Characteristics of primrose:
Primula, also known as the annual flower, primrose, four seasons spring, native to China. I like the warm, humid environment and well-drained, humus-rich soil. Not resistant to high temperatures and strong direct sunlight, most are not resistant to severe cold. It is a primrose family and a primrose. herb. Ye Jisheng, the whole plant is white fluff. Flowers usually of type 2, arranged in umbels or flower heads. Flowering from December to April. Primula is cultivated in the world and has a long history. It has developed rapidly in recent years and has become an important class of garden flowers. Zhongming Baochun and the scientific name Primula all contain the meaning of early flowers. Early spring flowering is an important characteristic of this genus.
Primula breeding method:
1. Soil: The potting soil should be 2 parts of humus soil and 1 part of garden soil, and a small amount of base fertilizer should be applied. This culture soil is loose and fertile, and is mostly slightly acidic to facilitate root development.
2, light: primrose sex light, but avoid strong sunlight, the summer seedlings should be placed in the shade of the wind and more visible scattered light. From September, the basin plants can receive more scattered light. From October onwards, the pots can be placed under full light, so that they can receive late autumn light to promote their growth and flower bud differentiation.
3, temperature: primrose is warm, slightly cold-resistant, suitable for growth temperature is about 15 °C, winter room temperature such as 10 ° C, can surpass winter above 0 °C, summer temperature can not exceed 30 ° C, afraid of strong light, so take cover Shade cooling measures.
4, watering: primrose likes a humid environment, but it is not appropriate to water too much, the basin soil is too wet, it will smash the roots. In the summer, if the watering is improper, the seedling plants will die, so in summer, you should pay attention to the amount of watering and the number of watering. Generally, water should be poured once a day in the morning and evening. When the weather is particularly dry around noon, spray water on the plants and the ground around the basin to increase the air humidity and lower the temperature, and create a cool and humid climate to facilitate its growth. The amount of watering and the number of watering should be appropriately reduced in the autumn. After entering the room in winter, pay attention to proper watering as the growth and buds bloom.
5. Fertilization: Apply 10 times of nitrogen-phosphorus combined with thin liquid fertilizer or compound fertilizer 10-10 days after slow seedling. After the autumn, the weather gradually cools down, and the spring season gradually enters into a prosperous growth period. At this time, the management of fertilizer and water should be strengthened. Each time the submerged thin pancake liquid is applied once every 7-10 days, the nitrogen fertilizer should be applied in the early stage to promote the fertilization of the branches and leaves; In the later stage, the composition of the phosphate fertilizer should be appropriately increased, and 0.3% potassium dihydrogen phosphate aqueous solution should be sprayed into the leaf surface every half month to promote the flowering of the multiple buds until the bud.
6, insect pests: primrose seedlings are weak, prone to stagnation disease, causing seedlings to rot and die, should pay attention to timely spraying and prevention. If the disease has occurred, a small amount of 70% dikesone powder can be mixed with 40 times of fine sand into the potting soil, or 800 times of liquid sprayed on the soil surface, which has good control effect.
7. Pruning: During the flowering period, select the plant that has just seeded, remove a part of the flowering branch, and add 1-2 times of thin fertilizer with phosphorus fertilizer as the main to make the seed full and full. After the flower is thanked, it should be cut off in time, and 1-2 times of thin fertilizer should be applied to facilitate the growth of new flowering branches, and then it can continue to bloom.
Primula is a kind of flower plant that is open in early spring. The colorful flowers such as red, pink, yellow, white and purple are very beautiful. The low-potted small potted plants are delicate and cute. They are used to decorate the flowers commonly used in homes. First, the breeding method of primrose is introduced to everyone here, I hope to help everyone.
