Zhuge Cai, alias: cauliflower, February orchid, purple gold grass, February blue;
Around February, blue and purple flowers began to bloom, with pink and white colors, also known as February orchid. It grows in plain, mountain, roadside and land edge. It has low requirements for soil light and other conditions, cold and drought resistance, and tenacious vitality (every kind of small plant is worthy of our attention, because they are all the favorite creatures of pot friends).
PS: it's said that Zhuge Liang used to pick tender shoots as vegetables when he led the army to go out to war, so it was called Zhuge CAI. Its flowering period is from early spring to June (very long). The pods are long and strip-shaped and mature in June. Seeds dark brown, ovate.
1、 Introduction to growth environment
Zhuge is mainly grown in northern China. It blooms purple flowers in spring in February of the lunar calendar. It is a kind of early flowering plant. The vitality of Zhuge is very strong, and it has strong adaptability to the environment in the north, especially in winter, it can endure the northern winter, and has a strong ability of cold resistance.
Zhuge vegetable especially likes dark and humid environment, and has no high requirements for water and light. It is suitable for growing in slightly alkaline soil in terms of soil. It is a perennial evergreen plant. It blooms first in early spring, which means to report the spring. It is a very simple and lovely plant.
2、 The advantages of Zhuge are as follows
1. Strong cold resistance, evergreen in winter
More shade resistant, as a ground cover, good coverage effect, green leaves, a piece of green, people like.
2. Strong adaptability
It can grow from Northeast China and North China to East China and central China. In case of heavy frost and snow in winter, although some leaves will also be frozen, new leaves can germinate, bloom and set seeds in early spring. The soil is not strict.
3. The flowers are blooming
Purple flowers, from bottom to top, bloom continuously from February to May and June, especially when planted in groups, like a blue and purple ocean. Such as planting on the river, seawall, green leaves, flower sea, sea water and blue sky interweave together, very spectacular.
3、 Natural habits
Zhuge is mainly grown in northern China. It blooms purple flowers in spring in February of the lunar calendar. It is a kind of early flowering plant.
The vitality of Zhuge is very strong, and it has strong adaptability to the environment in the north, especially in winter, it can endure the northern winter, and has a strong ability of cold resistance.

It is a perennial evergreen plant. It blooms first in early spring, which means to report the spring. It is a very simple and lovely plant.
4、 Breeding methods
1. Seed propagation
Sowing in autumn, winter to do a good job in keeping warm, Zhuge has a certain cold resistance, in the seedling period or pay attention to keep warm to ensure the survival of seedlings.
Before breeding, the soil should be renovated to ensure that the soil is loose and fertile, and water should be increased according to the growth of seedlings.
When the young buds grow into seedlings, we should increase the fertilizer to give them the nutrition needed for their growth, and correspondingly increase some light irradiation to increase photosynthesis and promote plant growth.
2 extensive maintenance
Zhuge Cai mainly propagates seeds and has strong regeneration ability. After the plant withers, new seeds will germinate and grow new seedlings. On the soil without tillage, seeds sown artificially can also grow seedlings, and have strong anti weed ability.
Some freshly harvested seeds have physiological phenomenon of late ripening, the germination rate of early sowing is low, and the shady hair lasts for 1-2 months or even longer.
3 sowing time
It can be used in summer and autumn, but August to September is the most suitable month. 300-400 seeds per gram, sowing rate 1 kg per mu (of course, it can also be potted for maintenance).
The basin soil is mixed with garden soil, perlite and plant ash, with a ratio of 6:2:1. Sufficient base fertilizer should be applied when the basin is put into the basin. After the seedlings are sprouted, the basin will be moved to a sunny place for routine fertilizer and water management.
4 environmental maintenance
Compared with other flowers, the cultivation and management is extensive and does not need more maintenance. It has strong cold resistance and shade tolerance. It can grow normally, blossom and bear fruit if it has some scattered light.
The best choice is loose and fertile sandy soil with good drainage. As long as timely watering, fertilization, a little management can be robust growth.
5 fertilization
Fertilize 4 times a year. Flower bud fertilizer in early spring, robust fertilizer after anthesis, strong fruit fertilizer after fruit setting, and strong seedling fertilizer before winter. If 0.2% potassium dihydrogen phosphate solution was sprayed on the leaves at the flower bud stage and young fruit stage, the flower color would be more gorgeous and the fruit would be fuller.
The leaves of Zhuge are green in winter and the flowers are blooming in early spring. In case of heavy frost in winter, it is necessary to strengthen frost prevention measures. If in order to eat, should often be ramets, in order to promote the germination of tender stems and leaves.
5、 Sowing maintenance
1. Water before sowing
It can promote the seed germination of weeds in the topsoil. The soil moisture is moderate and the seeds germinate within two weeks.
Weed can be eradicated by spraying herbicides. Attention should be paid to sowing after a period of rest after application of herbicides. Herbicides are harmful to any plant.
2. Pay attention to safety
Spraying should avoid chemical residues affecting the germination and growth of flower seeds. Before sowing seeds of wild flower combinations, a recovery period of 3-4 weeks should be reserved for the soil, and then wild flower combinations should be planted. Excessive use of herbicides may delay seed germination or weaken the growth potential of flower seedlings.
3. Management of germination period
Weeds should be removed immediately if they are found. The effective way is to use broad-spectrum herbicides or cut them by hand.
Ensure that weeds are removed before they fall. Annual or perennial weeds can be controlled with professional herbicides. These herbicides will not affect the growth and development of broad leaf plants, and can be used on wild flower combinations. Spraying them on newly grown seedlings will be very effective.
4. Pruning
If you want to make it look good, don't let it bear fruit. Cut it to 10 ~ 15 cm in height during the seed setting period. When preparing the land for autumn sowing, remove the ground debris that hinders the better contact between seeds and soil.
Although February orchid is a wild flower, it creates a natural and beautiful landscape effect that other flowers do not have. It is wildly cultivated, full of wild interest, and has a long viewing period. It is still very good!
6、 Pest protection
The main diseases and insect pests of Zhuge CAI are downy mildew. The leaves turn yellow green with polygonal spots and white downy mildew layer on the back, causing swelling, bending and green petals on the stems and flowers. Most of them occurred on the lower leaves of Zhuge.
The weather is cold and humid in April, and over planting will lead to the disease.
Treatment method:
Pay attention to ventilation and light transmission, do not plant too closely; you can also spray yimeijing.
Like to raise flowers, enjoy flowers, and communicate with basin friends! Can pay attention to public flowers and potted plants! huahuipz
