Primroses

Primula is a perennial herbaceous flower of Primulaceae. The leaves are basal, forming rosette-shaped foliage, with long oval-shaped leaves, drooping edges, irregular circular serrated leaves and tomentose back leaves. The flower or scape is drawn from the plant base to form a single flower or a sequential flower from the scape, with 5-7 petals, with red, white, yellow, purple, pink, orange, peach, rose, complex color, discoloration and other colors, very gorgeous and pleasing to the eye. The flowers bloom from December to May of the following year, with high ornamental value.

According to the author's practice of cultivating spring for many years, attention should be paid to the following maintenance and management work:

Early sowing and early transplanting seedlings should be sown from May to June, transplant when the seedlings grow to 2 or 3 leaves, and move the seedlings again when they reach 4 true leaves. Humus soil is the best soil for transplanting. Because it is hot summer at this time, the temperature is high, so the seedlings should pay attention to shading, cooling, can spray 50% carbendazim 500 times 800 times a week, and spray more on the basin soil to prevent stem rot. After twice transplanting, the root system is strong and developed, and the plant is short and strong, which can be planted in pot from September to October.

After the application of fertilizer frequently, the weather is gradually cool after autumn, and the spring report gradually enters the vigorous growth period. at this time, the management of fertilizer and water should be strengthened, and the mature thin pancake fertilizer should be applied every 7 to 10 days, and more nitrogen fertilizer should be applied in the early stage to make the branches and leaves fat. at the same time, the composition of phosphate fertilizer should be increased appropriately, and 0.3% potassium dihydrogen phosphate solution should be sprayed to the leaves every half a month to promote its multiple pregnant buds to bloom until budding.

Properly water the spring and like the humid environment, but it is not suitable to water too much, the basin soil is too wet, it will rot the roots. Improper watering in summer will kill the seedlings, so we should pay attention to the amount of water and times of watering in summer. Generally speaking, water should be watered once in the morning and evening every day. When the weather is especially dry and hot around noon, water should be sprayed to the ground around the plant and basin to increase air humidity and lower the temperature, creating a cool and humid climate environment to facilitate its growth. The amount of water and times of watering should be reduced appropriately when it is cool in autumn. After entering the house in winter, you should also pay attention to proper watering as you grow and blossom.

The light is suitable for spring, but avoid strong sunlight. In summer, pot plants should be placed in a cool and ventilated place where scattered light is common. From September, the pot plant can receive more scattered light, and from October, the pot plant can be placed in full light to receive more late autumn light to promote its growth and flower bud differentiation.

Picking flowers and arrows to promote more tillers and report spring is generally appropriate to move into the indoor warm and common light in mid-late October, when the temperature is suitable, and the seedlings grow rapidly. when the plant grows to 10 leaves, there are flower arrows, which can bear more than a dozen flowers, which requires a lot of nutrients. In order to make the plant more tillering, multi-bud blossom, can be removed when you see the first flower arrow, to benefit more tillering, expand the plant, so that before and after the Spring Festival Each pot can give birth to more than 5 flower arrows, flowers full of pots, cymose inflorescences live in groups above the green leaves, gorgeous and colorful, very enduring.

Properly control the temperature and report the spring is slightly cold-resistant, do not like high temperature. The room temperature should be kept at 15: 20 ℃ in winter and 8: 10 ℃ at night. When the spring blossoms in December, the room temperature can be controlled at about 5 ℃, which can prolong the flowering period and add color to the festival.

The common diseases of controlling diseases and insect pests are leaf spot and stem rot. The former can be sprayed with 2000 times of 50% zinc solution once every 10 days, while the latter sprays 80% wettable zinc solution every month and pulls out the diseased plant in time. If you are harmed by red spiders, you can spray 1200 times of dicofol, and pay attention to ventilation at the same time. How to raise melon and leaf chrysanthemum

Perennial herbs of Chrysanthemum morifolium. The leaves are dirty, similar to melon leaves; the colors of flowers are usually red, light red, white, pink and rose, as well as colors from sky blue to dark blue, and complex colors such as white, purple, red, white and so on. Petals are wide, narrow, flat, curly and single, double and so on. The florescence is very long.

Melon leaf chrysanthemum likes to be warm, moist and avoid hot and dry. Afraid of bright light and frost. Sandy loam with rich humus, loose and fertile soil and good drainage is required. In order to make melon, leaf and chrysanthemum blossom, pay attention to the following aspects:

1. The basin soil can be cultivated with rotten leaf soil, garden soil and sandy soil mixed with a small amount of cake fertilizer.

2. When the plant has 5-6 leaves, the terminal buds will be removed to promote the lateral buds to germinate, and each plant will retain 3-5 lateral buds to make them grow into flower branches, which can make the plant shape full and the leaves luxuriant. Lateral buds germinated from the base of the plant during growth should be erased at any time to concentrate nutrients.

3. Because of its large leaf area and high water demand, melon and leaf chrysanthemum need to be watered frequently to keep the basin soil moist to prevent wilting.

4. it takes a long time to bloom and consumes a lot of nutrients, so fertilizers need to be replenished in time in the process of growth. The times of fertilization should be determined according to the actual growth situation. If the plant grows slowly and the leaf color is light and thin, the second thin fertilizer can be applied every 10 to 14 days. If the leaves are stretched and the color is dark green, the times of fertilization can be reduced as appropriate. Nitrogen fertilizer was the main fertilizer at seedling stage, and liquid fertilizer combined with nitrogen and phosphorus was applied after winter to promote flower bud differentiation.

5. Melon-leaf chrysanthemum is a light-loving plant. During the growth period, it can only be cultivated in the sunny place with dark green leaves and bright flowers; it is afraid of strong light and high temperature, if it is exposed to strong light, it is easy to cause dry curvature of leaves; if it is exposed to high temperature, it is easy to cause stems and leaves to grow and affect flowering.

6. Proper shading should be paid attention to after summer. In the middle of summer, move the flowerpot to a cool place with the same wind to avoid the hot sun. At the same time, adequate watering in summer, but also need to often spray water on the plant and wine on the ground around the flowerpot to cool down and humidify. This is beneficial to the growth of leaves and makes them tall and straight.
