In order to overcome the effects of spring or late spring on planting grasses in the spring, some anti-freezing and seedling protection techniques can be used to improve the ecological environment of pasture plantation and create conditions for the growth of forage grass at the seedling stage.
Ditch planting and sowing: In areas where spring is prone to cold springs and winds are relatively large, planting methods using furrow planting can be used to increase the ventilation and light transmission of pasture seeds or seedlings. At the same time, it is also possible to ensure the use of furrow bottom insulation and protection. Herbage plants grow neatly and robustly.
Covering fertilizer and spraying protection agent: Applying organic fertilizer or manure fertilizer on pasture planted grass in the spring can keep the ground temperature relatively stable, reduce the influence of temperature change on seedling growth, and suppress the grassland and spray a new high-fat film. Insulation antifreeze to prevent bacteria infection.
Timely and appropriate irrigation: Irrigation can increase the heat capacity of the soil and keep grassland soil temperature relatively stable, which is conducive to the growth of forage grass and increase the proportion of strong seedlings, thus enhancing the frost resistance of the planted pasture in the spring.
