Skills of safe overwintering of autumn cabbage

Autumn spinach is an overwintering vegetable sown in autumn and harvested in spring. Generally, it begins to overwinter at the end of November and returns to green at the beginning of March of the next year. The time is more than 100 days. Therefore, under long-term low temperature conditions, how to ensure spinach safe overwintering is the key to high yield. So how should winter spinach be managed? Let's get to know each other.

1. Pour frozen water

Autumn wave vegetables irrigation frozen water must be done "certain","two appropriate", must be based on the water content of the soil to decide whether to irrigate frozen water, generally sandy loam water content is less than 15%, loam is less than 17%, clay is less than 20% should be irrigated frozen water. The second is to irrigate the frozen water in a timely manner. The time of irrigating the frozen water should be when the soil tillage layer can thaw during the day and when there is freezing at night. The right amount of watering should also mean that the frozen water quantity should not be too much and the fire is too little, so as to connect the soil moisture.

2. Apply winter fertilizer

Application of overwintering fertilizer can increase soil nutrient content, play a role in winter fertilizer and spring use, and promote weak to strong, especially for vegetable fields with less base fertilizer, poor soil fertility and weak seedling condition. Therefore, it is necessary to apply winter fertilizer in combination with pouring frozen water. Generally, urea 10 kg or ammonium sulfate 20 kg per mu is applied, and topdressing with water.

3. Cover cold

The cold weather in the northern region is extremely unfavorable for spinach seedlings during winter, so measures should be taken to protect the mulch from cold, increase the ground temperature, and ensure the safety of seedlings. Covering can be carried out after the tillage layer soil is completely frozen, and the covering material can be farm fertilizer rich in organic matter and crushed, and about 1000 kg can be scattered per mu.

The above is an introduction to the safe wintering skills of autumn wave vegetables. I hope it can help you. If you want to know more about it, please pay attention to us.
