1. Brief introduction of goldfish grass

Goldfish grass likes sunshine and can withstand semi-overcast. Sex is more cold-resistant, not resistant to heat. It is suitable for loose, fertile and well-drained soil, and can grow normally in calcareous soil. The plant height is 20ml / m, and the leaf blade is oblong-lanceolate. Raceme, Corolla cylindric lip-shaped, base dilated into a saccate, upper lip erect, 2-lobed, lower lip 3-lobed, spreading external curvature. There are white, light red, deep red, flesh color, dark yellow, light yellow, yellow orange and other colors.

Goldfish grass can be potted, because of its colorful, very suitable for viewing. Native to the Mediterranean region and distributed as far as Morocco and Portugal in the north, France in the south and Turkey and Syria in the east. Goldfish grass gets its name because it looks like a goldfish. Goldfish grass gets its name because it looks like a goldfish. At the same time, it is also a traditional Chinese medicine, which has the effect of clearing heat and detoxification, cooling blood and reducing swelling. Can also extract oil for consumption, nutritious and healthy.

Second, how to raise goldfish grass

1. Sowing seeds at the right time

Goldfish grass can be propagated by sowing and sowing, but mainly by sowing. Sowing is usually in the middle of September. The sowing medium uses sterilized humus soil or peat soil, generally using a shallow basin of 30cm caliber, sowing full of basin soil, leaving 1--2cm along the edge of the basin and then gently flattening the basin soil. After sowing, cover with a thin layer of fine soil, and then gently compaction with wood to make the seeds closely combine with the soil. After sowing, put the basin in a water basin, let the water permeate upward from the lower part, soak until the whole soil surface is wet, then cover the basin with glass to reduce water evaporation, and finally put the basin in a cool place.

2. Post-broadcast management

After sowing, it is mainly water management, watering should be uniform, do not make the basin too dry and wet, lift the glass at night, make it ventilated, cover it during the day to prevent water evaporation. The seeds can sprout and unearthed 8 days after sowing, and the seedlings can lift the glass and receive light after they are unearthed.

3. Transplant

When the seedlings grow 5 branches and leaves, they can be moved to a flowerpot with a caliber of 8--12cm. The pot soil should be mixed with 7% humus soil and 3 portions of garden soil; the seedlings should be watered with a spray pot and sprayed through; with the gradual growth of the seedlings, change the pot again and plant it in the pot of 20--24cm caliber.

4. Temperature and humidity

Goldfish grass is more resistant to cold and semi-shade, and can resist the low temperature above-5 ℃, and it is easy to freeze to death under-5 ℃. Goldfish grass is resistant to moisture and is afraid of drought. In the process of maintenance and management, watering must grasp the principle of "dry and wet" and spray water every 2 days or so.

5. Rational fertilization

Fertilization should pay attention to the cooperation of nitrogen, phosphorus and potassium, goldfish grass has rhizobium, itself has the role of nitrogen fixation, in general, there is no need to apply nitrogen fertilizer, appropriate increase of phosphorus and potassium fertilizer. During the growing period, the fermented oil residue water was applied every half a month with combined watering. When the flower buds appeared, it was better to spray with 12% potassium dihydrogen phosphate solution, and the soil should be loosened and weeded before each fertilization.

6. Suitable for pruning

When the seedlings of goldfish grass reach about 10cm, coring treatment can be done to shorten plant height, increase the number of lateral branches, increase flowers, cut off diseased and weak branches, withered old branches and overdense branches during pruning, and cut off flowering branches every time after flowering, so as to promote new branches to sprout and continue to bloom.
