Parse the growth of dwarf sunflowers

The sunflower growth cycle is short, bright and strong, very resistant to drought. No need for meticulous care in the growth process, which is a great choice for a flower lover.

The sunflowers are short and unafraid of heat. In addition to the winter season, the temperature of the plant is more than 15 degrees in the night and above 20 degrees in the daytime. So the area of the Yangtze river delta can be seeded from April to September. (the sowing of visible flowers in September may have some effect on the development of the seed after the flowers, but no problem is not considered.)

Sunflower seeds are the common sunflower seeds and sunflower seeds, which are in line with the stir-fry seeds. But horticultural varieties of dwarf sunflower seeds are smaller. Common varieties are: smile (laughter), folk song, (toy) bear, miss sunshine, etc., the plant type height is between 15CM and 30CM, suitable for potted plants.

Sunflower seeds are large, thin, and full of particles. The seeds are strong, resistant to resistance, seeded with seedlings, common peat, and even common garden soil, without special seedling treatment. When seeding, place the top of the sunflower seeds vertically into the sowing medium and cover the soil about 1-2cm. Keep the medium moist before the seedling. Usually three to seven days. The seeds germination and the appropriate covering will help to remove the cap when it sprouts.

After the seed germination, keep the medium moist, and put it in the bright spot of sunshine management. Keep the environment and the medium moist, can accept stronger sunlight, the light deficiency will be long. (the third to fifth day) after the budding opposite leaf to appear, such as planting seedlings too close to thinning out at this time (were worried that germination rate, seedling individual pieces into 2 seed). Use a toothpick, tweezers, etc. To carefully remove the medium and remove the seedlings from the small pot. During this period, the root system does not affect the growth of the plant. When I was moving, one of the roots broke completely and buried it in a small pot. It turns out that there was no effect at all in later growth, and the root system was very healthy.

The seedlings grew from 4 to 6 real leaves, and the basin was made of 14CM diameter (the basin in the 5th), and the implant was 70% nutritive soil + 30% vermiculite, and 30 grams of decayed chicken manure as the base fertilizer. The seeds can be buried directly in the basin. The small pot is planted carefully to take the soil to remove the seedling, bring the soil into the new basin. Pouring water.

The shade ventilation should be fixed for a day, and it will be managed by daylight. Every morning water floods, sunflowers grow fast, water needs big. The more the leaves, the faster the water consumption.

The seedling period is once a weekly NPK composite equilibrium water soluble fertilizer, 1000 times irrigation.

About 25 days after the shoot, the top of the plant begins to appear, which is the most vigorous period of the sunflowers. On a sunny day and morning, two times a day, a rainy day in the morning. 5-7 days a time of phosphate fertilizer, water soluble 1000 times root. Avoid water from the top when watering or raining.

A month after the budding flower buds swell gradually Sunflower is the top priority of plants, most complete varieties can only at the top of the inflorescence development, and each axillary branches and small bud sprouting could, these are usually done will not have the opportunity to develop, but will share nutrients, so we want to give him gather the lateral bud, look at each petiole, this branch is the flower bud, aborted. The flower bud that has fallen, throw into the corner of the flowerpot, come to the soil in the soil, make fertilizer.

Sowing for 41 days, the plant is about 20CM - 25CM, and from now on it will not be anywhere from a third to a half.

Sows for 47 days and begins to see yellow petals in the bud.

For 50 days, the sunflowers are opening up.
