Intelligent Agriculture "occupies" Beijing Agricultural Carnival

Original title: intelligent Agriculture in Agricultural Carnival

The fourth Beijing Agricultural Carnival is being held in Changping District, Beijing. Agricultural Carnival takes farming culture, creative agriculture, agricultural high and new technology as elements, attracting urban people to come for sightseeing, which is not only an opportunity for urbanites to get close to agriculture and return to nature, but also a platform to show the latest achievements and technologies of agriculture. Today (23rd), we will show you--

Growing vegetables indoors, nutritious and environmentally friendly

If you are a person with high requirements for food safety and want to grow vegetables and eat on your own, then you can move a "multi-layer fine leaf cultivation cabinet" home. Multi-layer fine leaf cultivation cabinets can grow rape, chrysanthemum chrysanthemum, spinach, parsley, shepherd's purse, rape and other small leafy vegetables. Generally adopt two-layer or three-layer structure, spread soaked non-woven cloth on the planting board of each layer, sow the seeds of sprouts on the planting board, and then lay them with ceramsite to protect moisture and fix plant roots. Traditional soil cultivation is time-consuming, poor controllability, and easy to breed germs and attract mosquitoes, which is not conducive to indoor application. The multi-layer thin leaf cultivation cabinet overcomes these shortcomings.

Trees can be planted in the office

White-collar workers usually work in high-rise buildings, what they lack is a little natural green, and what they yearn for is a little poetic green. What is more fierce than putting a few pots of green plants in the office is to move the office to the middle of the green plants and imagine a working environment that smells of grass and thinks about copywriting. Urban micro-ploughing technology, which applies soilless cultivation and hydroponics to buildings, allows people to symbiosis with plants, and vegetables can be produced in any space and corner, which not only increases the humidity of the office, but also is a green landscape.

Fish farming, no water change, vegetable planting, no fertilization.

In the future, the fish tank of office workers can be like this: the fish tank is divided into two, with cream lettuce on the water and fish in the water. There is a net between the two parts. although the roots of lettuce are soaked in water, they do not extend into the water as far as possible, so that the fish will not eat the roots of lettuce, otherwise the roots will be eaten up by the fish before the leaves grow out. Cream lettuce is neither medicated nor fertilized. all the nutrients needed come from fish dung in the water, and the root system of cream lettuce can also help fish tanks purify water.

The fish-vegetable symbiotic farming system combines aquaculture and vegetable production, which are two completely different farming techniques, to achieve scientific symbiosis through ingenious ecological design, so as to achieve the ecological symbiosis effect of fish culture without changing water without water quality worries. the ecological symbiosis effect of growing vegetables without fertilization. The water from aquaculture is transported to the hydroponic cultivation system, where microbial bacteria decompose the ammonia nitrogen in the water into nitrite and nitrate alkali, which are then absorbed and utilized by plants as nutrients. To achieve a harmonious ecological balance among animals, plants and microorganisms is a sustainable recycling zero-emission low-carbon production mode in the future.

Vegetables "chasing the sun"

If you can show a dynamic picture on the paper, you will find that all the vegetable pots move slowly along the track, and the vegetable pots rotate around themselves. This is the rotary light-chasing cultivation facility. With the rotation of the orbit, each plant gets plenty of light, which in turn improves the quality of vegetables. This set of equipment is equipped with a sensing device, which can sense the humidity of the leaves of vegetables, and can realize fixed irrigation and fixed-point harvest through computer programs and parameters set by the touch screen controller, which can save more than half of the labor cost. at the same time, the planting efficiency is more than three times that of other planting methods.

Tomatoes planted in sponges

The tomatoes here are very sweet and contain 6% to 10% more sugar than ordinary tomatoes. This is the cultivation mode of low-stage close planting of high-sugar tomato. Using sponge as matrix has the advantages of environmental protection and non-toxic degradation. Only 3-5 panicles of fruit are retained in the plant growth stage, so that the fruit can fully absorb nutrients. Reasonable close planting is a reasonable arrangement of crop planting within a specified area, which is beneficial to make full use of light energy and improve photosynthetic efficiency. The advantage of this cultivation model is that the cultivation environment is stable, the labor force can be used flexibly, and four crops can be planted every year.

Vegetables float on water

Seen from afar, they look like flowers blooming on the surface of the water, but in fact they are vegetables grown by floating cultivation. The seeds were planted in the seedling substrate, and the foam disk equipped with the seedling substrate was floating on the water surface, so that the seedlings could fully absorb water and nutrients from the substrate and water bed, and take root and grow. Floating cultivation is used in a completely controllable environment, and the nutrient solution is recycled in a closed system, which can save water by more than 90%, avoid the spread of soil-borne diseases and reduce the use of pesticides.
