How to grow soilless rice?

First, the advantages of soilless culture

1, saving water, fertilizer and high yield

In soilless culture, all kinds of nutrient elements needed by crops are artificially prepared into nutrient solution for application, which has less water loss, balanced nutrient components and high absorption efficiency, and provides nutrients scientifically according to crop types and different growth stages of the same crop. Therefore, the crops are robust and have strong growth potential, which can give full play to the potential of increasing production.

2, clean and pollution-free

The application of organic fertilizer in soil cultivation and the decomposition and fermentation of chemical fertilizer will produce odor, pollute the environment, breed eggs of many pests and endanger crops. However, the application of inorganic fertilizer in soilless culture does not have these problems, which can avoid the pollution of harmful substances such as heavy metals in polluted soil.

3, labor-saving and easy to manage

Soilless culture does not need intertillage, digging, weeding and other operations, which saves labor and effort. Watering and topdressing can be solved at the same time, and the liquid supply system can supply it regularly and quantitatively, which is convenient for management, will not cause waste and greatly reduce the labor intensity.

4. Avoid continuous cropping obstacles

In the field planting management of vegetables, reasonable land rotation and avoiding continuous cropping are one of the important measures to prevent the serious occurrence and spread of diseases. Soilless culture, especially hydroponics, can fundamentally solve this problem.

5. Make full use of space, regardless of geographical restrictions.

Soilless culture completely isolates crops from soil environment and is not limited by soil quality and water conservancy conditions. Many deserts, wasteland or areas difficult to cultivate on the earth can be utilized by soilless culture. Without the bondage of land, soilless culture can also be free from space restrictions. Using the flat roofs of abandoned factories and buildings in cities to grow vegetables and flowers has virtually expanded the planting area.

6, is conducive to the realization of agricultural modernization.

Soilless culture makes agricultural production get rid of the restriction of natural environment and can be produced according to people's will, so it is a controlled agricultural production mode. Farming according to quantitative indicators is conducive to mechanization and automation to a greater extent, thus gradually moving towards industrialized production methods.

Advantages of soilless culture of flowers;

(1) grows fast and has good quality. Because the nutrient solution used in soilless culture is carefully prepared according to the needs of flower growth and development, which is conducive to the rapid growth of flowers, there are many flowers, large flowers, bright colors, long flowering period, strong fragrance and lasting green leaves.

(2) Clean and sanitary, with few pests and diseases. Planting flowers with soil and applying organic fertilizer will inevitably pollute the environment and easily cause diseases and pests. The fertilizer for soilless culture is a nutrient solution made of inorganic elements, and the substrate is disinfected, clean and hygienic, which can greatly reduce the harm of pests and diseases.

(3) Save fertilizer and water. Soilless culture has a fixed container, and there is little loss of fertilizer and water.

(4) Low labor intensity, saving labor and time. Soilless cultivation of flowers does not need to carry heavy flowerpots, and the containers used are mainly plastic, and the substrates used such as vermiculite and perlite are very light. In management, it is only necessary to supplement the nutrient solution prepared in advance regularly and constantly replenish water, which is simple and convenient to operate and saves labor and time.
