Eucalyptus cultivation

Eucalyptus cultivation

The banyan tree, also known as buckwheat, is a genus of the genus Amaranthus. The tree grows fast, its color is light purple, and it has fragrance, less pests and diseases, and the fruit is spherical. When it is ripe, it is light yellow and it does not fall through the winter. It is one of the first tree species for urban afforestation.
First, the nursery has chosen to choose a deep and fertile soil layer, a low groundwater level, good drainage, no source of pest infestation, and a flat sandy loam soil. Drainage ditch should be dug around the nursery, so that the internal water does not accumulate, and the external water is not flooded. In order to facilitate management, seedbeds and walkways should be kept separate. The seedbed should be 1.2 meters wide and the walkway should be 40 centimeters wide.
Second, nursery containers using plastic film bags, in the bottom of the bag to punch or cut the bottom corners.
Third, the preparation of nutritious soil The formula of nutrient soil is: 95% of forest soil, 3% of superphosphate, 1% of potassium sulfate, 0.5% of ferrous sulfate. In order to prevent pests and diseases of eucalyptus, nutrient soils need to be disinfected. Use 25 kg of 3% ferrous sulfate per cubic meter of nutrient soil, mix and cover with plastic film for 24 hours. Do not use manure, vegetable soil or other mature soil. The nutritious soil is lightly compacted after filling the container and the soil surface is 0.5 to 1 cm below the container. The containers packed with nutritious soil were arranged neatly inside the baskets. Each row consisted of 15 bags, arranged in the shape of a product, and excavated and sealed around the seedbeds.
Fourth, sowing spring seeds of eucalyptus need to be germination treatment, first exposed to the sun for 2 to 3 days, soaked with 80 °C hot water, let it natural cooling, and then soak for 1 to 2 days. The seeds were swollen and swollen and mixed with 3 times the wet sand. The plastic film was used to germinate on a warm bed. After about 10 days, the seeds began to germinate, and when one-third of the seeds were exposed, they were sown. Usually sowed from March to April. Each bag should be sown with a thickness of 3 times the seed diameter.
V. Seedling management
1. Watering eucalyptus should be quantified timely when watering, and watering should be sufficient for the first time after sowing. Before the seedlings are unearthed, spray water every morning and evening. Seedling stage and seedling stage should be repeated for quantitative pouring, and the fast-growing period should be a large number of small and small times. In the later stage of growth, irrigation should be controlled, and water spray at high temperature at noon should be avoided.
2. Fertilization of eucalyptus topdressing requires that the nitrogen, phosphorus, and potassium nutrients be mixed and sprayed. It is strictly forbidden to apply chemical fertilizers. After dressing, rinse the leaves of the seedlings with clean water. In the fast-growing period, nitrogen fertilizer is the mainstay. After the fast-growing period, the application of nitrogen fertilizers will be stopped, and phosphorus and potassium fertilizers will be appropriately increased to promote the lignification of seedlings and increase the cold resistance of the trees.
3. The seedlings of Eucalyptus tend to sprout in clusters after sowing and the seedlings are not uniform. About 10 days after the seedlings emerged, rainy day seedlings were selected, and one robust seedling was kept in each nutrient.
4. Prevention and control of pests and eucalyptus eucalyptus seedlings 1 to 2 months after emergence, easy to suffer from damping-off disease, can be sprayed every 10 to 15 days equal amount of Bordeaux mixture or 0.5% to 1.5% ferrous sulfate solution, spraying Pay attention to spray on the lower part of the seedling stem to eliminate the bacteria in the soil.

The Greenhouse Film Electric Roll-Up Unit replacing traditional manual roll-up unit to reach high speed automation in revolving & releasing films and greenhouse environment, it is the new generation of greenhouse ventilation and temperature regulation facilities. Portability, output torque, output lock, wide range and precise adjustment, waterproof, dew-proof and power-saving are the key characteristics for Electric Roll-Up Unit, which is the best choice for modern daylight greenhouse applied in different climates.
