Ember cultivation technology

A nursery <br> <br> emblic breeding methods seedling propagation, grafting, root suckers division propagation. In order to meet the needs of the seedlings of excellent varieties, the cultivation of good seedlings and grafted seedlings is the development approach for the cultivation of eucalyptus.

1. Seed and breeding seed production Choose a mother tree that grows robustly. After the fruit leaves the tree until the winter solstice, pick it up when it is fully mature, expose it to the splinters in the sun, explode the seeds, and collect the seeds in a cool and dry place.

The sowing time is appropriate before and after the Qingming period, when the temperature and humidity are appropriate, the seedling emergence is fast and the germination rate is high. Sowing rate 3-4 kg. After the emergence of strengthening management, the general one-year seedlings grow about 50 cm high and can be transplanted.

2.Grafting and breeding can maintain the good traits of good varieties, which can be used for splicing, single bud cutting or single bud abdominal joint, etc. The rootstock stalks are as thick as about 3 cm, or grafted and grafted, grafting with splicing method, scion The 2- to 4-year-old branches with a diameter of 1.0 to 1.5 cm should be selected; the stems of the rootstock with fine stems of only 1-1.5 cm, and the annual branches with a thickness of 0.5-0.7 cm are selected by the single-bud graft or single bud.

Grafting time is usually from the vernal equinox to the Ching Ming. It is best to carry out the grafting at the beginning of the bud expansion and not budding.

3. Breeding of the ramets The roots of the biloba roots have strong wounds. After the roots are injured, adventitious buds will germinate into new plants at the wound; after that, the roots will be cut off from the mother tree and become independent new strains, which can be grafted and propagated. However, roots and shoots are less fine and rooted, and they grow more in situ. It is not easy for transplants to survive. If transplanted, it should be carried out around the Ching Ming and it will be beneficial to survive.

Second, planting <br> <br> build gardens to local conditions, the mountain slope of 15 degrees or less, the planting spacing should be 3 × 4 or 4 × 4 m. Dig deep and wide each 40-50 cm, according to the soil suitable for landfill or other miscellaneous soil fertilizer as base fertilizer.

Third, soil management <br> <br> emblic adaptability, soil management is extensive. During the growth process, timely weeding and soil improvement should be performed. Attention should be paid to the removal of weeds around the plants prior to harvesting, ie, cleaning the orchards and facilitating harvesting. After harvesting, timely cultivating and fertilizing, enhance permeability, cultivating soil to protect the roots, in order to benefit the continued high yield. According to the growth characteristics of the quince, the nitrogenous fertilizer is more prone to prolonged fertilization when it is applied to fertilization, which is unfavorable to flower buds. Therefore, avoid partial nitrogen fertilizer application. Fertilizers are dominated by phosphorus and potash fertilizers. From August to September each year and after fruit picking, combined with clean garden soil, each fertilization once, in order to facilitate tree growth and flower bud differentiation.

Fourth, <br> <br> pest control aphids, Kuwana blowing cotton: 90% of the crystal trichlorfon 1000 times, or 2000 times 20% fenvalerate spraying. These drugs can also reduce the incidence of coal smoke.

Hibiscus moths: Kill the larvae with a wire hook or 80% solution of dichlorvos 200 times into the wormhole.
