The history of soilless cultivation can be traced back to ancient times. As early as the 6th century BC, the Hanging Gardens of Babylon adopted similar soilless cultivation techniques, planting plants in containers on the roof and maintaining plant growth through artificial irrigation. In modern times, soilless cultivation technology has been further developed. In 1840, German scientist Liebig proposed the theory of plant mineral nutrition, laying the theoretical foundation for soilless cultivation. In the early 20th century, American scientist Glick applied soilless cultivation technology to commercial production for the first time, pioneering modern soilless cultivation. Since then, soilless cultivation technology has been wide Hydroponics is the most common type of soilless cultivation. It involves immersing the roots of plants directly in a nutrient solution, which provides water and nutrients to the plants. Hydroponics can be divided into two types: static hydroponics and dynamic hydroponics. Static hydroponics is to fix the plants in a container without the nutrient solution flowing; dynamic hydroponics is to circulate the nutrient solution continuously through water pumps and other equipment, providing the plants with more sufficient oxygen and nutrients. Aeroponics, also known as aeroponics, is the process of atomizing nutrient solution into tiny particles and spraying the nutrient solution on the roots of plants through a spray device to provide water and nutrients for the plants. Aeroponics can greatly increase the contact area between plant roots and oxygen, and increase plant growth rate and yield. Substrate cultivation is to plant plants in a substrate, which provides water and nutrients to the plants. The substrate can be inorganic materials such as rock wool, coconut bran, perlite, or organic materials such as peat and bark. Substrate cultivation can be divided into rock wool cultivation, coconut bran cultivation, perlite cultivation and other types.

How to achieve high yield of greenhouse strawberries

JIANDA GREENHOUSE FACTORY PRODUCE GREEN HOUSE MATERIAL TO BE SHIPPING

"Wisdom fruit" grows in the greenhouse In a smart greenhouse, strings of peppers are growing upward along the traction rope. The roots are suspended in the air, and water and nutrients are accurately obtained through the drip irrigation system. Sensors in the greenhouse monitor temperature, humidity, light and other data in real time and automatically adjust the greenhouse environment. This is the epitome of modern facility agriculture, which is completely changing the passive situation of traditional agriculture "depending on the weather".

big span agricultural film greenhouse, gothic greenhouse

This is our big sawtooh greenhouse covering film projects.

This project have 3 sets greenhouse, which is 3000 square meter.

Jianda company have own factory, and have our own greenhouse accessory produce workshops.

vegetable greenhouses, most is multi-span film greenhouse, venlo big polycarbonate and glass greenhouse.

What system including in the multi-span greenhouse?

Natural ventilation systems for different greenhouse types.

In order to achieve natural ventilation, ventilation windows such as roof windows and side windows are set up in the greenhouse to form a greenhouse natural ventilation system. According to the different characteristics of each type of greenhouse, different ventilation window settings and ventilation window opening and closing types are adopted to determine sufficient wind window area to form different types of natural ventilation systems.

Venlo glass greenhouse is one of big agricultural house for planting vegetable, in order to control the climate for crops growing. the glass greenhouse covering 4mm glass in the roof and around walls, as while, have inner shading system, cooling system and heating system.

one of our customer visiting factory, our main products is film greenhouse, polycarbonate greenhouse and glass greenhouse
