Cabbage is actually cabbage and cabbage, also known as rugby and olive dishes. If cabbage is to have high yield and good quality, then the curd should be rolled up. At the same time, the growth of cabbage is inseparable from fertilization, so do you know how to fertilize cabbage?

1. Base fertilizer

Basic fertilizer is generally carried out in conjunction with soil preparation. It is mainly used to improve the structure of the soil, increase the fertility of the soil, so that the planted crops can adapt to the planting environment faster, and play an important role in increasing the survival rate of planting. The basic fertilizer of cabbage is generally carried out within 15 days of planting money. Each acre needs to be applied with 2,000 kg of manure and urine, 25 kg of phosphate fertilizer, and about 100 kg of plant ash or soil mixed manure. Whole and mix well.

2. Seedling fertilizer

Seedling fertilizer is carried out when the cabbage is still in the seedling stage, mainly to promote the growth of the seedlings and increase the resistance of the seedlings, so as to increase the survival rate of the cabbage seedlings after transplanting and planting. Fertilization at the seedling stage is generally carried out with manure and urine, or water mixed with an appropriate amount of ureafor watering, but it should be noted that the concentration of fertilizer at the seedling stage should not be too large, and thin fertilizer should be used as the main to avoid burning seedling.

3. Top dressing during growth

Cabbage enters the growth period after it is planted, and fertilization during the growth period is also very critical. In general, we have to divide the growth fertilizer several times, and follow the principle of diligently applying thin fertilizers. The growth fertilizer is mainly nitrogen fertilizer, which promotes the growth of cabbage plants, makes it enter the rosette stage as soon as possible, and heads as soon as possible, shortens the growth cycle of cabbage, and improves the conversion rate of nutrients. However, during the growth period of cabbage, we also need to properly apply about 15 kilograms of phosphate fertilizer, which is still very helpful to improve the resistance of cabbage.

4. Top dressing in the rosette stage

After the cabbage enters the rosette stage, we must ensure the quality of the lotus plate and promote the growth of the lotus plate. This is still very beneficial to the heading of the cabbage in the later stage. The top dressing in the rosette stage is mainly urea, and the dosage per mu is about 20 kg. However, at this stage, we need to properly apply about ten kilograms of potassium fertilizer, which can promote the differentiation of flower buds and the formation of flower buds and bulbs.

5. Flower ball top dressing

The top dressing during the heading of cabbage generally needs to be divided into three stages, namely the early heading, the middle heading, and the middle and late heading. In the early stage of cabbage heading, each acre generally requires about 30 catties of urea, about 12 to 18 catties of potash fertilizer, and about 5 catties of phosphate fertilizer, which can promote the rapid expansion of the curd and prevent the space of the curd. In the middle heading stage of cabbage, the amount of topdressing of nitrogen fertilizer is 20 catties, potash fertilizer is 10 catties, and phosphate fertilizer is 3 catties, which can improve the yield and quality of the curd. In the middle and late stages of cabbage, generally only proper foliar topdressing is needed.

In the process of planting cabbage, fertilization is generally divided into these five stages, and the fertilization requirements of each stage are also different, so we need to follow the correct fertilization principles, otherwise no amount of fertilizer will be effective .
