1、 Seed taking

Every autumn, from September to October, asparagus bears fruit, and gradually turns from green to red, which is the sign of fruit maturity. You can start seed collection. Put the picked fruits together, wait for fermentation, and choose the seeds with large particles, full and full vitality as a whole. If you can judge whether the mother is healthy or not, it is better to choose the mother with vigorous growth

2、 Sowing time

The seeds of asparagus can be sown in spring and autumn, and each has its own advantages. Planting in autumn is from September to October. The probability of budding is relatively high, but the time is relatively long. You should have a certain patience to manage and cultivate. If you want a short time to facilitate management, you can choose to sow in spring. In this way, you don't need to consider the winter of seedlings, which saves a lot of trouble

3、 Sowing method

1. Select the soil with good drainage and air permeability, level it before sowing, remove large stones, weeds and other impurities, and carry out sterilization treatment

2. Make a horizontal ditch with a depth of 7 cm according to the distance of about 22 cm for sowing. The seed depth is 6 cm, and the adjacent seed pits can be separated by 23 cm. If the amount of seeds is uncertain, it can be considered according to the amount of 20 kg per mu

3. After the seeds are planted, spray water, cover with base fertilizer or plant ash, and then cover with fine soil until it is flush with the ditch surface, and cover with straw mat at the top to reduce the loss of water and temperature

4. Control the temperature at about 18 degrees, watch the dry and wet conditions of the soil, and replenish water in time. In about 20 days, the seeds will grow seedlings. After the seedlings are visible to the naked eye, the straw mat on them will be removed for later management

4、 Later maintenance

1. Shade the seedlings after they come out. You can pull a shading net or put up a shed, or plant other tall crops. At this time, you should keep the soil moist

2. When the seedlings grow to 3 cm, weeds in the field should be removed and fertilizer should be added. The soil should be loosened in autumn. If you don't know what fertilizer to use, you can use farm fertilizer
