Detailed explanation of planting method and matters needing attention of lemon flower

The flower language of lemon flower is loyal love. In recent years, many people like to plant some potted lemons indoors, which are both edible and beautiful. But lemon flowers need better care than other flowers, and it is often difficult to bloom if they are not properly managed. So how to raise potted lemons? What are the basic precautions? Let's take a look at how lemon flowers are planted in the flower language of various flowers.

1, seedling and pot culture

Generally, southern lemons are mainly propagated by grafting, while northern lemons are mainly propagated by cutting. In order to save trouble, you can also buy grafted seedlings directly. Lemon roots have high requirements for water, nutrients and soil. Potted soil should be made into water-permeable, breathable, water-retaining and fertilizer-retaining, slightly acidic culture soil. The time of loading and changing pots can be in autumn or early spring, which can be flexibly mastered according to the local climate.

2, light and temperature

Lemon is a light-loving plant, and its optimum growth temperature is 23-29℃. Exposure to the sun can easily lead to stunting. Growth will stop when it exceeds 35℃. It should be shaded properly at noon in summer, and it will freeze at MINUS 2℃. Pay attention to keep warm and cold in winter. In the north, lemon potted plants have to be moved indoors to survive the winter safely.

3. Water and fertilize

Lemon needs more water in its growth and development, but too much water is not easy to rot its roots. Generally speaking, spring is the time when the buds germinate and the leaves unfold. The pregnant buds are in full bloom and should be watered properly. In summer, with strong sunlight and high temperature, more water is needed. But it should be timely and appropriate, otherwise it will cause fruit loss. Autumn is the period when autumn shoots grow and fruits expand rapidly, so there must be enough water. The late autumn and early winter are the stage of flower bud differentiation, and the basin soil is dry.

Lemons like fertilizer. In the growing period, in addition to applying sufficient base fertilizer on pots and changing pots, we should also adhere to the principle of applying thin fertilizer frequently. The frequency and amount of fertilization should be determined according to the growth and phenology. If liquid fertilizer is applied, it is best to use fully fermented cake fertilizer and water, and the ratio of cake to water is 1: 200. The soil in the north is alkaline, so ferrous sulfate can be added to the fertilizer solution to make a slightly acidic nutrient solution. Lemon plants should be topdressing many times before flowering and after fruiting, applying multi-element flower fertilizer once a month and spraying flower nutrient solution once every half month to ensure that the fruits are not easy to fall off and have bright colors.

4, plastic pruning

Potted lemons are usually replaced in spring. At this time, the inner branches, diseased branches and overgrown branches of lemon can be cut off. In summer, the branches without fruits can be pruned properly, and the branches inclined in the middle and upper part of the crown can be shortened to prevent them from robbing the fruits of nutrients; In winter, the dead branches, short weak branches and long branches are cut off on the principle of deleting dense and keeping sparse, removing weak and keeping strong.

5. Promote flowers and protect fruits.

Lemon is a tree species that blooms and bears fruit in all seasons, while potted plants in the north mostly bloom and bear fruit in spring. Therefore, after the autumn shoots stop growing, water should be controlled. When the two sides of the leaves begin to roll in, water them moderately to promote flower bud differentiation. Pay attention to fertilization in the basin and spraying fertilizer on the leaves to cultivate strong mother branches. After fruit setting, according to the size of the plant, leave a few or dozens of strong fruits without pests and diseases, pick the remaining flowers when you see them, and concentrate the nutrition on the young fruits.

7. Change pots and soil

Potted lemons must be turned over in March-April in spring. If the flowerpot is too small, you can change it to a suitable flowerpot. If the flowerpot is still suitable, the original flowerpot can be replaced with new soil, and the base fertilizer should be applied when changing the soil.

Summary: A good potted plant needs the careful care of the planter, so does planting lemon flowers. In daily watering, flowers should be kept warm and cold in winter and shaded in summer.

Breeding methods and matters needing attention of iris tectorum

Propagation method of iris tectorum

Sowing propagation

Autumn sowing in September is the best, with 700 grains per gram. The suitable temperature for germination is 13 ~ 16℃, and it germinates in 12 ~ 15 days after sowing, and it takes about 100 ~ 16 days from sowing to flowering.

cutting

In May and June, the sprouted branches at the base of plants are cut off and inserted into peat to keep the air moist. Rooting after 15-20 days, with high survival rate.

fissiparity

Usually after flowering. New shoots with roots or rhizomes with adventitious roots growing from lateral branches can be cut off, potted directly and restored in semi-shade.

Matters needing attention in iris cultivation

temperature

The suitable germination temperature of iris tectorum is 18-2 1℃, and it germinates in the dark for 7- 10, and the growth temperature is13℃. After sowing,14-/kloc-0. If the temperature is at the time of sowing, the soil temperature at the growth stage of pansy seedlings is 15-24℃. The lower the temperature, the slower the plant growth and the stronger the plant.

illuminate

After planting iris, cover the seeds with vermiculite, keep the soil temperature at 18-24℃, and keep the medium moist. Bacon doesn't need light before it grows, and it usually emerges in 7- 14 days.

water

Let the soil dry thoroughly before watering, but avoid permanent wilting of plants, which is beneficial to the root growth of pansy. The pH value of the soil should be kept at 5.5-5.8, and some nitrogen fertilizer or potassium nitrate should be applied alternately.

