First, the family flowers and flowers plastic trim points
(1) Heavy shear
Flowers on annual branches such as jasmine, crape myrtle, and rose are suitable for heavy cutting, while those on biennial branches are heavy cut. The knife used in pruning should be sharp to ensure that the clippings are smooth and prevent cracking. In addition, the leaves of buds that grow outside should be selected for trimming to facilitate uniform outreach of the branches. This will not only make the plants beautiful in shape, but also conducive to ventilation and light transmission.
(2) Shear
Prunes like pomegranates, kumquats, and waxy plums must be properly shortened before they can be used to create good flowers. In addition, it is necessary to sparse and cut both weights. For the annual branches that have been flowered, 2-3 bud short cuts should be left in the stems, so that it is easy to extract lateral branches and to remove leggy branches, cross branches and diseased branches.
(3) Light shear
The flowers on the 2-year-old branches, such as Bitao, Bailan and Gardenia, are suitable for light-cutting, and only the excess lateral branches, diseased branches, and tip shoots are cut so that the main branch can be strong. In addition, when pruning, artificial shaping can be performed according to personal preferences and plant growth conditions, such as umbrellas, pagodas, and the like.
(4) Topping
Herbs such as daisies, calendula, and violets have to be picked many times and headed for multiple lateral buds. The plants are short and beautiful, so as to increase the number of flowers and prolong the flowering time. In addition, after the flowers are cut off, the residual flowers should be cut off in time and the rest of the flower heads should be promoted.
Second, the selection of flowers in the soil taboo
(1) rotolin
Fungus leaf is the topsoil of forest area. The deciduous leaves of broad-leaved trees are long-term accumulation and decomposed, containing large amount of organic matter, loose and fertile, good permeability and drainage, and weak acidity. It is an excellent loosening agent for viscous heavy soils. Fertility is strong and can be used alone to cultivate Clivia, orchids and cyclamen. In the autumn and winter seasons, local materials can be collected, and the leaves of broad-leaved trees can be collected (such as perishable leaves such as poplar, willow, alfalfa and wolfberry), and piled together with garden soil for 1-2 years until the leaves are fully rotted and can be sieved. Ordinary humus is an excellent potted soil and can also be mixed with other substrates. Suitable for sowing, transplanting seedlings and cultivating a variety of common flowers.
(2) Pine needle soil
In the mountain forests, the deciduous pine deciduous humus, the pine needle soil. Pine needle soil is gray-brown, loose and fertile, has good air permeability and drainage performance, and has a strong acidic reaction. It is suitable for azaleas, gardenias, camellia and other hi-acid flowers.
(3) peat soil
Peat soil, also known as black soil and peat, is made from the remains of plants in low temperature and wetlands and carbonized by the action of peat moss for thousands of years. The peat soil is soft, loose and free from pathogenic spores and harmful eggs. It has good drainage and air permeability, and has strong retention and storage of water and fertilizer. It is a weak acid reaction. It is a good potting soil and cutting substrate. In the northern part, brown turf charcoal is used to prepare nutritious soil, and it is more appropriate to use cultivated charcoal soil to cultivate orchids, camellia, sweet-scented osmanthus and white orchids that are native to southern China.
(4) pond mud
Tang mud, also known as river mud, is a sedimentary soil of river bottom pond, rich in organic matter, black, neutral or slightly alkaline. , Generally, in the autumn and winter seasons, the silt in ponds or lakes is harvested. After drying and freezing, it can be the best cultivation soil for aquatic flowers. After dried and crushed, it can be mixed with coarse sand, husk ash or other light loose soil, and can be used for planting foliage flowers.
(5) turf soil
In natural pastures or grasslands, 10 cm of surface turf is dug and layered. After one year or longer of decomposing, the stones and grass roots are removed by screening. The turf soil is rich in nutrients and has a weakly acidic reaction. It can be used to plant rose, carnation and Dali flowers.
(6) Swamp soil
After the wetlands have dried up, their surface soil is a good raw material for pots and earths. Swamp soil is rich in humus, long-lasting fertility and acidity. However, after drying, it is easy to be hardened and cracked and mixed with coarse sand. The nutrient soil for flower cultivation must be made of nutritious ingredients and contaminated soil must be avoided.
