How to grow foot potatoes

Foot potatoes can not only be eaten, but also can make sugar, wine and alcohol. It is a kind of plant that many farmers will grow, and it is now loved by many people who are in good health. So how to grow foot potatoes?

I. Land preparation

Because of the long growing period, large tuber roots and deep soil, the planting land requires deep ploughing and deep ploughing in winter. After the topsoil is dry, 2500-4000 kg of rotten organic fertilizer is applied per mu, and the rake is evenly turned into a 1.2m (including trench) wide high border.

2. Planting

From mid-late April to early May, two 8 cm planting ditches were opened in each row, then lime was sprinkled in each row to control underground pests, and the seed potatoes were arranged according to the plant spacing of 33-40 cm. Pay attention to the potato pieces facing down and the skin facing east (in the direction of sunrise), and then ridging with soil covering, the ridge height is about 10 cm, and the seedlings are planted slowly without accelerating germination, but the roots sprout after the roots and the roots are well developed. Grow strong.

III. Field management

1. Set up the frame to draw the vine, fix the seedling and remove the bud. When the seedlings grow to 25-30 cm, use 2-meter-long small miscellaneous wood straight into an independent frame or small mangosteen into a herringbone frame to support the stem vine on the shelf. Only one strong seedling was left in each plant, and all the rest were removed. If the stem vine grows too much and produces too many axillary buds, it should be removed. In July, the zero seed buds growing in the leaf axils should be erased in time in order to reduce nutrient consumption and facilitate tuber hypertrophy, except for keeping robust seeds.

two。 Ploughing and cultivating soil. There are many potato roots on the feet, and most of them are distributed on the surface. in order to avoid root damage, it is only necessary to plough once in the seedling stage and sprinkle Camellia oleifera shell between the leaves. Camellia oleifera shell is a good fertilizer, as well as grass control, soil loosening and insect control. When the stem vine grows to about 1.2 meters, cultivate the soil once with fertilization, and then cover the whole border with thatch, which can not only prevent weeds from growing and no-tillage, but also adjust temperature and humidity.

3.。 Fertilizer and water management. During the growth period, topdressing was applied for 3-4 times. Seedling fertilizer: combined with mid-tillage, dig 6-10 cm fertilizer ditch between rows, apply 5-10 kg urea per mu, cover soil and cover Camellia oleifera shell. Strong seedling fertilizer: combined with soil cultivation, 10-20 kg calcium magnesium phosphate fertilizer and appropriate amount of plant ash and soil fertilizer were applied per mu, heavy fertilizer was applied once at flower bud stage and middle stage of tuber expansion, and human urine was applied 500-1000 kg per mu. Human urine plays a significant role in promoting the expansion of tuber and plays a key role in the formation of yield. Topdressing is forbidden to apply human dung and pig, cattle dung, because manure is easy to cause stem vines, tuber skin blackening, leading to disease. Foot potato is more drought-resistant, water requirements are not strict, in July-August drought, appropriate watering 1-2 times.

IV. Pest control

Foot potato diseases and insect pests are less, a small amount of planting is generally rarely used drugs, when planting is mainly agricultural control, chemicals as the shop, mainly select some high-efficiency, low-toxicity and low-residue pesticides. The main diseases are anthracnose and rust, which can be controlled by carbendazim, thiophanate, trimethoprim and so on. Pests include sawleaf wasps, ground tigers, grubs and other underground pests, which can be controlled by root irrigation with 800 times liquid of trichlorfon. No medicine is usually used one month before harvest.

Foot potatoes can generally be harvested from October to November, and can be stored for a long time after harvest, and they are very nutritious and are very good healthy food.
