The latest mosquito repellent cultivation methods and precautions

Now it has entered summer, and mosquitoes come out whenever summer comes. Mosquito control is one of the important events in summer. Many people will choose to decorate plants with mosquito repellent effect at home. Mosquito repellent is one of the common varieties. Mosquito repellent is currently sold in the market, but how to raise mosquito repellent? This is a problem. The editor has sorted out some information about mosquito repellent aquaculture. Let's learn about it.

Introduction of basic information of mosquito repellent grass

Mosquito repellent grass, also known as mosquito repellent vanilla, transgenic geranium, mainly refers to transgenic geranium, using transgenic technology. The mosquito repellent gene-citronellal gene structure was implanted into "vanilla". Using its own unique release system as a carrier, citronellal substance was released into the air and implanted into the DNA gene structure with fresh odor and air purification to form a "natural evaporator" and the aroma overflow achieved mosquito repellent effect.

Pelargonium is a perennial herb or shrub, up to 1 meter high. The stem is erect, 80ml 90cm high, grayish green, the base is woody, the upper part is fleshy, densely glossy pilose, fragrant, with strong vitality. Leaves with long stalks, broadly cordate-ovoid, 5-7 palmlobes, lobes redivided, lobes serrated at edges; flowers small, densely umbellules opposite leaves, whole plant steamed aromatic oil, often cultivated as aromatic plants. Because of its fragrance, it is often watched in pots. Originally from South Africa.

In fact, there is no mosquito repellent plant, it is only a commercial name, the reason why it is called "mosquito repellent" is for the sake of merchants to sell.

All varieties of geraniums have no mosquito repellent effect, but only artificial transgenic geraniums have this effect.

Breeding methods of mosquito repellent grass

Mosquito repellent grass is usually sown and propagated by cuttings, and cuttings are easy to survive in spring and autumn. In early March, the seeds were sown into clean fine sand, 3 cm deep. Water thoroughly 4 hours after insertion, and keep the basin soil moist after that, not too dry or too wet. Put it in a warm and bright place in the room in early spring. It can sprout and root in about 1 month at room temperature of about 20 ℃. Then, the seedlings were raised with Xiaopeng on the ordinary culture soil, and white roots emerged from the pots when the seedlings grew strong. Some broken hooves were padded under the fertilized culture soil as base fertilizer, and then planted in chrysanthemum bucket pots.

Culture methods of mosquito repellent grass

1. Soil: mosquito repellent grass prefers neutral and acidic soil, usually fertilizing once every 15-20 days. The mosquito repellent effect is best when the plant height is 30 cm and 40 leaves, and the yellow leaves should be removed at any time. It grows very fast in the seedling stage, so the basin is changed more frequently in the seedling stage. 6 parts of peat soil, 1.5 parts of vermiculite, 1.5 parts of perlite and 1 part of coal ash are used in 6 months. The PH value is slightly acidic and neutral, and the prepared commodity (PH value 5.5-7) can also be purchased from the flower market. After six months, the plant has strong adaptability and can use soil at will. The main stem of the biennial plant is Lignified, which can be trimmed and modeled freely according to personal preferences.

2. Temperature: the most suitable growth temperature of mosquito repellent grass is 10-25 ℃, it can survive the winter safely above 0 ℃, and lemon fragrance can be distributed normally when it is above 15 ℃. The higher the temperature, the stronger the fragrance. Spraying an appropriate amount of water spray to the plant leaves can make citronella aldehyde release continuously, thus making the mosquito repellent effect better.

3. Lighting: mosquito repellent grass likes shade and is not resistant to strong light when growing, especially in summer. It can be planted under trees or shaded places. Family potted plants are usually sprouted indoors.

4. Water and fertilizer: water should be watered once after changing pots, and fertilization should be started after 10 days of slow seedling. Spring and Autumn is the peak period of plant growth. 20-10-20 and 14-0-14 water-soluble compound fertilizer 200ppm solution was applied every 15 days. Watering should be based on the principle of humidity between dryness and dryness between studies. High temperature in summer should be less watering and no fertilization, which is beneficial to the development of root system and improve disease resistance. Family cultivation can also apply a small amount of cake fertilizer and rice water and so on.

5. Insect disease: root rot or stem and leaf rot caused by improper management, followed by leaf shrinkage, black spots, and then the whole plant shrinks. This is caused by too much humidity, too high temperature, poor ventilation or excessive seedling density. Can be sprayed with fungicides such as carbendazim or carbendazim (800 to 1000 times liquid). But do not spray frequently.

Matters needing attention in the culture of mosquito repellent

The sudden loss of leaves in a short period of time is often due to excessive temperature changes or lack of light. The leaves turn yellow and soon fall off, mostly due to insufficient light and too much watering. This phenomenon can also occur when the temperature is too low in winter. The dry tip or the edge of the leaf is scorched, sometimes due to excessive light or dry air, and sometimes due to excessive fertilization or dry basin soil. Branches and leaves grow, mainly because there is not enough light, too much nitrogen fertilizer, improper irrigation, should be transferred to the light, pruning branches. Yellow or brown spots like water stains appear on the leaves, which may be the result of excessive watering and mud spots spattering on the leaves and then exposure.
