How to raise sweet peas? Cultivation and maintenance skills of fragrant pea with beautiful flower shape

Fragrant peas belong to winter and spring flowers, which are characterized by bright colors and beautiful flowers in winter and spring, and always attract butterflies to dance when they bloom. It has very good ornamental value. The following is about the cultivation methods of fragrant peas, which can be referenced by those who like flowers and plants.

Temperature.

The cultivation temperature of sweet pea should not be too high. Before flowering, the temperature should be controlled at 9 ∽ 13 degrees during the day and 5-8 degrees at night. Otherwise, if the temperature is too high, the plant will bud before it is fully developed, which will affect the plant growth. When flowering, the room temperature rises to 15-20 degrees, which is beneficial to the formation of flowers by replenishing sunshine.

Sowing seeds

The different types of sweet pea varieties sown before November have a large difference in flowering stage. Therefore, different types of sweet pea varieties sown from mid-late November to early December had little difference in flowering stage, and the full flowering period was from late March to the end of April of the following year.

Potted plant

Potted sweet pea can be made of rotten leaf soil, peat, river sand and some organic fertilizer, diluted liquid fertilizer is applied every half a month before flowering, potassium dihydrogen phosphate is applied at the initial stage of flower bud formation, and watering is based on the principle of inter-dry and wet.

Take off the top and leave the main branch

There are 1-2 main branches in each plant. When the seedling height is 15 cm and the main vine is 6 nodes, it is necessary to remove the top of the main vine and retain 2 strong side branches when taking off the top, and all the other side branches need to be removed, otherwise the flowers will be small if there are too many branches, and the nutrient supply of the plant will be scattered.

Florescence management

Pick the blooming flowers in time, which can prolong the flowering period. Fruit is produced after flowering, and the heat formation period of pods in different parts is different, so it is necessary to pick along with ripening.

Indoor maintenance

Indoor pot maintenance should be placed in a sunny position. Keep in mind indoor ventilation to prevent overgrowth or budding. For climbing varieties, scaffolding can be set up, and plants that bloom from December to February to March of the following year can be maintained in a medium-temperature greenhouse, which is conducive to flower growth.

Sweet pea is a very good-looking winter flower, which can blossom in winter and spring. It has a very good planting significance. The above are detailed cultivation and maintenance skills, which you can learn from.

What are the cultivation techniques and propagation methods of fragrant peas? How to maintain and manage after planting?

Sweet pea can be planted all the year round, and its florescence can be divided into three stages, namely, spring flowers and summer flowers. Winter flowers. Planting it should be understood according to his growth habits. Today we will take you to understand how it is planted, how it is sown and propagated, and what is the conservation after planting.

Cultivation techniques of sweet pea:

The growth temperature is 5-20 ℃. If the temperature exceeds 20 ℃, the growth potential will decline, the pedicel will become shorter, and it will die if it lasts for more than 30 ℃. The requirement of soil is not strict, but it grows better in well drained, deep, fertile, neutral or slightly alkaline soil. Sweet pea is rich in color, gorgeous, beautiful flower shape, more petals, double, semidouble, single, wavy, wrinkled, straight and so on. The florescence is from March to June. The fruit matured from July to August. Cultivated varieties: spring flower, summer flower and early flower and so on. It can be used for scaffolding greening, windowsill and eaves greening, and can be potted for cut flowers. In addition, the resistance to harmful gas hydrogen oxide is very strong. The resistance to sulfur dioxide is very poor, so it can be used as a monitoring plant for this gas. Sweet peas like warm winter and summer without hot weather, so they are suitable for biennial flower cultivation. The south can survive the winter in the open field, but it can bear 5%. For the low temperature of C, the north needs to enter the house to survive the winter, the growth is poor below 5C, the suitable temperature for germination is 2OC, the suitable temperature for growth is about 15C, and the fruiting stage is completed before the arrival of midsummer and die. Sufficient sunshine can also tolerate half-shade, excessive shade results in poor plant growth, and the ornamental effect is not good in the areas with more cloudy and rainy days in the growing season. It is required that the ventilation is good, and the bad ones are easy to suffer from insects and diseases. It belongs to deep-rooted flowers and requires looseness and fertility. Wet and well-drained sandy loam does not grow well on dry, thin soil and is not resistant to stagnant water.

Sowing and breeding of sweet peas:

Sweet pea is propagated by sowing, which can be carried out in spring and autumn, and it can be sown in autumn in North China from August to September. Seeds have hard grains, use 40 before sowing. C soaked seeds in warm water for one day and night, germinated neatly, and then planted in the greenhouse, or sowed directly in the greenhouse basin from September to October. 10~13cm with basin diameter, 3-5 tablets on demand. After emergence, leave a strong seedling, sweet pea is not resistant to transplantation, more direct seeding seedlings, or pot sowing seedlings, to grow into seedlings, off-pot transplantation to avoid root damage, the suitable temperature for germination is about 2OC.

