How to make potatoes high-yield? Potato efficient planting technology

When planting potatoes, we all hope that the higher the potato, the better. The following Hui Nong network Xiaobian will share with you the efficient planting technology of potatoes, I hope to help you.

First, the choice of seed potatoes.

According to the actual situation in the locality, the seed potato should use high-quality, high-yield and strong-resistance seed potatoes: strictly select the seed potatoes, eliminate the potato-shaped irregularities, rough skin aging and buds, and dark skin color and other undesirable traits. .

Second, land preparation and fertilization.

Choose loam or sandy loam soil that is loose, fertile, and convenient for irrigation and drainage. The depth of ploughing in spring is 20-30 cm, and it is fine and smooth. At any time, it can be used to make high-quality, decomposed organic fertilizer 5-8 square meters per mu, and potato special compound fertilizer 50- 70 kg. In order to prevent underground pests such as cockroaches and ground tigers, the amount of insecticides such as phoxim poisonous soil or worms is used as indicated.

Third, the seed potato treatment.

In order to make the potatoes emerge quickly, the emergence of the seedlings and the early termination of the potato dormancy period, 20-30 days before sowing, need to be pre-sow treatment.

1. Cut: In order to break the advantage of the top of the potato and save the amount of seed potatoes, the seed potato should be cut into pieces. Before cutting, the cutter is disinfected with 3% water or 75% alcohol. After cutting, in order to prevent the spread of late blight, early blight and ring rot, the potato chips are soaked for 10 minutes with 70% thiophanate-methyl WP or 50% carbendazim WP 500 times. Cut into cubes, each potato has at least two buds and weighs about 25 grams. Cut the block should try to bring the top buds, so that the budding is neat, the smaller seed potatoes (50-100 grams) can be cut 2-4 pieces from the top, the large seed potatoes are first cut from the potato tail, cut to a certain size and then The top slit is 4-5 pieces. If the diseased potato is cut, the knife should be disinfected immediately with 75% alcohol and then cut.

2, warm seed germination: After the potato block incision to dry and heal, placed under 20 ° C humid conditions to germination, the method is: the discharge of the potato block covered with 3-4 cm of wet sand, temperature 15-18 ° C, When the buds grow to 2-3 cm in about 10 days, the fine sand is removed, maintained at 12-15 ° C, and the buds are spread under scattered light conditions, and the seeds are sun-baked for 5-7 days.

Fourth, elective sowing

When planting, the temperature of 10 cm is stable and rises to 5-7 °C, and the temperature can be planted at 12-15 °C for five days. Under the right conditions, the sowing date can increase production by 10%-20% every 5 days in advance. Therefore, the sowing date should not be late.

V. Field management

(1) Management of seedling stage: After the potato is germinated, the “ten” character will be placed in the seedling film at the same time, and the hole will be sealed with soil. Seedlings in the early stage of growth (6-8 leaves), in order to promote the roots of the tree, should be sprayed 2-3 times per mu plus multi-country potato special foliar fertilizer 30-60 grams of water 15 kg. (Before the group) Mu Chong applied 5-10 kg of multi-element balance fertilizer.

(2) Management of the hair growth period: the group is flowering, the soil is not watered, and it needs to be placed before or after the fruiting. Otherwise it will cause the plant to grow. At the end of the flowering period, the application of multi-country potato special foliar fertilizer 30 grams of water to 15 kg, 7-10 days, even spray twice

(3) Management of potato production: The potato-forming period is the main expansion period of the roots. The amount of water and fertilizer needed is large. It should be supplemented 1-2 times in a multi-state, plus a large amount of high-potassium fertilizer, 5-10 kg, and the soil should be kept moist.

Sixth, pest control

(1) Early blight: The main symptoms are dark brown, round or irregular shape of the leaf, with concentric pattern, the outer edge of the lesion is yellow halo, and when the humidity is high, the black mold layer is formed on the lesion. Control method: Before the onset, start spraying 75% chlorothalonil WP 600 times liquid or 77% can kill WP 1500 times, once every 7-10 days, even 2-3 times. Special drugs for Jiaduo disease can be used.

(2) Bacterial wilt: The main symptoms are plant atrophy, light green or pale green, and the lower leaves are all drooping after atrophy. They begin to recover sooner or later. After 4-5 days, all the stems and leaves are wilting and die, but they remain green and the leaves are not withered.蔫, the veins are browned, the stems appear brown stripes, the cut vascular bundles become brown, and when the humidity is high, the cut surface is overflowed by the bacterial liquid. Control method: In the early stage of the disease, the root can be irrigated with 2000 times of 2,000 times of wettable powder. Each plant is filled with 0.3-0.5 liters, once every 7-10 days, and even 2-3 times.

(3) Aphids: 10% imidacloprid wettable powder 1500 times solution, spray control.

(4) Ladybug: The larva can be sprayed with 2.5% cypermethrin emulsifiable concentrate 3000 times or Kungfu emulsifiable concentrate 4000 times.

Note: When the disease prevention and treatment of insects, respectively, add more than 20% of the potato amino acid foliar fertilizer, 30-60 grams of water and 15 kg of water for spraying.

Managed in this way, the potato seedlings are strong, the seedlings are strong, the disease resistance is strong, the fruit is large, the quality is good, and the yield is high. The normal annual yield is increased by 20%-30%.

Seven, harvest

When most of the stems and leaves of the vegetable plant turn from green to yellow, the tubers are harvested when they stop expanding. Avoid damage to potato chips during harvest.
