What is the propagation method and cultivation technique of holly seedlings?

Planting techniques of holly trees :

Holly is suitable for planting in moist and semi-shady places, likes fertile soil, can grow well in ordinary soil, and is not strict with environmental requirements. The small seedlings planted in the year can be allowed to grow naturally after watering thoroughly, irrigating times every 15 days according to the situation, combined with cultivating weeding and appropriate topdressing 1 2 times in spring and autumn every year, and generally applying thin liquid fertilizer based on nitrogen fertilizer.

Planting techniques of holly trees :

Holly sprouts long branches several times a year and is extremely resistant to pruning. In summer, it is necessary to shape and prune times, and in autumn it can be pruned flat or pruned into a spherical and conical shape according to different greening needs, and appropriate thinning is carried out to maintain a fixed crown branch state. In places where it is colder in winter, measures such as piling soil to protect against the cold can be taken.

Planting techniques for holly trees three:

The diseases of holly are mainly leaf spot, which can be controlled by carbendazim and chlorothalonil.

Planting techniques of holly tree four:

Holly breeding is generally based on cuttings, mostly in May and June. The lower leaflets can be cut from the middle and upper part of the canopy, and the 5 10 cm long, vigorous side branches can be cut off, and the upper leaves are all retained. Then treat it with rooting powder, cut it down and cut it into the seedbed.

The seedbed should be selected in a ventilated and shade-tolerant place, and it can also be shaded and cuttings, and the survival rate is extremely high.

For holly trees, cuttings can be carried out all year round, and cuttings propagation is one of the main propagation methods of holly, because cuttings propagation is relatively simple, rooting is also very fast, and the survival rate is naturally very high.

First, the choice of cuttings seedbed.

Generally speaking, the seedbed for holly cuttings needs to be selected with relatively high terrain, loose soil and good drainage. After clearing the excess grass roots and stones, it is best to make the seedbed into a high furrow of about 1 2 meters, and at the same time spray drugs to remove underground pests and harmful germs.

Second, the selection of cuttings and seedlings.

Holly can be grown all year round, but late spring, early summer, and late summer and early autumn are most suitable. But if you choose to take cuttings in winter, you need to do a good job of insulating the holly tree. Cuttings need to be selected with excellent lignified or semi-lignified shoots of the year.

After the cuttings are cut, dip them in 500 ppm naphthalene acetic acid or 200 ppmabt rooting powder for 5 seconds, then cover them or wrap them in agricultural film to prevent drying.

3. Cuttings process.

When cuttings for holly trees, it should not be too deep, and it is advisable to put the mother plant into the soil for 1 cm. The row spacing of cuttings is generally 12-15 cm, and the plant spacing is 6-8 cm. Depending on the size of the leaves, each leaf is cut 1 2 to 2 3 to reduce excessive water and nutrient consumption.

Fourth, plugging management.

After the holly cuttings, you need to build a shed to shade and keep the seedbed soil moist, you should water frequently, and the topdressing of cuttings can be combined with watering, and at the same time, you must not forget to carry out weeding work.

5. Transplantation. Generally, after two or three months of cuttings, holly trees have taken root, continue to maintain for a period of time, and wait until the new roots grow to 1-2 cm, you can transplant, generally speaking, the success rate of cuttings is more than 95%.

First, seedbed selection.

The cuttings seedbed should be selected from the plot with high terrain, deep soil layer, loose soil and good drainage and irrigation. After removing grass roots and stones, it is formed into a high furrow of about 1-1 2 meters, and 10 imidacloprid 1000 times plus 5 mancozeb 1500 times are poured to remove underground pests and harmful bacteria. After the seedbed is leveled, it is flattened with a shovel, poured with 10 decaying rare human feces, and then the bed is covered with a layer of sieved charred marl or yellow clay with a thickness of about 5 cm.

Second, the selection of cuttings.

French holly cuttings can be done all year round, with the most suitable in late spring and early summer and early summer and early autumn. Winter cuttings should do a good job of insulating the seedbed. Cuttings are selected, and excellent branches with lignified or semi-lignified branches are selected to be the most likely to survive.

After the cuttings are collected, the cutting should be carried out in a cool leeward place, and the knives and scissors used should be sharp.

Techniques for planting holly seedlings.

1. Pick the ground for planting: holly is a kind of vegetation that likes to be cool and wet, and it likes to grow in places where the temperature is cool and humid. Although it can grow in normal land, it is best to plant it in land with enough nutrients and water if you want it to increase its total output.

2. Take care of fertilizer and water: As we have said before, holly is a kind of vegetation that likes a humid environment, and it has no way to develop without water, so we should water it as soon as possible when planting.
