How long does it take for asparagus to grow?

Introduction to Growing Asparagus

Asparagus is not tolerant to moisture. If the soil is waterlogged and lacks oxygen, it will cause bulb rot. Its absorbing roots are weakly developed. If the water supply is insufficient, it will affect the growth of the plant, especially during the harvest period. If there is insufficient water, the tender stems will be few and thin and easy to age.

The main producing areas of asparagus are China, Peru, Germany, France, Spain, the United States and Japan. Currently, China is the largest producer of asparagus, far ahead of other countries.

Asparagus growth cycle

Although asparagus has a wide adaptability to soil and can be grown in all kinds of soil, it grows best in loose, breathable, well-drained sandy loam rich in organic matter. During the cultivation process, nitrogen fertilizer should be applied in time with the growth of the plant in combination with phosphorus and potassium fertilizers.

Asparagus is a perennial plant. Its life cycle is usually the entire process from seed germination to plant aging, which is generally 8-12 years.

Asparagus growth rate

The life cycle of asparagus can be divided into seedling stage, low-age stage, high-yield stage and senescence stage. The seedling stage is from seed germination to before transplanting, the low-age stage is from transplanting to 2-3 years after harvesting, and the high-yield stage is the period of most vigorous growth. After the high-yield stage, the plant gradually enters the senescence stage.

The growth rate of asparagus is also directly related to the light conditions. The difference between green asparagus without soil and white asparagus with soil lies in the amount of light they receive. The ones that receive more light grow faster.

Asparagus growth cycle management

The normal yield of asparagus per mu is about 4,000 to 6,000 jin. Usually, asparagus is in its peak production period within four to ten years after planting, after which the yield will gradually decline.

Temperature Management

Asparagus has a wide adaptability and is both cold-resistant and heat-resistant. The suitable temperature for seed germination is 25℃~30℃, and the suitable temperature for the growth of tender stems is 15℃~22℃. Within this temperature range, the product quality is good, and the higher the temperature, the faster it grows.

Fertilization management

Asparagus is mostly cultivated in sandy soil, and it is necessary to apply compost to the sandy soil. Secondly, in soil with some clay, the soil structure can be improved by applying compost year by year.
