Turf verti-Drain measure that can not be ignored？

After the lawn is built, in addition to reasonable fertilization, irrigation, pruning and other maintenance management, it is also necessary to punch holes in a timely manner. From the needs of the growth and development of turfgrass and the function of turfgrass, verti-Drain measures are very important. Hole verti-Drain is a process of digging out soil rolls from the lawn at the right time by selecting the appropriate verti-Drain machinery to improve the physical properties and other characteristics of the lawn, so as to accelerate the decomposition of the lawn turnip layer and promote the growth and development of the ground and underground parts of the lawn. Kind of conservation measures. Choosing high-quality grass species from Bright Grass Industry can effectively improve the adversity resistance of the lawn.

1. There are many turf verti-Drain, and there are two main types that are usually used: one is a circular motion punching machine, and the other is a vertical motion punching machine. The vertical movement punching machine has hollow tines, which causes little damage to the surface of the lawn when it works, and the depth of the hole is large, up to 8-10 cm, and it has both forward and vertical verti-Drain methods. The rotary machine has an open shovel-type hollow tine, which has the advantages of fast working speed and less damage to the lawn surface, but the verti-Drain depth is shallower than that of the vertical movement type verti-Drain machine. According to the size of the tines and trowels of the two kinds of punches, the diameter of the soil rolls produced varies between 6-8 mm. The vertical height of the soil rolls also varies with the compactness of the soil, soil bulk density and moisture content, and the impact of soil rolls. The penetrating ability of the hole machine varies. Generally, the tighter the soil, the larger the soil capacity, the lower the water content, and the deeper the hole. The greater the punching capacity of the punch, the deeper the punch. The main function of perforating is to improve the air permeability of the soil. After the soil rolls were unearthed, although the air permeability of the soil between the holes, the parts below the holes, around the holes and the bottom of the holes has not been improved, a series of small holes are left on the soil surface, which increases the rough surface of the soil and expands. The surface area of the soil is reduced, so the air and water permeability of the soil are greatly improved.

2. A lot of turf verti-Drain. After verti-Drain, it is beneficial to release harmful gases in the soil, which is beneficial to improve the wetting characteristics of soil or hydrophobic soil, accelerate the drying of long-term moist soil, and improve the surface compaction or the layer of turnips. The infiltration capacity of thick soil promotes the growth of roots in the hole after the soil roll is unearthed, improves the soil cation exchange capacity, improves the soil's retention of nutrients and water, and accelerates the decomposition rate of organic residues.

3. The turf verti-Drain t after the verti-Drain operation temporarily destroys the integrity of the lawn surface, and the exposed turf soil layer will cause partial dehydration of the lawn grass. When the conditions are suitable for the germination of weed seeds, some weeds are often produced, which accelerates the damage of cutworms and other pests. For very compact lawn soil, as long as the moisture is not limited, verti-Drain can improve the growth conditions near the hole. If the holes are repeatedly drilled for several years, the growth conditions of the entire lawn will be improved.

Verti-Drain time is very important. Under drought conditions, severe local dehydration of turfgrass will occur. For example, in the midsummer, when the hole is drilled during the hot and dry day, the stolon bentgrass lawn will cause severe dehydration. Therefore, it is more appropriate to perforate when the lawn grows luxuriantly and the growth conditions are good. Punching should not only pay attention to time, but also work closely with other measures. For example, surface fertilization and irrigation are carried out immediately after verti-Drain holes, which can effectively prevent the dehydration of lawn grass and increase the utilization rate of fertilizer by the roots.

Because perforation enlarges the surface area of lawn soil, it can generally be more than doubled, thereby increasing the contact area of lawn soil with air and moisture, improving soil water absorption and permeability and soil aeration, which is conducive to the reproduction of aerobic microorganisms. It increases the effective oxygen content of the soil, improves the ability of the soil to release oxygen content, and accelerates the decomposition rate of the ground turnip layer and other organic residues.

After verti-Drain, a series of small holes will be left on the surface of the lawn. However, due to trampling, irrigation, and lateral soil flow, the holes will be filled quickly, thus shortening the period of time for the verti-Drain to function. In order to improve the effect of punching, it is usually necessary to surface soil after punching to clean the soil rolls. Use materials other than lawn soil, such as sand and nutrient soil, for surface application. When these substances fill the holes, the air permeability of the soil is still very good, and it is also beneficial to the decomposition of the turnip layer. If the surface-applied material is fertilizer, it can improve the horizontal and vertical mobility of highly immobile fertilizers such as lime and phosphorus in the soil, speed up the dissolution rate of the fertilizer in the soil, improve the quick-acting effect of the fertilizer, and prevent the volatilization loss of nitrogen fertilizer. Performing surface treatment after verti-Drain is beneficial to both. In addition, the perforated soil rolls must be cleaned to prevent the soil rolls from sticking to the lawn grass after watering, which will affect the landscape and easily cause diseases and weeds.
