Hemlock spruce Silvicultural techniques

Seedling seed: the adult healthy tree seed, when the cones turn brown, scales of micro crack, can be collected. The cone back and forth after exposure to spread thin, a solution of cracking, seed emergence, rub to fin, wind net cleaning, dry storage, spring sowing.
Nursery: He Zi irrigation convenient sandy loam, short of sunshine. Fine roots rake up the gravel, debris, enough base fertilizer, careful preparation, the bed on the whole, drill or broadcast, per mu from sowing sowing rate, 10 kg, 4 kg of drilling. After sowing, covered with yellow soil, thickness to seed for the degree, the affix straw, to be a bud dew soil, removal of Geiger. At the seedling stage, Le weed, forcing the appropriate fertilizer, pay attention to the prevention of epilepsy pests, every half a jet 1% equivalent Bordeaux, day early and timely irrigation, summer heat, a meteorite shed shade, and appropriate thinning time. The garden of transplantation. Hemlock, Zhuo period of slow growth, 3 - 5 years should be in nursery cultivation, it can be used in afforestation.
Afforestation method: hemlock The positive roots of tree species. But the temperature of ice, humid climate, like acidic or neutral sulfur loose, fertile soil, mountain yellow brown soil. From the point of view of Wuyishan natural forest, South and North are distributed, but in sunny growing more prosperous. Natural seeding seedlings to 6, 7 old trees, still can shade, with the age growth, the corresponding requirements increase the light, otherwise poor growth. Selection of planning afforestation land, should first consider the higher elevations of the mountain, the mountain sunny or semi sunny slope, cut the firing mountain reclamation, digging, cave 50 x 60 cm. Must pay great attention to the hemlock trees, the survival rate, which is just a ring in the garden digging Zhuo wood, avoid damage to roots, so as not to affect the survival rate of afforestation, and to do with the seedling with planting. Choose the bright rain or rain day planting trees, planted before the root with the mud, do Shu root, is planted, matter.
Tending: due to slower growth of juvenile hemlock, can shade, total forest management can be combined with forest crop intercropping, but intercropping years, generally 3 to 4 years. Intercropping stop after every year must be weeding. The forest canopy, according to the needs of weed and soil management, soil and cut miscellaneous alternate, trees begin to differentiate, timely thinning, according to "stay in addition to small, in addition to stay strong weak, stay thin Chen close" principle, cutting of pressed wood, wood, wood pest wind break etc..

Hemlock spruce Garden use

Hemlock trees are simple, suitable for Rachelson, with branches profusely covered with leaves., garden plant alone or planted, should also be used to create mountain scenic forest or water conservation forest. Hemlock branches, cut resistant, also suitable for hedge. In addition, because of its slow growth, it should be potted.

Hemlock spruce Other uses

By pressing antiseptic treatment of hemlock wood is beautiful and strong, and indeed the natural durability comparable to the red cedar.
