How to plant Simmonia and its planting methods and matters needing attention

Simuli is a kind of plant that likes temperature and light, which is distributed in many parts of our country at present. Simal has a high ornamental value, mainly to flowers, and is very popular with consumers in the market at present. Therefore, it attracts a lot of people to plant. However, before breeding, most people must want to know its planting technology in advance.

How to grow Himalayan

1. Soil. The requirement of Simuli on soil is not very high, so it is best to choose micro-acid fertile sandy loam with good water retention and drainage, if the plant will grow poorly in the soil with long-term stagnant water.

2. Temperature. Simuli likes to grow in an environment with high temperature, high humidity and plenty of sunny. generally speaking, the suitable temperature for growth is 15-30 degrees. The cold tolerance of the plant is not good, and the temperature should be kept above 8 degrees in winter.

3. Light. Simasmine is fond of hot, humid, ventilated and breathable environment and needs sufficient light. Jasmine is afraid of the cold, and the potted plant in the south can be cultivated outdoors to survive the winter. In the north, it is necessary to keep warm in autumn and winter, and move indoors and put it toward the south. If the light is strong, the branches are strong, the leaves are dark green, the flowers are many and fragrant, and if the sun is not enough, the flowers are sparse and not fragrant. The stronger the light is, the more developed the root system of jasmine is, the stronger the plant growth is, and the stronger the stress resistance is.

Planting methods and matters needing attention of Himalayan

First, planting techniques:

The seedlings can be raised in a greenhouse or geothermal seedbed, the seeds are removed and sown on the seedbed, the ground temperature is controlled at about 20 ℃, and the ground temperature is stopped after emergence. The sowing amount is about 300 grams per square meter of seedbed. When there is a pair of true leaves, the seedlings are transferred once, and a single plant becomes a seedling. 5-7 days before planting, cool down and release the strong wind to refine the seedlings, and plant after the final frost. Can also be on demand in the small arch shed, do not transplant, a seedling, according to 7 cm x 7 cm interval on demand. After growing up to a certain extent, you can go into the basin.

2. points for attention:

Potted Simmonia should generally change the soil once a year. When changing the basin, part of the old soil and residual roots around the root system were removed and replaced with new culture soil to improve the soil aggregate structure and nutrients, which was beneficial to the growth of Himalayan. When you change the basin, water it thoroughly as if it were on the basin, so that the root soil can be connected closely and the growth can be restored. Himalayan should be pruned before changing the basin, leaving only about 10 centimeters for the branches born last year, and cut off the diseased and withered branches and overdense and thin branches. During the growing period, the old leaves that are too dense are often removed, which can promote the germination of axillary buds and the emergence of new branches and long buds.

Why is Himalee so fat and watery?

1. Watering: Simone is not resistant to drought, but avoids stagnant water. In rainy season, it is necessary to dump stagnant water in the basin in time, otherwise the leaves are easy to turn yellow. In summer, hot and sunny days should be watered twice a day, once in the morning and evening, if the leaves are found to curl and droop should be sprayed on the leaves to promote growth, the rainy season should often loosen the soil, so that there is no water in the basin. Water is watered every few days in spring and autumn. Winter should keep the basin soil moist, too much watering, the roots will be black and rotten, leaves withered and yellow, shedding.

2. Fertilization: the high temperature season in midsummer is the peak period for the growth of jasmine, applying more organic fertilizer and phosphorus and potassium fertilizer, such as peanut cake powder, bone powder, calcium superphosphate and multi-element flower fertilizer, twice a month. Jasmine often has luxuriant branches and leaves but does not blossom in summer, the main reason is that too much nitrogen fertilizer is applied, resulting in the growth of branches and leaves. In such a situation, it is necessary to control fertilizer and water, apply more phosphorus and potassium fertilizer, and promote the gestation of flower buds. At the same time, we should pay attention to move the jasmine to a place with plenty of sunshine and good ventilation.

Diseases and insect pests of Simmonia officinalis and its control

Xi jasmine often has borer larvae and shell insects, red spiders, the most serious from July to September, often eat flower buds, can be sprayed with almighty powder or permethrin plus water 200 times, once every half a month, that is, no diseases and insect pests should be sprayed, so that the spraying time should be 9 am and 4 pm on a sunny day, and should not be sprayed in the hot sun at noon to prevent drug damage.

Simone must choose the right soil when planting, and then ensure its light and temperature, so that it can grow well. In the later stage of planting, it is also necessary to strengthen the management of fertilizer and water, and timely prevention and control of diseases and insect pests is also a key point.
