Potato is a vegetable that people often eat. It can be processed into snacks or cooked. It has high nutritional value and is planted in northern China. In recent years, with the economic development of China, potato cultivation has changed from artificial planting to mechanized cultivation. It is about the mechanized cultivation techniques of mid-late cooked potatoes. You can refer to å“Ÿ.

1 Preparation before planting potatoes

1.1 Selection of land

It is necessary to select a flat, mechanized micro-acid land with a slope of less than or equal to 15, which is fertile, has a deep soil layer and has the advantages of transparency, fertilizer retention and water retention.

1.2 Selection of 茬

Don't choose to repeat. Instead, we should choose land and fields that have not been planted with Solanaceae crops for 3 years and more. The former is best based on the cultivation of millet and beans.

1.3 To plow the land

Planting potatoes requires more than 20 cm of loose soil with loose and deep features. Fertilize before sowing in spring and autumn, use mechanized tools to carry out deep loosening and deep ploughing. Deep ploughing should be between 20 and 25 cm, then repressed, and make it flat, loose and lame before planting.

1.4 Preparation for cutting, process, follow-up

Before cutting, it should be noted that less than 50 grams of potatoes can be directly sown. In addition, the tools should be sterilized when cutting.

In the process of cutting (here, >50g seed potato), the cutting is carried out according to the requirements of the machine operation. There are three points to note at this time.

First, you need to pay attention to the use of the top advantage when retaining the top bud;

Second, to ensure that each is 40g, the top is slightly smaller and the tail is slightly larger, such potato chips are most suitable and more convenient;

Third, the dicing is cut into a prismatic shape;

Fourth, ensure that each cut has two buds. The specific operation is as follows: divide the potato chips of about 50g from the top of the bud eye into two parts, and ensure that each dicing retains the top bud; when cutting the big potato, it is more convenient to operate from the tail. Finally, divide the top of the bud eye part into two parts.

After the seed cutting operation is completed, the medicine such as the nail tray and the methyl thiophanate is sprayed and sterilized.

2 Mechanical process of sowing potatoes

2.1 Seeding time

The sowing time of the raking land is probably from late April to mid-May. The time of planting was postponed based on the soil conditions at the time.

2.2 Mechanical selection

When selecting machinery, you can choose to configure the tractor before the power of 20-60KW. The corresponding tools and seeders also have specific types, namely 2CMPF-2 and 2BMF-2.

2.3 Adjusting the seed drill

2.3.1 About the amount of seeding

The amount of seeding can generally be adjusted by varying the spacing between the seeds and their flow rate. When making adjustments, the seeds and fertilizers are filled into the seed box and the fertilizer box, and the frame is supported underneath, so that the ground wheel leaves the ground and is free to run and rotate. The ground wheel is then rotated at normal working speed to obtain the quality of the seed and fertilizer.

2.3.2 Adjustment of seeding depth

Loosen the opener and secure the bolts, and move them up and down to adjust the seeding depth, and ensure that the height of each opener is the same.

2.3.3 Adjustment of sowing ridge height

Adjust the ridge height by adjusting the height of the ridge shovel.

2.4 Ways of planting

The potato should be planted in a wide and narrow row. The plant spacing should not exceed 40 cm. The row spacing between the rows should be 66 cm, the plant spacing should not exceed 40 cm, and the seeding depth should be about 10 cm. Note that it is necessary to complete the five steps of fertilization, sowing, and ridges.

3 About the management of Daejeon

3.1 Mechanized soil

After the Miaoqi, the steps of timely cultivating and weeding should be done. Combine the cultivating with the soil in two or three times, and then cultivate the soil for the first time after the seedlings; the second cultivating and Weigao soil will be carried out in the bud stage; the last soil should be cultivated before and after the ridges are closed, and at the same time, the soil should be more, and the mound is larger. In this way, it is effective to ensure that the potato base grows in the loose soil.

3.2 About the prevention and treatment of pests and diseases

3.2.1 Pest Control

The pesticides for controlling underground pests such as zinc or phoxim particles will be fertilized and sown; and other pest control measures will be taken for the three pests of aphids, 28-star ladybugs and spotted locusts. For aphids, imidacloprid can be used for prevention, and later, it can be controlled by spray; with high-efficiency cypermethrin, it can control 28-star ladybug; the third pest can be effectively prevented with high-efficiency cypermethrin and bacground. treatment.

3.2.2 Disease prevention

Agricultural control, raising the level of farming and cultivation. For chemical control, the potato is protected and controlled by various corresponding and effective agents.

3.3 Cutting

Within 15 days before harvesting, cutting off the stems and leaves of the ground and transporting the plots or spraying 3% copper sulphate solution and spraying the weeds to kill the weeds can achieve the purpose of digesting tubers with Phytophthora infestans.

4 mechanized harvest

Mechanized harvesting can promote the cultivation of large areas of potatoes, and its work efficiency is particularly high. When the receipt is completed, the machine should be disinfected to avoid the spread of the virus. Pay attention to the lightness during transportation to prevent the skin from being damaged. At the same time, the effects of rain, frost and sun on the potato should also be avoided. Finally placed in the pergola for 15 days and then picked it into the warehouse.

In recent years, with the development of China's economy, our agriculture has been transformed from artificial planting to mechanized planting, which has greatly improved the agricultural planting output. Potato is a kind of mechanized planting, which can greatly improve the efficiency of agricultural planting. The above is detailed. The operation steps can be used by everyone.
