Toon tree planting method:

One, choose high-quality seeds

Select the new seeds of the year, the seeds should be full, fresh in color, reddish-yellow, yellowish-white seed kernel, the purity is more than 98%, the germination rate is more than 40%.

Two, insulation germination

In order to emerge neatly, need to be germinated. Germination method is: 40 ℃ of warm water, soak the seeds for about 5 minutes, stirring constantly, and then placed in 20 ℃ ~ 30 ℃ of water immersion for 24 hours, the seeds absorb enough water; fish out the seeds, control excess water, put on a clean reed mat, spread 3 cm thick, and then covered with a clean cloth, placed in a 20 ℃ ~ 25 ℃ environment of humidification germination.

Germination period, turning the seeds 1 to 2 times a day, and about 25 ℃ of water to wash 2 to 3 times, control the excess water. When 30% of the seeds sprout, they can be sown.

Three, timely sowing

Selected flat terrain, light, well-drained sandy soil and fertile soil as seedling plot, combined with the land fertilization, spreading, turning through. In a 1-meter wide bed according to 30 cm row spacing ditch, ditch width 5 ~ 6 cm, ditch depth of 5 cm, will be well sprouted seeds evenly sown, covered with 2 cm thick soil.

Four, seedling management

Seedling about 7 days after sowing, not before the seedling strict control of watering to prevent the soil from knotting affect the emergence of seedlings. When the seedlings out of the soil to grow 4 to 6 true leaves, should be inter-seedling and set seedling. Seedling before watering, to plant spacing 20 cm seedlings.

When the plant height is about 50 centimeters, carry out dwarfing treatment of seedlings. With 15% polyoxazole 200 to 400 times liquid, every 10 to 15 days to spray 1 time, even sprayed 2 to 3 times, can control the growth, promote seedling dwarfing, increase the accumulation of material. Combined with centering at the same time as the doxorubicin treatment, it can increase the number of branches.

Five, fine management

Temperature management: the first few days without heating, so that the temperature is maintained at 1 ℃ ~ 5 ℃ in order to facilitate the slowing down of seedlings. Planting 8 to 10 days after the shed covered with straw thatch, uncovered during the day, the night cover. So that the temperature inside the shed during the day control at 18 ℃ ~ 24 ℃, 12 ℃ ~ 14 ℃ at night. In this condition after 40 ~ 50 days can grow toon buds.

Hormone regulation: after planting and slowing down the seedling with twitching treasure for treatment of the upper 4 to 5 dormant buds of the toon seedling with twitching treasure positioning coated with 1 gram of medicine coated with 100 to 120 buds, coated with the drug can make the bud body full, the shoots are strong and robust, and the yield can be increased by 10% to 20%.

Humidity regulation: the first planted to the greenhouse toon seedlings to maintain high humidity. Water thoroughly after planting, and later water small water as appropriate, the relative humidity of the air should be maintained at about 85%. During the growth period after sprouting, the relative humidity is good at about 70%.

Light regulation: toon likes light, should try to use non-drip film, timely unveiling of grass thatch during the day, paper quilt, but also often sweep the film debris to increase the light, if the light is too strong, can be appropriate to cover the grass to shade the sun.

Sixth, fertilization

Daylight greenhouse cultivation of toon must apply enough bottom fertilizer. Each mu of high-quality farmyard fertilizer not less than 5000 kilograms, not less than 100 kilograms of calcium superphosphate, 25 kilograms of urea, sprinkled evenly and y turned. Then the whole bed planting seedlings, the general width of 80 ~ 100 cm

seven, planting density

planting density to plant about 30,000 per mu, plant spacing 15 cm, row spacing of 15 cm is appropriate.

Propagation methods:

The propagation of the toon is divided into two kinds of sowing seedlings and planting propagation (also known as root tiller propagation).

I, split-plant reproduction

Split-plant reproduction, can be dug in the early spring into the root of the plant seedlings, planted on the seedling ground, when the next year the seedling grows to about 2 meters, and then planted. Can also be used to break the root tiller method, in late winter and early spring, in the adult tree around the digging 60 cm deep circular ditch, cut off part of the lateral roots, and then fill the ditch, because the root of the toon is easy to give birth to the adventitious roots, so the apex of the broken root sprouting new seedlings, the following year can be transplanted.

After transplanting, spraying new high fat film can effectively prevent the ground water does not evaporate, the seedling body water does not transpire, isolate pests and diseases, shorten the period of slowing down the seedling. Toon seedlings after breeding, are planted in early spring before germination. Large area to create toon forest, row spacing 7x 5 meters. Planted in the river canal, behind the house, are single row, spacing about 5 meters. After planting, watering 2-3 times to improve the survival rate.

Two, sowing seedlings

Sowing propagation due to the low germination rate of toon seeds, therefore, before sowing, the seeds should be added to the new high fat film soaked in warm water at 30-35 ℃ for 24 hours, picked up, placed at 25 ℃ to germinate. Until the radicle reveals the size of rice grains when sowing (sowing the ground temperature at a minimum of about 5 ℃) Shanghai area is generally in early to mid-March. After the emergence of seedlings, 2-3 pieces of true leaves time seedlings, 4-5 pieces of true leaves when the seedling fixed, row spacing for 25x15 cm.
