At 10 o'clock in the morning, Tan Baolin in his 50s entered the vegetable greenhouse. "It's time to listen to music." He walked up to a one-foot-tall green instrument and pressed the play button. Suddenly, there was a monotonous and low-level " The sound of buzzing filled the entire greenhouse.
God! This is also called music? The reporter's patient son listened for 3 minutes and it was really annoying. Tan Baolin laughed. "You think it's noise, but the dishes in this shed are lovely. Every hour in the morning and one in the afternoon, not only grow faster, but the output can increase by 20%!"
It turned out that this "bang" strange instrument called "sonic wave instrument." This month, Changping District will host the first agricultural carnival in Beijing and will focus on displaying more than 10 new agricultural technologies. This is one of them. In the “Vegetable Forest†exhibition area that Tan Baolin is responsible for, Sonic waves have been greatly enhanced.
“You see, just a few days after this lettuce was planted, it has already been so high.†At the edge of a small vegetable field in the garden, Tan Baolin pulled a fresh green leaf of more than a dozen centimeters high. Rejoicing, "Look at this growth, at least than the ordinary greenhouse dishes can be harvested in advance for seven or eight days."
Acoustic waves help to speak of God's spirit. In principle, Lao Tan himself is also confused. It was actually the science and technology person in charge of the exhibition area that opened the mystery to reporters. Originally, this instrument applied sound waves of a specific frequency to the plants through sound vocalization. After the sound waves were stimulated, the vitality of the plants was significantly improved, and the absorption, synthesis, oxidation, and reduction ability of the root system were all effectively promoted. It becomes very strong.
The sound wave booster in the garden can emit 9 different sounds. Tan Baolin gave a demonstration to reporters one by one: "Hey -", "Yeah -", "Yeah -" ... all-in-one monotonous and low-lying, "Not how nice it sounds, but experiments have proven that plants like it!" Tan told reporters that because of the "Music edification" of two hours a day, the strawberries planted in the garden last year were 15 days earlier than ordinary greenhouse strawberries, and they tasted sweeter.
Not only is the sound waves helpful, but in this “vegetable forest†exhibition area, there is also a method of growing vegetables called “aerosol cultivationâ€, which also gives the reporter a whole new look.
Hydroponic culture and matrix culture have become quite popular in agricultural production in recent years. To put it plainly, it is to grow vegetables in nutrient solution or in a substrate prepared with peat soil to increase production. What is the problem of "aerosol culture"? Tan Baolin led the reporter to the mint production area.
The peppermint in front of him did not grow on the ground, nor grew on the shelf, but grew on a slope of the foam plate that was tilted at 45 degrees. The two oblique planes are offset to form a three-dimensional triangle, planting space has increased twice as much as flat planting. But what's strange is that there is no pipeline on the foam board. How can the plant be fed?
"Mystery is behind the board." Tan Baolin unloaded one of the foam boards, and the moist water vapor was blowing. There are three rows of supporting steel frames behind the original foam plate, and there is a spraying device every 50 cm on the steel frame. The nutrition liquefies into small droplets to moisten the bare roots of the plants.
"The benefits are: first, saving water, and second, preventing disease." The technicians told the reporter that for every kilogram of leafy vegetables produced by aerosol cultivation, only 10 kilograms of water is needed, which is one-fortieth of that of ordinary grown vegetables. One quarter of vegetables. Because it grows in the air and does not touch the soil, it is also difficult to be attacked by germs.
Saying goodbye to the “aerosol cultivation†of vegetables, the reporter was again hung on top of a red box that drew the wind. The red box reads the words "carbon dioxide generator." It is also connected to a liquefied gas tank at one end. “This is the way to add carbon dioxide to plants through gas combustion.†According to the technicians, just like people can't leave oxygen every day, plants cannot grow without carbon dioxide. In winter greenhouses, a certain temperature must be maintained, ventilation and ventilation will not be frequent, and the concentration of carbon dioxide will easily become low. Over time, the photosynthesis of plants will be affected.
“Supplementing carbon dioxide is the key to high-yield and stable production in the greenhouse in winter.†According to the technicians, previous experiments have proved that when the other growth environment is fully met, when the concentration of carbon dioxide in the environment reaches 1000 to 2000 ppm, the crop can increase production by more than 40%.
In the agricultural carnival exhibition area, the novelty of agricultural technology is far more than this. The vegetables are planted on the spiral pipe, and insecticides are not used to kill insects. The reporter walked and watched and lingered.
From the 23rd of this month, the Beijing Agricultural Carnival will officially kick off. More than a dozen new types of agricultural science and technology, such as sound waves, will move from here to the vast land of the Beijing suburbs.
