(1) Seeding Seedlings Asparagus can be broadcasted on the fly, but seedlings are transplanted with less seed, high emergence rate, and easy management. The asparagus seed coat is thick and hard, so it must be soaked before planting. The method is to soak seeds in warm water of 30°C-40°C for 2 days, change the water for 1-2 times a day. After the seeds are sucked with enough water, the seeds are gauzed with gauze, and sowed until the dew. There are spring sowing and autumn sowing in the south. Generally, 0.75 kg - 1 kg are used for the seedbed of the mu, and 25,000 - 30 thousand seedlings are fertile, for 15 mu - 20 mu. (B) Colonization and cultivation of asparagus once planted for many years of harvest, should be selected to fill the base fertilizer. The south can be planted in the spring and autumn or autumn and nursery in the spring. The depth of colonization is preferably 15 cm from the surface of the underground stem. After the seedlings have survived, they are earth-covered once every 15 days. Each time they are 4 cm to 5 cm thick, the thickness of the cultivated white asparagus is 40 cm. (III) Field management (1) Management of asparagus planting in summer In the spring, nursery plants and asparagus planted in the summer are harvested in the third year. The field management is divided into the second year after the management and planting in the year after planting. After plant survival, it should be done around the development of accelerated clusters to form larger plants. In winter, it enters the hibernation period and is poured over the winter water. After the ground is completely dried up, the dried stems are cut off and the fields are cleaned. In the second year after planting, in the springtime, the fertilizer and water management shall be strengthened to prevent and control pests and diseases. Dwarf stems must not be harvested in a timely manner to promote the lush growth of the plants. (2) The management of asparagus planting in late autumn and early spring Watering and fertilizing will be carried out timely after spring emergence, and soil will be buried continuously with the growth of the seedlings, so that the underground stems will be buried in the soil about 16 centimeters. After 2-3 applications in the summer, after entering the autumn, the plants enter the stage of autumn growth, continue to top-dressing, promote vigorous foliage, accumulate more nutrients, and lay a foundation for the next year's growth. When the new stems grow up to 1 meter to 1.2 meters in length, they are topping to make the stems thick, prevent lodging, and promote photosynthesis. China Agricultural Network Editor
