When do cabbage hearts usually be planted? What are the key points of fertilization techniques?

Chinese cabbage, also known as Chinese cabbage, cauliflower, is one of the unique vegetables in southern China, which is now introduced and planted all over the world. Cabbage heart, whether stir-fried or used to cook noodles, is a good match, rich in certain nutrients. In the process of planting Chinese cabbage, fertilizer is usually used to increase yield. let's take a look at when Chinese cabbage is generally planted and the main points of fertilization techniques.

When do cabbage hearts usually be planted?

Although Chinese cabbage can be planted all the year round, it is not due to different climatic environments, so the planting time is also different. if you choose an inappropriate season to grow inappropriate vegetables, it will also make it difficult to survive and grow. Therefore, the planting time is extremely important, generally planted around March in spring or August-September in autumn, when it is common to plant Chinese cabbage, it is also the best period for the growth of Chinese cabbage, and there is a significant increase in yield.

2. Key points of fertilization techniques for Chinese cabbage.

Chinese cabbage is a kind of vegetable with short growth cycle and large growth, which requires adequate supply of fertilizer and water during the whole growth period. In the absorption of the three major nutrient elements, nitrogen is the most, potassium is the second, and phosphorus is the least. Because the edible part is mainly Chinese cabbage (bolting leaves and inflorescences), fertilization needs to ensure adequate vegetative growth in the early stage and the development of Chinese cabbage in the later stage in time, so that the Chinese cabbage can be sturdy and high quality. Therefore, not only need to apply sufficient base fertilizer before sowing, timely and adequate topdressing is also essential.

1. Base fertilizer

Chinese cabbage is a fast-growing vegetable with shallow root, short growth period and high planting density, so it is necessary to apply sufficient basal fertilizer. Generally, 80-100 kg of organic fertilizer and 40 kg of microbial agents are applied per mu to create a good root growth environment and nutritional requirements for the whole growth cycle.

2. Topdressing

Seedling stage: topdressing nitrogen, phosphorus and potassium fertilizer, which is mainly nitrogen fertilizer.

Leaf growth period: topdressing nitrogen, phosphorus and potassium fertilizer, which is dominated by nitrogen fertilizer.

In the later stage of growth, nitrogen, phosphorus and potassium fertilizer was applied as topdressing, and potassium fertilizer was the main fertilizer.

If there is a shortage of organic matter in the soil, organic fertilizer can be added appropriately.

In addition, if there are some symptoms of element deficiency, it is necessary to supplement the corresponding trace element fertilizer.

When the cabbage has 4-5 leaves and the seedling age is 18-22 days, the root system is basically developed and complete. At this time, you can transplant part of the overdense seedlings to the new seedlings, and the plant spacing of the seedlings planted in the new pot can be 3-5 cm. The remaining seedlings also keep the distance between seedlings 3-5 cm, so that the seedlings have sufficient nutritional area to prevent overgrowth. When transplanting, you can use sticks to lift up and transplant with soil. when planting, you should be careful not to hurt the roots, in order to survive and slow seedlings, and water them in time after planting.

Chinese cabbage can be planted year-round, and the characteristics of fertilizer requirement are similar to those of Chinese cabbage. In general, basic fertilizer should be applied according to soil quality and previous fertilizer, and topdressing should be applied at the same time according to the growth situation.
