Herbal flower flower seaweed cultivation techniques

Herbal flower flower seaweed cultivation techniques

1. Selection of flower sea herbs

(1) One-two-year-old herbaceous flowers: Under local cultivation conditions, the herbaceous ornamental plants that can complete the whole growth and development process after sowing are called annual flowers; the herbaceous ornamental plants that complete the whole growth and development process after the autumn sowing are called biennial flowers. Due to the different climates and cultivation conditions, there is often no obvious boundary between them. Gardening often refers to the two as one or two-year-old flowers, or simply grass flowers. Some perennial flowers that are cultivated for one or two years of flowering are sometimes included. The one-and-two-year-old herbaceous flowers have many characteristics, such as bright colors, simple cultivation, concentrated flowering, adjustable flowering period and short growth cycle. They are the main types of application in the flower sea landscape. The main varieties are cosmos, sulphur chrysanthemum, zinnia, sunflower, cleoptera, corn poppy, flower weed, rape, marigold, and yuelan.

(2) Perennial herbaceous flowers: refers to herbaceous plants that have an individual life span of more than 2 years and can bloom many times. It has the characteristics of large flower color, long flowering period, strong plant adaptability and pruning resistance. Because it is planted in a suitable environment, many species can self-reproduce by sub-balls or perennial roots, eventually forming natural color blocks, which do not need to be replaced frequently, and the application in flower seas is gradually increasing. The main varieties are verbena verbena, phlox, lavender, sage, rudbeckia, evening primrose, purple Echinacea, and celandine.

2. The form of the flower sea landscape

(1) Single species planting: Planting a variety of herbaceous flowers in a large area or in a unit planting area. It can form a landscape effect in a short period of time, the flowering is neat and uniform, the flowering effect is very shocking, and it can attract tourists to a large extent. It is the most commonly used form of flower sea landscape. However, the herbaceous flower plants are more delicate and prone to lodging, and the landscape effect is not sustainable, which is easy to cause aesthetic monotony and fatigue. Therefore, when planting a single variety, it is necessary to consider the color and shape of the plant and the surrounding environment, or to add appropriate garden pieces and buildings for configuration. The planting design can be carried out in blocks or ribbons.

(2) Multi-species combination planting: According to the growth characteristics, plant height and color system of the herbaceous flowers, the wild herbaceous plant community is simulated to rationally arrange more than three kinds of herbaceous plants for planting in a large area. It can achieve the advantages of wide color range, strong layering effect, good viewing effect, and long flowering period in spring, summer and autumn. Through the self-propagation and reproduction of herbaceous flowers, the landscape effect can last for two or three years, which is the trend of the recent development of the herbaceous landscape of the herbaceous plants. The shortcoming of this form of construction is that the cultivation period of the flower sea is long, and it takes a relatively long time to achieve the best viewing effect. When planting, choose the appropriate herbal and floral combination according to the type of climate at different locations and the desired landscape effect.

Whether it is a single variety planting or a combination of multiple varieties, it is necessary to follow the principle of “suitable for flowering” and pay attention to the careful matching of flowering, color and season. According to the ecological habits of herbaceous flowers and planting environment conditions, rationally planting, taking into account the sustainability of landscape and ecology, creating a colorful four-season landscape effect.

3, herbal flowers, flowers, seaweed cultivation

The herbaceous flowers and flowers are mostly cultivated in the open field. The cost of the herbal flowers used in the open field cultivation of flowers and seas is 1~3 yuan/m2, and the seeding amount is generally 2~5g/m2. Compared with container cultivation and facility cultivation, open field cultivation is cheaper, simple to manage, and has a good background effect.

