Scientific knowledge of planting garlic seedlings

Soil: it is necessary to select the soil with fertile, sufficient water and no diseases and insect pests in the previous crops, turn the soil deeply and expose it to the sun, and then apply sufficient base fertilizer. Soak seeds to promote germination: select good seeds and soak them in water for about 3 days and change water every day. Sowing: generally sowing at a temperature of about 18 ℃, cover the soil to the tip of garlic after sowing, and then pour enough water to fix the root. Late management: timely watering after seedling emergence, timely topdressing and timely harvest according to its growth and soil fertility.

I. planting conditions

Garlic seedlings are suitable for planting in soils with sufficient water sources, fertile soil and no diseases and insect pests in the previous crops. After selecting a good site, the soil will be ploughed for exposure and disinfection, and then sufficient fertilizer must be applied, because garlic seedlings have higher requirements for nutrition, and there is a greater demand for fertilizer in the process of their growth, so soil fertility must be improved before planting. After fertilization, the base fertilizer and soil are mixed evenly, and then the soil is prepared.

Second, soaking seeds to accelerate germination

Good seeds must be selected before planting in order to increase the yield. First of all, the rotten and cut seeds are selected and removed, and the remaining good seeds are classified according to size. Then soak the seeds in water for about 3 days and change the water every other day, so that the seeds can absorb enough water and help to improve the germination rate. Before sowing, the seeds can be mixed with calcium superphosphate to provide the phosphorus needed for the seeds.

Third, sowing seeds

The sowing time of garlic seedlings is limited, and the general sowing time will choose the temperature of about 18 ℃. Make the bed before sowing, which can not only control the sowing density of garlic seedlings, but also facilitate the management in the later stage. According to the specific planting area to control the number of sowing, should not be too dense planting, sowing garlic seeds should be placed neatly, after sowing, cover the soil, cover to the tip on it, which is conducive to the late seedling.

IV. Post-management

After sowing, we must pour enough water to fix the root, which is beneficial to the germination and emergence of seeds. Watering should be carried out in time after emergence, which is conducive to the growth of the seedlings, and the soil should be moist at any time to prevent the soil from drying and affecting the respiration of the roots. Watering can be combined with soil cultivation, and when the seedlings grow to a certain height, gibberellin can be sprayed appropriately, which can promote the development of stems and leaves. Reasonable topdressing can be carried out according to the growth of garlic seedlings and soil fertility.

5. Timely harvest

Garlic seedling is a kind of vegetable. in order to increase its yield, it can be harvested according to the market demand when the first batch is ripe. It can not only recover part of the cost, but also contribute to the growth of the second batch of seedlings, providing sufficient nutrients and growth space. As the garlic seedlings are reborn on the basis of the roots, do not pull up the garlic seedlings by the roots during harvest, as long as the old leaves are removed in time.
