How to Planting Grapes Without Soil
With the development of soilless cultivation technology, more and more crops can be cultivated without soil, and the basic materials for soilless cultivation can be recycled, so it has the characteristics of water saving, fertilizer saving, environmental protection, high efficiency and high quality. Let's take you to understand the soilless cultivation technology of grapes.
1.Simple Device
The simple device is mainly composed of three parts: preparation and supply of nutrient solution, cultivation parts, and reflux of nutrient solution. The preparation and supply of nutrient solution are mainly composed of nutrient solution preparation and storage tank, mixing pump, liquid supply pump, drip irrigation pipe. It consists of components such as filters and controllers. The cultivation parts are mainly composed of cultivation tanks or pots, tree supports and other one. The reflux of nutrient solution is mainly composed of return pipes and other components.
2.Use of Nutrient Solution
The nutrient solution was replaced every 30 days before and at the initial stage of grape germination, and the nutrient solution was replaced every 20 days when the new shoots began to grow, and the nutrient solution was generally replaced 5 times. The nutrient solution is circulated once 1-3 days before germination, and the nutrient solution is circulated once 3-5 days after germination.
During the flowering stage, the nutrient solution is changed every 20 days, generally 4 times, and the nutrient solution is circulated every 3 to 5 days; from the deciduous stage, the nutrient solution is no longer replaced, and the nutrient solution is circulated every 5 to 7 days. The temperature of the nutrient solution in the facility cannot be lower than 0°C, otherwise it is easy to freeze.
3.Precautions
When the temperature is high and the water transpiration is fast, the cycle interval of the nutrient solution should be shortened as appropriate. If the water loss is found to be too fast during the use period of the nutrient solution, it is necessary to add water appropriately to prevent the fertilizer damage caused by the excessive concentration of the nutrient solution.
The above is the entire content of the technical regulations for soilless cultivation of grapes.
