Ginger potato planting method and time

Planting method: ginger potato is suitable to be planted in the land with loose and fertile soil, sufficient water source and good drainage and irrigation, after the soil is ploughed and the potato bed is ploughed and planted according to the plant distance of 20-40cm and hole depth of 5-6cm, phosphorus and potassium fertilizer and multi-element fertilizer can be applied in the whole growth process of ginger potato, when the seedlings grow to 15-20cm, it is necessary to set up the frame and use Nongle water soluble agent to control weeds. Planting time: ginger potatoes can be planted around March 20.

I. selection of sites

Ginger potato is generally planted around March 20 every year, and it can be planted in the land with deep loose and fertile soil layer, adequate surrounding water and good drainage and irrigation. Ginger potato is not suitable for continuous planting, and flood-drought rotation can be carried out.

Second, ploughing the soil

In the winter of the year before last, the soil should be deeply hoed or ploughed more than 30-50cm to let the soil bask in the sun, which is conducive to weeding, pest control, and promoting the growth of ginger potatoes. When the soil is close to white weathering, the soil will be dug into potato beds before and after the the Spring Equinox season in the second year. The height of the furrow is 30-50cm, and the border should be flat and round, digging deep to the fourth ring ditch to facilitate irrigation and drainage in the later stage.

3. Planting

After finishing the potato beds, each border was planted in 2 rows, according to the plant spacing of 20-40cm, the depth of the hole was 5-6cm, one seed potato block could be placed in each hole, and the incision was placed laterally and covered with soil.

IV. Fertilization

The main results are as follows: 1. The border can choose to withdraw application or point application, apply seedling fertilizer every 20 days or so after sowing, and then apply fertilizer every 30 days according to the growth of ginger potato.

2. In the whole growth process of ginger potato, phosphorus and potassium fertilizer and multi-element fertilizer are mainly applied. 46% urea and 16 jin of ternary compound fertilizer are used in the early stage, and 24 jin and 6 jin of urea are used in the later stage.

3. The total amount of fertilization per mu is about 340 jin, of which urea is about 100 jin, ternary compound fertilizer is about 200 jin, and potassium sulfate is about 40 jin. According to different soil conditions, the amount of fertilization is also different, according to the principle of light application in the early stage and heavy application in the later stage.

5. Weeding

Artificial or herbicide weeding should be carried out 20-25 days after sowing. 74.7% of the herbicides can be sprayed with 150g of water soluble agent per mu. Manual weeding is needed within the 10cm around the seedlings to avoid mistakenly spraying ginger potato seedlings. Weeding can be carried out according to the actual situation in the middle period, and weeding is needed about 6-8 times during the whole growth period.

VI. Cultivate the soil

45-50 days after sowing, the soil can be cultivated next to the plant every 35-40 days, and the soil can be cultivated 45-50 days after sowing. It is easy to harden the topsoil in case of rain, so the soil can be cultivated early. The key period of soil cultivation is in autumn and early winter, and soil needs to be cultivated 5-6 times during the whole growth period.

VII. Setting up a fight

Check and replenish the seedlings in time after emergence, and keep 1-3 buds in each hole when the seedlings grow to about 10cm. When the seedlings grow to 15-20cm, you can choose to use hard straight bamboo poles or branches with a length of 2-2.5m. Each plant can stand upright and let the vines climb and grow on their own.

8. Irrigation

Generally speaking, there are more Rain Water in the first half of the year, so it is necessary to take good drainage measures. if you encounter hot and dry weather, you can sprinkle water in the morning and avoid deep irrigation. Early irrigation can be dry and wet, and there is a relatively large amount of water from July to September. Deep irrigation can be carried out during autumn drought in August-September, late irrigation can be drained early, and "walking horse water" can be used to moisturize and prevent immersion in October. The Beginning of Winter should stop irrigation to keep the potato border soil dry and loose.
