High-survival-rate photinia fraseri planting method

Abstract

The invention discloses a high-survival-rate photinia fraseri planting method. The photinia fraseri planting method particularly comprises the following steps that 1, soil which is loose and fertile and is from subacid to neutral is selected as a nursery, a nursery substrate is mixed in the soil, the ploughing depth of the soil and the nursery substrate ranges from 10 cm to 15 cm, insecticide is used for controlling soil insects, after ploughing is conducted, the soil is leveled, drainage ditches are made, and seedbeds are made, wherein the bed width ranges from 1 m to 1.5 m; 2, mature and complete photinia fraseri seeds are selected and soaked in a solution prepared from sugarcane juice, urea and cobalt chloride according to the weight ratio being 45:5:0.001 for 3-5 min, and after soakingis conducted, the seeds are taken out and naturally air dried till no water exists on the epidermis. The method has the advantages that the seeds are activated under stimulation of ingredients such as urea, plant ash, the urea and the seeds are mixed, the germination rate of the seeds is obviously increased, cultivation is conducted with the substrate, the germination rate of the seeds can be significantly increased, and the germination time is shortened.

Description

technical field [0001] The invention relates to the technical field of planting Photinia frondosa, in particular to a planting method of Photinia frondosa with a high survival rate. Background technique [0002] Photinia is a hybrid species of Photinia in the Rosaceae family. It is an evergreen small tree named for its bright red shoots and young leaves. As a precious evergreen color-leaved tree species, Photinia fragrans has the advantages of rapid growth, pruning resistance, compact plant shape, strong germination ability, and wide range of suitable growth. , cold-resistant and barren-resistant, it can be planted in most areas south of the Yellow River. The plant has strong resistance to poisonous gas and can be planted in areas with serious air pollution. [0003] It is widely used in gardens, and has good effects as hedges, green walls, modeling trees, and isolated plants. As a newly introduced and developed tree species, Photinia fragrans is still in the stage of seed...

Problems solved by technology

As a newly introduced and developed tree species, Photinia frondosa is still in the stage of seedling breeding in China, and only a small amount of seedlings are supplied to the market, which is far from meeting the needs of current nursery and garden engineering applications.

[0004] When Photinia fragrans is planted, hormone drugs are often used for seed germination and seedling cultivation. Hormone drugs cause pollution, the germination rate is often low, the survival rate after germination is also low, and the growth rate after planting is also slow.
