Soilless culture 

Introduction 

Substrate cultivation is a kind of soilless cultivation that has the biggest promotion area.It fixes the crops roots in organic or inorganic matrix,supply nutrient for crop through drip or trickle irrigation .Cultivation matrix can be loaded into plastic bag, or laid in cultivation groove or trough.Nutrient solution of substrate cultivation is not cycle,which can avoid disease spread through the cycle of nutrient solution.

Substrate cultivation has strong buffer ability, and there is no contradiction between moisture, nutrients, and oxygen supply.In addition, substrate cultivation has easy equipment, sometimes does not need any power, therefore, it is less investment, low cost, common application.

Hydroponics cultivation refers to plant roots directly in the nutrient solution without substrate cultivation.The most famous and common hydroponics is Nutrient Film Technique (NFT),its working principle:make a very thin layer of nutrient solution (0.5-1.0cm) cycle through the crop root, not only ensure continuous water and nutrient supply for crop, but also fresh oxygen supply for the root.Nft cultivation method greatly simplifies the irrigation technology, need not calculate crop water requirements everyday, and can ensure balanced nutrients supply.NFT cultivation method takes part roots from the soil, avoiding all sorts of soil borne disease, also no need for soil disinfection.

Dutch soilless cultivation 

1. Can achieve early crop maturity and improve crop yield.

2. not use farm manure, and there are few pests and diseases, and no large amount of pesticides, the products produced are safe, clean and pollution-free.

3. Has the advantage of saving time and labor, because there is no need for soil cultivation, weeding and fertilization and other links, the workload of field management is greatly reduced.Nutrient supply is also automatically controlled, improving working conditions and reducing labor intensity.

4. Can save more than 50% water and fertilizer compared with traditional soil cultivation.It can avoid the phenomenon of serious soil-borne diseases, soil salinization and soil acidification caused by frequent continuous cropping

5. The Dutch model of soilless cultivation makes full use of land and space

Dutch barrels 

Dutch barrel with siphon loading substrate, can be used in substrate culture (with non-woven bag of perite and nutrient solution dropper, below the barrel can be connected with PVC pipe, for collecting liquid, can also be used in aeroponics, fish and vegetable symbiosis and other systems.

PVC growing groove cultivation system 

Growing groove is PVC material, inside is set drainage ditch, thickness 4mm, end cap, connection,drainage pipe.

Hot galvanized supporter.

PVC growing groove cultivation system

Strawberry seedling three-dimensional planting tank, soilless strawberry cultivation tank, it uses the support of the strawberry tank, put the isolation film and substrate, the substrate can choose loose coconut bran or coconut bran bag, the bottom is supported by the guide plate, the upper laying drip irrigation belt for irrigation.

Growing bag

Growing bag is black and white PE plastic ,10 micron thickness.

Advantages of planting bags:

1. Speed up rooting

2. Improved survival rate of transplantation

3. Save packaging and transportation costs

4. A wide range of applications

5. Convenient transplantation

6. It can be repeated

7. low cost.

NFT hydroponics system NFT 

Automatic circulation management, through the timing device to control the water circulation, increase the supply of nutrients in the water, and when the nutrient solution evenly absorbed, from the planting of vegetable seedlings, basically without manual management.Harvested vegetables nutrition and health, basically do not produce pests, do not use pesticides, and can be picked with eating, to maintain the freshness of vegetables.

From the family adornment for, also won’t affect the beautiful of domestic balcony, it is a special scenery instead.

Pipe hydroponics also has a major feature, the style can change multi-terminal, italic, tiling, multi-layer, column, double-sided, wall, size can also be freely designed, according to the area of the family balcony to adjust the size of the pipeline system.The most suitable leaf vegetables for hydroponics are lettuce, chicory, Chinese kale, cabbage heart, moss, large leaf mustard,collard greens, purple sunflower, watercress, water cress, three-leaf celery, amaranth, etc.Vegetables suitable for hydroponics mainly roots can adapt to the water environment, basically are developed hair roots.
