Seeds oval, with a central groove, taupe. Growth habit] [genus sun plants, like light, half shade tolerant. Propensity to high temperature and humidity, hot resistant, but also hardy. Optimum growth temperature 20 ~ 30 ℃, winter temperature of a 5 to a 10 ℃, but there are records survive at lower temperatures. Extremely wind. Salinity, poor resistance, rapid growth in the fertile soil. Humus loam containing the best, need good drainage. When planted need Shizujifei regularly after transplanting fertilizer, organic fertilizer, inorganic fertilizer can be. Tropical and subtropical areas can open field cultivation in the Yangtze River in winter need a little cover, the Huang-Huai region need interior insulation winter. [Use] Phoenix canariensis garden full of tropical charm, a beautiful stretch of its tree, stem diameter at breast height of 50cm or more often, with closely spaced flat diamond-shaped leaf scars and relatively flat; leaf green Zhuang Wang, pinna tough; tree open semicircle, a distance of Romania as softened umbrella, rich tropical, potted plants for interior layout can also be exposed to outdoor planting, growing ranks of whether or clump planting, have very good viewing. Used in parks landscaping, green way street, is very effective. Its mature trees resistant to low temperature of minus 10, one of the hardy palm plants in the strongest of the species. Although the species is native to the island, but also very adaptable inland climates. Cold also strong, to be planted in tropical and subtropical climates. Its spherical crown, golden ear, diamond leaf scars, stout stems and long, feathery leaves great ornamental value, currently in the area south of the Yangtze River and for landscaping, especially in Shanghai, Chongqing, Changsha, etc. land, which used to create a tropical landscape. [Management] transplant transplant when the pit is greater than the conventional soil ball, usually high 1.5m, width 2m. Bottom put a layer of broken bricks, sand holes and a layer above before planting. When planted at the bottom to sprinkle 'carbofuran' or powder. To prevent insects. Other parts containing humic loam or sandy soil cultivation, namely moisturizing good drainage. After the general tree planting, soil ball higher unearthed Table 5-10cm, so that the soil surface at a 45 degree angle. Covered with sand, on the upper part of the best kinds of tiny plants, soil erosion protection role. [Spraying] 1, granules Pharmacy; would Sinon Dan with medical gauze wrap around 50-100g per pack can be placed on the leaf area, put 3-4 per plant package; along when planting trees around evenly spread circle, January / times; (Note: 3% of the participating countries Sinon Dan carbofuran ingredient efficacy, as both can also be used alone or mixed) 2, emulsifying Prevention: Good for partners (chlorpyrifos) 200ml + release wins cells (beta a Saining) 200ml + thugs 100g + multifunctional agricultural surfactant watered 300l 3, insecticide dimethoate Wang 200ml + 150ml +1605 150ml + 100ml watered 300l spreading agent Note: Several pharmaceutical emulsion prevention should be used interchangeably to avoid the tree resistance. [Phoenix canariensis black spot disease] black spot disease hazards Phoenix canariensis, Chinese fan palm, causing yellowing dry. Have occurred in Guangdong, Fujian and other places, diseased leaves appear small macula, enlarged round or oblong, 2-5 mm in diameter, dark brown, clear edge, there is a wide peripheral yellow circle. Scattered on both sides of the lesion or Qun, nearly circular black grain points, 0.6-1 mm high and 0.2-0.3 mm wide, most central cracking, sometimes produce some yellow-white granular substance on it, numerous severe leaf lesions, variable yellow dry. Pathogen stylina disticha (erenb) syd. Genus Trichosporon Gang, Trichosporon mesh, Palmetto Powder Tower bacteria. Pathogens overwinter in sick organization, all year round disease. In warm weather the rainy season, or planting too close, poor ventilation, high humidity environmental conditions, disease occurrence heavier. Prevention: The disease begins in the spring can be 50% carbendazim 600-800 times; or new Wansheng 600 times; 500-600 times spraying or high birth control. [Adaptation] 1) climate Phoenix canariensis Canary Island of the West Bank, the African origin, in tropical to subtropical regions can open field cultivation in the Yangtze River in winter need a little cover, the Huang-Huai region need interior insulation winter. Its plant heat and cold resistance are strong, mature trees can withstand -10 ℃ low temperature. 2) ecological adaptability Phoenix canariensis evergreen trees. Hi warm and humid environment, like light and shade. Annual seedlings adapt to the environment than the shade, shade 50% better in general. Mature trees adapt sunny environment. Data shows that Phoenix canariensis minus 10 ℃ low temperature capability, but still need to be confirmed. Currently proposed in the above areas to promote winter minimum temperature of minus 5 ℃. In terms of soil adaptability, as long as no water, almost all kinds of soil, including soil salinization bias can grow. Hi strong light, shade intolerant, high temperature, drought, but also resistant to a certain degree of pollution. It is rich with unique characteristics of subtropical plants, becoming one of the high-end landscaping trees. Phoenix canariensis is an advanced world famous landscape tree, tree tall, magnificent, beautiful, shiny green leaves. Single trunk, erect, up to 10 --- 15 m height, stem diameter is 50 - 90 cm. Leaf, feather, top students from out to the Quartet started to form diameter of 6 - 8 m circular canopy. West African origin of the Canary Islands. Xiamen Botanical Garden, the first country from abroad, introduction nearly 40 years, performed well. Xiamen Botanical Garden's Palm Island, a charming landscape, the landscape of the park is the most beautiful place. Phoenix canariensis naturally strong, both high temperature and resistance to frost; both drought-resistant, and resistant to flooding; both acid resistance and alkali soil. Soil ph5 --- ph8.3 can grow normally in, but also its wind, is an excellent seaside plants. The only drawback is that to prevent infection borer, red palm weevil and coconut coconut A (see Phoenix canariensis control methods of pest control). Phoenix canariensis as a landscape tree upscale abroad have been recognized by many national park units and the general public alike.
