In which lunar month is cabbage usually planted?

Cabbage is very popular all over the world because of its easy storage, transportation and processing, rich nutritional value and various eating methods. Cabbage is rich in vitamin C, vitamin K, B vitamins, dietary fiber, and minerals such as calcium and potassium. Cabbage, also known as cabbage, cabbage , round cabbage, and cauliflower, etc. Let’s learn together in which month of the lunar calendar cabbage is generally sown?

In which lunar month is cabbage usually planted?

The planting time of cabbage varies from region to region. In cold regions such as the Northeast and Northwest, cabbage can usually only be planted in spring and harvested in summer and autumn. In North China and other northern regions, seedlings are generally raised in spring from February to March, transplanted from March to April, and harvested in summer. In autumn, seeds are usually sown in July and harvested in late autumn to winter. In the southern regions, seedlings can be raised and sown in spring, summer and autumn. When planting cabbage, it is usually necessary to raise seedlings first. When sowing, you can choose a seedbed or a seedling tray, and the specific method can be determined according to the actual situation. Water should be applied before sowing to avoid soil compaction caused by watering after sowing, which will affect seedling emergence. After sowing, the soil should be covered with a thin layer of fine soil, avoid too thick a layer. Before germination, the temperature should be kept between 20-25℃ and the soil should be moist. After the seedlings emerge, the daytime temperature should be maintained at 22-25℃, and should be lowered to 10-15℃ at night, because high temperatures at night can easily cause the seedlings to grow too tall.

Cabbage planting method

1. Cultivate strong seedlings

Before sowing cabbage, mix the seeds with sand and then sow them. The seedbed needs to be watered thoroughly first and covered with a thin layer of soil after sowing. When raising seedlings in winter and spring, the ground film should be covered to maintain the soil temperature and humidity. In summer and autumn, the shade net should be covered and the soil should be kept moist. The covering should be removed in time after the seedlings emerge. During the seedling raising period, the soil should be kept moderately moist and attention should be paid to the prevention and control of diseases and pests.

2. Planting

When the cabbage grows six or seven leaves, it can be transplanted. When planting, bring a large clump of soil to reduce damage to the root system. Apply 5,000 kilograms of farmyard manure and 50 to 60 kilograms of compound fertilizer per mu of land as base fertilizer, and then plant the crops after land preparation. Water immediately after planting to encourage the seedlings to resume growth.

3. Field management

(1) Watering

After the cabbage is planted, if there is drought, water it in time. It usually takes a week for the seedlings to grow. Properly controlling water after the seedlings have grown will help the roots penetrate deeper into the soil. When entering the rosette stage and heading stage, cabbage's water requirement increases, and the soil should be kept moist to facilitate heading. In hot seasons, watering should be done in the morning or evening.

(2) Topdressing

From planting to harvesting, cabbage needs 3 to 4 top dressings, especially after it forms a head and grows rapidly, so it is necessary to ensure sufficient nutrients. When watering after the seedlings have grown, 10 to 15 kilograms of urea can be applied per mu. The second topdressing is carried out in the early stage of rosette, with 30 catties of urea and 10 catties of potassium sulfate applied per mu. Apply the third top dressing in the early stage of heading, using the same fertilizer . If fertilizer deficiency occurs in the middle stage of heading, top dressing should be applied again 15 days before harvest.

(3) Use of trace elements

Cabbage has a high demand for calcium, and when it is deficient in calcium, it is prone to dry heart and rotten leaves. When boron is deficient, the top of the leaf head is poorly developed. In the early stage of heading, chelated calcium and borax solution can be sprayed for 2 to 3 times in a row to prevent boron and calcium deficiency, promote heading, and improve yield and quality.

4. Prevent and control pests and diseases

Common insect pests of cabbage include cabbage worms and diamondback moths, which are more serious in summer and autumn, affecting heading and increasing the risk of soft rot. For prevention and control, you can use highly effective chlorfenapyr and emamectin benzoate, which are insecticides with fast killing speed and long lasting effect. For soft rot, you can use chlorobromoisocyanuric acid, Chunlei·Royal Copper and other agents for spraying prevention and control, focusing on spraying the base of the petiole and the base of the stem.

In summary, although cabbage has strong adaptability, the specific sowing time still needs to be determined according to local climate and planting habits. In addition, early-maturing or late-maturing varieties should be selected according to climatic conditions.
