Cabbage is one of the favorite vegetables of northern Chinese. Especially in the past, a large amount of cabbage was stored in the cellar every winter to meet the needs of the whole winter. So how to plant cabbage can make cabbage grow better, first from his In terms of fertilizer requirements:

Cabbage  Rule of fertilizer requirement:

The ratio of nutrients required for cabbage during the whole growth period is 1:0.5:1.7.

Seedling stage: sufficient nutrients need to be supplied, and fertilizer absorption accounts for 2.4% of the total growth period;

After entering the rosette period, the growth amount increases sharply. The vigorous growth at this time has a decisive effect on the growth of the leaf ball and the final yield. The amount of fertilizer absorption accounts for 41.8% of the total growth period;

The nodulation period is the period of product organ formation, and fat absorption accounts for 55.8% of the total growth period. Before the rosette period, nitrogen was the main source, followed by potassium, and to the nodulation period, potassium was the main component, and nitrogen was the secondary component.

Cabbage  base fertilizer

1. The purpose of fertilization: In addition to ensuring the nutrient requirements of the plant in the early stage, it can also maintain a strong stamina after the rosette period.

2. Fertilization ratio, dosage and method: organic fertilizer 200kg-300kg/mu + balanced compound fertilizer (15-15-15, 17-17-17, etc. ratio) 40-60kg/mu, organic fertilizer and chemical fertilizer mixed application Enter, ditch in the middle of the planting rows of Chinese cabbage, bury the fertilizer in the ditch, and then cover with soil, so that nutrients are concentrated, the effect is better.

Cabbage  Lifting fertilizer

1. Purpose of fertilization: Promote strong seedlings to emerge early to meet the large demand for nutrients for the rapid growth of cabbage seedlings.

2. Fertilization ratio, dosage and method: after seedlings can be topped up, seedling fertilizer can be applied, high nitrogen compound fertilizer (32-4-4, 26-5-5, etc.) 5-10kg/mu, can be applied according to actual conditions , Spreading and other fertilization methods for top dressing.

Cabbage Fat tree fat (rosette period)

1. The purpose of fertilization: After the cabbage enters the rosette period, a large number of root systems occur, the growth amount increases sharply, and the amount of fertilizer absorption is large. The amount of nutrient supply in this period is directly related to the high yield, and it is also a key period for the future.

2. Fertilization ratio, dosage and method: high nitrogen compound fertilizer (32-4-4, 26-5-5, etc.) 15-20kg/mu, can be applied in hole or ditch.

Cabbage Fattening

1. Purpose of fertilization: This period is the period of product organ formation, which requires a lot of nutrients. It is necessary to pay attention to supplementing potassium and calcium to ensure the normal filling of cabbage and prevent the occurrence of physiological diseases such as dry heart disease.

2. Proportion, amount and method of fertilization: At the beginning of the ball formation period, 30-35 kg of high-nitrogen and high-potassium compound fertilizer (14-5-26, 19-6-22, etc.) can be applied. Top dressing with other fertilization methods; in the middle of the head, a large amount of elemental water-soluble fertilizer (21-21-21) 500-1500 times foliar spray can be used.
