Introduction of New varieties of Flowers in Spring

With the advent of spring, there are many new varieties on the market, and some of them have been published in this issue to provide dinner for readers.

Black-hearted Golden Chrysanthemum 'Denver Daisy'

Variety introduction: early flowering, long florescence, flowering from late spring to the first frost, wide adaptability, strong heat resistance and drought resistance, simple cultivation management and short cultivation time. Whether as a large area planting plant, container plant or as a flower border plant, its performance is very perfect. There are very large and abundant flowers.

Cultivation techniques: the culture medium is irrigated with fungicides to prevent lodging disease. Gently cover the seeds and maintain a balanced humidity. From 5 to 6 weeks after sowing, 1 to 3 seedlings were transplanted into 10-17 cm flowerpots or 3-5 liter containers. When plants can be transplanted to open spaces or flower sheds, use loose humus, 20% to 30% clay, 1.0 to 1.5 kg compound fertilizer per cubic meter, as well as iron chelates, trace elements, ph between 5.8 and 6.2, and keep the garden floor moist. The temperature is maintained at 18 °C to 20 °C, and the ventilation temperature is 22 °C. Use a compound fertilizer with a concentration of 150 to 200 grams of ammonia per liter per week, which is mainly composed of nitrate. Using iron chelates 1 to 2 times can prevent magnesium deficiency symptoms (leaves are small and yellowish white), and cathartic salt (0.05%) 1 to 2 times can prevent magnesium deficiency symptoms. Be careful not to be washed away in the open air. The minimum requirement for nitrogen is about 130 grams of ammonia per square meter. Pay attention to maintaining adequate trace elements. Key points of maintenance of succulent flowers in spring

Spring is coming, the earth warms up, everything recovers, and the juicy flower tree ushered in a new round of growth. It is of great significance to do a good job in the maintenance of multi-pulp flowers in spring.

Due to the vast territory and complex topography of our country, the climate varies greatly in different places, which forms the characteristics of complex and diverse climate types. In view of this, we should correctly judge the coming time of spring: geographically, spring is from April to May in North China and from March to April in East China. In terms of solar terms, the Beginning of Spring and Grain Rain all belong to spring. In addition, we can also say that spring is when the highest temperature reaches or exceeds 10 degrees Celsius for five consecutive days. Cultivation techniques of Pulp Flowers

When many people see that spring is coming and the plants wake up, they begin to maintain them normally. In fact, just after winter, the temperature difference between morning and evening is very large, and sometimes the temperature at night will be lower than 0 degrees Celsius, so it is still key to do a good job of anti-freezing. It is best not to ventilate for a long time, let alone put the plant in the air convection. I have visited some large enterprises that produce succulent plants. In spring, the planting trough in their greenhouse is often covered with a layer of plastic film, which is opened only at noon. The plants cultivated in this way are full of individuals and bright colors. For small and medium-sized enterprises, as long as the night temperature is not lower than 5 degrees Celsius, most varieties can be safe and sound. The cultivation place with heating conditions couldn't be better. If you don't have heating conditions, you can do a good job of keeping warm before the temperature drops suddenly.

Generally speaking, epiphytic species such as epiphyte, such as epiphyllum, are more vulnerable to spring freezing. For most apricot plants, such as fleshy cones, stone flowers and some "winter" species of crassulaceae, it is best to keep the temperature above 7 degrees Celsius. With the rise of the temperature, the light time will increase significantly, and most pulpy flowers can not lose light during this period, especially the varieties that bloom in spring. However, some varieties are very sensitive to light. For example, plants of the genus Scutellaria do not need strong light for a long time. In terms of water supply, the amount of water should be gradually increased with the increase of temperature, and it is best not to pour it directly on the plant, especially for some fluffy varieties. To put it simply, those who have not entered the growing period should be watered as appropriate, and those who do not enter the growing period should maintain sufficient moisture. In the link of fertilization, the topdressing in spring is mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer, and thin fertilizer is applied frequently. It is best to wait until the temperature is stable before applying fertilizer to the lower reaches of the Yangtze River around April (that is, around Qingming Festival and Grain Rain), you can often get immediate results.
