Asparagus growth profile
Asparagus does not tolerate moisture, if the soil is waterlogged and lack of oxygen, it will cause rotting of the bulbous shoots, it is weak in the development of the absorption root, if the supply of water is insufficient, it will affect the growth of the plant, especially in the harvest period, the lack of water, the young stem occurs less and thin, easy to aging.
The origins of asparagus are mainly China, Peru, Germany, France, Spain, the United States and Japan, China is currently the largest producer of asparagus, far ahead of other countries.
Asparagus growth cycle
Asparagus, although the adaptability of the soil is wide, a variety of soils can be planted, but in the loose, breathable, well-drained, organic matter-rich sandy loam soil grows well, in the process of cultivation should be with the growth of the plant at the right time with the timely application of nitrogen fertilizer with the application of phosphorus, potassium fertilizer.
Asparagus is a perennial plant, it is a life growth cycle is usually from seed germination to plant senescence of the whole process, generally 8-12 years.
Asparagus growth rate
The life cycle of asparagus can be divided into seedling period, young, productive and senescence, seedling period is from seed germination to planting, planting to harvest 2-3 years for the young period, productive period is the most vigorous period of growth, after the productive period of prosperity, the plant gradually enter the senescence period.
The speed of growth 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, and the growth rate of light is fast.
Management of asparagus growth cycle
The normal yield of asparagus is about 4,000 to 6,000 kilograms per mu. Usually, asparagus is in full production in four to ten years after planting, and then the yield will gradually decline.
Temperature management
Asparagus is widely adapted, both cold and heat, its seed germination temperature for 25 ℃ ~ 30 ℃, the growth of young stems for 15 ℃ ~ 22 ℃, the product quality is good, and the higher the temperature the faster the growth.
Fertilizer management
Asparagus is mostly cultivated in sandy ground, and it is necessary to apply compost in sandy ground, and secondly, in the soil with some clay soil, the soil structure can be improved by applying compost year by year.
