Fertilize the entire plot. The nursery should be selected with sandy loam soil and sufficient base fertilizer. Drill along the length of the furrow, with a spacing of 40-45 centimeters and a depth of 2-3 centimeters. Apply fully decomposed farmyard manure in the ditch.

Sow and interplant. To promote the germination of asparagus seeds, a new high fat film can be used to mix the seeds, which can keep warm, moisturize, and swell, increase the germination rate of the seeds, and make the seedlings robust. Drive away underground pests and isolate virus infections. It can also be mixed with seed coating agents. After sowing the seeds, slightly suppress them, then cover them with loose soil 2-3 centimeters thick, and then cover them with a layer of grass. Before emergence, water the seedlings in a timely manner to keep the bed soil moist. After emergence, immediately remove the grass. After the seedlings are fully grown, they are interbedded and sprayed with a new high lipid film to form a polymer film to isolate diseases and pests.

Fertilizer and water management. When the seedlings are green, dilute them with fully decomposed human manure and water. But the last topdressing should be done about 2 months before frost, so that the seedlings can fully accumulate assimilated nutrients and cultivate strong seedlings in the later stage of growth. When the rhizome expands, timely spray the underground fruit Zhuangdiling to improve the absorption capacity and expansion vitality of the underground fruit, and promote the development speed. Do a good job in drainage and irrigation, and cultivate soil appropriately.
