Asparagus planting prospects are good.

Because of the high nutritional value of asparagus, not only the domestic market demand is great, foreign demand for asparagus is also great. At present, China's asparagus planting area, or far from meeting market demand.

And at present the price of asparagus on the ordinary vegetables compared to the price is still belong to the higher, especially the asparagus after deep processing price is to enhance the obvious. So, if growers plant asparagus, and can carry out asparagus raw processing, the market prospect is still very good.

Asparagus is the asparagus family asparagus perennial herbaceous plants stone Diao cypress seedlings, can be vegetables. The white color is called white asparagus, and the green color is called green asparagus when it comes out of the ground. Even though the production regions are different, no matter which asparagus varieties, they become green asparagus when exposed to sunlight, and burying them in the soil or shading them from sunlight will give them a whitish color.

Asparagus planting environment

1, temperature

Asparagus is very adaptable to the temperature, both cold and heat, from the frigid zone to the subtropical zone can be cultivated, but is more suitable for the four seasons, the climate of the temperate zone of cultivation.

In the alpine zone, the temperature -33 ℃, permafrost thickness of 1 meter, can still be safe overwintering, low yield, but better quality. Asparagus seed germination start temperature of 5 ℃, the appropriate temperature of 25-30 ℃, higher than 30 ℃, germination rate, germination potential decreased significantly.

2, soil

Asparagus is suitable for sandy loam soil rich in organic matter, loose soil, deep soil, fertilizer, water, good permeability of fertile soil, good growth.

Asparagus can tolerate mild salinity, but when the soil salinity exceeds 0.2%, the plant development will be obviously affected, the absorbing roots will shrink, the stems and leaves will be weak, and gradually die. Asparagus has strong adaptability to soil acidity and alkalinity, and any soil with pH 5.5-7.8 can be cultivated, and pH 6-6.7 is more suitable.

3, water

Asparagus transpiration is small, the root system is developed, relatively drought-resistant. However, too much drought in the period of harvesting bamboo shoots, will inevitably lead to tender stems weak, growth buds retraction, serious reduction in yield. Asparagus is extremely intolerant of waterlogging, water will lead to root rot and death, so planting plots should be high and dry, pay attention to drainage during the rainy season.
