<h1 class="pgc-h-arrow-right" data-track="1" > asparagus is a perennial plant native to the eastern shores of the Mediterranean and introduced to China in the 20th century, and is now cultivated in countries around the world. Asparagus is a high-grade and precious vegetable, known as one of the world's top ten famous dishes, and is known as the king of vegetables in the world. Asparagus is rich in various vitamins and trace elements, high nutritional prices, generally with young stems for consumption, its meat is tender, delicious, tender and refreshing, whether it is fried, stewed, boiled or cold mixed is very delicious. Now the planting area of asparagus is getting wider and wider, the market demand is increasing, and there are many people who want to grow asparagus. So what kind of growth is required for planting asparagus? as well as planting and management methods. The following small editor simply shared the following:</h1>
Asparagus growing environment
Asparagus is not strict on the growth of the environment, both low temperature resistance, but also high temperature resistance, in our southern climate can grow normally, in cold areas as long as the antifreeze settings can also be safely overwintered, the most suitable growth temperature range of 15-30 °C, below 5 °C or above 36 °C will grow to stop or be inhibited. Asparagus is a light-loving crop that requires strong light and long sunshine, preferably more than 10 hours a day. Asparagus is a waterlogging-resistant plant, for moisture, should be kept moist, especially in the harvest of sufficient water, but also can not be wet or waterlogged, if the field water is too much, there will be root rot. Therefore, when managing asparagus, we must control the water, do not let the field wet or water, and do not let the soil be too dry. For the soil, the requirements of fertile, loose, breathable land, asparagus belongs to the rhizome developed, is a deep rhizome vegetable, only in this place cultivation can achieve its yield, the PH value of the soil is controlled at about 6.5.
How is it grown?
(1) Germination; when planting asparagus, the seed must first germinate, because the seed shell of the asparagus is very hard, and the germination is very slow and the germination rate is low if it is directly sown. So to soak the seeds, put the seeds in 25-30 ° C water for about 3 days, wrap them in moist gauze, and after a week the seeds will grow white buds and you can sow seeds.
(2) Sowing seedlings; seedlings are bred immediately after the seeds sprout, and the seedlings can choose a disposable seedling cup, insert a few holes in the bottom of the cup, and load them into the fire ash soil. Then sow the seeds into the soil, one seed per cup, 2 cm deep, water once until the soil is moist, grow seedlings 5-7 days after sowing, see dry and wet during seedlings, and when asparagus seedlings grow to 15 cm tall, they can be transplanted.
(3) Transplanting; transplanting is generally carried out in the spring and summer seasons, ploughing the field in advance more than a month before transplanting, opening a ditch, ditch depth of 40 cm, ditch width of 30 cm, ploughing deep ploughing in advance to open the ditch, can use the sun's light to kill the original pathogens contained in the soil, insect eggs, etc., but also to achieve soil loosening and ventilation and increase soil fertilizer, which is conducive to future crops to take root and strong stems. Then apply enough organic fertilizer at the bottom of the ditch "is to rot the soil of the soil manure, compost", asparagus harvest for ten years, so try to apply more organic fertilizer, and then fill the original soil back, the asparagus seedlings transplanted and colonized, the colonization density row spacing of 1.2 meters, the plant spacing of 40 cm, after colonization, watering once water penetration is OK.
Daily water and fertilizer management
Asparagus is a perennial plant, planted once can be harvested for more than ten years, the first year is basically management-based no yield, generally in the second and third year to start to increase production. Therefore, the most important thing after colonization is to cultivate and weed, water, fertilize and manage in daily life. Asparagus should be fertilized 4 times a year, starting in the spring until before winter, it can also be applied according to the harvesting and growth, the fertilizer is flushed with nitrogen, phosphorus, potassium compound fertilizer and decomposed manure water, and every 30 kg of compound fertilizer and 10 kg of urea is washed and cooked manure 1500 kg of watering. Do a good job of drainage in the rainy season to prevent water or moisture in the ground area, and water more in dry weather, and maintain. The soil is moist. For some farmers with little planting, if they have animal feces and urine at home, they will be applied every 20 days without using scientific fertilizers, and the yield is quite good. Note that when using animal manure, it must be fermented and decomposed before it can be used, and it must not be poured with uncorried fermented animal manure.
Summary; the above content is about the environmental requirements for asparagus growth, as well as planting and daily water and fertilizer management, this content is for reference only. I hope my sharing will be helpful to everyone. Thanks for reading!
