[news] China agricultural industry of agricultural mechanization is to enhance the efficiency of farming, the most direct means to improve the quality of agricultural products, the core of which is the variety of advanced agricultural machinery. It involves crop cultivation, irrigation, harvesting, pest control and other stages.

    What's the use of these agricultural machines? How do they work? How to achieve the purpose of improving efficiency and energy saving? Now, please look at it with reporters.

     Automatic seeder: improve seed survival rate

Compared with the traditional seeding method, the modern automatic seeder not only reduces manpower, but also improves the survival rate of seeds.

The farmers only need to put the seeds into the corresponding boxes, and adjust the amount of sowing and the amount of soil covering. Rice seeding machine by conveyor belt move the tray, the bed soil, watering, sowing and soil covering four operation process at one go, and reach the purpose of uniform seeding.

It is known that the seeding rate of the automatic seeder can reach 800 discs per hour, and it is only about two minutes when the amount of 1 mu sowing is calculated according to the calculation of 25 discs per mu.

But the traditional manual sowing method first nutrient soil plate, water, soil, and seed.

From the emergence of seedlings, mechanical sowing with the use of rice seedling special substrate, the emergence of neat and uniform, root system developed, sturdy stems, leaves standing upright, good color, no disease and insect infection. Compared with manual sowing, the mechanical seeding emergence is more consistent, better growth, more suitable for mechanical transplanting.

Drip irrigation belt: saving water and saving fertilizer

The traditional flood irrigation method will cause serious waste of agricultural water resources, water resources utilization rate is extremely low. Today, a long drip irrigation pipeline covering the fields has become an essential part of modern agriculture.

Drip irrigation is generally divided into whole pipeline irrigation and local micro irrigation, so that the leakage and loss of water are reduced to the minimum. At the same time, drip irrigation can timely supply the water needed in the root zone of crops, so that the utilization rate of water is greatly improved.

Not only that, but also the drip irrigation belt can be combined with fertilizer. When the chemical fertilizer is dissolved and injected into the irrigation system, the fertilizer nutrients can reach the crop root layer directly and evenly, and realize the "water and fertilizer synchronization", which greatly improves the effective utilization rate of fertilizer.

Drip irrigation belongs to micro irrigation. Water slowly and evenly penetrates into the soil, which can maintain the soil structure and form suitable soil water, fertilizer and thermal environment.

After using drip irrigation belt, it can reduce the amount of water and fertilizer, pesticide application, and the occurrence of diseases and insect pests, and can improve the quality of products obviously. Compared with the traditional irrigation method, the drip irrigation belt in greenhouse or greenhouse can greatly improve the output of the product, advance the time of listing, and the economic and social benefits are remarkable.

      Plant protection unmanned aerial vehicle: favored by farmers

In the vast fields, an aircraft plant protection UAV under the dance and the pesticide evenly sprinkle to each leaf crop...... In recent years, plant protection unmanned aerial vehicle (UAV) has been increasingly favored by farmers. The main reason is that it has the characteristics of energy saving, high efficiency, environmental protection and safety.

The rice pest control needs artificial carrying springing Dayao, farmers sprayed 1 acres per hour or so can spray pesticide. Not only the work labor intensity is big, the work time is long, and for a long time in the paddy field spraying the pesticide, ventilated, the light transmittance is bad, easy to cause the operator the medicine to be poisoned.

And a plant protection UAV a day can work in more than 300 acres, timely operations at the same time, it is not easy to overcome in the hilly area of the manual operation of the difficult terrain.

In addition, compared with the traditional artificial plant protection, the UAV plant protection water saving 80%-90%, save pesticide 30%-50%, insecticidal efficiency of more than 95%, greatly saving the cost of production.

It is understood that the cyclone lifting principle of UAV can be plant protection, plant leaf will be fully reversed, drug is sprayed on the abaxial surface of leaves and rhizome, better suppress pests, and does not pollute the soil, solve a "drug" difficult "chaos Dayao" problem.

Corn combine harvester: easy harvesting

With the continuous improvement of the level of agricultural mechanization, "drop of sweat drop eight petals" of the traditional model of autumn harvest no longer exists, a large number of agricultural machinery put into use, the farmers from the heavy labor liberation. During the autumn harvest season, the roar of motors was often heard in the corn fields, and the corn combine was shuttled across the vast farmland. The peasants finished the autumn harvest easily.

With the driving of a harvester, and the corn stalk soon as magically disappear, the machine "eat" in the whole corn stalk, spits out the skins are not Corn Cob, this process is completed in the blink of an eye. Ear cutting was carried out with corn harvester under the condition of corn growth, and the ear handle was pulled off under the action of stripper plate. Because of the difference between inside and outside roll height, the ear falls into the ear box, and the ear is filled and the stack is out of the box. The high speed rotating cutter cuts off the stalks from the roots and sends them into the shredder and cuts them into 3-5 cm long pieces. After chopping, the stalks fall to the ground.

Usually, one person can harvest one acre of corn a day without stopping, and the ordinary corn combine harvester can harvest 100 mu a day, which is equivalent to 100 times of manual labor, saving time and labor. Through mechanized operation, farmers' labor intensity is greatly reduced, and labor efficiency is effectively improved. In addition, straw returning can also increase soil fertility, increase grain yield and protect ecological environment.
