Method for integrating punching and fertilization of border trees

Abstract

The invention relates to a method for integrating punching and fertilization of border trees. The method comprises the following steps of: (1) carrying out symmetrical punching in a part with a distance which is not less than 0.5m from a plant trunk, wherein the punching depth is 60-70cm; when the depth of a soil layer is not enough, punching a soil layer, wherein the punching quantity is that 3 holes are respectively punched at each of two sides of the border trees with the diameter at breast height, which is not less than 10cm; and four holes are punched at each of two sides of the border trees with the diameter at breast height, which is 10-20cm; when the distance of the border trees is small, overlapping punching regions; in a fertilization process, commonly sharing one set of the holes between the two border trees; when one hole is additionally increased when the diameter at breast height of the trees with the diameter at breast height which is more than 20cm is increased for 10cm, uniformly distributing the holes, wherein a punching manner adopts punching in a parallel direction of a road or punching in a vertical direction or radial punching consistent to root distribution; and step (2) applying a fertilizer or a soil improvement substance on punching positions of the step (1). According to the method disclosed by the invention, loosened soil and fertilization depth meet the distribution requirements of plant roots and the method has certain acceleration effect on the gas permeability of soil of the roots.

Description

technical field [0001] The invention belongs to the fields of soil science, gardening and forestry, and in particular relates to an integrated method for perforating and fertilizing street trees. Background technique [0002] At home and abroad, with the growth of trees, the soil of street trees is trampled by humans, and the soil becomes more and more compacted, resulting in poor permeability, poor water and nutrient absorption, and poorer fertility, which cannot meet the normal growth of trees. The phenomenon of premature aging and death, especially in saline-alkali land, is more prominent. Improving soil structure and improving fertility are the key factors to ensure the normal growth of trees. The object of the present invention is to provide a method for improving soil structure. [0003] In the past, the conventional method was to rely on manual digging and mixing some large-grained substances with good permeability, such as sand, slag, ceramsite and other inorganic s...

Problems solved by technology

[0003] In the past, the conventional method was to rely on manual digging and mixing some large-grained substances with good permeability, such as sand, slag, ceramsite and other inorganic substances and inorganic fertilizers. Organic substances such as peat, medicinal dregs, straw, and cow dung can also be added. Such as organic fertilizer or a mixture of these substances, etc., the amount of fertilization is determined by experience, which is time-consuming and laborious, the operation is not easy, it cannot be scientific and precise, and it is impossible to determine the type and age of fertilization according to the tree species and age. The amount of application, especially for the three-dimensional planting mode of planting hedges or lawns in the middle of street trees, it is necessary to implement these plants after transplanting. In such a specific environment, it is very limited to rely on manpower to complete, with low efficiency and poor safety. , have some damage to the landscape and environment, etc.

Today, when manpower is scarce and labor costs are increasing, a lot of manpower is needed, but the work efficiency has not been improved. Based on this situation, the present invention provides an integrated method of mechanical punching and intelligent fertilization of street trees
