1, toon like warm, toon tree seedlings the larger the ability to withstand the cold is stronger, so the general planting selection of large seedlings for planting, out of the toon buds will be more, toon is suitable for cultivation in the area of the average air temperature of 8 ~ 10 degrees, toon split seedling cultivation of toon seedling, than the use of seedling seedling made of toon seedling, to be able to collect the buds of the time to be early.
2, toon suitable transplanting time, toon has a dormant period, fall leaves in the fall automatically into a dormant state, generally around New Year's Day dormancy is completed, the toon real dormant time is generally about three weeks on it. Transplanting toon seedlings, arranged in the spring after New Year's Day, transplanting before the toon did not sprout, the survival rate is the highest, in April of that year you can pick a small number of toon buds.
3, the density of toon planting, to pick buds mainly toon seedlings, at the end of the dormancy of the toon, before the sprouting can be transplanted, open-ground planting of toon seedlings, planting about 280 to 300 per acre, open-ground planting of toon buds sprouting relatively late. As a greenhouse counter-season planting of toon sprouts seedlings, the economic benefits are much better than the economic benefits of open-ground planting, the planting density per mu should be larger, generally around 500 to 520 trees per mu.
4, toon seedling method, (1) seed direct seeding, each acre of land needs to be prepared in advance of high-quality seeds 3 ~ 4 kg, choose loose and fertile field soil, soil pH 5 ~ 8, especially rich in organic matter, loose and fertile sandy loam soil is good. Choose high-quality toon seeds, soaked in 40 warm water and rubbed off the wing membrane of the seeds, fishing out the blighted seeds, the rest of the seeds after scrubbing and rinsing with water, and then placed in the dark at 25 ~ 30 degrees Celsius to germinate the seeds, the seeds have 60% of the emergence of white embryonic roots can be sown after the emergence of white embryonic roots.
(2) sowing, generally choose row spacing of 20 centimeters, sowing width amplitude of 7 ~ 8 centimeters, covered with 1.5 centimeters thick fine damp soil, covered with mulch to keep moisture and increase temperature, about after 5 ~ 7 days, toon will come out of the seedling, in order to reduce the uncovering of the film caused by the toon has destroyed the phenomenon of the buds, toon buds have 30% of the seedling on the uncovering of the mulch, and plowed weeding, inter-seedling, spraying Foliar fertilizer to promote growth and other work. Seedlings of the year, can be planted after New Year's Day, the second year can pick a small number of toon buds on the market,
(3) split-plant reproduction, planting less can be used to split-plant seedling method. The root system of the toon has a strong germination ability, choose to cut off part of the root system around the crown of the adult tree and watering, soon by the broken root system at the re-sprouting to form a new plant, but also in the original seedling place, the seedling is taken out and immediately watered, to promote the remnants of the root system in the soil to continue to sprout into a new plant. Then routine management can be carried out, after entering the dormant period, can be transplanted and planted.
