The latest fertilization skills of asparagus

As an evergreen herb for many years, asparagus has a high demand for fertilizer, and only eating enough nutrients can make its growth stronger, but many people do not know how to fertilize asparagus, nor do they know what fertilizer to apply? Let's take a look at the fertilization skills of Wenzhu together with Xiaobian.

1. Fertilization time

Although the demand for fertilizer is relatively large, it is not necessary to fertilize it every day, and the amount of fertilizer is different in each growing season, so pay more attention to the fertilization process. Generally speaking, after spring, asparagus will enter the growth period, when it needs a lot of nutrients to promote its growth, at this time can be fertilized once every half month. After summer, fertilization and harvesting need to be reduced accordingly, because the summer climate is relatively hot, and the growth rate of asparagus is relatively slow, so fertilization should be reduced as much as possible. After autumn, the temperature is cool, and asparagus enters the growing season again, so it is necessary to increase the amount of fertilizer, but it cannot be applied too much, otherwise it will appear the phenomenon of burning roots. In winter, basically do not apply fertilizer.

2. Fertilization method

As a leaf-viewing plant, it is best to fertilize mainly nitrogen fertilizer. Generally, nitrogen fertilizer is diluted by 10-20 times before irrigation. However, in addition to hydroponic culture, granular fertilizer mainly composed of nitrogen, phosphorus and potassium can also be applied. Generally, it is mainly applied in holes, or diluted after irrigation. This is beneficial to the absorption of roots, and can also promote the growth of plants without rotten roots. The slow-release fertilizer on the market contains a certain amount of nitrogen, phosphorus and potassium, and the nutrients are slowly released in the film, and the effect can be as high as four to twelve months after each application. This kind of fertilizer is relatively mild, clean and sanitary, and its release is also related to temperature, so it is very suitable for asparagus, basically a fertilization does not need to be managed.

3. Precautions

Many friends in the process of fertilization, often a fertilizer too thick, especially in the asparagus grow up after the stereotypes, you can properly control the amount and frequency of fertilization. However, in the vigorous growth period, nitrogen and phosphorus fertilizer should be applied 1-2 times a month, and other liquid fertilizers are also available to promote plant growth. In the flowering period of asparagus, fertilization should not be too much, so as not to cause excessive growth and cause premature decline of flowers.
