Embodiment 1

[0049] Choose flat land or gentle slope land with sufficient sunlight, fertile soil, and convenient irrigation and drainage as the nursery for mother trees. The footpath of the nursery is 40cm wide, the border width is 1.2m, and the border length is 8m. Ditches are opened on the spot to drain, level and remove impurities, while applying sufficient base fertilizer. The ratio of base fertilizer raw materials used is 90% organic fertilizer, 7% decomposed cake fertilizer and 3% nitrogen, phosphorus and potassium fertilizer; the total amount of base fertilizer applied per mu is 800-1000kg. In mid-to-late October, a robust North American holly with a diameter of 2 to 5 cm without pests and diseases was collected as the ear-picking mother tree. The collected mother tree had bare roots without mud and retained most of the root system. Plant the mother seedlings on the day they are collected. The robust and disease-free North American holly with a ground diameter of> 5 cm is used as th...

Embodiment 2

[0054] Choose flat land with sufficient sunlight, fertile soil and convenient irrigation and drainage as the nursery for mother seedlings. The nursery is fully cultivated first, and the seedbed and the trail are divided. The trail is 40cm wide, the border is 1.5m wide, and the border is 8m long. Ditching is made on the spot to drain, leveling and removing impurities, and applying sufficient base fertilizer. The percentage ratio of base fertilizer raw materials used is: the total amount of base fertilizer applied per mu is 1000kg. From November to December, two-year-old sturdy North American holly with a ground diameter of more than 2cm and no pests and diseases was collected as the mother seedlings for ear-picking. The mother seedlings collected were bare roots without mud, and most of the root system was retained. Plant the mother seedlings on the day they are collected. First, soak and disinfect the roots of the mother seedlings with 0.5% carbendazim solution for 15-20 minut...

Abstract

The invention belongs to the technical field of plant asexual propagation, and relates to a North America holly tender branch cutting fast asexual propagation method. The method comprises the steps that North America holly is collected inside a garden to be adopted as a seed tree for artificial management, protection and cultivation, and scion wood is collected and subjected to cutting into a cutting bed with a cutting medium. The illumination, the relative temperature and humidity and the water content of the medium inside the cutting bed are controlled, on the condition that seed tree sources are quite limited, a large number of good North America holly cutting seedlings can be rapidly obtained, and a foundation is laid for promoting North America holly industrial development.

Description

Technical field [0001] The invention belongs to the technical field of plant asexual propagation, and relates to a method for asexual and rapid propagation of North American holly softwood cuttings. Background technique [0002] North American holly is an evergreen broad-leaved small tree of the Holly family, Holly, is a hybrid holly variety introduced from the United States by the Wuhan Forestry and Fruit Science Institute. It has a good tree shape, dense branches and leaves, long red fruit period, and good ornamental. It is suitable for gardens, solitary lawn planting, hedge planting and highway isolation belt greening, making bonsai, etc. It has a wide range of gardening uses. [0003] At present, it takes 1 to 2 years for the seedlings of North American holly to emerge, the germination rate is extremely low, and the seedlings grow slowly. Therefore, in order to protect and multiply the resources of this species and achieve sustainable development and utilization, explore a fas...
