Planting and propagation methods of blue flax

Soil requirements: the soil with loose and fertile, strong water retention and good permeability should be selected for blue flax cultivation. Sowing: soak seeds in warm water for about 6 hours before sowing, disinfect the soil with potassium permanganate, and cover the seeds with fine sand. Planting: half a month after sowing, choose the weather with a temperature of 10-20 ℃ for planting, pay attention to weeding and fertilization. Late management: watering should wait until dry and then watered thoroughly, and each fertilization should be cooperated with watering.

I. the planting method of blue flax

1. Soil

The main results are as follows: (1) the loose and fertile soil should be chosen as far as possible, and the soil with good water retention and permeability is suitable.

(2) choose the soil with high humus content, which can be matched with some pastoral soil, peat soil and so on.

(3) the soil needs to be raked and leveled before planting and watered thoroughly at the same time.

2. Sowing seeds

(1) before sowing, need to soak seeds, generally use warm water for about 6 hours, can achieve the role of sprouting.

The main results are as follows: (1) it is necessary to water thoroughly before sowing, and then disinfect the soil with 1500 times of potassium permanganate, and then sow the seeds evenly after the water permeates.

(2) after sowing, cover the seeds with fine sand with a thickness of about 2 cm.

(3) after sowing, we should pay attention to the change of temperature, heat preservation and moisture preservation, and the seedlings will emerge after about a week.

3. Colonization

The main results are as follows: (1) it can be planted about half a month after sowing, and the row spacing is about 25-30 cm when the temperature is between 10-20 ℃.

(2) because the flower and seedling is small, we should pay attention to weeding and applying a small amount of thin fertilizer after planting.

4. Management

(1) watering should follow the principle of getting wet every time it is dry, and then pour it thoroughly after being dry.

(2) when the flower seedlings are in the stage of bud development, fertilizer is especially needed, and more fertilizer is needed at this time.

(3) when fertilizing, we must follow the watering, while fertilizing while watering.

2. Propagation methods of blue flax.

1. Sowing and reproduction

The main results are as follows: (1) sowing and reproduction can be carried out both in spring and autumn.

(2) when sowing, try to choose the weather with the temperature between 15 and 20 ℃.

(3) it is necessary to soak the seed with warm water before sowing, so that it can accelerate germination and improve its germination rate.

(4) after sowing, it is necessary to water thoroughly and keep the soil moist at all times.

(5) after emergence, the seedlings should be properly carried out, good seedlings should be retained, diseased seedlings and weak seedlings should be removed, and the growth space between seedlings should be maintained.

(6) when it grows to about 8 cm, it needs to be treated with coring, and the interval between the first coring and the second time is about one month.

2. Cuttage propagation

The main results are as follows: (1) cutting propagation needs to be carried out before flowering.

(2) when cutting, do not choose too tender branches, too tender branches in the absorption of nutrition is not enough, can not guarantee the nutrition absorption in the later stage.

(3) the best cutting temperature is about 18 ℃, the wound is easy to be infected with bacteria if it is too high, and it is difficult to take root if it is too low.

(4) when cutting, disinfection should be done at the wound, and rooting agent should be applied.

(5) it needs to be watered in time after cutting to keep the soil moist.
