Planting method and time of ginger potato

When planting ginger potato, it is best to choose sandy loam planting, generally not continuous cropping, can implement rice-drought rotation. Specifically, according to the plant spacing of 20~40cm, the hole depth of 5~ 6 cm, put a potato piece, apply phosphorus and potassium fertilizer or multi-element fertilizer once every month or so, keep the soil moist. In addition, after planting about 20 days in addition to a grass, 45~50 days to cultivate a soil, in a timely manner after the emergence of seedlings can be thin seedlings, planting, generally before and after the spring equinox planting best.

Specific cultivation methods of ginger potatoes:

1. Land selection: It is preferable to select deep loosening and fertile soil layer. The garden field shall be planted on the land with sufficient surrounding water source and good drainage property as far as possible. Generally, it is not suitable for continuous planting. Paddy and dry rotation can be implemented.

2. Cultivate soil: in the winter of the previous year, deep hoe or deep ploughing of more than 30~50cm shall be carried out first, so that the soil can be sunburned to achieve the effect of weeding and pest control. It will be beneficial to the growth of ginger potato when it is nearly white and weathered. Before and after the spring equinox of the coming year, the soil will be scattered into potato beds, the height of the furrow is about 30~50cm, the surface of the bed is flat and round, and the four-ring furrow is dug deeply to facilitate irrigation.

3. Planting: After covering the potato beds, plant two rows in each bed, plant spacing 20~40cm, hole depth 5~ 6 cm, put one seed potato block in each hole, and cover the incision with soil to the side.

4, fertilization: ridge surface removal or spot application, generally every 20 days after the application of seedling fertilizer, according to the actual situation, every month or so fertilizer. Ginger and potato are mainly composed of phosphorus and potassium fertilizer and multi-element fertilizer. In the early stage, fertilizer is applied per mu (46% urea about 5 kg + ternary compound fertilizer about 8 kg)/time. Later fertilization (ternary compound fertilizer about 12 kg + urea about 3 kg) per mu/time. Generally, the total amount of fertilizer applied per mu is about 170 kg, including urea about 50 kg, ternary compound fertilizer about 100 kg and potassium sulfate about 20 kg. According to different geological conditions, the amount of fertilization is also different, according to the principle of light fertilization in the early stage and heavy fertilization in the late stage.

5, weeding: 20~25 days after planting artificial or herbicide weeding, herbicide per mu with 74.7% of the farmer Le water-soluble agent 150 grams mixed with 60 kilograms of water spray. Artificial weeding should be used within 10 cm around the seedling to avoid spraying ginger and potato seedlings by mistake. In the middle stage, weeding should be carried out timely according to the actual situation. The whole cycle should generally be weeded 6~8 times.

6. Cultivation: 45~50 days after planting, it should be combined with intertillage and weeding, trench cultivation, and successive cultivation around the plant, and cultivated once every 35~40 days. If it rains, the topsoil can be hardened earlier. Cultivate soil mainly in autumn and early winter, 5~6 times in the whole period.

7. Scaffolding: Pay attention to checking seedlings and supplementing seedlings after emergence. When the seedlings are about 10cm high, thin the seedlings and leave 1~3 buds in each hole. When the seedling height is 15~20cm, erect the frame, select 2~2.5 meters long hard straight bamboo poles or branches, each plant is firmly inserted, and let the vines extend naturally to climb the scaffold.

8. Irrigation: Generally, the first half of the year is rainy season, so drainage measures should be taken. In case of dry heat, water should be poured in the morning, and deep irrigation should not be allowed. The water supply in the early stage shall be dry and wet. July ~ September is sensitive to water, August ~ September autumn drought can be deep irrigation, late irrigation and early drainage. In October,"Zouma Water" was poured to keep moisture and prevent immersion. Stop using water until the beginning of winter to keep the soil dry and loose.

The above is a detailed introduction to the cultivation method and time of ginger potato, I hope to help everyone.
