Cultivation Techniques of American Red Maple Tree
The American Red Maple, a genus of eucalyptus trees of the eucalyptus family, also known as the Canadian Red Maple, native to the eastern coast of the United States, deciduous trees. Faster growth, adult tree height of 12 to 18 meters, 12 meters crown, can adapt to a wide range of soil type growth. Spring blossom, flower red. Due to its colorful autumn colors and canopy neatness, it is widely used in parks, communities, and streets to plant trees. It can be landscaped and landscaped. It is deeply loved by people. It is an ideal and rare landscaping and greening garden that was introduced in recent years. One of the trees. The nursery technology is summarized as follows: First, the nursery to select and handle the United States Red Maple seedlings should choose slightly acidic, moist, good water permeability, good irrigation conditions of sandy loam. Before sowing, 5000 kg of organic fertilizer and 50 kg of NPK ternary compound fertilizer are applied per acre. In order to prevent seedling pests and diseases, especially the underground pests, 8~10kg of ferrous sulfate and 2kg of phoxim granules per mu need to be mixed with fine soil and sprinkled on the surface, and then deep plowing, fine pounding, and flat plowing are required. It is 1 meter wide, 30 centimeters wide and 20 to 30 meters long. Second, seed treatment, sowing time and method The United States red maple seeds do not have dormancy, both for autumn and spring broadcast, is mainly introduced spring sowing. The sowing time is appropriate from mid-March to mid-April. Before sowing, mix the seed and wet sand in a ratio of 1:3 and put them on a low-temperature sand trap for 3 months at 3～5°C. During the stratification period, regular inspections and management are required, and germinating seeds are found and sowing must be carried out in a timely manner. When planting, first fill the bottom water in the pot and wait for the water to seep and sow again. The sowing volume per square meter is about 200 grains. After sowing, it is necessary to cover 0.5 cm of fine soil, in order to keep the ground warmer, so that the seed germination early, budding and neat, can cover the film or small arch shed, arch shed should pay attention to ventilation, noon temperature should exceed 30 °C appropriate shade. Generally about 15 to 20 days after sowing, the seedlings will be produced. Third, seedling management and growing seedlings unearthed, the initial growth is slow, poor resistance to frequent water spray, maintain soil moisture, and timely removal of weeds, hoeing grass timely soil, try to cultivate more soil, to prevent lodging phenomenon. When the seedlings grow to 5 cm in height, they will be seedlings, usually after irrigation, and the weak, sick and seedlings will be removed at intervals of 10 to 15 cm to keep the seedlings robust and tidy. Where the seedlings are lacking, rainy days are recommended for transplanting with soil balls. . In early June, topdressing urea with water, 15kg per mu, in mid-July, topdressing urea 10 ~ 15kg per mu, appropriate water control in the later period. If pests such as moths are found, they can be sprayed with 2.5% deltamethrin 4000 times for control. The seedlings can reach a height of 1 to 1.5 meters in the year and can be planted in the second spring.
