I. Characteristics

The tree is an evergreen shrub, about 3 meters high, with developed root system, drought tolerance and no barren, and mycorrhiza parasitism in the root system.

Strong giving ability, like neutral to slightly acidic soil. Pyracantha also likes light and warm climate. The lowest temperature is-16.9℃,

Can grow normally and overwinter safely. Pyracantha fortuneana has strong drought resistance, and all areas with annual precipitation above 550 mm are

Can grow and bear fruit normally.

Pyracantha fortuneana fruit is rich in organic acids, protein, amino acids, vitamins and various mineral elements, which can be eaten fresh.

It can also be processed into various drinks. Its fruit ripens in autumn, like a torch, and can be planted as a street tree or a courtyard. Its root bark, stem

Peels and fruits are rich in tannins, which can be used to extract tannins. The root of pyracantha fortuneana can be used as medicine, which is bitter in nature and has the effect of stopping diarrhea and resolving hard mass.

Removing blood stasis, promoting digestion and other effects, fruits, leaves, stems and skins also have similar effects. The leaves of pyracantha fortuneana can be used to make tea, which has the functions of clearing away heat and toxic materials and protecting health.

The thirst-quenching, astringent and antidiarrheal effects of body fluid.

Second, the method of reproduction.

1, seed propagation. The fruit of pyracantha fortuneana ripens in June of 5438+00, and can stay on the tree until February of the following year. Seeds are collected in February of 10- 12.

Suitable. Remove the pulp in time after harvest, and wash and dry the seeds for later use. It is better to sow pyracantha in autumn. Before sowing

The seeds were treated with gibberellin with a concentration of 0.2‰, and the length was 20-30 cm and the depth was 5 cm on the sorted seedbed.

Ditch, sowing ditch, cover 3 cm with soil.

2. Cutting propagation. Take 1-2-year-old branches, cut them into cuttings with the length of 12- 15 cm, and arrange them at the lower end.

A ditch with a depth of more than 10 cm is opened on the rice transplanter, and the cuttings are placed at the edge of the ditch at an oblique angle of 30 degrees, with a spacing of 10 cm, exposing the upper part.

2-5 cm away from the bed, the soil is solid. The cutting time can be from 1 1 month to March of the following year, and the survival rate is generally 90%.

Let's go

Third, planting trees.

Choose sandy loam soil with flat terrain and rich organic matter for the fruit forest, and dig a pit with a depth of 0.6-0.8m according to the row spacing of 2m× 2m.

Fill in the base fertilizer and topsoil, plant them in the pit, and pour enough water.

Fourth, tending management.

1, fertilization Apply base fertilizer 1 1- 1 time every February, and dig 4-6 radial fertilization ditches along the tree 80 cm away from the root neck.

30 cm, 3-5 kg organic fertilizer was applied to each pit, and urea 1 time was applied before flowering and during fruit setting, respectively, and the application rate per plant was 0.25 kg.

2. Irrigation. Irrigation 1 time before and after flowering and in early summer is beneficial to the growth and development of pyracantha fortunei, which is dry and cold in winter.

In the waiting area, water 1 times the winter water before entering the hibernation period.

3. Plastic surgery. In the natural state, pyracantha fortuneana has a messy and irregular crown.

The branches in the inner chamber are often slender, and the knot strength is poor due to insufficient illumination. In order to promote growth and fruit, they should be pruned. fire

Spines have strong branching ability, and most of the lateral branches are planted horizontally on the trunk. Pyracantha can be integrated into a tree trunk layered shape, 40 cm from the ground.

It is 1 floor with 3-4 main branches, the second floor is 30cm away from 1 floor and consists of 2-3 main branches, and the third floor is 30cm away from the second floor.

It consists of two main branches, with twigs inserted between layers.

Step 4 trim. Pyracantha fortuneana is easy to branch, but the continuous fruit is poor, which is only about 10% in natural state. Therefore, we should deal with fruit branches.

Pruning is carried out every year to make the perennial fruiting branches retract and promote the emergence of new shoots. Pyracantha fortuneana has strong flower forming ability and is suitable for over-propagated flowers.

Branches should be shortened to promote them to grow vegetative branches. More than half of inflorescences, too dense branches and too thin branches should be thinned manually or chemically before flowering.

Weak branches, so that light can shine directly into the inner chamber, the annual pruning amount is subject to the amount of flowers, and the ratio of leaves to inflorescences is 70: 1.
