In order to make full use of the high-yielding characteristics of soilless cultivation technology and increase the production per unit area, it is necessary to choose high-quality, high-yield, and disease-resistant varieties. When managing soilless cultivation, it is necessary to make plans in advance. Do not change the amount of liquid supplied in the cultivation bed at will. It is required to have a liquid supply of more than 5 liters per minute. In addition, because soilless cultivation

Soilless cultivation means that natural soil is not used, and due to some specific Environmental conditions, cultivation methods, and the inconsistent and rational use of chemical fertilizers and pesticides have caused great changes in soil composition. A series of problems such as land salinization and continuous cropping obstacles have become increasingly serious when cultivating plants, which have greatly restricted the development of facility agriculture.

Conditions for soilless planting

There are three conditions for soilless planting. One is to provide comprehensive and sufficient nutrients for the plants, the other is to fix the plants, and the third is to provide water and Make sure there is a certain concentration of air in the water, and of course there must be sunlight and appropriate temperature.

How to cultivate without soil

1. Variety selection:

Cultivation of high-quality varieties is mainly to make full use of the high-yielding characteristics of soilless cultivation technology. , to increase the production per unit area, so it is necessary to choose high-quality, high-yielding, disease-resistant varieties.

2. Reasonable and dense planting:

Soilless cultivation technology should achieve ventilation and light transmission, reasonable and dense planting, increase unit production, and improve planting effect. When planting, you should choose healthy and vigorous plants. , vegetable seedlings that are uniform in size, moderate in plant spacing, and maintain corresponding density in row spacing, and other vegetable types can be used according to actual conditions to make flexible use of limited space to increase planting volume and production per unit area.

3. Reasonable irrigation:

After cultivation, water should be watered in a timely manner to speed up the normal growth of cultivated plants. According to the different growth and development stages of the cultivated plants, more frequent watering is needed. , Therefore, it is necessary to irrigate properly to ensure the normal growth of plants.

Soilless management technology

When managing soilless cultivation, the amount of liquid supply in the cultivation bed must be determined in advance and should not be changed at will. It is required to have a supply of more than 5 liters per minute. In addition, because the plants in soilless cultivation grow vigorously, it is necessary to reshape the plants and clean old leaves, and maintain ventilation and light transmission.
