Thousands of trees can be planted in spring and autumn. It is better to load late in spring and mid-April, that is, the survival rate of planting is highest when the upper buds of the seedlings are enlarged and spherical, and planting in autumn should be carried out between the beginning of leaf fall and the beginning of December.
First, dig the tree hole. The size of the tree hole should not be less than 1.2m×1.2m. Too small a tree hole is not conducive to the growth of its root system, and it is also vulnerable to wind damage; the depth of the tree hole should not be less than 80 cm, if the soil does not meet the requirements , It is necessary to carry out guest soil. When planting, first fill in the subsoil and make sure that the base fertilizer is fully mixed with the backfill soil. After the seedlings are placed in the tree hole and straightened, fill the soil twice, and layer by layer, and lift the seedlings gently at the last time, such as the planting ground. The soil is dry and not easy to water. You can bury it deeper, 8 cm to 10 cm. After planting:
The soil is moist, and the moist soil is conducive to the growth of the root system and the restoration of the tree vigor. At the end of autumn, water should be drenched with antifreeze water. In the early spring of the second year, the water should be watered well. During the normal spring dry period in April and May, coupled with the strong spring wind in the north and the long duration, water should be watered once or twice. Water should be drained in time on rainy days in summer to prevent the accumulation of water in the planting hole, which may cause the plant to die due to rotten roots. Pour antifreeze water in late autumn. In the early spring and late autumn of the third year, just pour the green water and anti-freeze water. At other times, it will grow with reliable and natural precipitation without watering. In the fourth year and beyond, it can be managed according to the law.
Thousands of trees are tolerant to barrenness and do not require high fertilizer requirements, but the newly planted seedlings should be given an appropriate amount of fertilizer. The base肥料可以12月omposed and fermented ring fertilizer. After mid-to-late June, the seedlings should be topdressed with a compound fertilizer of nitrogen, phosphorus and potassium, combined with late autumn Pour frozen water and apply cow and horse dung again. The three-element compound fertilizer will be topdressed in the late spring of the following year, and the farmyard manure will be applied in the late fall. For future management, only the farmyard fertilizer will be applied in the late fall. Adequate fertilizer can enhance its resistance to diseases and insects and speed up growth.
Thousand-head chrysanthemum is generally cut dry when planting, and the fixed dry height is 2.5 meters to 3.5 meters. After the planting sprouts, it can be allowed to grow. When pruning in early winter, choose 3 to 5 evenly distributed and vigorous branches on the main trunk as the main branch, thin out the rest, and cut the remaining main branches short, keeping the outer buds on the main branches; Two or three side branches can be kept on the main branch, and the remaining side branches must be thinned out. The remaining side branches must be strong and strong; after the skeleton is formed, only dense branches, dry branches, diseased branches, and hanging branches need to be thinned out every year. Just divide.
