Plant factories are a trend in the future, and more and more farmers are willing to use this method for planting.
It’s not practical to plant a seed in the spring and wait until the fall grows fruit. Now the plant factory grows plants without the soil and the sun. You can eat what you want in a few days, it is very faster than before.
Lettuce seed is sown on a sponge. The roots are infiltrated into a special nutrient solution. The roots extend to the bottom through fine pores. The leaves thrive under the red and blue LED light. They are the latest products of “Plant Factory”.
3 Advantages Of Hydroponic Plants In Modern Agricultural
Advantage 1. Plant Factory Can Grow plants all year around
The following is a concrete example：
In the “plant factory” of Zhejiang University in Chun’an Town, Changxing County, project management staff Ding Wenya said that since the operation in October 2013, the “factory” is trying to solve such problems – three-dimensional soilless cultivation, plus With the intelligent control of the environment, as well as air and moisture, plants can freely grow free from other natural conditions.
“Plant Factory” is an 800 square meter fully enclosed experimental space. All items and personnel need to be professionally disinfected before entering. The walls are all made of double-layer insulation materials to block all external factors. The impact of pests and diseases is zero. In the “factory”, 18 multi-layer iron frames of about 20 meters in length and 8 meters in height were arranged in two rows, which were filled with lettuce. Each layer of the iron frame is surrounded by a tube, which constantly simulates the light band required for photosynthesis.
These lettuces are no longer day or night. They maintain a strong growth momentum throughout the day, the production rate is increased, the production cycle is shortened, and the annual output can reach 200,000 kilograms, 30 times that of ordinary open field cultivation.
Advantage 2. Hydroponic plant factory field system intelligent nursing
Now let’s see a new example:
“The sales of vegetables produced by the ‘plant factory’ are really good. They are picked up immediately after they are grown and shipped to customers.” Zhang Wenhua, chairman of Zhejiang Luyexian Ecological Agriculture Development Co., Ltd., said in an exciting way in the village of Chuanbu, Changxing Longshan New District.
In the company’s ordinary greenhouse of about 200 square meters, crops such as lettuce, leeks and bumps were planted on more than 150 round columns, and on the other side of the 14 A-shaped brackets. The seedlings of cherry radish and spinach have just emerged from the black soil. The shed is equipped with a fan and water curtain cooling system for the moisturizing and cooling of the summer season plants.
In addition, the semi-intelligent power control box replaces the fully intelligent computer control system. The staff can set the time and frequency with just a few push buttons, and the irrigation and fertilization of the plants can be done with a watering system mounted on the columns and supports. “What you see is not the soil, but the ‘matrix’, which is also a form of ‘soilless cultivation’,” said Zhang Ruixia, deputy director of the R&D Center. According to Zhang Ruixia, since the hardware facilities and operation modes of the “factory” are basically available, the production results from this are not inferior. If properly cared for, it can grow 20 to 22 baht a year, and the output of more than 200 square meters is equivalent to the output of 4 acres.
Advantage 3. High value of soilless cultured vegetables
Soilless cultured vegetables are non-polluting, pest-free, do not spray pesticides, and have high nutritional value. The price of hydroponic vegetables is within reasonable tolerance and has great market and development potential.
