Fertilization Time and Amount of Cabbage

Chinese cabbage is a native vegetable in China, which has a long history of cultivation. Next, I would like to introduce the fertilization time and amount of Chinese cabbage.

1. Fertilization time for cabbage

At the seedling stage, Chinese cabbage needs the least amount of fertilizer, but it also needs to ensure adequate nutrition to ensure the growth of Chinese cabbage. After entering the rosette after the seedling stage, the demand for nutrition increases rapidly, and the degree of nutrition at this time will determine the final quality and yield of the cabbage. The final heading period requires no less fertilizer than the rosette period, mainly potash fertilizer and appropriate amount of nitrogen fertilizer.

Second, the amount of fertilizer applied to Chinese cabbage

1. Base fertilizer

The amount of fertilizer applied to one mu of land is about 5000 kg of high-quality mature farm manure and 40-50 kg of compound fertilizer.

two。 Raising seedling fertilizer

The effect of base fertilizer is relatively slow, a small amount of available nitrogen fertilizer should be applied as seedling fertilizer at seedling stage, at this time, the first interseedling can be carried out, and after interseedling, ammonium sulfate 5-8 kg per mu can be applied to promote seedling growth.

3. Topdressing

When Chinese cabbage enters the lotus stage, the growth rate and growth are relatively large, and sufficient fertilizer and water supply are needed. High nitrogen fertilizer and a small amount of phosphorus and potassium fertilizer should be applied as soon as possible to meet the nutritional needs of Chinese cabbage. During this period, 15-20 kg urea and 10 kg potassium sulfate per mu were applied and watered two days after fertilization to ensure that the fertilizer could meet the growth requirements of Chinese cabbage.

4. Topdressing

The heading period is the period of economic yield formation of Chinese cabbage, which grows very fast, and it also needs the most water and fertilizer. One-time topdressing can be taken during the heading period, or it can be divided into two stages, focusing on the first time, combined with watering, 15-20 kg of ammonium nitrate per mu and 10-15 kg of potassium sulfate per mu.

Cabbage is the main vegetable in winter and spring in Northeast and North China. Vegetable leaves can be used for stir-frying, raw food, salting and pickling, and the outer layer of vegetable leaves can also be used as feed.
