Let's introduce the advantages of using soilless cultivation equipment:

(1) Effectively prevent soil continuous cropping obstacles and soil-borne diseases.

Since the environment of soilless planting is completely isolated from the soil, it can effectively prevent the occurrence of soil-borne diseases. As long as the seeds, culture medium, equipment, nutrient solution, etc. are carefully disinfected and managed properly, it is generally not easy to be infected with diseases, and a high degree of continuous cropping can be implemented, which greatly improves the land utilization rate. It is precisely because the soilless planting method has irreplaceable advantages in preventing the occurrence of soil-borne diseases.

(2) Improve the yield and quality of crops.

The use of soilless planting technology can artificially control the environmental conditions such as temperature, light, water, nutrients and other elements required by crops. Therefore, compared with conventionally produced vegetables, the yield is higher, the quality is better, the products are clean and hygienic, and the economic benefits are good. Since the balcony soilless planting does not use organic fertilizers, the contamination of the products by the parasites of the organic fertilizers in the soil can be avoided, and diseases rarely occur. Therefore, pesticides are rarely applied, which solves the problem of pesticide residues in vegetable products to a certain extent.

(3) Save water, fertilizer and labor.

In the cultivation process, management links such as seedling raising and soil preparation, soil ploughing, watering, cultivating weeding, and pest control can be omitted, which can save a lot of labor. In the balcony soilless planting site with a certain scale, mechanized operation and automatic management can also be implemented. The nutrient solution in soilless planting can be formulated and adjusted according to the nutritional needs of different crops in each growth period. Water waste due to evaporation and loss. Therefore, water and fertilizer saving can be achieved.

(4) Not limited by natural conditions.

The planting site of the soilless planting device is not limited by soil quality and water conservancy conditions, especially in areas with harsh conditions such as deserts, barren land, and drought. It is an effective method of crop cultivation.

Introduce the method that utilizes soilless cultivation device of the present invention to carry out interplanting sunflower and garlic below:

(1) Sowing time: Sunflower is sown in May-June, and garlic is sown in August-September.

(2) Planting area: The sunflower-centered planting method is adopted, sunflowers are planted in the planting holes of the upper cultivation board, and garlic is planted in the planting holes of the lower cultivation board.

(3) Harvest

Sunflower blooms in August-September, and seeds mature in October-November. Garlic planting on the balcony is generally based on harvesting green leaves. When the seedlings grow to 20cm, they are cut off at a distance of 3-5cm from the cultivation board and continue to manage. Harvest 2-3 crops in a row.

Benefit analysis of the soilless cultivation device of the present invention:

Soilless culture provides a coordinated supply of water, air and fertilizer for the root system, and has a good buffering capacity, enabling the cultivated plants to grow healthily and quickly, and has the characteristics of improving the quality of cultivation, so it can save fertilizer and water, and reduce costs. The sunflower is calculated on a per mu basis at 33 yuan per mu for seeds, 200 yuan for fertilizer substrate, 166 catties per mu, 10 yuan per catty, and net income of 1427 yuan per mu after deducting the input. Sunflowers have a short growing season, only 90 days from sowing to harvesting. The applied fertilizer nutrients cannot be fully absorbed, and can be absorbed and utilized by the next crop, thus solving the contradiction between less land and high income, and it is necessary to use less land. To create high efficiency, adopting this hybrid planting method is equivalent to harvesting two crops on the same land.

It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any relationship between these entities or operations. any such actual relationship or sequence exists.