3.1 Pre-planting work

(1) Planting soil: The herbaceous flowers cultivated in the open field have strong adaptability, and the general soil conditions are suitable for their normal growth. Preparations to be done: 1 Try to clean up the weeds and debris in the soil. 2 Improve soil structure. For the improvement of sandy soil and excessively viscous soil, the application of organic fertilizer and phosphate fertilizer will be applied to the long-term plantation of flower seas and soils with low organic matter. 3 to turn over the ground. It usually takes two or three rounds of operation, and the depth is in the 30~50cm soil layer. When the ground is turned over, it can be combined with soil improvement.

(2) Seeding methods: divided into spreading, stripping, and on-demand. The planting method is determined according to the size of the Huahai block, the terrain and the size of the seed. Most herbaceous flowers can be grown by direct spreading. Areas with a slope greater than 45, difficult watering, and too strong sand can be planted by planting ditch and on-demand.

(3) Planting time: The natural sowing time of herbaceous flowers mainly includes spring and summer sowing (3~8 months) and autumn sowing (9~11 months). Spring and summer sowing summer and autumn type flowers, after sowing, after 45~90d growth, flowering, flowering period of 40~50d. Such varieties as cosmos, sulphur chrysanthemum, sunflower, zinnia, etc., can be used as spring flowers in the spring to create a “five-node” landscape, and planting from June to July can be used to create an “eleven node”. Flower sea landscape. The autumn sowing spring flower type enters dormancy under low temperature conditions after sowing in about 1~2 months after sowing. After the spring temperature rises, the flowering stems bloom, and the flowering period is from March to May. The varieties are like 虞美人,福禄考,二Yuelan, etc., as a spring landscape.

(4) Covering watering: After sowing, gently cover the soil to ensure that most of the seeds and soil are in full contact. If large-area sowing is to be covered with a non-woven fabric, it will act as a moisturizer to prevent rainwater from scouring. Herbal flower germination and seedling stage need sufficient water, watering after covering, to ensure that 10cm soil layer is moist, the emergence rate is about 60~70%, then remove the non-woven fabric in time, and continue to moisturize for about 20d, in order to facilitate the seedling Growing.

3.2 Late custody work

(1) Fertilization: Appropriate top dressing is beneficial to the growth and flowering effect of herbaceous flowers. According to the growth of plants, compound fertilizer can be applied 2~3 times before the flowering stage to before flowering.

(2) Weeds: Weeds should be strictly controlled in the growth period of herbaceous flowers. Timely weeding work is conducive to the growth of seedlings.

(3) Pests and diseases: prevention is the main, prevention and treatment are combined. Focus on prevention work before seedling and flowering, spray carbendazim, methyl thiophanate and imidacloprid.

(4) Pruning: After the full flowering period, the pruning of the residual flower leaves is carried out to maintain a good landscape effect. If it is possible to self-sow and multiply, the last part of the water is cut before the winter, and the ground part is cut.

4. Construction of Huahai landscape culture

As the process of urbanization continues to accelerate and the material living standards continue to improve, people's lifestyles and leisure methods are slowly changing. The pursuit of beauty is not limited to a comfortable living environment, but a more attention to physical and mental experience. The sea landscape is not only satisfied with simple sightseeing and photo-taking. There are many creative practices in the country for the flower-sea landscape, but most of them are duplicates, lack of features, single content, and insufficient cultural development, which makes the development of the flower sea landscape face. A variety of issues. For the people's needs, the construction of the sea landscape will also expand towards the complex, enhance the interaction between people and the landscape, let the cultural connotation of the flowers show up, let people participate in it, make the flower sea landscape have economic functions, leisure functions, Multi-level composite functions such as popular science function and ecological function. For example, flower science and sightseeing, taking the knowledge of popular science flowers as the leading factor, carrying out flower cultivation, floral design, flower creation and other activities to enrich people's experience; Huaxiang ecological holiday, creating a beautiful holiday environment with flowers and sea, combined with local agricultural production Folk culture provides people with a natural and simple experience; the Flower Industry Expo visualizes the entire chain process of flower production, allowing people to experience the entire industry's operating model in a deeper level.
