Two Methods of Raising Seedlings

At present, there are two mainstream seedling raising methods, one is dry seedling raising using plastic seedling trays, and the other is hydroponic floating seedling raising using EPS foam seedling trays.

7 Days to Grow High-quality Fodder

The vertical planting not only saves Land resources, saving time and labor, high planting yield. The pasture is mainly wheat, which can grow 15-20 centimeters in 7 days, saving feed costs and water resources. The cost of producing such maltgrass is less than 1 cent per kilogram.

What kind of plants can a plant factory grow?

Most people would probably answer the higher yielding leafy vegetables. However, 5 categories over 130 types of plants have entered the plant factory currently.

Mobile Plant Factory - Planting Options in Extreme Environments

A 40-foot container can plant 5,000 leafy vegetables, which is equivalent to the output of two acres of land, and one crop can be harvested in 28 days. Mobile plant factories are a good choice for planting in extreme environments.

Can Vertical Farming Hold up the Future of Farming?

Vertical farming heralds a future where our food may be grown in small spaces in our cities and under our feet. But can it really hold up the future of farming? How far can it go?

Ebb and flow table can Increase flower production by 2-4 times

Ebb and flow table growing system can solve the contradiction between irrigation and oxygen supply, and it is an agricultural technology worthy of promotion and application.

The method of growing seedlings in substrate plug trays

Calculate the number of plugs used according to the cultivation area, select a suitable plug tray, arrange and disinfect the mixing site

Advantages of Vertical Planting - Strawberries

vertical planting is a planting method in which two or more crops are planted on the same farmland in a multi-level and time-based manner.

Pepper Transplanting Management

The seedling period reaches 55--60 days. Peppers grow 7-10 true leaves. After the late frost, the soil temperature at a depth of 5 cm is stable above 15°C and can be planted.

Pepper Seedling Management

The quality of pepper growth depends on whether there are strong seedlings planted at the beginning

Plant factories need to produce crops in a closed environment, so it is necessary to build related supporting equipment including external maintenance structures, air-conditioning systems, artificial light sources, multi-layer cultivation racks, nutrient solution circulation and control systems, and computer adjustment and control systems.


Industry-related research and analysis found that the cost of building a plant factory with an area of less than 1,000 square meters (including interior decoration, equipment, and facilities) is between 2,100 and 2,900 US dollars per square meter; The cost is US$1,200-1,500; for a large plant factory with an area of more than 10,000 square meters, the construction cost will drop to US$1,200 per square meter. Among them, artificial lighting equipment accounts for the largest proportion of all equipment costs, especially in plant factories that fully use LED light sources, LED costs often account for about half of the total equipment cost.


Post-production and operation costs mainly include electricity costs, various materials (nutrient solution, seeds, CO2 gas fertilizer), labor costs, material transportation costs, personnel management costs, etc.
Now electricity costs account for about 25% of the production and operation costs of plant factories. "An industrial plant with a height of 10,000 square meters and a height of 4 to 5 meters is transformed into a plant factory with artificial light, and the annual power consumption is more than 13 million kWh." High energy consumption It has been regarded as one of the main bottlenecks affecting the development of plant factories.


To solve the problem of high energy consumption, there are the following directions

One is to improve the photoelectric conversion efficiency. Optimize the use of light sources by optimizing the design of light sources, spectra, and environments.


The second is to use off-peak electricity. Plant factories can make use of low valley electricity at night to supplement and adjust light sources for crop growth. This not only reduces the electricity cost of the plant factory, but also plays a role in peak-shaving and valley-filling of the entire electric energy application, improving energy utilization efficiency.


Third, some measures to save electricity are also necessary. Different crops require different light environments. The longer the photoperiod, the better the growth quality and the faster the growth speed. Plant factories can find the best balance between light and plant growth, and find the optimal power consumption. model.


Fourth, actively explore the use of clean energy. For example, the application of solar photovoltaic power generation systems, wind energy, hydropower or biomass energy and other environmentally friendly power generation methods has become a hot spot in the research of plant factories.
