Flower name: sunflower
Seeding time: spring, summer, autumn
Form characteristics:
It's a year of raw meat herbs. Ten to 15 cm tall. The petals are colorful, white, dark yellow, red, purple, etc. There are many types of horticulture, with single, semi-heavy and heavy petals。
Growth:
The warm, sunlight-rich and dry environment is extremely infertile, generally adapted to the soil and self-sowning. The sun blooms in the morning, in the evening and in the dark, so there are sunflowers and midday flowers. - june to july。
Cultivation:
Sunflower seeds are very small. The seedlings are used to sow small amounts of fine pebbles, or to sow only slightly to ensure sufficient humidity. The sprout temperature is 21-24°c, which is about 7-10 days old, and the seedlings are extremely thin, so that if the temperature is high and the seedlings grow quickly, they can form a thicker, fleshier branch. At that point, the seedlings can go directly to the basin, using a basin of about 10 centimetres in diameter, with two to five plants per basin, with high rates of survival and rapid growth。
Approach
To level the container and to level the ground, the cut branch of the sun will be inserted into a hole made of bamboo chopsticks, with a maximum of 2 centimetres in depth. In order to make the pelvis as fast as possible and to be full, one can see the size of the bouquet, provided that it is two centimetres away and multiples can be inserted (which can be spread over other basins when the bouquet becomes congested). Then you can water it. New seedlings can either hide it or stay clean。
Normal maintenance
Sunflowers have few pests. A regular humidity of 1 in 1,000 potassium phosphate is applied once a month to achieve a colorful and flowering purpose. If there are multiple varieties in one basin, each flower will open and its value will be higher。
We'll grow them in winter
Every year after the frosting (shanghai region), heavy petal sunflowers are moved indoors to sunlight. Put it inside the glass window after winter, so that the pelvis can dry up a little bit, and you can get over the winter safely. When the following year is clear, the flower basin can be placed out of the window and, in the event of a cold flow, in the window for maintenance。
Solar flower cultivation has to go through a series of processes, such as preparation of the soil, seeding, seedlings, seedlings, seedlings, head-picking, irrigation and seed harvesting。
Prepare the soil
Although “infertile” is one of the characteristics of solar flowers, which grow without concern for the good or the bad of the soil, they are always expected, as flower breeders, to grow strong, leafy and flowery, and therefore prepare, as far as possible, a loose, ventilated and productive soil。
During this period, oily household foods, such as sesame powder, low-foot soybean slag (for fermentation), or fish intestines (for early fermentation) may be collected as base fertilizer。
Seeding
At the end of april and the beginning of may, the climatic conditions around gangnam were the most suitable for planting. Last year, on april 28, i had seeded, three or four days later, to break the buds, and june 14, to bloom, to last a month and a half, 10 days ahead of the previous 55 days, but at a very fast pace, the magic of which is at this stage of planting。
In order for the seeds to be in close contact with the soil, solar seedlings can simply spread the seeds evenly on the surface of the fine particles of the soil, and then recaptulate a layer of the fine layer。
Feeding
It was important to ensure that young children survived the extraordinary period. Be patient enough to take care of them, as if they were babies in the middle, and if they were not heeded, they would die and the rate would be significantly reduced。
Slender and slender
The seedlings are also called seedlings, which allow them to keep a certain distance from them. The shizumi tool chooses a sarcasm. When the seedlings grow a few millimeters high, they can start. By batching and time-drive, the relatively thin ones are always drawn, leaving strong ones until there is a gap of three or four centimetres between seedlings and seedlings。
Take your head off
When the sapling grew to three or four centimetres high, it grew branches from the roots. At this point, the head of the main branch is removed, and a sprouting of the branch will soon emerge at the end of the mouth. When the branch of the root is long enough and the branch is cut off, the sunflower is shrunk and the strain looks good。
Water
At the nursery stage, the weather is not very hot, the water evaporates slowly and should not be overfilled. When the flowering period is in the middle of the sky, it needs to be filled with water。
Seeds
The ripe sunflower seed is silver gray, but it is difficult to harvest it at the right time. The seed trap is either a crack or the seed is gone. So it's best to touch those yellow seed shells with your hands on a regular basis; it doesn't fall off, but it's yellow, it's white, it's taken off, and it's black with two fingers, because it's still a little high, and later the black seed becomes silver ash。
Sunflowers are small and large, small and large. And the sunflower does not require your careful care that it grow in abundance, provided that there is plenty of sunlight。
