Standardized potato cultivation techniques

1 selection

On the basis of virus-free seed potato, good seed potatoes such as Zaidabai, Dongnong 303, Jinyin 8 and Eugene 88-5 were selected.

2 kinds of potato processing

Select a representative, disease-free, virus-free seed potato, and plant a week before sowing. Cut the knives when cutting the potatoes to use 5% to disinfect the children. Each potato block should be more than 25 grams to ensure that each potato block has 1-2 buds. Conditional farmers can use small whole potatoes to sow.

3 selection

The cultivation of potato plots requires the selection of loose soil and well-drained plots and the implementation of three or more crop rotations. The former crop is dominated by corn bran, followed by soybean bran, mixed grains, bogey beets, and vegetables.

4 site preparation

The cultivated potato plots are all deep-falling in autumn, with a depth of 23-25 ​​cm. The conditional plots can be used for deep-soiled soil preparation by all-around deep-soiled site preparation machines, and they all have good ridges to reach the sowing state.

5 base fertilizer

Hectares organic fertilizer content of more than 8% of high-quality fertilizer more than 15-20 tons, diammonium phosphate 225 kg, 75 kg of potassium sulfate or the use of equal amount of compound fertilizer, a deep application as a base fertilizer, and do seed fertilizer separation.

6 sowing

6.1 Sowing period

When the temperature is stable through 6-7 °C, timely sowing. In general, sowing will begin on April 25. All broadcasts will be completed before May 5.

6.2 broadcast method

Mechanical sowing or artificial seeding. Request to sow, cover soil and suppress continuous operations.

6.3 Density

Early maturing varieties and high-fertility plots should be properly planted, and late-maturing varieties and relatively low-fertility plots should be appropriately sparsely planted. The average hectare is 83,000-100,000 strains, and the seeding volume is 1800-2100 kg.

7 Field Management

7.1 Cha Tian fills seedlings

After the Qi Qimiao seedlings were fielded, so that the whole seedlings could be achieved.

7.2 Cultivated weeding

After the potato was sown, it was smashed and smashed three times. The first time after the emergence of the seedlings, the height of the seedlings was 2 cm deep, ie, the head of the soil. The second time, when the seedling height was 10 cm, the soil was thickened and the soil was met. The last time the seedlings were squatted before the budding was applied. Landscaping to take a big grass.

7.3 outside the top dressing

When the height of the seedling is 10 centimeters, the combined haze will be used to recover 150 kg of urea. Afterwards, the defertilizer can be sprayed with potassium dihydrogen phosphate.

7.4 Pest and Weed Control

7.4.1 Underground pests

Combined fertilizer application before sowing, hectares use 48% of 2250 ml of Le Siben EC, mix fine sand or fertilizer, and prevent and control underground pests such as goldworms and cockroaches.

7.4.2 Chemical Weeding

After the sowing, hectares of hectares were closed with 1500 g of 10% acetochlor and 20 kg of exchange water with 450 kg of water.

7.4.3 Disease Prevention

Late blight: In the early stages of potato late blight, foliar spraying was performed with 72% DuPont Kelu 800x or Kimreda Meer 500 times, and sprayed once every 5-7 days.

Virus disease: all potato virus-free seed potatoes.

8 harvest

8.1 Harvest

Choose sunny harvest during physiological maturity, and it is forbidden to harvest in rainy season so as to avoid dragging water.

8.2 Harvesting method

Use mechanical or artificial harvest methods. Artificially broken ridges are required to be ridiculed, not to run away, not to be paralysed, to pick out the light, and to pile up and cover the soil in the field to prevent it from drying out into sweet potatoes.
