Matters needing attention in the planting of Corolla

First of all, we must pay attention to promoting seedlings when planting crown flowers. The germination rate of crown flowers is about 40% to 90%, and the uncertainty is very great, so we should take certain artificial measures to help it germinate before sowing. A small number of seeds can be soaked in 15% sulfuric acid for half an hour, while a large number of seeds generally choose to use a rice mill to break the seed skin and sow seeds.

Matters needing attention in sowing and Propagation of Corolla

The flowers and colors of Corolla are bright, and they have been cultivated for more than ten years in China. They are widely used as ornamental flowers. Corolla has strong growth and strong adaptability, so it is loved by many flower friends. Artificial propagation of Corolla can use the method of sowing, the editor will introduce to you the matters needing attention in sowing and breeding.

Small crown flower

The amount of seed used per mu 0.5-1KG can be sown in spring, summer and autumn. Corolla has small seeds and shallow sowing, so the soil should be carefully prepared before sowing. The hard seed rate of the seeds is as high as 70 ℃, and the seeds must be treated before sowing. A small number of seeds can be soaked in 15% sulfuric acid for 20 minutes, or soaked in warm water of 70 mi 80 min, naturally cooled, soaked for about 12 mi for 15 hours. A large number of seeds are generally crushed by a rice grinder before sowing. The germination rate is generally 40%, 90%, and some hard grains can not sprout until the second year. The growth of weeds is slow at seedling stage, so weeds should be weeded in time. Once established successfully, weeds can be restrained.
