Environmental Requirements for Asparagus Cultivation

Asparagus is the seedling of herbaceous plant asparagus, which is used as a vegetable in our life. Asparagus is rich in vitamins and trace elements, as well as many amino acids for human growth. Asparagus is a vegetable with high nutritional value. Now the planting area of asparagus is getting wider and wider, the market value is getting higher and higher, and many people want to start growing asparagus. But growing asparagus requires a certain environment, and today the editor has brought you the environment needed to grow asparagus.

1. Temperature

Asparagus is not very high temperature requirements, can withstand low temperature, but also relatively resistant to high temperature, in a variety of climatic zones can grow normally. But 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 of asparagus germination should not be lower than 5 degrees, and the most suitable temperature is about 28 degrees. If the temperature is higher than 30 degrees, it will reduce the germination rate of asparagus. When the temperature is higher than 35 degrees, the growth of the plant will be significantly inhibited. Reduce the photosynthetic capacity of the plant, resulting in insufficient accumulation of photosynthetic matter, serious withering, asparagus has the strongest photosynthetic capacity when the temperature is about 18 degrees.

2. Lighting

Asparagus in the growth process is very fond of light, the demand for light is very large, can adapt to strong light, long-term light. If the light is not enough, the growth of asparagus is blocked, resulting in sparse branches and leaves, and asparagus is short and unnutritious. And the light changes with the change of the weather, which is closely related to the temperature. Although the light is sufficient when the temperature is too high, it is not conducive to the growth of the plant. The temperature is too low and the light is insufficient, the branches and leaves can not carry out photosynthesis, resulting in the growth of the plant without sufficient photosynthetic matter, seriously reducing the yield.

3. Moisture

Asparagus has strong water retention capacity, less water evaporation, and well-developed roots have a good water absorption capacity, so it is a relatively drought-tolerant crop. However, the phenomenon of water shortage can not occur during the bamboo shoot picking period to ensure that the soil is in a moist state. If the excessive lack of water, it will lead to asparagus thin, growth buds gradually disappear, reducing the yield. However, asparagus is also a very waterlogged vegetable, too much water in the field will cause retting root rot. Therefore, when planting asparagus, we must do a good job in water management, never let too much water in the field, nor can we let the soil be too dry, which will affect the growth of asparagus.

4. Soil

Asparagus has well-developed roots and is a deep-rooted vegetable. Therefore, when choosing to plant soil, we should choose the soil with fertile soil, loose and deep soil, less loss and strong permeability. Planting soil should not be too alkaline, if it is too alkaline, the root will stop developing and begin to shrink, and the plants on the ground will gradually die. Although asparagus has strong adaptability to soil acidity and alkalinity, it is best to control the soil PH value at about 6.5. This is the best soil for asparagus to grow.

These are the requirements of the environment for planting asparagus. Asparagus is a seedling, so it is relatively fragile. Mechanical damage must be prevented in the process of planting. And we need to pay attention to the water, water in the cultivation of asparagus is more troublesome, not only to maintain the water needed for growth, but also to prevent waterlogging.
