Description
Technical Field
The invention belongs to the technical field of red-leaf poplar variety planting, and particularly relates to a seedling raising device for red-leaf poplar varieties.
Background
The red poplar refers to the general name of poplar varieties with red leaves, and comprises Chinese red poplar, full red poplar, beautiful red poplar and the like. The red-leaf poplar is a new variety of red-leaf buds of black populus deltoids, and then red-leaf poplar varieties such as 'full-red poplar' and 'beautiful red poplar' are cultivated on the basis of the 'middle-red poplar'. The trunk of the Chinese red poplar is straight and round, the Chinese red poplar is similar to the black poplar in fast growth, the growth height of cutting seedlings in the current year can reach 4-4.5 meters, the maximum seedlings are higher than 5 meters, the ground diameter in the current year is about 3.5cm, and the maximum ground diameter can reach 5 cm; the growth height in two years can reach 5-8 m. However, the red leaf poplar varieties such as 'full red poplar', 'beautiful red poplar' and the like are deepened along with the red color system of the leaves, the color of the leaves becomes more bright and beautiful, and the growth speed of seedlings is gradually reduced. Along with the increase of the construction strength of urban gardens, roads and greening, the red-leaf poplar variety is a few colorful-leaf arbor tree species, and can bring greater economic benefits for production users due to unique color and rich leaf color, and multiple functions of greening, colorizing and purifying.
The middle red poplar has certain cold resistance and barren resistance as the black populus deltoides, but the cold resistance and barren resistance of the red leaf poplar varieties with more prominent leaf colors, such as the whole red poplar, the beautiful red poplar and the like, have obvious descending trend, so that the root of the seedling is more limited by the region of China in the cultivation and planting stage, and the initial planting is more limited; in addition, some seedlings are planted in half an adult period, so that labor is consumed in the operation processes of seedling lifting and the like, the time consumed by manual independent digging is too long, and in addition, in the traditional planting activities, means are too conservative, so that the better growth of red-leaf poplar varieties is not facilitated.
Therefore, we propose a seedling raising device for red-leaf poplar varieties to solve the above problems.