Planting method of bodhi tree | Matters needing attention in planting bodhi tree

Bodhi trees have moderate resistance to sulfur dioxide and chlorine, and strong resistance to hydrofluoric acid, which is suitable for greening in polluted areas. At the same time, it is an excellent ornamental tree species with swollen branches, tall trees, lush foliage and broad crown, which is suitable for courtyard street greening. In addition, bodhi tree is a traditional Chinese medicine for treating asthma, diabetes, diarrhea, epilepsy and stomach diseases. Today, I will briefly introduce the planting methods and precautions of bodhi trees for you.

Planting method of bodhi tree

For seed propagation, it is necessary to select strong mother plants that are more than 10 years old, collect the seeds when the fruits are red and black in1month, knead the collected fruits repeatedly, remove the meat residue and dander, take out the seeds, and sow them after being slightly dried. Generally, sand beds are used for sowing seeds. Before sowing, slightly compact the bed surface with small wooden boards, level the bed surface, and evenly scatter the seeds on the bed surface. When sowing, seeds should be prevented from overlapping into small balls, and each seed should be scattered on the bed surface as much as possible.

After sowing, cover the seeds with a thin layer of soil with a fine screen, preferably just the seeds. After sowing, build a shade shed with straw or sunshade net to reduce the evaporation of water in the seedbed and keep the bed surface moist. At the same time, chemical substances that kill ants are scattered around the sand bed to prevent the seeds from being hurt by ants and crickets when they germinate. Because the seeds of bodhi trees have no dormancy habit, they can germinate and emerge in about 10 days after sowing, and the seeds will germinate one after another.

When the germination is about half, uncover all the straw, shade it properly, and pour enough water every morning and evening. When the seedlings grow to 24cm, they should be transplanted into 10cm 12cm nutrient bags filled with soil (topsoil with high humus content) in advance for culture. After the seedlings are transplanted into nutrient bags, they should be shaded by shading nets and watered in the morning and evening. After the seedlings resumed growth, the roots were watered with 0. 1% urea aqueous solution and Norwegian compound fertilizer every 7 days.

Sprinkle a small amount of water after root irrigation (sprinklers can be used in qualified nurseries), which is beneficial to the seedlings to absorb water and fertilizer. When the seedlings grow to about 15cm, the concentration of water and fertilizer can be increased to 0.2% 0.3%. At the same time, take corresponding measures to prevent the occurrence of diseases. When the seedlings grow to 3050 cm, they can leave the nursery. Bodhi branches are also easy to survive by cutting. A robust 8 15-year-old mother plant can be selected in spring or autumn.

Branches with full axillary buds were selected from the mother plant and cut into cuttings (diameter about 0. The semi-lignified part is about 65438 05 cm, which is used for cutting propagation. The row spacing of cuttings is 5cm 10cm, and the cutting depth is about 3cm. After cutting, put on a small bow shed, cover it with white plastic agricultural film, and keep the front and rear ends ventilated. Spray water several times a day to ensure the shed.

After cutting, spray the cuttings with 0. 1.25% 0.2% broad-spectrum bactericide (such as chlorothalonil and carbendazim) solution. ) once every 7 days to prevent cuttings from rotting under high temperature and high humidity. Roots can grow in about 10 days. Bodhi trees can also be cut with big branches. Strong branches with a diameter of 65,438+0,065,438+0.5 cm and a length of 65,438+0.52.5 m can be cut and buried in the soil for 2030cm, and can take root after 20 days.

Matters needing attention in planting bodhi tree

Bodhi seedlings are easily infected with damping-off and black spot. Chemical control can be carried out by spraying 80% mancozeb wettable powder 0. 167% solution, or 60% carbendazim and 75% chlorothalonil 0. 125% solution, or spraying two mixed solutions every 7 days 1 time, three times in a row.

Aphids and moth larvae harm terminal buds and young leaves, especially aphids, and often cluster on the back of young leaves of seedlings to feed on mesophyll. Chemical control can be achieved by spraying 90% trichlorfon 0. 125% solution or 40% omethoate 0. 1%0. 125% solution on the front and back of young leaves.

Cultivation methods and matters needing attention of Sabina vulgaris

Sabina vulgaris, a light-loving, shade-tolerant, cool and warm climate tree species. The landscape of Sabina vulgaris can last for hundreds of years, with picturesque posture, which can be well appreciated all year round. Its tree shape is particularly beautiful, with many branches and leaves, and the leaves are like green lids, which is very magnificent. It can be a landscape by itself. So how to breed, what should we pay attention to? Let's have a look!

1. Water

Sabina vulgaris is drought-resistant, but it is afraid of water accumulation, so it should not be too wet when watering. If it is dry, there is no need to water it. You must see that it is dry and doesn't need watering when it is wet. In the rainy season, we must be careful not to have too much water in the basin. When the temperature is particularly high in summer, you should water it in the morning and evening. As long as you keep the soil in the basin moist, you should always spray water on the leaves to make them greener.

fertilize the soil or land

The cypress pile landscape can't be fertilized too much, which makes it grow white, and finally affects the shape of the whole tree, making it particularly unsightly. Generally, it is enough to apply a little thinner fertilizer two or three times a year from March to May, and 1 or twice in autumn, so as to keep the leaves very light green and dense and grow stronger.

Turn the basin over correctly

Because it grows slowly, it can only be turned once every three to four years, usually in the rainy season. Because it prefers moist and drained soil, it can properly remove some old roots, replace half of the permanent soil in advance, and add a little fertile and loose sandy culture soil when turning over the basin. If it is a big tree, the old roots need to be pulled out before transplanting. It is best to keep the crown in its original position at all times, usually in late autumn or spring. If the temperature is too high, the survival rate will be very low.

Proper pruning

When plants enter dormancy in winter, we can cut off some diseased, unhealthy, diseased or too dense branches so that new branches can grow better next year.
