The black technology in the field promotes the re-shaping of Chinese agriculture
[China Agricultural Machinery Industry News] As a big agricultural country, China's agricultural development has undergone many changes, but it has not liberated people from hard work, but soon, China's agriculture is about to change. Because, on the ground in the field, these black technologies have appeared.
The black technology in the field promotes the re-shaping of Chinese agriculture
1, rice transplanter
In the past, farmers' transplanting was often inserted into a seedling, and the efficiency was not high. In addition, artificial transplanting had a certain error in the spacing and planting status of the seedlings. Now, the emergence of rice transplanters has greatly improved these problems. It is understood that a rice transplanter can now complete the work within 15 minutes, and can ensure that the inserted seedlings are regular and orderly.
2, planter
Planters are often used for grain sowing, corn hole sowing, cotton sowing, pasture sowing, etc. The planter is now able to achieve precision seeding abroad. In the planter equipment, in addition to the perfect land preparation, soil covering, repression and fertilization, sprinkling pesticide equipment, its seeding device is installed with a variety of pneumatic seeding principles and mechanical seeding to ensure single seed precision sowing .
The advantage of the planter is that it can complete multiple operations at a time, high efficiency, ensure timely seeding, increase production, and make full use of supporting power to save energy and reduce operating costs. Compared with the traditional seeding method, the labor cost of joint seeding labor is reduced by about 30%.
3, plant protection drone
At present, most domestic farmers still use manual knapsack sprayers to spray pesticides. The effective utilization rate of pesticides is very low, and it is easy to cause environmental pollution. On the other hand, its control effect is very poor. In order to kill insects, farmers have to use pesticides to spray repeatedly. As a result, a vicious circle of “opium treatment†has been formed. The important point is that the farmers use pesticides in the back of the pesticide box. Therefore, it is very likely that the pesticide will wet the clothes after spraying for a few minutes, and there is a hidden danger of pesticide poisoning.
Spraying with a drone can greatly improve efficiency, and the application time per acre is only 1 minute. At the same time, when using the drone spraying operation, when the liquid droplets are ejected from the sprinkler, the downward flow of the rotor is accelerated to form an aerosol flow, which directly increases the penetration of the liquid droplets on the crops and reduces the pesticide. The degree of loss, and increase the deposition and coverage of the liquid on the target crop, so that the "drug" and "water" are lowered, and the treatment effect is raised.
4. Agricultural weather station
The agricultural meteorological station is a crop meteorological detection system designed for the monitoring of crop growth environment and disaster monitoring and early warning. It can be used to measure wind speed, wind direction, ambient temperature, ambient humidity, atmospheric pressure, rainfall and other factors.
With the agricultural weather station, users can directly access the data through the browser, and implement over-limit alarms on the parameters, so that agricultural plant users can scientifically manage economic crops. The agricultural gas field agricultural field weather station can provide data basis for the meteorological management department to know the local agricultural meteorology in real time.
5, combine harvester
In general, agricultural harvesting is very troublesome. In the case of rice, the traditional harvesting requires manual harvesting of the rice in the field and then threshing, and then removing the impurities generated during the threshing process, which is very cumbersome.
However, with the combine harvester, harvesting, threshing, separation, clearing, and grain gathering can be realized, greatly reducing the labor intensity of farmers. At the same time, the combine harvester also has the function of “satellite command harvestingâ€, which can realize remote positioning, remote monitoring and remote “diagnosisâ€.
6, soilless cultivation techniques
Compared with soil cultivation, soilless plants have a fast growth rate, a short growth cycle and a strong growth. For example, 60 days after sowing of watermelon, the plant height, leaf number and relative large leaf area of ​​soilless culture were 3.6 times, 2.2 times and 1.8 times of soil cultivation, respectively; the crop yield could be increased exponentially.
Soilless cultivated crops not only have high yield, but also good quality, clean, tender and pollution-free. In addition, it can also apply a variety of mineral nutrients according to crop needs. The birth of soilless cultivation technology has freed crop production from soil constraints and greatly expanded the available space for agricultural production.
7, photovoltaic agricultural greenhouse
Photovoltaic agricultural greenhouse is a greenhouse that integrates solar photovoltaic power generation, intelligent temperature control system and modern high-tech planting. By erecting solar panels with different light transmittances on agricultural greenhouses, it can meet the lighting needs of different crops, and can plant various high-value-added crops such as organic agricultural products and valuable seedlings, and can also achieve off-season planting and fine planting.
Photovoltaic agricultural greenhouses can focus on the development of organically produced vegetables, edible fungi and Chinese herbal medicines, moderately develop ornamental seedlings, and increase the added value of unit land output and agricultural products. In addition, it can also be developed into a special tourism project.
