Several potato sowing and planting machines
1. 2BMF-2 potato seeder: this machine is matched with 8.8 kilowatts ~ 12 kilowatts (12 horsepower ~ 16 horsepower) small four-wheeled tractors, which can complete ditching, fertilization, sowing, soil covering and other operations at one time, and has the characteristics of labor-saving, labor-saving and easy to adjust and use. Main technical parameters: seed fragmentation rate ≤ 1%, double plant rate ≤ 8%, hole rate ≤ 2%, productivity 4 mu / hour.
2. 2BXSM-1B potato fertilizer planter: this machine is an ideal potato planter in dryland flat farming areas. According to the agronomic requirements of these areas, on the basis of absorbing and digesting the advanced technology at home and abroad, one-way double-share plough is used as the carrier of fertilization mechanism and planting mechanism, and the driving ground wheel is added as the power source of fertilization and planting. Matched with small four-wheeled tractors, it can complete ditching, fertilization, planting, soil covering and other operations at one time. The main working parts include an one-way double-share plow, a spoon planting mechanism and a tooth rod fertilizer discharge mechanism. Main technical parameters: matching power 11 kW ~ 13 kW, working speed 2.09 km / h (file I), row spacing 36 cm ~ 50 cm (adjustable), plant spacing 25 cm ~ 45 cm (adjustable), sowing depth 10 cm ~ 18 cm (adjustable), productivity 0.07 ha / h, seed leakage rate < 2%, maximum fertilizer application rate 900 kg / ha, machine quality 179 kg.
3. 2BSF-2 potato planting machine: it is developed and produced by large agricultural machinery station in Qinyuan County, Shanxi Province. The machine is matched with 8.8 kW ~ 13 kW small four-wheeled tractor. It can adjust the plant distance and planting depth according to the requirements of farmers, and can complete the processes of fertilization, planting, soil covering and suppression at one time. Main technical parameters: row spacing 500 mm ~ 700 mm, plant spacing 400 mm ~ 500 mm, planting depth 100 mm ~ 150 mm, productivity 0.3 ha / h.
4. 2C-2 potato planter: it is developed by Haimen Agricultural Machinery extension Station of Jiangsu Province, which absorbs the advanced technology of many domestic models, and is mainly suitable for the planting of potato, radish and root herbs in the south and north. The machine is powered by S195 diesel engine and matches the chassis of Dongfeng-12 tractor to complete planting operation. it has the characteristics of flexible steering, convenient movement, high working efficiency and so on. The application of this machine not only saves time and effort in planting and harvest, but also greatly increases the crop yield after drilling holes. Main technical parameters: hole diameter 8 cm, hole depth 12 cm, row spacing 40 cm, spacing adjustable.

High-yielding Cultivation Models of Several Potato Species
In recent years, Potato Association of Ziyang District in Yiyang City actively explored potato high-yield cultivation mode, and carried out continuous demonstration planting in Xiangpulun Township, Yingfengqiao Town and Changchun Town, forming a complete set of high-yield cultivation technology system. Spring potato-double cropping rice cultivation. Spring potato selection "Dongnong 303" and other early-maturing varieties, from mid-late December to early January next year sowing, late April to early May harvest. Early rice is selected from late-maturing varieties, and the seedlings are sown sparsely or raised in two stages.

Matters needing attention in harvesting potatoes by machine
When harvesting potatoes by machinery, in order to save time, labor and labor, and to improve the economic benefits of the use of machinery and the commodity rate of potatoes, we should pay attention to the following problems. The main results are as follows: (1) about 10 days before the harvest time, the seedlings should be rolled or cut first (the method of rolling seedlings is to thread the waste tires into a string and drag the seedlings with a tractor) to make the potato skin aging and prevent the potato from breaking during harvest and affecting the quality of commercial potato. (2) the matching of potato pickers for each unit should be reasonable, and the small harvester should be equipped generally.
