Embodiment 1

[0029] A cultivation method for Photinia frondosa, comprising the steps of:

[0030] (1) Selection of spikes

[0031] First select annual branches from the mother tree to make cuttings, then cut the selected cuttings to a length of 3 cm, cut flat on the upper notch, and cut obliquely on the lower notch, and the leaf area at the top is 1 / 5 leaf;

[0032] (2) Preparation of slotting bed

[0033] First, the nursery is leveled, and then the ground is surrounded by 8 cm wide planks to form an 8 cm seedbed with a ditch width of 3 cm, and the bed is sterilized with a disinfectant, the disinfectant is 500 times potassium permanganate, dikesone or 800 times thiophanate-methyl;

[0034] (3) Set up the shade

[0035] Use wooden stakes and sunshade nets to build shade. The selection of sunshade nets depends on the temperature. When the temperature is lower than 32°C, use a net with a shading rate of 50%, and when the temperature is higher than 32°C, use a net with a shading rate of 70%...

Embodiment 2

[0047] A cultivation method for Photinia frondosa, comprising the steps of:

[0048] (1) Selection of spikes

[0049] First select annual branches from the mother tree as cuttings, then cut the selected cuttings to a length of 4 cm, cut flat at the upper notch, and cut obliquely at the lower notch, and the leaf area at the top is 3 / 10 leaves;

[0050] (2) Preparation of slotting bed

[0051] First, the nursery is leveled, and then the ground is surrounded by a 10cm wide plank to form a 10cm seedbed with a ditch width of 4cm, and the bed is sterilized with a disinfectant, which is 750 times potassium permanganate, dikesone or 900 times thiophanate-methyl;

[0052] (3) Set up the shade

[0053] Use wooden stakes and sunshade nets to build shade. The selection of sunshade nets depends on the temperature. When the temperature is lower than 32°C, use a net with a shading rate of 50%, and when the temperature is higher than 32°C, use a net with a shading rate of 70%;

Embodiment 3

[0065] A cultivation method for Photinia frondosa, comprising the steps of:

[0066] (1) Selection of spikes

[0067] First select annual branches from the mother tree as cuttings, then cut the selected cuttings to a length of 5 cm, cut flat at the upper notch, and obliquely at the lower notch, and the leaf area at the top is 1 / 2 leaf;

[0068] (2) Preparation of slotting bed

[0069] First, the nursery is leveled, and then the ground is surrounded by a 12cm wide plank to form a 12cm seedbed with a ditch width of 5cm, and the bed is sterilized with a disinfectant, which is 1000 times potassium permanganate, dikesone or 1000 times thiophanate-methyl;

[0070] (3) Set up the shade

[0071] Use wooden stakes and sunshade nets to build shade. The selection of sunshade nets depends on the temperature. When the temperature is lower than 32°C, use a net with a shading rate of 50%, and when the temperature is higher than 32°C, use a net with a shading rate of 70%;

Abstract

The invention discloses a photinia fraseri cultivation method. Due to matching of chemicals and determination of a preparation method, the problem that rooting is slow due to improper use of rooting agents can be reduced, thorough watering is conducted immediately after insertion, a carbendazim and thiram mixed solution is used for spraying leaf surfaces, and the survival rate of photinia fraseri can be increased after cuttage. Naphthylacetic acid irrigation is conducted after cuttage, and the problems that roots are few and rooting is slow can be solved. Nitrogen fertilizer is applied 5-7 days after cuttage during after-cuttage management, gibberellin and cytokinin are sprayed once, and the problem that germination is slow after cuttage can be solved. Disease and insect pest prevention is conducted, meanwhile pruning and pinching are conducted, the tree form can be kept, growth tendency is adjusted, pinching can promote branching, and trees are prevented from being disjointed or thin and high. Photinia fraseri cultivated through the cultivation method has the advantages of being high in survival rate and high in growth speed, and is huge in market potential and wide in prospect.

Description

technical field [0001] The invention belongs to the field of nursery stock cultivation, and more specifically, the invention relates to a cultivation method of Photinia fruticosa. Background technique [0002] Photinia is the collective name for the hybrid species of Photinia in the family Rosaceae. It is an evergreen small tree. It is named for its bright red shoots and leaves. It has high ornamental value. It was introduced into my country from the Netherlands in 1998. As a precious evergreen color-leaved tree species, Photinia fragrans has the characteristics of rapid growth, pruning resistance, compact plant shape, strong germination ability, and wide range of suitable growth; it is sunny and shade-tolerant, acid, salt, drought, and cold. It is resistant to barrenness and can be planted in most areas south of the Yellow River. Its new leaves are bright red in four seasons, and can maintain an extremely eye-catching bright red color all year round with pruning. It has a ...
