Culture methods of mosquito repellent grass

Mosquito repellent grass is fond of mild climate and fresh environment. Winter is afraid of cold and dry, summer is afraid of heat and dampness. Planting mosquito repellent grass is usually sown and propagated by cuttings. it is better in spring and autumn to sow seeds in clean fine sandy soil, 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 germinate and root in about 1 month at room temperature of 19 ℃. Then, the seedlings were raised in a small pot on the ordinary culture soil, preferring neutral and acidic soil, and white roots appeared from the bottom hole of the basin when the seedlings grew strong. Some broken hooves were padded under the fertilized culture soil as base fertilizer and planted in chrysanthemum bucket pot. Mosquito repellent grass grows fast and needs to change the basin to increase soil and fertilizer once a year.

Mosquito repellent grass likes light, except for a little shade in summer, there should be direct sunlight in autumn, winter and spring. Like temperature and water, 10-23 ℃ is the suitable growth temperature, below 6 ℃, the temperature above 32 ℃ is disadvantageous to the growth, once watered once every 356days, but can not accumulate water. It is beneficial to the development of root system and improve the disease resistance. Family cultivation can also apply a small amount of cake fertilizer and rice water and so on. The humidity is too high, the temperature is too high, at the same time, poor ventilation or excessive seedling density, improper management caused by root rot or stem and leaf rot, leaf shrinkage, black spots, and then the whole plant shrinks. It is worth noting that patients with respiratory diseases at home should use it with caution.

Culture methods of mosquito repellent grass

How to raise mosquito repellent

Mosquito repellent was first introduced into geranium by Dutch geneticist Dick using gene fusion technology, and the species has the wonderful effect of mosquito repellent. Then spread to Japan, Australia and other places, became a natural mosquito repellent plant, deeply loved by the majority of consumers.

Mosquito repellent grass is naturally fond of mild and cool environment, and its most suitable growth temperature is about 15-20 ℃. It is very afraid of severe cold and heat, so it is necessary to pay special attention to temperature changes in summer and winter.

Breeding methods of mosquito repellent grass

Mosquito repellent grass is usually propagated mainly by sowing and cutting. Sowing and reproduction is usually carried out in early March, and the specific operation step is to sow the seeds directly into the clean sand, place them for about 4 hours, and then pour water and place them in a warm and bright environment of about 20 degrees Celsius until they germinate naturally. The period of germination is about 1 month, during which time the soil should be kept moist. The seeds should be divided into different planting operations after sowing and germination, and the broken hoof base fertilizer should be added under the potted soil. The method of cutting propagation is no different from that of other plants.

Culture methods of mosquito repellent grass

Change the basin: the growth rate of mosquito repellent grass is very fast, so it is necessary to change the basin once a year to ensure its normal growth. It is best to change the basin between February and March, and select the initial stage of its growth. The specific operation steps are to prune the luxuriant branches and leaves, leaving only three lateral buds at the base. Then take the mosquito repellent out of the basin, remove the old roots, and finally put it into the new culture soil with fertilizer. Usually new shoots will grow after a month, and then fertilized every other week, mainly with thin organic fertilizer liquid. The room can be removed around the end of April and blossom one after another. In summer, to avoid excessive direct sunlight, and to maintain the humidity of the environment around the plant, you can choose to spray water to cool down.

Temperature: the most suitable temperature for mosquito repellent grass is 10-25 ℃. In winter, as long as the temperature is above 0 ℃, it can safely survive the winter. In its growing period, the temperature above 15 ℃ can release the fragrance for mosquito repellent. The release of its fragrance increases with the increase of temperature.

Lighting: mosquito repellent grass prefers a cool environment, but it can't stand direct sunlight for a long time. Therefore, in the summer, we should pay attention to the changes of direct sunlight, it is best to put in the shade out of breeding.

Is mosquito repellent useful? the culture method of mosquito repellent grass

Summer is coming, people's most worry is how to drive mosquitoes, will think of various ways to drive mosquitoes, mosquito repellent grass in plants can also drive mosquitoes, so mosquito repellent grass useful? Next, let's talk about the breeding methods of mosquito repellent grass.

