rowing techniques of goldfish grass

A、Goldfish grass habit characteristics

Hardy, not heat tolerant. Prefer sunlight, also tolerate semi-shade. Goldfish grass growth temperature, September to March of the following year for 7-10 ℃, March-September for 13-16 ℃. Seedlings pass the vernalization stage at 5℃.

1、High temperature to goldfish grass

Growth and development of unfavorable, flowering temperature of 15-16 ℃, some species temperature exceeds 15 ℃. Does not appear branching, affect the plant state.

2、 Goldfish grass to moisture

More sensitive, potting soil must be kept moist, potted seedlings must fully watered. But the potting soil drainage should be good, can not water, otherwise the root rot, stems and leaves withered withering.


It should be fertile, loose and well-drained slightly acidic sandy loam soil. The soil should be fertile, loose and well-drained slightly acidic sandy loam.

4、Goldfish grass easy natural hybridization

In order to achieve the purity of the species, keep the seed mother plant Nga isolated seed harvesting. Of course many heavy petals and hybrid 1 generation goldfish grass will be difficult to receive seeds.

B、 Goldfish grass propagation cultivation

(1) Goldfish flower propagation

Mainly sowing reproduction, but also can cuttings. For some good varieties or heavy petal varieties that do not easily bear fruit. Commonly used cuttings propagation, cuttings are generally carried out in June-July.

(2) Goldfish grass seeds are tiny

Gray-black, about 8000 seeds per gram, germination rate of 60%. In 13-15 ℃ sowing, 1 week 2 weeks seedling, inserting seeds need to mix sand sowing.

(3) Usually

In order to bloom in early December, it is better to sow seeds in late July if 3-4 books (one book is a cut flower) are cultivated by removing the heart. If you do not remove the heart and cultivate a single book, it is better to sow the seeds in mid to late August.

(4) Cultivation

When the true leaves of the leaflets begin to grow, the first transplanting is done at a spacing of 3 cm x 3 cm. When the seedlings are 5-6 cm tall, transplant them for the second time at a spacing of 10 cm X IO cm.

(5) Goldfish planting period

The right time for planting is when the seedlings are 10-12 cm high, and if the seeds are sown in mid to late July, they will planted in mid-September.

(6) For those sown in mid-August

For mid-October planting, use a 1 m wide bed in the cultivation room. If you do not pick the heart to cultivate solitary plants, set them in 9 cm square.

(7) Cultivation of goldfish grass with heart picking

We plant 15-18 cm square and cultivate 4-5 copies. It is plucked 2 weeks after planting, leaving 4-5 sturdy lateral branches growing from the base. (8) Whether cultivating a single plant or multiple plants

When the plant is 25 cm tall, remove the lateral branches from the base as early as possible. Soon, when the seedlings grow to 25-30 cm high, you can open the net one or two layers.

C. The flowering period of goldfish grass

Greenhouse can used, plus different sowing period, cultivation method and different varieties to regulate.

1、Usually open field cultivation

Sowing in late August or September, flowering in April-May of the following year. Early spring cold bed seedling or spring and summer sowing, can be in June-July or September-October flowering. However, it does not grow as well as autumn sowing, and the flowering period is shorter.

2、Sowing in autumn

Then the following year flowering, short cut, can until late autumn flowering incessant.

3、Winter for cut flowers

Often sown in late summer, open field cultivation, cool autumn moved into the greenhouse. Keep 22℃ during the day and 10℃ during the night in autumn and winter, and the flowers will bloom in December.

4、Propagation method

It is mainly propagated by sowing seeds and group culture.

D、Sowing propagation

South of Yangtze River can be sown in autumn, September-October is good. The soil for sowing is a mixture of peat soil or decaying leaf soil, culture soil and fine sand, which is sterilized by high temperature and then loaded into the sowing tray. Goldfish grass 6300-7000 seeds per gram, after sowing without covering, the seeds will be lightly pressed that is.

1、 Goldfish grass germination temperature

is 21℃, cover with plastic film after watering. Put in semi-shade, about 7 days to germinate, do not sun exposure. After germination, the seedling growth temperature is 10 ℃, 6 weeks after the emergence of seedlings can be transplanted.

2、Sow seeds at the right time

Goldfish grass can propagated by sowing and cuttings, but mainly by sowing. Sowing is usually appropriate in mid-September.

3、Sowing substrate

Use sterilized humus soil or peat soil, generally use 30 cm caliber shallow pot.

4、Fill the pot with soil before sowing

Leave 1-2 cm on the rim of the pot. Then the potting soil will gently flattened and then you can sow the seeds. After sowing, cover with a layer of fine soil, and then gently compacted with a wooden board, so that the seeds are closely combined with the soil.

5、After sowing, place the pot in a water basin

Let the water penetrate upward from the bottom, until the entire soil surface is wet. Then cover the surface of the pot with glass to reduce water evaporation, and finally place the pot in the shade.

6、Post-sowing management of goldfish grass

The management after sowing is mainly water management. Watering should be even, not to make the pot surface too dry and wet. Lift the glass off at night to ventilate and breathe. Cover it again during the day to prevent water evaporation. The seeds can sprout out of the soil in 7 or 8 days after sowing. The seedlings can lifted off the glass after they emerge to receive light.

