How to grow morning glory

1. First of all, prepare the culture soil, soak the seeds in warm water, treat them moderately with sulfuric acid after 4-6 hours, then sprinkle them in the soil and cover them with soil. Then sprinkle a little water on it to keep the soil surface moist.

two。 Waiting for seeds to germinate, the temperature needs to be controlled at 15-20 degrees. The temperature is too low or too high, which will be disadvantageous to the growth. If the temperature is lower than 10 degrees, the seeds are not easy to germinate, and if the temperature is too high, the buds are easy to rot.

3. When the buds grow into small seedlings with 5-6 leaves, you can change the basin to a slightly larger basin, add some organic fertilizer to the soil, sprinkle water properly, and pay attention to ventilation, waiting for the new leaves to grow.

4. In the process of morning glory growth, if the leaves turn yellow, it is mostly caused by lack of fertilizer, so it is necessary to apply fertilizer properly. When fertilizing, the fertilizer can be turned into liquid and sprayed directly on the surface of the leaves.

5. The first leaf of the vine gives rise to axillary buds, and the second and third leaves send out buds. When the bud differentiates, you can pinch off some of it, which is more conducive to flowering.

Morning glory planting habits: like warm and sunny environment, not cold-resistant, can withstand drought and barren, and grow best in humid, fertile, well-drained neutral soil. For short-day plants. Flowers usually open early in the morning and wither and wither before noon. It is an annual twining herbal flower. Cultivation management: direct broadcast on the open field in spring. The germination temperature was above 15 ℃. If sowing in the open field, it should be transplanted in the seedling; if sown in the flowerpot, when the seedling has 4-5 true leaves, change it into a pot with a diameter of 20-25CM and set up a bracket. If there is no bracket, pick the heart when the main vine grows 5-7 true leaves, leave 2 technical vines in the middle and lower part after the occurrence of axillary buds, and divide the rest, so that each pot can produce more than 10 flower buds at the same time, fertilize and water at the right time, and should be drained in time in the rainy season. 1. Raising seedlings: the germination temperature of morning glory is 20: 30 ℃. Generally, the seeds are sown at the end of April and the beginning of May (the south can also be in advance). The seeds are planted in the fine sandy soil seedbed according to the variety, and germinate in about 10 days when the humidity is moderate. After about 10 days, the cotyledons are fully open. When the true leaves just germinate, they should be transplanted into a small pot, the seedlings are weak too early and the roots are injured too late, which is not conducive to future development. The small basin should be marked with the variety. 2. Planting: after the seedlings in the small basin grow two or three true leaves, the root system has developed well, it can be planted in the middle basin, and the base fertilizer can be added in advance. As Mr. Mei said, morning glory is not afraid of heavy fertilizer, and horseshoe and cooked hemp dregs can be used as base fertilizer. The development of the root system of morning glory needs temperature, so it is necessary to turn the basin frequently to make the sun shine evenly and make the root system develop completely. 3. Heart-picking: after the true leaves of morning glory grow three or four, the center begins to grow vines, which should be removed. After picking the heart for the first time, there are branches between the axils of the leaves, and after the branches give birth to three or four leaves, they pick the heart again and combine with plastic surgery at the same time. The fertilizer used is similar to that used for chrysanthemums. Be careful not to stain the leaves (including cotyledons) with fertilizer, water and mud, so as not to fall off the leaves. As soon as the vine grows, it enters the flowering stage (usually one month after planting). Ideally, the first leaf of the vine produces axillary buds, and the axils of the second and third leaves send out buds. After the bud is formed, the stipules of the bud can be removed to facilitate the development of the bud. In order to ensure an adequate supply of nutrients and produce large and gorgeous flowers, you can also get rid of some buds and cultivate single flowers, just like cultivating a variety of chrysanthemums. After blooming, you should pick off the residual flowers so as not to make them as children, so as not to affect the nutrition of the next batch of flowers. Of course, after three or four batches of flowers bloom, axillary buds grow, which is difficult to control. General varieties can be planted on the ground, while good varieties are prepared to remain. 4. Keep seeds: good varieties must keep good seeds, and the seeds should be classified and marked after they are ripe 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. How to grow morning glory? the planting method of morning glory

