How to cultivate camellia?

Camellia cultivation techniques are as follows:

1. Site preparation: Choose a warm and humid environment, good drainage, loose and fertile sandy loam, loess or humus. pH 5.5-6.5 is the best. Neither alkaline soil nor sticky soil is suitable for planting camellia.

After selecting a good ground, turn it deep, apply the bottom manure, and level the rake thinly to make a height of about 120cm.

2. Breeding methods include seeding, cuttings, beading, and grafting. In actual production, cutting propagation is often adopted. Select robust and disease-free shoots of that year as propagation material. Each section is cut into sections, and the upper part of the leaves is cut off at 0.4-0.5cm. The cut cuttings are planted on the prepared rafters at a row spacing of 18-21cm and plant spacing of 6-9cm. After the cuttings are all done, water them with a watering can and set up a shade on the cuttings.

In addition, in garden greening, for ornamental purposes, it is possible to use large flower camellia and wild camellia seedlings for docking, and do a small number of single plant propagation, which is not suitable for large-scale cultivation of seedlings.

Transplanting: When new roots of camellia grow and the plants grow 50-80 cm in height, transplant them. Camellia is often mixed with forests for afforestation. The transplanting method is to transplant each spring. On the prepared land, dig a pit with a diameter of 50-70cm, mix the pit soil and the decomposed compost evenly, apply it into the pit, and then dig the camellia seedlings into the pit with soil. Cultivate water.

Potting method: Use light loam, ash slag, alum fertilizer water, triple earth, bottom of the pot with 3cm thick fine ash slag, and then install an appropriate amount of pot soil, which accounts for 1/3 of the pot. Add more water and wait for water to seep into the soil. Camellia seedlings planted in pots. Fill the soil with soil to compact 1.5cm along the edge of the pot. Generally, the pot soil is changed once a year. For slow growth, the soil is changed once every two years. Keep the basin moist. Water less at noon in winter, and more in spring and autumn, so that the soil in the basin is squeezed into a ball by hand and loose. Water in the summer but don't have water in the pot, otherwise the roots will rot. Water is poured by river or rain, followed by pond water. If the well water must be sun-dried before watering, and the roots are prohibited to be exposed, cold areas should be wintered in facilities agriculture or greenhouses or houses.

3. Field management After the camellia cuttings are cut, they need to be carefully managed frequently. The soil should be kept moist. However, it is not easy to apply more fertilizer. In the management process, the fertilizer (200-250kg of alum fertilizer water with black alum, 5kg of soybean cake, 15kg of pig manure) is prepared, and it needs to be soaked for 5-15 days. The longer the soaking time, the greater the fertility ) Watering flowers alternately, fertilizing water from spring to February, and in the early evening when the sun sets, increasing the number of times. May to June, 4-5 times of pouring, increase in July, decrease in August, stop pouring in September. Watering principle is dry and wet. Pruning should not be heavy pruning. Weak and weak branches should be properly cut. Camellia is a multi-flowering tree species. It is appropriate to thin the buds during pregnancy to avoid consuming nutrients and affecting plant growth.

4. Pest and disease control

Anthrax: spray with 800% solution of carbendazim, wettable powder, or 800 times solution of 50% tobbutin, once every 10 days, 3 times.

Gray spot disease: Spray with 0.6% lime half-volume Bordeaux solution.
