What are the common soilless cultivation modes of vegetables?
1. Coconut bran soilless cultivation
Coconut husk soilless cultivation is a soilless vegetable cultivation model using coconut husk as a substrate. The soilless cultivation device is equipped with drip irrigation system to save water and fertilizer. Coconut husk is a kind of natural organic medium, which is shed from the process of coconut husk fiber processing. It has good water retention, strong air permeability and can be reused.
2. Rock wool cultivation
Rock wool cultivation is a soilless cultivation mode in which plants are planted in pre-made rock wool blocks. With modern technology such as the integration of water and fertilizer, it can greatly improve the growth rate of vegetables, improve the yield and quality of vegetables, and reduce the production cost. The rock wool cultivation model has been widely used in Dutch facility agriculture, and has also been widely promoted in domestic agricultural parks.
3. Hanging cultivation
Hanging soilless cultivation is in the intelligent greenhouse, the use of hanging can lift drip irrigation system, the mode of cultivation tank can automatically lift, not only convenient for workers daily pruning, pollination, fruit picking and other operations, but also improve the bottom of the plant ventilation and light conditions, is conducive to reduce pests and diseases, improve the yield and quality, suitable for strawberry, tomato and other crops planting production.
4. Trough cultivation
The trough substrate culture is made of PVC pipe and fixed on the ground by iron support. The integrated irrigation system of water and fertilizer can be realized by filling the matrix and matching the drip irrigation belt. The facility is easy to install and use, strong integrity, less substrate consumption, low cost and low cultivation risk; The nutrient solution can be recycled.
5. Shallow flow cultivation
Shallow flow culture refers to a kind of hydroponics in which nutrient solution flows from the higher end to the lower end in the form of shallow flow in the planting tank. The shallow liquid flow is characterized by the membrane-like flow of circulating liquid flowing through the bottom of the cultivation tank only with a shallow liquid flow a few millimeters thick. The roots of hydroponic crops contact the shallow liquid flow to absorb water and fertilizer, and the upper part is exposed to moisture to absorb oxygen, which better solves the contradiction between root water absorption and oxygen absorption.
6. A frame farming gutter
A frame farming gutter system is composed of A-frame support, cultivation tank, cultivation medium and water and fertilizer irrigation network. This three-dimensional cultivation mode can make full use of space and solar energy, improve crop yield and quality, and can plant small fruits and vegetables, strawberries and leaf vegetables.
7. Three-dimensional pipeline cultivation
Three-dimensional pipe cultivation by a number of PVC pipe and brackets combined into a multi-layer three-dimensional cultivation system for nutrient solution circulation, PVC pipe are provided with planting holes for planting crops, part of the plant roots into the nutrient solution to absorb nutrients, the whole system to meet the needs of plants for water, fertilizer, gas, suitable for lettuce, celery, leaf beet and other vegetables planting.
8. Bowl type column cultivation
The vertical bowl culture consists of a bowl-shaped planting container connected along a square PVC pipe. The cultivation mode of planting crops is filled with matrix in the cultivation bowl, and the three-dimensional cultivation is realized with the liquid supply and return pipeline system.
9. Spiral pipe cultivation
Spiral pipe cultivation is the use of PVC pipe combination into a double spiral shape, the pipe installed drip irrigation system to provide nutrients and water for crops, so as to achieve three-dimensional planting cultivation mode.
