Three reasons and effects of straw laying on seedling trays

2023-11-06 14:07:03

The first point: Placing a layer of straw at the bottom of the seedling tray can prevent the seedling roots from penetrating the soil, reducing the occurrence of root breakage during movement. If the seedling tray is placed directly on the ground, the root system will extend into the soil from the small holes at the bottom of the tray after it is fully grown in the hole. When the tray is moved, it will break some of the root system and cause root system damage. Placing a layer of straw at the bottom of the seedling tray solves this problem.


The second point is to avoid root contact with the soil, reducing the chances of soil borne disease invasion. Place the seedling tray directly on the ground, and as long as the seedling roots grow out of the hole, there is a chance of contact with the soil. Harmful bacteria in the soil may invade the roots, and having a layer of straw at the bottom eliminates this possibility.


The third point: It can play a role in regulating the environment under the disk. After laying straw under the seedling tray, the permeability of the bottom increases, making it easier for oxygen to enter the substrate. After watering, it is also not easy to form stagnant water at the bottom, which is conducive to root growth. At the same time, it also has the characteristics of fast heating and good moisturizing properties.
