires a low temperature, between 20~25℃ during the day and 15~20℃ at night. In the process of cutting, it is more important to control the soil temperature in seedbed than in greenhouse, especially for deciduous trees with hard branches in early spring. If the soil temperature is low and the greenhouse temperature is high, the upper leaf buds will grow fast, and the lower leaf buds will not take root or grow slowly, so cutting will be more difficult.
