Asparagus planting method

Ask: asparagus planting method, the more detailed the better, is there any technology available? Asparagus is one of the most efficient cash crops, ranking first among the top ten famous dishes in the world, and enjoys the laudatory name of "king of vegetables" in the international market. Asparagus is rich in albumin and many kinds of amino acids which can inhibit the growth of cancer cells. it is a nutritional tonic for anti-fatigue and physical strength. it has medicinal values such as preventing cancer, anti-cancer, reducing blood lipids and preventing coronary heart disease. therefore, asparagus is in short supply at home and abroad, and the development prospect is very broad. Planting asparagus has become a new economic growth point of planting industry at present, and it is the main content of "three high" agricultural development. At present, the cultivation of asparagus in domestic protected areas has just started, the total area of asparagus cultivation in the greenhouse is less than 20 hectares, and the daily supply during harvest is less than 2000 kg, so the market prospect is promising. The price of asparagus is more than ten times that of other protected vegetables, and one planting can be harvested continuously for more than 20 years, the economic benefit is very amazing. For the cultivation of asparagus in protected areas, winter warm greenhouses are needed in the cold areas of the north, large arch sheds are used in the Huang-Huai River Basin, and bread sheds or small arch sheds are used in the south of the Yangtze River Basin. 1. Asparagus seed selection: asparagus Prince, Grande, Champion, Apollo and other generation hybrids. two。 The time of raising seedlings: asparagus can be raised in open field from March to September in the north, in winter with greenhouse, and in the south. 3. Soak the seeds to promote germination: soak the seeds in warm water of 30-35 ℃ in spring for 2-3 days (soak the seedlings with cold well water in summer and autumn), then cover them with wet towels to accelerate germination, rinse the seeds with clean water twice a day to avoid stuffing seeds, and sow seeds after 10% whitening. 4. Sowing method: select sandy loam soil, sow 20 square meters every 50 grams of seeds, irrigate the bottom water, draw a line according to the row-plant spacing of 10 cm, sow single seed in the center, and cover it with 2 cm thick sifted fine soil. 5. Transplanting: it is better to transplant asparagus from June to July, because the time of field management is short, it can be harvested around the Spring Festival of that year, and the effect is quick. It can also be transplanted to the seedlings of one year, which is large and long-aged, and its yield is higher than that of the seedlings raised in spring in that year. Asparagus in the greenhouse was kept in the east-west direction and transplanted in the north-south direction, with a row spacing of 120 cm and a plant spacing of 25 cm, with 36 plants per row. In order to ensure that bamboo shoots are harvested in winter, fertilizer and water management should be strengthened in summer and autumn. 6. Summer management: in order to accelerate the growth of asparagus, 50 kg compound fertilizer was applied every 667 square meters from mid-July to mid-August, and the management of diseases and insect pests was strengthened in the rainy season. 7. Clear the garden: water it once in November and remove the dry stems from the ground a few days later. 8. Buckle shed: adopt a single slope type arch shed, the north slope is surrounded by corn straw, etc., and the shed is covered with grass. The shed supports a small arch film with a height of 70 centimeters in each row. 9. Harvest: according to the temperature and growth situation, when the bamboo shoot sprouts grow to about 25 cm before the Spring Festival, they will be harvested and listed along the ground. In the first year, the bamboo shoot field was harvested for two months (466 square meters, about 350,400 kilograms), and the rest of the stem (mother stem) continued to grow. From June to July, summer bamboo shoots will be harvested for another two months. With the increase of the age of bamboo shoots, the harvest time should be extended appropriately, but do not overharvest because of the high price.
