Introduction to cultivation techniques and breeding methods of green flowers and mosquito repellent grass

Mosquito repellent mainly refers to transgenic geranium, which uses transgenic technology to embed "vanilla" with the structure of mosquito repellent gene-citronellal gene. Mosquitoes and vanilla are a good combination of nature and modern high-tech bioengineering. Mosquito repellent products. Do you know how to grow mosquito repellent? This is an editor who introduces the cultivation techniques and breeding methods of insect repellent.

Cultivation techniques of mosquito repellent

Change the basin and soil

Mosquito repellent grows rapidly. It needs to be replaced every year to increase soil and fertilizer. It is usually in the early spring from February to early March. First prune it, leaving only 3 lateral buds on each base, then remove the basin, and the surrounding roots must be removed. Replace fertilizer with new soil and apply base fertilizer. After the release of the new branch in early April, thin organic liquid fertilizer was applied once a week and gradually removed from the outside in the second half of the year. Light scattered by moving to the balcony in early June.

The maintenance of the garden is moved to the shade of the trees, the east or shade of the house. Pay attention to the whitening of the surface of the small potted soil, and pour water when the surface of the large potted soil is 1 cm. From July to August, the high temperature should be cooled by spraying water to keep the surrounding environment moist and there is no water in the basin. In mid-October, before the frost comes, the winter room temperature is no less than 12 °C, the light is abundant, the air is fresh, and the flowers are blooming.

Professional cultivation costs a lot of flowers for the May Day festival, which can be pruned at the end of autumn, enter a low greenhouse (below 10 °C), maintain adequate light, control water and moisturize, and properly ventilate and maintain.

Biological characteristics and cultivation techniques of mosquito repellent: Xiguang should have a slight shadow except summer, and direct sunlight should be in autumn, winter and spring. For warm water, 10-25 °C is the suitable growth temperature, lower than 7 °C, higher than 32 °C is disadvantageous to growth, pour water once every 3-6 days, but can not accumulate water.

1. Preparation of nutrient soil

Mosquito-repellent vanilla (mosquito repellent) prefers neutral and acidic soils and is usually fertilized every 15-20 days. When the plant height is 30 cm, 40 mosquito leaves have a better mosquito repellent effect, and the yellow leaves should be removed at any time. The basin grows very fast at the seedling stage, so the basin is more diligent at the seedling stage. 6 parts of peat, 1.5 parts of vermiculite, 1 part of perlite, 1 part of coal ash and slightly acid neutral, you can also buy good products from the flower market (pH 5.5-7). After six months, these plants are highly adaptable and can be used freely. Biennial plants are wrapped in wood and can be trimmed and shaped freely according to personal preference.

two。 Temperature control

Mosquito-repellent vanilla (mosquito repellent) is most suitable for temperature growth at 10-25 °C, safely above 0 °C in winter and 15 °C higher than normal lemon flavor. The higher the temperature, the stronger the fragrance. Spraying the right amount of water on the leaves of plants can continuously release the source of citronellal, which makes mosquito repellent better.

3, light adjustment

Mosquito-repellent vanilla (mosquito repellent) is shady, which is not resistant to strong light when growing, especially in summer, and can be planted under trees or under shade. Family potted plants are usually raised indoors.

4. Water and fertilizer management

After each change of basin, water should be watered once, and the seedlings should be fertilized 10 days later. Spring and autumn are the exuberant growing periods of plants. 20-10-20 and 14-0-14 water soluble compound fertilizer 200ppm liquid was applied every 15 days. Watering should talk about the principle of drying between studies. In summer, high temperature should be watered less and not fertilized, which is beneficial to root development and improve disease resistance. In family planting, you can also use a small amount of cake fertilizer, rice water and so on.

Breeding methods of mosquito repellent

Seedling reproduction, mainly using adult plants to trim cuttings, cut the side branches of mosquito net vanilla around October every year, cut into 5 cm slices, soak 10 mg / L acetic acid for 15 minutes, and then insert it into rocks or rivers. The sand seedbed is covered with film and sunshade nets.

Sprinkle water 3 to 5 times a day, usually take root in about 10 days, 20 days when the new buds grow to about 5 cm, can be transplanted to the pot. Tissue culture technology is mainly used in large-scale seedlings.

Usually sowing, cutting and breeding, cutting in spring and autumn are easy to survive. In the first 10 days of March, plant the seeds in clean sand 3 centimeters deep. After 4 hours of pouring, pour water again, and then keep the soil moist, not too dry or too wet. In early spring, the room is warm and bright. It can germinate and take root for about one month at room temperature of about 20 ℃. The plants are then planted and the seedlings are cultured in small pots on the common culture soil. When the seedlings grow vigorously, white roots appear from the bottom of the basin, and some fragments of the soil are filled with fertilizer to make base fertilizer, and then planted in chrysanthemum buckets.
