Shandong Shuhai seedling base provides you with low-priced fast-growing poplar seedlings. Fast-growing poplar trees are all black poplar clones, which are Excellent varieties of poplars have been bred from American black poplar and European black poplar. Varieties include American black poplar, Nankanghao, Nankanghao, Chinese poplar, Chinese poplar, and European black poplar. They are all excellent poplar varieties bred in recent years. These poplars grow fast and have strong resistance to diseases and insect pests. The annual diameter at breast height is up to -cm, which is one larger than ordinary poplars. Especially the American black poplar Nankang Zhenyang and Yangzi, Yangnankang Nankang poplar are new varieties identified in this year. The three poplar varieties are fast-growing, have straight trunks, and have strong resistance to clouded beetles. The average diameter at breast height of annual poplar reaches .cm, Yangzi and Yangzi reach .cm, and the average diameter of Nankang poplar reaches 3.3 cm. They are suitable for planting in lake areas and other places. Its characteristic is that it requires a warm climate and sufficient rainfall. The fast-growing poplar is suitable for planting in lake areas, mountainous areas, hilly areas, valley alluvial flats and "all around". The soil should be moist, fertile, deep and well-drained. It is most suitable to grow on alluvial sand dunes and mounds with a soil thickness of more than 1 meter, a groundwater level between 1 to 3 meters, a pH of 1 to 3 meters, and a salt content of less than 1 meter. Fast-growing poplars are easy to reproduce and grow rapidly. According to the Yuanjiang Municipal Forestry Bureau, if strong annual seedlings are used for afforestation, the height of the trees will increase by 3 to 3 meters per year within two to five years, and the diameter at breast height will increase to centimeters per year. The growth rate of the forest per mu .to cubic meters. Fast-growing varieties of poplar trees identified in 2018: Zhonghongyang (Chinese red-leafed poplar), poplar, poplar, poplar, Zhonglin poplar, red poplar, etc. Characteristics of fast-growing poplars in later years: The leaf color of medium red poplar (Chinese red poplar) changes with the seasons. Males have no flying catkins and do not pollute the environment. They can become useful in just one year. It can be used as both landscaping and fast-growing and high-yielding forest, and has been well received and affirmed by all circles of gardening. The characteristics of new fast-growing poplars such as poplar and poplar: resistance to diseases and insect pests, tolerance to drought and waterlogging, and strong adaptability are favored by growers. Fast-growing poplar trees can generally be cut down in one year, which is about a year faster than ordinary trees. The volume of a single annual tree can reach .3 cubic meters, and the annual net income per mu can reach about 3 yuan. Function introduction ⒈ Morphological characteristics: American black poplar hybrid, with the morphological characteristics of American black poplar. Tree, tall tree shape, straight and round trunk, small taper, medium branch thickness, thin bark, large leaves, heart-shaped, leaf length ~ cm, leaf width ~ cm, leaf color green, petiole length ~ cm , light green annual branches are grayish blue, the shape of the base of the branches is round, the middle and upper parts are slightly pentagonal, and the lignification ridges are obvious. The lenticels are round in the middle and lower parts, and oval at the top. The size of the lenticels is ~ mm. Annual transplanting seedlings The height of the seedling is ~.m, with a base diameter of 3 cm. The number of leaves is between ~. The buds are oval, light purple-red, with a green base, ~ mm long, and the top is pointed and not close to each other. ⒉ Phenological characteristics: Flowering occurs from month to day, bud germination period occurs from month to day, leaves are released from month to day, and leaves first fall. The entire growth period lasts for many days. ⒊ Growth index: The annual tree height and growth are ~ meters, the average diameter at breast height is 3 to 3 cm, and the volume of a single tree is . m/ha, one year is a rotation period, and each hectare can produce 1.3 cubic meters of high-quality veneer poplar wood. ⒋ Adaptability and resistance indicators: Resistant to canker disease and brown spot disease, relatively drought-resistant, with thin ridges, and grows well on inland piebald saline-alkali land. The volume growth is 3. higher than the control I-poplar. It has strong asexual reproduction ability and relatively stable genetic stability. It can promote afforestation in the Huanghuai region, Jianghuai Plain and the vast areas of Zhejiang, Fujian and Guangdong in the middle and lower reaches of the Yangtze River. ⒌ Cultivation characteristics: Nanlinyang likes light, water and fertilizer. It grows very quickly when there is sufficient light, water and fertilizer. The density of field seedlings is ~ plants/acre, the length of the ear strips is centimeters, and the cutting season is from mid to late March in spring. In northern Jiangsu area, water should be irrigated once after planting. The density of the forest used for veneer is ~ plants/acre, and the hole is The specifications are length × width × height (××cm), the planting depth is ~cm, and the bottom of the water is filled with water. The planting time is from after the poplar leaves fall in autumn to before the buds sprout in late March in spring. Try to do local seedlings and local afforestation. With planting, the time between seedling emergence and planting is shortened to ensure the survival rate of afforestation. ⒍ Usage: Mainly used for poplar veneer timber afforestation varieties, and can also be used as fiber board timber, pulp timber and other industrial timber afforestation varieties. In addition, it can also be used as farmland tree netting, tree planting and other greening varieties.
