Fertilization skills of asparagus

Asparagus as an evergreen herb for many years, the demand for fertilizer is relatively high, and only by eating enough nutrients can it grow stronger, but many people do not know how to fertilize asparagus, nor what fertilizer to apply. Let's take a look at the fertilization skills of asparagus with the editor.

1. Fertilization time

Although asparagus has a large demand for fertilizer, it does not have to be fertilized every day, and the amount of fertilizer varies from season to season, so more attention should be paid to it in the process of fertilization. Generally speaking, after spring, asparagus will enter the growth period, when a lot of nutrients are needed to promote its growth, and fertilizer can be applied every half a month. After summer, fertilization harvest needs to be reduced accordingly, because the summer climate is relatively hot, the growth rate of asparagus is relatively slow, so it is necessary to apply less fertilizer as much as possible. After autumn, the temperature is cool and asparagus enters the growing season, so it is necessary to increase the amount of fertilizer, but do not apply too much fertilizer, otherwise there will be root burning phenomenon, basically do not apply fertilizer in winter.

2. Fertilization method

Asparagus, as a foliage plant, should be fertilized mainly with nitrogen fertilizer, which is generally diluted 10-20 times and then poured, but in addition to hydroponic asparagus, granular chemical fertilizer dominated by nitrogen, phosphorus and potassium can also be applied, generally mainly by hole application, and can also be diluted and irrigated. This is conducive to root absorption, but also can promote plant growth, and there will not be root rot phenomenon. The slow-release fertilizers on the market contain 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 12 months at a time. This kind of fertilizer is relatively peaceful, clean and hygienic, and its release is also related to temperature, so it is very suitable for asparagus.

3. Points for attention

In the process of fertilization, many friends often apply too much fertilizer at one time, especially after asparagus grows up and sets, the amount and frequency of fertilizer application can be properly controlled. However, in the period of vigorous growth, nitrogen and phosphorus fertilizer should be applied 1-2 times a month, and other liquid fertilizers can also be used to promote plant growth. In the flowering period of asparagus, do not apply too much fertilizer, so as not to cause overgrowth and cause flowers to decay ahead of time.
