A seedbed of rice plants. A seedbed or seedling bed is the local soil environment in which seeds are planted. Often, it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field.
Clearcut openings of 1.2 to 2.0 hectares (3.0 to 4.9 acres) adjacent to an adequate seed source, and not more than 6 tree-heights wide, could be expected to secure acceptable regeneration (4,900, 5-year-old trees per hectare), whereas on undisturbed-unshaded north aspects, and on all seedbed treatments tested on south aspects, seed to seedling ...
Hügelkultur (German pronunciation: [ˈhyːɡl̩kʊlˌtuːɐ̯], alternative spelling without umlaut: Huegelkultur), literally mound bed or mound culture, is a horticultural technique where a mound constructed from decaying wood debris and other compostable biomass plant materials is later (or immediately) planted as a raised bed.
Among the major field crops, oats, wheat, and rye are sown, grasses and legumes are seeded and maize and soybeans are planted. In planting, wider rows (generally 75 cm (30 in) or more) are used, and the intent is to have precise; even spacing between individual seeds in the row, various mechanisms have been devised to count out individual seeds at exact intervals.
Tree planting is the process of transplanting tree seedlings, generally for forestry, land reclamation, or landscaping purposes. It differs from the transplantation of larger trees in arboriculture and from the lower-cost but slower and less reliable distribution of tree seeds .
a) Reduction of logging slash, plant competition, and humus prior to direct seeding, planting, scarifying or in anticipation of natural seeding in partially cut stands or in connection with seed-tree systems. b) Reduction or elimination of unwanted forest cover prior to planting or seeding, or prior to preliminary scarification thereto.
Seeds of many trees, shrubs and perennials require these conditions before germination will ensue. [citation needed] In the wild, seed dormancy is usually overcome by the seed spending time in the ground through a winter period and having its hard seed coat softened by frost and weathering action. By doing so the seed is undergoing a natural ...
Some plant species, including many trees, do not produce seeds until they reach maturity, which may take many years. Seeds can be difficult to acquire, and some plants do not produce seed at all. Some plants (like certain [4] plants modified using genetic use restriction technology) may produce seed, but not a fertile seed. [5]