Is mosquito repellent useful?

Mosquito repellent is a mosquito repellent grass cultivated by geraniums native to Africa by Dick, a Dutch geneticist, by introducing citronellal into citronella by gene fusion technology. Pelargoniaceae is a kind of volatile plant. Under normal circumstances, the plant volatilizes its own odor molecules through photosynthesis. Citronellal itself has the outstanding effect of mosquito repellent, which plays a role in many mosquito repellent products. It follows the odor molecules of geraniums into the air to ward off mosquitoes and purify the air.

Mosquito repellent grass, also known as mosquito repellent grass, succulent stem tips, alternate leaves, wavy obtuse serrated edges, smooth leaves. The stomata are large and densely distributed on the lower surface of the leaves, which has a strong function of releasing aroma and emitting lemon fragrance all the year round, which not only has the effect of repelling mosquitoes, but also purifies the air. Mosquito repellent grass can survive above-3 ℃. The higher the temperature is, the stronger the aroma is, the better the mosquito repellent effect is, and it can also be cultivated with bonsai. According to the experimental monitoring of the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, when the mosquito repellent leaves reach 15, the protection rate can reach 97.8%, and the effective mosquito repellent range of each mosquito repellent grass can reach 15-20 square meters. Mosquito repellent performance and environmental protection performance have reached the international leading level.

So is it useful to ask mosquito repellent? The answer is yes, but due to the small concentration of volatile gas, the mosquito repellent effect of only a few pots of mosquito repellent grass is not very significant, and it is impossible to rely on it to completely stay away from mosquitoes, so people's expectations of mosquito repellent grass should not be too high. after all, the mosquito repellent effect is not as fast as chemicals.

In addition to mosquito repellent, plants such as jasmine, evening primrose and peppermint also emit a special smell that keeps mosquitoes away.

Mosquito repellent culture methods:

1. Soil: mosquito repellent vanilla prefers organic fertilizer, soft and moist soil, and avoid clayey soil. When the root system of mosquito repellent vanilla is developed, larger flowerpots should be used to maintain more water and more organic matter capacity. Mosquito repellent vanilla requires a certain acidity of the soil. PH5.5~6.5 is the best range for its growth, so it is necessary to prevent soil Alkalization.

2. Fertilization: foliar fertilization of mosquito repellent incense should be avoided so as not to affect the release of citronellal or cause fertilizer damage.

3. Temperature: mosquito repellent vanilla can survive at 0: 35 ℃ and grow at 10: 30 ℃. The best growth temperature is 15: 25 ℃. When the temperature reaches 35 ℃, it will enter the semi-dormancy period. Therefore, the maintenance of mosquito repellent incense avoid low temperature preservation and room temperature is too high.

4. Ventilation: mosquito repellent vanilla likes ventilation. It is best to put it on a well-ventilated windowsill and balcony when it is not in use during the day. Good ventilation can reduce the occurrence of diseases and prevent decay.

5, lighting: mosquito repellent vanilla like light, it is best to accept 1-2 hours of direct sunlight every day, but do not expose to the sun. Keep summer in the shade. Mosquito repellent vanilla is more resistant to dry air, afraid that the air is too wet, high humid environment is easy to cause disease, but also easy for mosquito repellent vanilla to enter dormancy and stop growing.

The culture methods of mosquito repellent should pay attention to the following points:

1. Soil, mosquito repellent grass likes a sunny and well-ventilated environment, especially afraid of stagnant water in the soil, and loose sandy loam is suitable to prevent alkalization caused by improper watering.

2. Lighting: it should be placed in the sun during the day, and proper shade should be paid attention to in the hot sun.

3. Reproduction: sowing and cutting are often used, and the latter has a high survival rate in spring and autumn.

4. Changing basin and pruning: mosquito repellent grass grows fast and needs to be fertilized once a year, usually in early spring from February to March. First, it is strongly pruned, leaving only three basic lateral buds per branch, and then take off the basin to remove the surrounding old and decaying roots.
