What are the environmental requirements for asparagus cultivation? A detailed explanation of the latest key points
Asparagus is the young shoot of the herbaceous plant Asparagus officinalis, and it serves as a vegetable in our daily lives. Asparagus is rich in vitamins and various trace elements, and it also contains many amino acids needed for human growth, making it a vegetable with very high nutritional value. Now the cultivation area of asparagus is becoming wider and wider, and its market value is getting higher and higher, so many people also want to start growing it. But growing asparagus requires certain environmental conditions. Today, the editor brings you the environment needed for growing asparagus.
1. Temperature
Asparagus does not have very high temperature requirements. It can tolerate low temperatures and is also relatively resistant to high temperatures, and it can grow normally in various climatic zones. However, if you want to grow asparagus with high yield and high quality, you should plant it in a place with four distinct seasons and a warm climate. The temperature for asparagus germination must not be lower than 5°C, and the most suitable temperature is around 28°C. If the temperature is higher than 30°C, the germination rate of asparagus will be reduced. When it is higher than 35°C, the growth of the plant will be noticeably inhibited. This reduces the plant's photosynthetic capacity, leading to insufficient accumulation of photosynthetic substances, and in severe cases it withers. The time when asparagus has the strongest photosynthetic capacity is when the temperature is around 18°C.
2. Light
Asparagus is very fond of light during its growth process and has a very large demand for light. It can adapt to strong light and long periods of illumination. If there is insufficient light, the growth of asparagus is hindered, resulting in sparse branches and leaves, and the asparagus becomes short and lacking in nutrients. In addition, light changes with the weather and is very closely related to temperature. When the temperature is too high, although there is sufficient light, it is not conducive to plant growth. When the temperature is too low and light is insufficient, the branches and leaves cannot carry out photosynthesis, resulting in the plant not having enough photosynthetic substances for growth and severely reducing yield.
3. Water
Asparagus has a strong water-retention capacity, evaporates little water, and has a well-developed root system with good water absorption capacity, making it a relatively drought-tolerant crop. However, during the spear-harvesting period, there must be no water shortage, and the soil must be kept in a moist state. If there is excessive water shortage, asparagus will become thin and weak, the growing buds will gradually disappear, and yield will be reduced. However, asparagus is also a vegetable that is extremely intolerant of waterlogging. If there is too much accumulated water in the field, root rot and decay will occur. Therefore, when growing asparagus, water management must be done well. Absolutely do not let too much water accumulate in the field, and do not let the soil become too dry. These will all affect the growth of asparagus.
4. Soil
The root system of asparagus is very well developed, and it is a deep-rooted vegetable. Therefore, when choosing planting soil, choose soil that is fertile, loose and deep, with little erosion, and strong permeability. The planting soil must not be too alkaline. If it is too alkaline, the roots will stop developing and begin to shrink, and the aboveground plants will be affected and gradually die. Although asparagus has strong adaptability to soil pH, it is best to keep the soil pH at around 6.5. This is the most suitable soil for asparagus growth.
The above are the environmental requirements for growing asparagus. Asparagus is a young shoot, so it is relatively fragile. During the planting process, mechanical damage must be prevented. Also, what everyone needs to pay attention to is water. Water is relatively troublesome in asparagus cultivation, because you must both maintain the water needed for growth and prevent waterlogging damage. That is all for today's introduction.
