1, asparagus seedling time: asparagus open ground seedling can be sown in early April to early August, small arched greenhouse seedling can be advanced in early March. Asparagus nursery should choose fertile soil, good permeability, good drainage and irrigation conditions of sandy soil, to choose less weeds, especially perennial weeds less plots.

2, asparagus seed treatment: asparagus seed skin is thick, there is a thick layer of wax, not easy to absorb water, must be soaked to promote germination, pharmaceutical treatment before sowing. Before sowing with 25 ~ 30 ℃ of warm water soak 3 ~ 5 days, change the water 1 ~ 2 times a day, to be the seeds to absorb enough water to fish, mixed with fine sand, mounted in containers, covered with a wet towel, placed in 25 ~ 30 ℃ under the condition of germination, turning 2 times a day, 5 ~ 8 days after the dew white can be sown.

3, asparagus seed sowing: asparagus seedling transplantation is the most commonly used method of production, to facilitate the careful management of the seedling period, a high seedling rate, less seed, can shorten the field of the roots and plants to raise the period, is conducive to improving land utilization. Usually to be about 10% of the seed germination can be sown, sowing before the nursery land to apply sufficient basal fertilizer, do 1.1 m wide flat bed, take the way of granular sowing, sowing depth according to the temperature, sowing density of 10 × 10 cm.

4, asparagus planting technology: asparagus planting before deep tilling and leveling of the land, according to the 1.5 m row spacing open north-south ditch, ditch width 40 cm, 40 cm deep, ditch per acre of high-quality organic fertilizer 5000 kilograms of nitrogen, phosphorus and potassium composite fertilizer 50 kilograms, mixed with the soil, the planting of the ditch should be watered to sink. Planting time is generally in early May, when the age of asparagus seedlings up to 60 ~ 70 days, with 4 ~ 5 strong seedlings, plant height 15 ~ 20 cm can be transplanted planting, planting row spacing of 150 ~ 160 cm, plant spacing of 35 ~ 40 cm.
