The breeding method of Qianrihong

Thousand-day red is a very common flower plant in China, with long flowering period and beautiful flowers, so it has high ornamental value. Therefore, it is very popular in our country. Now the area of planting thousand-day red in our country is also relatively large, and when planting thousand-day red, the breeding work is very important. So how to breed thousand-day red? Today, the editor has brought you the breeding method of thousand-day red, let's take a look at it!

First, sowing and reproduction

1. Seed collection and soaking

When Qianrihong is sowing and propagating, we must first do a good job of seed collection. Seed collection should be started in September every year. After seed collection, the seeds should be sowed around Ching Ming Festival in the following year, and they can be planted in June. However, because the seeds of thousand-day red have a lot of hairy hair, so the emergence speed is relatively slow. Therefore, in order to improve the emergence speed of seeds, we also need to do a good job of seed soaking and germination before sowing. Before sowing, soak the seeds in warm water for about 1-2 days. Then remove the seeds and air-dry, wrap them in a wet cloth and put them in a warm place to sprout.

2. Sowing seeds at the right time

When most of the seeds are white, they can be sown. Because the seed of thousand-day red is relatively large, so we can sow the seed directly in the ordinary sowing ground. However, the sowing land should be sunny, good drainage and irrigation, soft and so on, and the soil should be properly covered after sowing to control the temperature. When all the seedlings are unearthed, it is necessary to do a good job of interplanting. During the growth of seedlings, it is necessary to control the amount of water and fertilizer, not too much, to prevent excessive growth of seedlings. And in the seedling stage, to pick a heart for dwarfing planting.

2. Cutting propagation

1. Cutting method

The time of cutting propagation is usually in July. First of all, we have to choose cuttings with a length of about 5 cm and about 4 nodes. Then the leaves that need to be inserted into the soil nodes are cut off to avoid excessive evaporation of water. After cutting, the temperature should be controlled at about 25 degrees, and it can take root and transplant in about 20 days. If the temperature is below 20 degrees, the rooting days of cuttings will need to be delayed by about a week. However, if you want to take root earlier, then we can apply an appropriate amount of rooting agent at the base of the cuttings. The effect of rooting agent is obvious, and it can be transplanted about a week after cutting.

2. Post-cutting management

Before cutting, we should pay attention to wetting the soil to avoid cutting injury and improve the survival rate of cuttings. Then we should pay attention to the cutting depth and insert a node or so into the cuttings. It is necessary to water the cuttings in time after cutting to improve the contact area between cuttings and soil. Then keep the soil moist every day and do a good job of shading and shading. Especially in summer, the shading rate of the seedling bed should be kept at about 85%, and can be appropriately reduced in spring and autumn when the light is not strong.

The above is a brief introduction to the breeding method of thousand-day red. That's all for today's introduction. This article is for reference only. I hope it can help you all.
