Propagation method of tianrenju

There are generally three propagation methods of chrysanthemum, namely sowing and cutting. Sowing method is commonly used and most familiar. Let's study separately

Sowing and propagation

sowing and breeding are often carried out in summer. Seeds and substrates should be treated before sowing. The substrate should be disinfected to achieve the effect of killing pests and diseases. Seeds should be soaked in warm water for 3 ~ 10 hours, depending on the situation, as long as the seeds expand. When some seeds are small and difficult to sow by hand, they can be clamped on the surface of the substrate with tweezers. After all seeds are sown, a layer of substrate should be attached, about one centimeter thickAfter

sowing, you can choose to spray soak the substrate gently, so that the seeds can be washed out because of the excessive watering. Finally, cover the film. After sowing, the film shall be uncovered when the seedlings are unearthed, and the seedlings shall be exposed to light regularly. Pay attention to avoid strong light, for example, they can be exposed to light before 9 o'clock

Cutting propagation

Cutting propagation is also a relatively simple propagation method. The material to be selected for cutting is called cuttings. Cuttings usually choose the top tip with good growth and no diseases and pests. The temperature of cutting should be kept between 18 ℃ and 25 ℃. Cutting mouth should be disinfected. If the temperature is too high, it is easy to cause cutting mouth infection. At the same time, in case of low temperature climate, it can be covered with film to improve the ambient temperature. Shading is also necessary to cover more than half of the sun

Precautions for reproduction of Chrysanthemum

After sowing and propagation, it is necessary to remove the film and give appropriate light after the seedlings are unearthed. The light giving time should avoid the strong light period at noon. Generally, it should be placed in a cool place from before 9 a.m. to after 3 p.m. After the seedlings grow one after another, appropriate thinning should be done, that is, pull out the seedlings with poor growth, and leave growth space and sufficient water and nutrients for the well-growing seedlings

When cutting, the temperature should be controlled. Too low temperature is not conducive to the growth and survival of cuttings after cutting, and too high temperature will cause the cutting mouth of cuttings to be infected with bacteria. Appropriate shading should also be done after cutting. The shading effect should be more than half. When the temperature is high, the number of water spraying should be increased< span>