Sweet pea seeds sprout:

Seed sprouting sweet pea is mainly propagated by sowing method, and germination is the first step of cultivation. At the beginning of the experiment, the common low temperature induction treatment of 5 ℃-10 ℃ and the method of constant temperature of 20 ℃ were used to accelerate germination, but it was difficult for seeds to germinate. In order to solve the problem of difficult seed germination, chemical treatment and germination experiments at different temperatures were carried out. The results showed that the effect of seed germination was the best in 15 ℃-25 ℃ incubator after sulfuric acid treatment. The early flowering can be achieved by low temperature treatment after budding and vernalization at low temperature. Sweet pea is a biennial overwintering plant, which goes through a period of low temperature during its growth period, and then blossoms in the spring of the following year, while low temperature treatment in the bud and seedling stage can make the plant pass vernalization ahead of time, make the flower bud differentiate smoothly and bloom ahead of time. The effect of low temperature treatment varies depending on the variety and the number of days of treatment.

Cultivation and maintenance of sweet pea:

Sweet pea pot soil is made of rotten leaf soil, peat, river sand and part of organic fertilizer, diluted liquid fertilizer is applied every 10 days before flowering, potassium dihydrogen phosphate is applied at the initial stage of flower bud formation, and watering is based on the principle of inter-dry and wet. The cultivation temperature should not be too high, before flowering, the daytime temperature is 9-13. C, 5-8C at night, the temperature is too high, the plant will bud before it is fully developed, which will affect the plant growth. When flowering, the room temperature increases to 15~2OC, which is beneficial to flower formation. Greenhouse or housing maintenance, the need to put potted flowers in front of the window to receive light, to pay attention to ventilation to prevent overgrowth or buds.

Cultivation and maintenance of passionflower

Passionflower, also known as egg fruit, is a perennial evergreen herbaceous vine of the genus Passiflora of Passiflora. Tendrils are axillary. Leaves alternate, 3-parted, base cuneate or cordate, margin serrate. Cymes reduced to a single flower, 7 cm in diameter, 5 sepals, abaxially green, inner white, 5 petals, white slightly purplish halo, corona composed of many twisted filaments, purplish red and white. The fruit is ovate and yellow when ripe.

The common cultivated varieties are:

"Flower fragrance", flower diameter 12 cm, purplish red, yellow heart, fragrant pea, eggplant-shaped fruit, sweet and slightly sour

"Adularia", the vine is 5 meters long, the flowers are small, pink to apricot yellow.

The species of the same genus are:

"winged passionflower", with a vine length of 4 to 5 meters, a flower diameter of 10 cm, a deep red flower, a purple-and-white Corolla, and edible fruit.

"Red banana passionflower", vine 5 meters long, flower diameter 12 cm, dark pink, fruit shaped like a banana

"Blue passionflower", with a vine length of 9 meters, a flower diameter of 10 cm, a white flower, a coronal blue, a small, orange fruit.

"Violet passionflower", with 7-8 meters long vines, 5-7-lobed leaves, white flowers, 7.5 cm flower diameter, purplish red flower heart and dark purple fruit.

"Big fruit passionflower", vine length 15 meters, leaf entire margin, flower diameter 12 cm, flower blue-purple, fragrant, fruit yellow, fruit as big as melon, weighing 3000 grams.

Passionflower is native to the southeastern United States and is cultivated in all provinces in the south of China. Like warm, moist and sunny environment. It is not cold-tolerant, but the American hybrid "Huaxiang (Incense)" can tolerate-30 ℃ low temperature in winter. Avoid waterlogging. In winter, the aboveground parts of Jiangsu and Zhejiang will wither and germinate in the following spring. Like loose, fertile and well-drained sandy loam.

Sowing and cutting propagation are commonly used. It can be sown in spring or autumn. Before sowing, the seeds should be pretreated with low temperature (0 ℃) for 3 months, the optimum temperature for germination was about 20 ℃, and germinated 30-180 days after sowing. It is suitable for cutting in May, cutting 10-12 cm twigs, cutting with heel, inserting into sand bed, cutting bed temperature controlled at 18-20 ℃, 25-30 days can take root.

If you can plant in tropical and subtropical areas, choose places with good drainage and plenty of sunshine. It can be cultivated or potted in summer in the north. Apply sufficient basic fertilizer before planting, the branches and vines grow rapidly, when the vine is 20 cm long, it is necessary to set up scaffolding, tie up the scaffolding, properly remove the weak branches on the side, and contribute to the stout of the main vine. During the growing period, fertilizer was applied once a month, and phosphorus and potassium fertilizer was applied twice during the flowering and fruiting stage. The stems gradually wither in winter, cut off the dead branches and cultivate the soil to survive the winter. In cold areas, potted plants can only be planted in greenhouse, and the room temperature should be kept above 10 ℃ in winter. Powdery mildew and aphids sometimes occur. Powdery mildew can be controlled by spraying 65% Dysen zinc wettable powder 500 times. The aphids were sprayed with 1500 times of omethoate EC.

Passionflower branches have slender vines, strange flower shapes, rich colors and fruitful fruits, which can be seen both in flowers and fruits, and the fruit is sweet and delicious. It is widely planted in small gardens in tropical and subtropical areas, allowing it to wind freely on flower walls or hedges to form a wild landscape. Two passionflower can be appreciated and eaten, so it can be said to be a good flower to kill two birds with one stone.
