Planting methods and matters needing attention Water and Fertilizer Conservation of Zinghu Grass

There are all kinds of flowers and plants around us, which add a lot of color to our life. Zinnia is one of our more common flowers, because the ornamental value is so high that it is often seen in parks or communities. So do you know how to plant zinnia?

Planting method of zinnia

1. Water and fertilizer management

Watering: due to the high demand for light, the water is easy to evaporate, so it is necessary to maintain proper humidity and can be watered every day in summer.

Fertilization: 2-3 grams of compound fertilizer was applied to the bottom of the basin during planting, and 800 times solution was used to disinfect the roots after planting. The basin soil should be kept moist within one week of planting to promote the growth of the surface root system. When the root system grows to the bottom of the basin, topdressing can be started, fertilizing 2-3 times a week (applying water fertilizer in sunny days, the concentration of 200mg is controlled within 2-3 g / basin in rainy days), and calcium fertilizer can be added once.

2. Temperature and light

Temperature: hundred-day grass likes to warm to the sun, can not bear the heat, high temperature and cold, the suitable temperature for growth is 18-20 ℃ during the day and 15-16 ℃ at night. It grows especially fast in summer.

Lighting: can be directly used in full sunlight, direct sunlight. If there is not enough sunshine, the plant is easy to grow, the resistance is also weak, and flowering will also be affected.

Matters needing attention of hundred-day grass

1. Plant stereotyping

If the zinnia is not treated with coring, there are too few lateral branches and few flowers. Proper coring can promote the dwarfing of the plant and the increase of flowers. When the seedlings grow to 4 leaves, plant and pick the heart to promote the growth of lower branches to form a better plant shape.

After a week of planting, we began to pick the heart, leaving 4 pairs of true leaves, and depending on the growth and branching of the plant, we decided whether to pick the heart again or not. During flowering, phosphate and potassium fertilizers such as potassium dihydrogen phosphate continue to be added to promote the flower head to grow continuously. After the flowers withered, the withered flower heads should be cut off in time to reduce nutrient loss.

2. Pest control

Common diseases of zinnia: White spot, black spot, mosaic disease

The hundred-day grass still needs to be prevented from growing. The seedling growth period of zinnia is very easy to grow. Pay attention to lowering Wendy, picking the heart, and watering less.

Water and fertilizer conservation of zinnia

In addition to the seedling stage, it needs timely watering, in addition, it is generally not suitable for more watering. But the summer period needs to be watered frequently to keep the soil moist. Otherwise, it will cause small leaves and yellow flowers, poor color and luster, and the ornamental value will be greatly reduced. During the whole growth and development period, it is usually enough to chase three times of thin fertilizer. The mixed fertilizer of chlorine and potassium was mainly used in the seedling stage, the phosphorus fertilizer was the main fertilizer in the bud stage, and the compound fertilizer of chlorine, phosphorus and potassium was applied in the first ten days of September. If you fertilize too much, the plant is easy to overgrow and cause lodging.

When using zinnia as a cut flower, the tall type species should be selected, the heart should not be picked at the seedling stage, and the flowers at the top of the main stem should be used for the cut flowers. Because the tall planting plants are relatively tall and the stems and branches are easier to break in strong winds, it is necessary to set up pillars in time. In the high temperature season, the growth of zinnia becomes weaker, flowering is poor, and it does not bear seeds. At this time should be often watered, while the need for timely control of red spiders, autumn can continue to grow and blossom.

After each flower fade, the residual flowers need to be cut off in time to reduce the consumption of nutrients and facilitate flowering again. At the same time, fertilizers mainly based on phosphorus and potash should be applied for 1 or 2 times. Do not plant continuously in the same piece of land to reduce the occurrence of diseases.

The reason why a hundred days of grass grows.

1. Lack of light. Zinnia is a plant with high demand for light, and it can also change the florescence, advance or postpone it with the help of the adjustment of light. Seedling growth rate is very fast in the later stage, lack of light, and it is very easy to grow in vain.

2. Too much water. In places with strong light, water evaporates faster, but if the light is not enough, it will lead to slow evaporation of water in the basin soil, and if a large amount of water continues to be watered, it will affect the respiration of the roots. resulting in poor plant growth.

3. There is too much nitrogen fertilizer in sowing substrate. In the sowing medium of zinnia, a small amount of fertilizer can be applied, both phosphorus and potassium fertilizer and nitrogen fertilizer, but if the nitrogen fertilizer is excessive, it will cause the seedling to grow faster than the normal level in the later stage, thus growing in vain.

The above is the planting technology of zinnia summarized by the editor. I hope it can help you. I believe that many friends like hundred-day grass very much, in fact, you can plant a pot of hundred-day grass at home! When it blossoms, the dazzling flowers add a touch of color and vitality to your simple and warm room.
