Culture method of morning glory

Morning glory is a very common flower plant in daily life, also known as morning glory, trumpet flower, gluten horn, morning glory, Qin Niangzi, etc., Corolla trumpet-like, colorful and beautiful, in addition to cultivation for viewing, seeds are commonly used traditional Chinese medicine, with the effect of purging water conservancy urine, phlegm and killing insects. Let's take a look at the breeding methods of morning glory.

Growth habits of morning glory

Morning glory is a kind of flower with strong natural nature. it likes mild climate, sufficient sunlight and ventilated environment of humidity. morning glory also has strong adaptability to soil, is more resistant to drought, salinity, and is not afraid of high temperature and heat. It is a deep-rooted plant, and the soil should be deep. But the big seedlings of morning glory are not resistant to transplantation, and friends who like morning glory must pay attention to this.

Propagation methods of morning glory

Morning glory is usually propagated by seeds, and the sowing time is in spring and summer. It is suitable for sowing and planting at 20-25 ℃, and can blossom in summer and autumn. When sowing, soak the seeds in warm water, soak them in warm water for 4 to 6 hours, properly treat them with sulfuric acid, sprinkle them in the soil and cover them with thick soil, about 1 cm, keep the soil moist, germinate in about 5 to 6 days, and transplant after two long leaves.

Culture method of morning glory

1. Planting: morning glory can sow 4-5 seeds in each pot and break a little heavy skin. Keep the temperature at 25 ℃ and germinate in about 7 days. When the leaves grow out, they can be transplanted to separate the soil from the bracket. When planting morning glory, we should first choose the soil with good drainage, give proper ventilation and sufficient sunshine, irrigate and apply rarefied fertilizer once a month to control the degree of nitrogen fertilizer and prevent the stems and leaves from being too luxuriant.

2. Planting: when the seedlings grow out of 6 to 7 leaves and are about to extend the vine, the whole block is protruded and planted in a billet basin (24 cm in inner diameter). The basin soil should be fertilized and cultivated, and 50 grams of hooves should be applied as base fertilizer, and water should be watered after planting. Morning glory is not afraid of heavy fertilizer, you can use horseshoe, cooked hemp residue and so on as base fertilizer. The development of the root system of morning glory needs temperature, and it is better to absorb heat with black basin than with red basin.

3. Soil: morning glory pots should be planted in early April, with half of ordinary culture soil and half of plain sandy soil. When making a pot, the lower end of the main root will be removed 1 cm, with ordinary culture soil planted in the No. 2 pot, one plant per pot. Pay attention to the open field transplantation of Petunia, never touch the main root, the seedling should be small, should be early, the bigger the better.

4. Water and fertilizer: the cultivation soil with good drainage should be selected for the cultivation of morning glory, which should be given to an environment with sufficient sunshine and good ventilation. During the growth period, the surface of the basin soil should be irrigated slightly dry, and once every half a month, the nitrogen fertilizer should not be too much, so that the stems and leaves should not be too luxuriant, and the potted plants should be supported by pillars.

5. Pick the heart: wait for the basin soil to be implemented, insert a 1-meter-long thin bamboo pole in the center of the basin. Then use about 3 meters of lead wire, one end of the soil surface wrapped around the bamboo pole, and then spiral upward from the basin mouth to form a large and small symmetrical tower-shaped spiral frame. The upper end of the wire is fixed at the top of the bamboo pole. Morning glory is a left-handed plant, the spiral direction of the lead wire must be in line with the habit of morning glory winding to the left, when the main vine climbs along the lead wire to the top of the pole, pick the top. The lateral vine pinches every 6 to 7 leaves, which can make the flowers big and blossom continuously.

6. Diseases and insect pests: morning glory is mainly prone to white rust, the main sites are leaves, petioles and tender stems, and the damaged leaves have light green spots on the leaves at the initial stage. In this case, the diseased plants can be pulled out and destroyed in time to reduce the infection of seeds. Leave disease-free seeds as propagation seeds and disinfect seeds before sowing to avoid rotation with plants of Convolvulaceae. Spraying 1% Bordeaux solution or 50% Phytophthora 500 times solution at the initial stage of the disease, spraying once every 10 to 15 days has a better control effect.

7. Keep seeds: good varieties must keep good seeds, and seeds should be collected and classified and marked and preserved when they are mature in autumn. If there is a variation, it should be retained. After selecting the female and male parents, the morning glory will cut off the upper end of the bud at dusk the day before flowering, then remove the stamens and wrap them with wax paper bags. The next morning, remove the wax paper bag, use the stamens of the male parent for artificial pollination, and then wrap it with a wax paper bag. After one or two weeks, the wax paper bag can be removed, but the pollination bag must be marked and recorded. In the following year, all the hybrid seeds should be planted well, and the fruit can be seen after flowering, from which the role of various genetic factors can be studied.
