Who can talk about the planting technology of snow chrysanthemum in Tianshan Mountain?

Saussurea kunlunensis is a seed for propagation. The optimum germination temperature of Saussurea kunlun seeds is 15 ~ 25℃. The optimum relative humidity for germination is 65% ~ 75%; Proper hormone treatment can improve the germination potential of Saussurea Kunlun seeds, and there is no significant difference in the effect of light on the germination rate of seeds. Spring sowing in Xinjiang Plateau. Sowing in May and flowering in August. Keep the spacing of 40cm when planting, so as to pick it in the future.

Sowing of Saussurea Kunlun

Time: Sowing often takes place in spring.

Sowing: Draw parallel lines at intervals of 40 cm in the ground, and the depth of each line is about 2-3 cm. Mix the seeds of Kunlun Snow Chrysanthemum with sand at the ratio of 1:5, and evenly spread the soil mixed with seeds into parallel lines. Do not cover the parallel lines with soil. 500 grams of seeds per mu is enough.

Water the seeds within two days after sowing. The water should be small for the first time. Don't rush the seeds out of the parallel lines.

You can see the seedlings in about 15 days.

Most seedlings can be transplanted when they have three or more leaves.

Transplantation of Saussurea Kunlun

When transplanting seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the planting hole as the base fertilizer (base fertilizer) with a thickness of about 3 cm ~ 5 cm, then cover it with a layer of soil, and release the seedlings, so as to separate the fertilizer from the roots and avoid burning the roots. After seeding, backfill the soil, cover the root system, compact the soil and water it once.

Picking the heart of Kunlun Snow Chrysanthemum

Generally, the core is removed twice before flowering to promote the germination of more flowering branches. One to two weeks after transplanting, or when the seedling height is 6 ~ 10 cm and there are more than 6 leaves, remove the top and keep the lower 3 ~ 4 leaves to promote branching. 3 ~ 5 weeks after the first coring, or when the side branch grows to 6 ~ 8 cm, the second coring is carried out, that is, the top of the side branch is removed and the four leaves below the side branch are retained. After coring twice, the plant type will be more ideal and the number of flowers will be more.

Fertilizer and water management of Saussurea Kunlun

Like other grass flowers, Kunlun Snow Chrysanthemum needs more fertilizer and water, but it is required to follow the principle of "light fertilizer, diligent application, small amount and more nutrition" and keep the leaves and flowers dry at night after fertilization.
