How to plant morning glory seeds?

Morning glory is an annual trailing herbaceous flower of the genus Petunia in the petunia family. It likes a mild climate, sufficient sunlight and a ventilated environment of humidity, and it is also very adaptable to the soil. It 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. Let's take a look at how to grow morning glory seeds.

Seed propagation 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, properly treat them with sulfuric acid after 4-6 hours, sprinkle them in the soil and cover them with thick soil, about 1 cm, keep the soil moist, germinate in about 5-6 days, and transplant after two long leaves.

Petunia flower pot planting and sowing

Petunia flowerpot planting should be in early April, with ordinary culture soil and plain sandy soil each half, install No. 2 tube pot (inner diameter 13 cm), each pot sow 4 meters to 5 meters seeds. Because the seed coat is thicker and sprouts slowly, it can be carved a little bit in the upper part of the hilum with a knife. Keep 25 ℃ after sowing and germinate about 7 days. Observe the transplanting of two cotyledons when the seedlings are flat, and the whole block can be removed from the pot to separate the seedlings with 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 morning glory, never touch the main root, the seedlings should be small, early, the bigger the better.

Transfer and planting of morning glory

Morning glory seedlings grow 6 to 7 leaves are about to extend the vine, the whole block out, replaced with billet basin (inner diameter 24 cm) colonization, basin soil to use fertilizer culture soil, and apply 50 grams of hoof as base fertilizer. Water thoroughly after planting. Wait for the basin soil to be implemented, insert a 1-meter-long thin bamboo pole straight into 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.

Seed retention method of morning glory

Good varieties of morning glory must keep good seeds, and the seeds should be classified and marked when they are ripe in autumn, and should be retained if there are varieties. 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.