7、Goldfish grass transplanting

When the seedlings grow 4-5 true leaves, they can moved to a pot with a caliber of 8-12 cm. The potting soil should mixed with 7 parts of humus soil and 3 parts of garden soil. Seedlings should drenched with water from a spray bottle and sprayed thoroughly. As the seedlings grow up, change the box once again and plant in a 20-24 cm caliber pot.

8、 Goldfish grass is moisture tolerant and afraid of drought

Watering must master the “see dry see wet” principle, every 2 days or so spray 1 time water

E、Goldfish grass reasonable fertilization

To strengthen the fertilizer management, fertilization should pay attention to the nitrogen, phosphorus, potassium with. Goldfish grass has rhizobia, itself has nitrogen fixation, in general, without nitrogen fertilizer, moderate increase in phosphorus, potassium fertilizer can be. You can also use the more widely available nagric controlled release fertilizer.

1、 Goldfish grass in the growth period

Combined with watering once every half month to apply fermented oil residue water. When flower buds appear, spray with 0.1%-0.2% potassium dihydrogen phosphate solution is better, before each application of fertilizer should be loosened and weeded.

2、 Goldfish grass suitable for pruning

When the goldfish seedlings grow to about 1O cm, you can do heart removal treatment. To shorten the height of the plant, increase the number of side branches and increase the flowers. When pruning, cut off sick and weak branches, old and dead branches and overly dense branches. After each flowering, cut off the flowering branches to encourage them to sprout new branches to continue flowering.

F、 Goldfish flower open field cultivation should pay attention to

The goldfish plant is sunny and semi-shade tolerant, not high temperature and slightly cold hardy.

① Goldfish flower timely picking heart

In order to increase the branching, in cultivation need to pick the heart in time. This is especially important for medium and tall varieties. Generally in the seedling height of about 12 cm when the heart, the plant grows to 20 cm when the heart again. This will promote the growth of lateral branches and dwarf the plant.

②Goldfish grass used as cut flower varieties

It is not advisable to pick the heart, but to strip the lateral buds. The nutrients are concentrated on the main branches, but as the flowering branches grow, they should tied with thin bamboo in time to make them straight.

③Planting in the sun

As goldfish grass likes sunshine, it is advisable to choose a place with sufficient sunshine, loose, fertile and well-drained soil when planting. The soil is loose, fertile and well-drained. We need to pay attention to remove weeds, which is good for goldfish grass to grow and bloom.

④Reasonable fertilization and watering

Goldfish plant is a kind of flowering plant that likes fertilizer, and the seedlings grow slowly. Before planting, the land should tilled and fertilized with base fertilizer.

⑤After goldfish planting

It should watered once thoroughly and then depending on the weather conditions, to prevent the soil from being too dry and too wet.

⑥Fertilization of goldfish grass

In the growing period, apply 2 times of thin cake fertilizer or liquid fertilizer with nitrogen fertilizer to promote the growth of the aggressive leaves. But pay attention to not too much fertilizer, otherwise it will cause growth and affect flowering.

⑦Goldfish grass bud stage

1-2 times of phosphorus, potassium-based thin liquid fertilizer. It is good for bright flower color, pay attention to drainage after the rain. After flowering, you can cut off the above-ground part flushly and water once thoroughly. After that, you need to pay attention to fertilizer management, appropriate shade in summer to cool down, so that the autumn and can bloom.

⑧ Goldfish flower timely seed harvesting

Goldenseal can reproduce by self-seeding. When the fruit matures in June and July, it should be harvested in time. It can cut off together with the flower stalks and put on the bamboo weave to dry. Shake out the seeds and store them in a dry place, and sow them in September.

G. Potted goldfish grass

Commonly used 10cm pot, 6 weeks after germination of seedlings can be transplanted into pots. The growing period should kept at a temperature of 16℃, with moist potting soil and sufficient sunlight.

1、Some dwarf species

They can bloom 60-70 days after sowing.

2、Tall and medium varieties can plucked through the heart

To promote more branching and more flowering. So far, more growth regulating substances are used to dwarf the plant and regulate the flowering period. Spraying 0.05%-0.1% Bijou 10 days after heart removal has a significant dwarfing effect.

3. Seedling stage

Spraying 0.25%-0.4% Bijou can make the flowers bloom earlier and tighter. If spraying 0.4%-0.8% Bijou 2-4 times, it can delay the flowering.

4、Growing period

Fertilize once every half month, or use “Huiyou” 15-15-30 potted flowers special fertilizer. After flowering, timely topping, and additional fertilizer, temperature at 13-16 ℃, can continue to bloom constantly.


It is generally believed that the proper temperature for germination is 15-20℃, and the night is about 10℃. Therefore, the seeds are sown in late September and early October. Because the seeds are small, in order to avoid scattering thick, use sand or dry soil to mix after sowing or strip sowing.


During the growth of goldfish grass, it is usually fertilized once every 10 days or so.


Goldfish plant grows neatly under the condition of sufficient sunlight. The height is consistent, the flowering is neat and the flower color is bright.


Greenhouse cultivation temperature to maintain the night temperature of 15 ℃, daytime temperature of 22-28 ℃ or so. The temperature is too low, down to 2-3 ℃, although the plant will not suffer. However, the flowering period is delayed, the blind flower increases, and the quality of cut flowers decreases.
