Only in this way can we make the writing at home less and be happy. What is the breeding method of mosquito repellent? Is mosquito repellent poisonous? Can mosquitoes be repelled at home?

Culture methods of mosquito repellent:

1. Selection of basin soil

Mosquito net vanilla grows very fast in the seedling stage, so changing pots is more frequent in the seedling stage, using peat soil: vermiculite: perlite with a proportion of 6:2:2 nutrient soil, of course, it is easier to buy seedling soil directly.

After transplanting, the adaptability of the plant is very strong, the soil can be used freely, and the trunk of the biennial plant is Lignified, which can be pruned and shaped.

2. Temperature control

The growth temperature of mosquito net vanilla is 10: 25 ℃, it can survive the winter safely above 0 ℃, and lemon fragrance can be emitted only when the temperature is above 15 ℃. The higher the temperature is, the more the aroma is, the better the aroma is and the better the mosquito repellent effect is.

3. Light regulation

Mosquito net vanilla like shade, can not grow in direct sunlight, or bask for too long, summer shade, family potted plants are generally kept indoors, pay attention to ventilation.

4. Water and fertilizer

After each change of basin, it should be watered once and fertilize (thin fertilizer) after slow seedling for 15 days. Spring is the peak period of growth.

Watering should pay attention to the principle of wet between dry and dry, high temperature in summer, less watering, no fertilization. It is beneficial to the development of root system and improve the disease resistance.

Breeding methods of mosquito repellent grass:

1. Cutting

It mainly uses adult plant pruning cuttings, cut off the side branches of mosquito net vanilla every spring and autumn, cut into 5 cm segments, soak them with carbendazim for 15 minutes, obliquely insert them on vermiculite or river sand seedling bed, and cover them with film and sunshade net.

Spray water 3-5 times a day, generally about 10 days to take root, 20 days when the new buds grow to about 5 cm can be transplanted on the basin.

2. Sowing seeds

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 in a small pot 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.

Pest control of mosquito repellent:

If the maintenance is improper, there will be root rot, stem and leaf decay, leaf shrinkage, or black spots, serious shrinkage of the whole plant.

It is usually too frequently watered, too humid, or poorly ventilated when the temperature is too high, or the seedling density is too high.

Prevention and control measures:

Spray fungicides such as carbendazim or carbendazim, but not frequently, twice a week.

Note:

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 fall off soon, most of them are caused by insufficient light and too much watering, and this phenomenon can also be seen 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 watering, 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.

Culture methods of mosquito repellent vanilla

1. Soil. Mosquito net vanilla (mosquito repellent grass) likes neutral and acidic soil and is generally fertilized 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. Mosquito net vanilla (mosquito repellent grass) is the most suitable growth temperature of 10-25 ℃, can safely survive the winter above 0 ℃, and can normally emit lemon fragrance 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. Light. Mosquito net vanilla (mosquito repellent grass) likes shade and is not resistant to strong light when growing, especially in summer. It can be planted under trees or in shade. Family potted plants are usually sprouted indoors.

The culture method of crab claw orchid, the points for attention of crab claw orchid culture introduce that it will take a certain amount of energy to cultivate each kind of plant well, and it will indeed take a lot of effort to cultivate good crab claw orchid. First of all, we should pay attention to its habits and characteristics. Secondly, it is planted according to its characteristics. The following is the editor collected and summed up some information for you, let's learn about his breeding methods. Crab claw orchid, also known as Christmas cactus, is a plant of the genus Cactus of the cactus family. It is also named because its nodal stems are connected in the shape of crab claws. Its flowers grow at the top of the stem, and the perianth is opened and rolled back. And its flowers also have purple, red, yellow, white, orange and two colors, which is of great ornamental value. Breeding methods and precautions lighting: in summer, we'd better put it in a semi-shaded place for maintenance, or we can give it shade, so that its leaf color will be more beautiful. And in the spring and autumn, because the temperature is not very high, at this time we can give it enough direct sunlight, which is more conducive to its photosynthesis accumulation and nutrients. In winter, it needs to be maintained in a bright light place indoors. Usually the best indoor maintenance is to be placed near the doors and windows in the southeast in order to receive light, and we had better move to outdoor maintenance after a month, otherwise its leaves will become yellow and thin, and the branches will be in a state of overgrowth. Fertilizer and water: its drought tolerance is very strong, but it can grow well even in a dry environment, but it does not mean that it is not watered or fertilized. Its roots are afraid of water stains, so if it accumulates water in the flowerpot or if you water and fertilize it too frequently, it is easy to cause its roots to rot. Therefore, the principle of watering and fertilizing him is to follow the dry and wet, no dry, no watering, and then watering thoroughly. Avoid getting the plants wet when fertilizing and watering. In spring and autumn, it is the peak season for its growth, so it is necessary to give it adequate fertilizer and water management, and it will be dormant at this time of high temperature in summer, so there will not be too many requirements for fertilizer and water, and we even have to control fertilizer and water for him. We should often spray water on the leaves to reduce humidity. Winter is also its dormant period, and it is also necessary to do a good job in fertilizer and water control. Temperature: the most suitable temperature for growth is between 15 and 32 degrees, and it is afraid of high temperature and warm weather, it will enter the dormant period under the high temperature in summer, and the overwintering temperature also needs to be kept above 10 degrees. If it is lower than 7 degrees, it will also be dormant. Once the ambient temperature is close to 4 degrees or even lower, it will die from frostbite. Although it is troublesome to raise a plant, you will find a lot of fun after careful aftertaste. It can not only cultivate sentiment, but also beautify our home life and improve our taste of life.
