Preventive measures for Frost injury of Pepper seedlings

Pepper is a common seasoning vegetable, which is inseparable from it in our daily life, and it can be planted throughout the year through greenhouse technology, but a little cold wind in the process of raising seedlings may cause freezing injury and seriously affect the planting efficiency. So how to prevent the freezing injury of pepper seedlings? Let's get to know it with the editor.

1. Improve the method of raising seedlings.

The traditional seedling raising method is very easy to freeze in the process of ventilation, so we can use the method of temperature control, such as electric hotbed and factory seedling, which is an effective measure to solve the problem of seedling freezing. In artificial breeding, pepper seeds can be soaked in culture bacteria solution to raise seedlings, which can obviously improve seed germination rate, and culture bacteria liquid can also produce biological enzymes and some nutrients can effectively improve the quality of seedlings and improve the cold resistance of seedlings.

2. Enhance the cold resistance of seedlings.

It can contact the mulch as soon as possible before the cold current in winter, let the seedlings receive more light training, spray bacterial liquid during irrigation, improve the photosynthesis of seedling leaves, promote the root system of seedlings, and improve their cold resistance and disease resistance. In the cold weather of rain and snow, make the best use of the gap between sunny days to remove the grass, so that the pepper seedlings can be exposed to the sun. If it suddenly clears up after the rain, you can cover several grass trees on the seedling bed at intervals around noon to prevent the seedlings from losing water and wilting. When the humidity of the seedling bed is high, the seedlings are easily frozen, so watering should be controlled before the cold spell comes. when the bed soil is too wet, plant ash can be applied to absorb moisture.

3. Balanced fertilization

Fertilization in the seedling stage can also improve cold resistance, but if improper fertilization will cause excessive growth of seedlings, resulting in weak stems, poor cold resistance, so fertilization must be balanced. In the seedling stage, we can increase the application of phosphorus and potassium fertilizer and use cold resistance, which can obviously enhance the cold resistance of seedlings and improve the photosynthesis of leaves. The bacterial liquid can be sprayed every other week in the 3-4 leaf stage to enhance the resistance, generally spraying twice.

4. Heat preservation and anti-freezing

In the cold wave period to closely cover the seedbed, in a short period of ventilation, to prevent cold air blowing directly into the seedbed, so as not to hurt seedlings. Cover the straw curtain at night, or scatter the straw on the seedlings and remove it after the cold wave. The grass covered on the seedling bed should be dry. After the snow stops snowing, the snow should be removed from the seedbed in time so as not to cause water in the seedbed after melting.
