Seedling raising technique of cauliflower

Cauliflower, also known as golden needle, is a perennial herb, its nutritional value is very high. Cauliflower also has various functions such as clearing heat and promoting dampness, eliminating food and eyesight, and so on. And cauliflower is also conducive to postpartum recovery. Now the planting area of cauliflower is also very extensive, so how should we raise seedlings when planting cauliflower? The following editor has brought the seedling technology of cauliflower, let's have a look!

1. Seedbed finishing

Although cauliflower has little demand for soil, it wants to grow high-yield and high-quality cauliflower. Then we still have to choose to plant on the soil with sufficient fertility, high permeability and normal drainage and irrigation. Cauliflower is a perennial vegetable, so we must pay attention to soil preparation before planting. Turning the soil deep into the soil is very helpful to the growth of the roots of cauliflower, keeping the depth at about 25 cm. Then make a stem and make a bed to facilitate planting management. The length of the field border should be controlled according to the actual situation, so as to facilitate planting.

2. Seed propagation

The propagation method of cauliflower is generally based on sowing, and it is also the main method to improve the speed of seedling production. First of all, we need to do a good job of keeping the seeds of cauliflower, and take out the seeds from the plant when the seeds are mature. Because the germination rate of cauliflower seeds is relatively low, we also need to do a good job of seed germination before sowing. Seed soaking in warm water and seed dressing with new high-fat membrane can not only improve the germination rate of seeds, but also enhance the disease resistance of seeds. The propagation of cauliflower also includes cuttage, ramet and so on, which are mainly selected according to the actual situation.

3. Sowing management

Cauliflower sowing method is mainly hole sowing, first of all, we need to control the sowing density and dig a good sowing hole, and remember not to sow too closely to prevent overcrowded growth of seedlings and reduce the survival rate of seedlings. Sow 2-3 seeds in each sowing hole and cover the fine soil until the seeds are submerged. Then appropriate watering can increase soil water content, promote seed water absorption and provide sufficient water for seed germination. But also to control the amount, not too much watering, resulting in stagnant water, soil consolidation, seed germination hindered. Finally, we should pay attention to do a good job of shading to prevent the temperature from being too high and affect the germination of seeds.

4. transplant at the right time

The seeds are transplanted about a year after sowing, usually after the plant buds are harvested. If it is ramet propagation, it is usually carried out in the full harvest of flower buds. Under normal management, seedlings can be formed in the winter of that year, new roots will appear and begin to grow. When transplanting, we should control the transplanting quantity according to the actual conditions such as soil fertility. After planting, pay attention to watering the roots, and then cover the base of the plant with a layer of plant ash. Then appropriate fertilization, mainly farm manure, but not too much, to prevent fertilizer damage and reduce the survival rate of planting.

The above is a brief introduction to the seedling technology of cauliflower. The seedling technology of cauliflower is closely related to its yield, so we must pay more attention to it. This is the end of today's introduction, this article is for reference only, I hope it can be helpful to everyone!
