Embodiment 1

[0018] The cutting method of willow chrysanthemum comprises the following steps: step a. preparation of cutting seedbed, including selection of cutting location, preparation of cutting seedbed, ratio of cutting substrate, filling and disinfection. Cutting location selection: choose the cutting field, the soil quality of the cutting field is sandy soil, the average altitude is between 300-400 meters, the annual average temperature is 15-18°C, the annual rainfall is 1000-1400ml, and there are deep drainage ditches around the cutting field , the depth is 35-40cm, which is convenient to drain the rainwater from the cutting field, and avoid the base of the cutting strips from being rotted by too much rain; the preparation of the cutting seedbed: the height of the seedbed is 12-15cm, the width is 1.2-1.5cm, and the distance between adjacent seedbeds is 30 ~40cm; Proportion of cutting substrate, padding and disinfection: river sand and decomposed sawdust are selected for substrate rat...

Abstract

The invention belongs to the field of asexual propagation technologies for plants, and particularly relates to a cutting method for Salix varega ta Franch. The cutting method for the Salix varega ta Franch includes steps of a, preparing cutting seedling beds, in other words, selecting cutting locations, preparing the cutting seedling beds, and proportioning, paving and disinfecting cutting matrixes; b, performing cutting on the Salix varega ta Franch in the seedling beds in a period from April to October; c, preparing for cutting, in other words, collecting cutting strips, processing the cutting strips and performing cutting on the cutting strips; d, managing water, temperature, illumination and fertilizers after cutting is completed. The cutting method has the advantages that owing to the cultivation mode, a large quantity of Salix varega ta Franch can be subjected to cutting, a success rate can reach 99%, and the problem that planting requirements of hydro-fluctuation belts in the Three Gorges of the Yangtze river cannot be met due to rare existing wild Salix varega ta Franch plants can be solved; the problem of water and soil loss of two banks of the Three Gorges of the Yangtze river can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of asexual reproduction of plants, and in particular relates to a cutting method of Willow amurica. Background technique [0002] After the completion of the Three Gorges Reservoir, according to its dispatching plan, it will form a submerged zone with a submerged depth of 0-30m, a submerged time lasting 5-6 months, and extreme conditions such as counter-seasonal submerged from late October to late April of the following year. , resulting in drastic changes in environmental parameters such as light, pressure, and oxygen content in this area. These changes will have a relatively large or even restrictive effect on photosynthesis, respiration, growth and development, reproduction and phenology of native plants, and most species will die out due to fitness selection. At the same time, the drawdown area is the transition zone between the aquatic ecosystem and the terrestrial ecosystem, and plays an irreplaceable...
