Today, we continue yesterday’s sharing and continue to take you to understand the basic concepts of lawn maintenance.
Reduce trampling and reduce the concept of physiological endurance limit of stress
Each lawn variety has its own functional quality and appearance quality. These respective attributes constitute the different characteristics of each variety. But no matter what type of lawn, it must have a good living environment and a certain amount of water necessary for the growth process. A soil flat bed with moisture, temperature, light and sufficient nutrients, good permeability and good physical and chemical properties.
However, during the actual growth process of turf grass, it needs to withstand all aspects of trampling and stress. There are high-frequency mechanical operations, manual operations, court operations, as well as watering and rain on the soil leaching and erosion, which will cause the turf lawn to be damaged. The compaction of the bed will cause compaction. As a result, it will inevitably lead to the destruction of the good growth environment of turfgrass. It will greatly reduce the activity of soil microorganisms and increase the accumulation of hay layer. As a result, the hay layer will become thicker and the roots of the lawn will grow in the hay layer.
The wither layer blocks the soil that plays a multiple buffering role for the lawn root system – this huge volume contains and slowly releases water, temperature, heat, nutrients, air, etc., causing the root system to become superficial and the lawn grass to behave poorly. Extreme water shortage, lack of fertilizer, high temperature damage and freezing phenomenon. In rainy weather, extreme water accumulation will occur due to the sponge effect of the hay layer, resulting in poor drainage. This kind of trampling will cause soil compaction The thickening of the withered grass layer is also not conducive to the infiltration of watering, fertilizing and pesticide application, causing the management measures to fail to achieve the expected results. In addition, the withered grass layer also provides a good habitat and refuge for pests and diseases, which is a breeding ground for pests and diseases. and a breeding ground for reproduction. In short, frequent trampling, especially large-scale mechanical operations after rain, is one of the important reasons for poor growth of turfgrass.
Although it can be alleviated by hole drilling, thinning, scratching, puncturing, etc., these improvement processes are also trampling processes. Lawn management is urgent. This requires management workers to minimize trampling on the lawn and reduce rainy days. Operations, especially large-scale machinery operations, reduce the stress on the lawn and allow the lawn to grow in a good environment. It will grow the functional quality and appearance quality that turfgrass should have. Improve the quality of the golf course. The stress on the lawn is also reflected in another aspect. Insufficient understanding of the physiological limits of various lawns to withstand stress. In order to improve the smoothness and compactness of the green, in order to increase the speed of the green, ultra-low cutting and super rolling have caused the soil to be too compact. .The green grass grows thin and is in a state of maintenance. It shows the characteristics of fertilizer deficiency and high-risk morbidity.
In fact, the growth of roots and leaves is directly proportional. The longer the stems and leaves, the more developed the root system of the lawn. On the contrary, the root system of the lawn will be thin. Strong rolling pressure will make the growth of the lawn worse. The root system will grow in a poor environment and shrink. The speed of the green will be increased. But green grass is in danger. This kind of practice of forcing it regardless of species or reasons is not advisable. Different species have different physiological indicators. Scientific maintenance and management plans should be formulated according to their respective physiological characteristics. , for the best results.
