Sowing and Propagation methods of Chrysanthemum morifolium Seeds

Chrysanthemum morifolium is an excellent flower and foliage plant with large color and dense branches and leaves, and can reproduce on its own. So, when will the chrysanthemum seeds be sown? The following editor will introduce to you the methods of sowing and propagation of Chrysanthemum morifolium seeds.

Chrysanthemum morifolium is mainly used for seed sowing and propagation from March to April every year. When sowing in the indoor pot in early spring, a sowing basin or wooden box with a diameter of 30cm and a depth of 5cm is usually selected, and the drainage hole is covered with broken tiles, and then coarse gravel, coarse gravel, coarse culture soil and sowing soil are added successively. Then, the soil surface is compacted and flattened with wooden strips, and the soil is separated from the basin along the 1cm. After soaking the basin soil with the "basin immersion method", the basin is put forward and sowed after all the moisture is infiltrated.

When sowing, open the seed bag and spread the seeds evenly into the basin, or mix the seeds into the fine sand and sprinkle them evenly into the basin. After sowing, cover a thin layer of fine soil, then cover the disk with glass, and then cover the glass with newspaper to reduce the evaporation of water. Before the seeds sprout, keep the soil moist, do not make the seedling bed dry and wet, or too dry and wet. In the morning and evening, the glass should be opened for a few minutes, ventilated and covered during the day. After the seed is germinated and unearthed, the mulch should be removed in time, see the light step by step, and transplant when 2 true leaves are grown.

The management of golden rooster chrysanthemum is relatively simple. When the seedlings grow true leaves, apply nitrogen fertilizer once; when the seedlings grow to 2 or 3 true leaves, they can be transplanted. After one transplant, it can be planted in the flower bed. After planting, water should be watered in time so that the root system is closely connected with the soil. During the growing period, liquid fertilizer was applied for 2 to 3 times, and phosphorus and potash fertilizer were used together with nitrogen fertilizer.

Usually the soil is dry and wet, and there can be no waterlogging. Drainage and waterlogging prevention should be carried out in time after rain. High temperature, high humidity, poor ventilation, aphids and other diseases and insect pests should be sprayed in time. If you want to make the golden rooster chrysanthemum blossom more, you can pick the residual flowers after the flower, and chase the fertilizer once from July to August, so that the National Day can bloom luxuriantly.

[seed harvesting] the harvest site is the head of Chrysanthemum morifolium. Usually between August and October of each year, most mature heads of achenes are cut, dried and placed in a dry, cool place to concentrate on impurity removal and clear seeds.

[grading] the seeds collected should be graded on the premise of ensuring the cleanliness of the species, normal water content and no foreign body pollution; the germination rate of primary seeds is ≥ 98%; the germination rate of secondary seeds is ≥ 95%; and the germination rate of tertiary seeds is ≥ 92%. When seeds at all levels are in use, the germination rate is allowed to be lower than 5% of the corresponding standard; with the extension of storage time, the germination rate standard should be lowered accordingly.