Morning glory is generally sown in spring, there is no need for budding, there is no requirement for soil, of course, if you have nutritious soil on hand, or ordinary flower soil, after sowing, cover soil about 2 cm, and then water thoroughly. Generally, it can germinate in about 3-5 days and blossom in June-July. Morning glory is the most important thing is light, in the case of sufficient light is very easy to blossom. So how to grow morning glory and what is the planting method of morning glory? The following editor makes an introduction for you.

The planting method of morning glory

1. Raising seedlings

The germination temperature of morning glory is 20: 30 ℃. Generally, the seeds are sown at the end of April and the beginning of May (in the south, they can be sown in advance). They are sown in fine sandy soil seedbeds according to varieties, and germinate in about 10 days when the humidity is moderate. After about 10 days, the cotyledons are fully open. When the true leaves just germinate, they should be transplanted into a small pot, the seedlings are weak too early and the roots are injured too late, which is not conducive to future development. The small basin should be marked with the variety.

two。 Colonization

After the seedlings in the small basin grow two or three true leaves, the root system has developed well, so it can be planted in the middle basin and the base fertilizer can be added in advance. As Mr. Mei said, morning glory is not afraid of heavy fertilizer, and horseshoe and cooked hemp dregs can be used as base fertilizer. The root system of morning glory needs temperature to develop, and according to Japanese researchers, it is better to use a black basin to absorb heat than a red one. Should often turn the basin to make the sun shine evenly, so that the root system is fully developed.

3. Pick the heart

After three or four true leaves of morning glory grow, the center begins to grow vines, which should be removed at this time. After picking the heart for the first time, there are branches between the axils of the leaves, and after the branches give birth to three or four leaves, they pick the heart again and combine with plastic surgery at the same time. The fertilizer used is similar to that used for chrysanthemums.

Be careful not to stain the leaves (including cotyledons) with fertilizer, water and mud, so as not to fall off the leaves. As soon as the vine grows, it enters the flowering stage (usually one month after planting). Ideally, the first leaf of the vine produces axillary buds, and the axils of the second and third leaves send out buds. After the bud is formed, the stipules of the bud can be removed to facilitate the development of the bud. In order to ensure an adequate supply of nutrients and produce large and gorgeous flowers, you can also get rid of some buds and cultivate single flowers, just like cultivating a variety of chrysanthemums.

After blooming, you should pick off the residual flowers so as not to make them as children, so as not to affect the nutrition of the next batch of flowers. Of course, after three or four batches of flowers bloom, axillary buds grow, which is difficult to control. General varieties can be planted on the ground, while good varieties are prepared to remain.

4. Shaping and pruning

It is mainly planted on the ground for hedgerow decoration: when the main vine produces 7-8 leaves, 4 leaves are left, and 4 leaves are left after 3 branches are grown. After 9 vines are grown, they are evenly distributed in the fence or wall for binding, and the hedgerows and flower walls can be formed soon.

When viewing in the salt planting room, the flower bracket can be set up in the pot when the seedling is about 6 cm high. You can also leave 4 leaves to pick the heart when you have 7 or 8 leaves, and then leave 1 leaf to pick the heart after growing 3 branches. Make each plant have no more than 9 buds. This can make the plant shape plump and the flowers large. Basket cultivation method can also be used.

5. Leave a seed

Good varieties must keep good seeds, and the seeds should be classified and marked when they are ripe 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.

The above is the article on how to grow morning glory and the planting method of morning glory. Morning glory is generally not prone to diseases after growing up, but some diseases can still occur due to the influence of the cultivation environment. Botrytis cinerea, Fusarium wilt and physiological diseases should be prevented. Carbendazim + streptomycin can be sprayed every 7 to 10 days. Once the disease occurs, the disease should be treated in time according to the actual situation.
