Study on the Development of soilless cultivation techniques of Flowers

I. characteristics of soilless cultivation of flowers

(1) the flowers cultivated in soilless culture have fast growth rate, high yield and good flower quality.

Soilless cultivation of flowers is different from ordinary flower vegetation, soilless cultivation of flowers has many advantages. Take the soilless cultivation of carnation, for example, the growth period of carnation is short, the florescence is long, there are many flowers, and the fragrance is strong. The phenological phase of impatiens cultivated in soilless culture is 3 to 14 days earlier than that in soilless culture, and the flowering time can be prolonged by 7 to 12 days. At the same time, the biomass of impatiens cultivated in soilless culture is increased by 33% to 74.5%. This is enough to prove that soilless flowers are much better than ordinary flowers.

(2) soilless cultivation can save a lot of fertilizer, water resources and labor.

Soilless cultivation of flowers and plants is to prepare nutrient solution according to the amount of nutrition needed by flowers, thus effectively simplifying the technical links of soil preparation and ploughing in soil cultivation, at the same time, soilless cultivation of thinking flowers is conducive to the implementation of automatic operation, the use of a large number of modern equipment, effectively reduce manpower and material resources, but also improve labor efficiency, thus saving fertilizer and water resources.

(3) soilless cultivation is conducive to environmental protection and sanitary protection, and can effectively reduce the occurrence of diseases and insect pests.

As soilless cultivation is basically carried out in a soilless environment, it plays an important role in environmental protection. At the same time, because soilless cultivation is basically completed indoors, such a growth environment is conducive to reduce the incidence of plant diseases and insect pests, and then improve the quality and yield of flowers. Therefore, soilless cultivation is conducive to environmental protection and health protection, can effectively reduce the occurrence of diseases and insect pests, and then effectively improve the product quality and brand efficiency of flowers.

Second, the present situation of the development of soilless cultivation techniques of flowers.

From the perspective of the whole international environment, the technical research of soilless cultivation in China started late. However, in recent decades, most of the soilless cultivation techniques in China use advanced energy-saving greenhouses. The adoption of this technology has effectively promoted the rapid development of Chinese facility horticulture and landscape construction industry, and also promoted the development of soilless cultivation. The continuous renewal of soilless cultivation techniques of flowers is the main condition to ensure the development of soilless cultivation of flowers. In recent years, great changes have taken place in the techniques of soilless cultivation of flowers in China, which are mainly as follows:

(1) the technology of soilless cultivation in China is constantly updated and the facility system is constantly improved.

From the overall point of view of our country, although the soilless planting technology in China started relatively late, the speed of development is very fast, especially in recent years. Generally speaking, with the continuous renewal and progress of soilless cultivation technology in China, the relevant research achievements of the Chinese Academy of Agricultural Sciences have made worldwide achievements. This fully illustrates the intensity of research and investment in soilless cultivation in China. At the same time, the supporting facilities related to soilless cultivation in China are constantly improving and improving, so as to better adapt to the development of soilless cultivation technology in China.

(2) the technology of off-season soilless cultivation in China has made rapid progress and the technical level is high.

In essence, the development ability of soilless cultivation depends on the competitiveness of terrestrial agriculture. Therefore, in the future agricultural development, we should not only improve the actual yield of soilless cultivation of flowers and plants, but also pay more attention to the high added value and industrial chain of soilless cultivation of flowers and plants, so as to improve the economic benefits of soilless cultivation. At the same time, in the process of soilless cultivation, more attention should be paid to the study of substrate to provide a strong theoretical basis for soilless cultivation.

(3) gratifying progress has been made in the research on the formulation of low-cost and high-benefit nutrient solution for soilless cultivation of flowers.

In modern flower soilless cultivation, the fertilizers currently used in China are basically valuable fertilizers with independent intellectual property rights in China. This kind of fertilizer not only has the function of disinfection and nutrition, but also has one of the characteristics of this fertilizer because of its low cost. On this basis, the Chinese Academy of Agricultural Sciences and related research institutes are still constantly studying new liquid fertilizers, and gratifying progress has been made in the research on the formulation of high-benefit nutrient solution, which greatly solves the problem of low survival rate and great loss of precious flowers. At the same time, the seed area of flowers has been expanded to a great extent.

Third, the development prospect of soilless cultivation of flowers.

The soilless cultivation technology of flowers, instead of the traditional flower planting technology, can effectively solve the contradiction of water, air and nutrient supply which is difficult to be solved in traditional soil cultivation, and make the crop root system in the most suitable environmental conditions. thus give full play to the potential of crop production. At the same time, soilless cultivation of flowers can effectively avoid soil-borne diseases, reduce soil pollution, and improve the product quality of flowers. In addition, non-map planting is the main trend of agricultural development in the future, new planting technology will greatly reduce the negative results brought by traditional planting technology, and then achieve twice the result with half the effort. From the perspective of the development of soilless cultivation technology of flowers in the whole world, the development of soilless cultivation technology of flowers has reached a critical stage. At the same time, the soilless cultivation technology of flowers is becoming more and more perfect, and the technology is constantly updated. Facts have proved that the higher the degree of simplification, modernization and automation of soilless cultivation of flowers, the greater the economic benefits of flowers. Although the soilless cultivation technology of flowers in China started relatively late, the technical level of soilless cultivation of flowers is currently at a low level. However, with the continuous updating and progress of China's economy, science and technology, China's flower soilless cultivation technology will become more and more mature, and its market will become bigger and bigger. The rise of soilless cultivation technology of flowers makes the development of horticulture and flower industry in the city into a new development stage, so the soilless cultivation technology of flowers has a very broad development prospect.

IV. Concluding remarks

China's flower soilless cultivation technology from scratch, from have to new, is the result of the continuous development of Chinese science and technology. The soilless cultivation technology of flowers is the main development trend of the whole economy in the future. Throughout the development of China, with the continuous development and improvement of China's economy, more and more people require to live in a clean, tidy, green and comfortable environment, so people will have higher and higher requirements for the environment. This is the higher requirements for the soilless cultivation technology of flowers in China. From the perspective of the trend of economic development in the future, the prospect of soilless cultivation of flowers in China is very good. With the deepening of the research on soilless cultivation technology, soilless cultivation technology will show broader development prospects in our country.
