Propagation and Seedling technique of Peacock Grass

In previous articles we talked about peacock grass suitable for growing on the edge of flower beds or in gardens, but also can be made into potted and cut flowers material. Peacock grass was also called "sunflower" in the past, and later this title was taken away from Xiang Ri. Peacock grass is a sun-loving plant, but even if there is no light, it can still bloom. As long as there is a suitable temperature, humidity conditions, can grow freely, is a very strong ability to implement the flower plant. Today we will introduce you to the seeding and seedling technology of peacock grass.

Due to its strong ability to adapt to the environment, peacock grass can be sown all year round in the south, while in the north due to the cold weather, it is recommended to sow in spring. If mass sowing, can adopt the way of tray seedling propagation. To complete the seeding work, this process needs to go through four stages:

1. The embryo will be white 2-5 days after sowing. The seed germination of peacock grass does not need to meet the light conditions. After sowing, it is covered with a thin layer of straw, which can not only shade the seed, but also moisturize the seed. As long as the culture soil is slightly moist, it is necessary to avoid the soil being too moist, and it can germinate normally at a normal temperature of more than 20 degrees.

2. After one week, the seeds can be completely unfolded from white to leaves. When the radicle appears, we must pay attention to taking cooling measures. At the same time, we must water the soil after it is slightly dry. We should increase the light appropriately and apply a small amount of fertilizer, which is more conducive to plant rooting and sprouting.

3, in the rapid growth period of planting seedlings to avoid excessive humidity, but also to ensure that seedlings water supply, so watering must grasp this degree. Do not inhibit seedling growth due to too dry culture soil, or even lead to seedling wilt, can be cooled. In addition, alternate topdressing every other week, but ammonium nitrogen should not be used when the temperature is below 18 degrees Celsius. With these measures, the root system of the plant will grow to 3-5 cm, the height of the seedling will reach 3-4 cm and 2-3 pairs of true leaves will appear.

4, the fourth stage belongs to the seedling stage, at this time the root system of the plant has basically grown, there will be at least 3 pairs of true leaves, then you can continue to reduce its temperature to 15 degrees Celsius, but also can not use ammonium nitrogen. As in the second stage, allow the soil to dry out during the second watering and increase ventilation to prevent excessive growth.

But through practice found that some pot friends will appear seedling failure phenomenon, then we need to find out the reasons for failure. If there is seedling failure or other problems, we mainly investigate from the following aspects:

1. PH value of soil

If the pH value of the soil is too low, it will lead to necrotic spots on the old leaves, burnt edges, and necrosis of growing points; if the pH value is lower than 6, it may also cause excessive trace elements. The treatment measure is to adjust the pH value to between 6 and 6.7, which can be adjusted by adding lime water.

2. Improper seedling temperature

In order to prevent disease infestation, it is necessary to raise the temperature and control the humidity properly in early spring. However, if the temperature is too high, it will also cause damage, and it will also cause disease until the plant is dead and lodging.

3. Insufficient nutrient supply at seedling stage

The plant should pay attention to nutrient supply during seedling stage. If water and fertilizer are insufficient during seedling stage, the plant will grow slowly and become thin, and eventually become a small old seedling.

By analyzing the phenomenon, we can not only find the cause of the problem, but also prevent similar incidents in future work. The above is a small series for everyone to introduce the knowledge about peacock grass seeding seedlings, I hope to help you.
