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 to collect seeds. Put the fruits together, wait for fermentation, and choose the seeds with large particles and full vitality as a whole. If we can judge whether the mother is healthy or not, it is better to choose the one with vigorous growth.
The seeds of tianmendong can be sown in spring and autumn, and each has its own advantages. Autumn is planted in September to October, the probability of sprouting is relatively high, but the time is relatively long, we should have some patience to manage and cultivate, if we want a short time for management, we can choose to sow in spring, so that we don't need to consider the winter problem of seedlings, it's a lot of trouble.
1. Select the soil with good drainage performance and air permeability, level it before sowing, remove impurities such as boulders and weeds, and carry out sterilization treatment..
2. According to the distance of about 22 cm, make a cross ditch with a depth of 7 cm, and sow. The seed depth is 6 cm, and the spacing between adjacent seed pits is 2-3 cm. If you are not sure about the amount of seeds, you can consider the amount of 20 jin per mu
3. After the seeds are planted, spray water, cover with base fertilizer or plant ash, and then cover with soil with fine soil until it is flush with the ditch surface, and cover with straw mat at the top to reduce water and temperature loss.
4. Control the temperature to about 18 degrees, watch the dry and wet conditions of the soil, and make up water in time. About 20 days or so, the seeds will grow seedlings. After the seedlings are visible to the naked eye, the straw mat on the top will be removed for later management.
1. After the seedlings come out, they need to be shaded. You can pull a shade net or build a shed, or you can plant other tall crops. At this time, you still need to keep the soil moist.
2. The seedlings have grown to 3cm, weeds in the field should be removed, fertilizer should be added, and the soil should be loosened in autumn. I don't know what fertilizer to use, just use farmyard manure.
