How to grow potatoes Tall potatoes are planted

Every year, the potato seeds are planted in the shed at the beginning of April, and when the potato seedlings have grown to 2 inches high in early May, they are transplanted to the field, and the potatoes can be harvested half a month earlier at the end of June. Its specific management techniques are as follows:

1. Cut into pieces to promote germination. Germination begins 20 days before sowing in early March. When the potato seeds are diced, each piece has at least one bud eye.

10 15 catties is appropriate. After cutting, sterilize and disinfect the water-soaked seeds with small ash dry mix or carbendazim powder 1:200 times.

After the seed block is dried, the seedbed germination will begin, and there are two methods: one is to use sand to germinate in the corner of the house above 15 at room temperature, and a layer of sand and a layer of seed blocks; The second is to dig a pit in the east and west direction of the outdoor ventilation and sunrise to promote germination, the pit is about 25 cm deep, a layer of sand and a layer of seed blocks, 3 layers are appropriate, and then the arch shed film covers, and the grass curtain is covered at night. The above two methods should be sprinkled with water 1 2 times during germination to prevent drying.

When the buds grow to a long centimeter, sowing begins.

Second, land preparation and ditching. Look at the soil moisture before planting, if the moisture is not good, you can consider irrigation ditch moisture, and the moisture building period should be 7 to 10 days before planting. Potato planting is generally double-furrow planting, and 50 cm in large rows and 40 cm in small rows can be used when ditching.

3. Sowing and covering film. The spring equinox to Qingming is the best period, and it should be particularly mentioned here that detoxified potatoes can be sown early in advance, and the plant spacing can be controlled at 20 cm before the spring equinox.

Before sowing, spray along the ditch with 1:10,000 times water of octaposulfuric acid to prevent underground pests. Organic fertilizer can be sprinkled directly in the ditch or during land preparation; Chemical fertilizers can be placed in ditches or sprinkled between blocks (be careful not to come into direct contact with the blocks).

When sowing, there are two ways to put the seed block into the ditch: one is that the seed buds are facing downward, and the potato roots grown by this method are strong and strong, the potatoes are few but the pieces are large, but the seedlings are 2 3 days late; Another method is to plant buds facing upwards, and the roots of potatoes grown by this method are relatively short, the potatoes are small but numerous, and the seedlings are 2 to 3 days early. After the end of planting, take soil from both sides of the big row, cover the space of the potato ditch and the small row, and add a microfilm cover to compact it.

Fourth, seedling release and seedling management. After Qingming, about 20 days after sowing, there are seedlings exposed to the soil, at this time, the seedlings can be washed to break the microfilm and release the wind to prevent steaming seedlings. When the seedlings grow to 10 cm high, the membrane around the seedlings is pressed tightly with soil to retain water and press the grass.

Potatoes should not be watered in the early stage of growth, and then watered after they see flowers. If there is no rain, you can water every 10 days, generally watering 2 or 3 times to mature, and stop watering 10 days before harvest. Prevent insect pests such as aphids or thrips at the seedling stage.

Fifth, reasonable fertilization. Potatoes like to apply farmhouse fertilizer, 4000 5000 catties per square meter is appropriate, and at the same time, nitrogen, phosphorus, and potassium should be used together when applying chemical fertilizer. Potatoes have a large demand for potassium, and the scientific and reasonable ratio of nitrogen, phosphorus and potassium fertilizer is:

1：。Potatoes like to absorb ammonium nitrogen and absorb more sulfur. According to experiments, for every 1 kg of potassium sulfate fertilizer, the yield of potatoes can be increased by 100 150 kg.

Potatoes are grown as follows:

1.Potatoes should not be cropped continuously, and in order to ensure their growth, yield and quality, they should be cultivated in areas that have not been sown within 2 to 3 years. In addition, it should be cultivated on loose, fertile sandy soil with high organic matter content, which is conducive to the growth and growth of potato chips and can promote later production.

In addition, potatoes are afraid of water, so choose fields with higher ground and better irrigation methods.

2.Once the potatoes are processed, they can be planted by digging a shallow gully in the ground and cutting the potatoes into 15 centimeters. There is no need for watering after planting, and there is no need for fertilization, if you want to fertilize, you can use some potassium fertilizer appropriately, avoid using urea and animal manure so as not to affect the taste.

3.In the cultivation process of potatoes, the occurrence of diseases will lead to the reduction of yield and affect the quality of potatoes, above-ground insect pests such as aphids and cabbage insects, which can be controlled with high-efficiency imidacloprid solution, and underground pests such as ground tiger and needleworm can be controlled by spraying trichlorfon powder during the potato growth period.

4.After sowing, irrigate in time when the weather is dry, keep the soil in a moist state, ensure the emergence of seedlings, the germination period, the budding period and the full flowering period are the key periods, appropriately increase the amount of watering, ensure that the soil water is sufficient, and the demand for water will increase when the stems and leaves stop growing, so as not to late ripening of potatoes or reduce the yield.

How to grow potatoes in 2011.

1. Soil preparation and fertilization, should choose fertile soil, deep soil layer, loose, good air permeability, slightly acidic sandy loam soil, stubble extermination, deep ploughing, ploughing depth should reach 20 cm. Combined with the application of 2000 kg of well-rotted organic fertilizer per mu, and at the same time according to the soil moisture into more than 20 kg of compound fertilizer (the ratio of nitrogen, phosphorus and potassium is: 2).

2. Seed potato treatment, select suitable excellent varieties, and should carry out germination treatment, the seed potato can be dried under scattered light, keep 15-20, and directly promote the short strong buds, and sow seeds; Before sowing, plant ash and chlorothalonil should be added to the new high-fat film for seed dressing, so as to promote the healing of the knife edge of the cut as soon as possible, reduce seed rot, increase potassium, and prevent diseases.

3. Reasonable dense planting, timely sowing, and spraying new high-fat film on the surface in time after planting to prevent soil slab and improve the seedling emergence rate. After the emergence of seedlings, the soil should be cultivated in time, and the weeding and loosening of the soil should be the mainstay, and a small amount of soil should be cultivated to the seedling roots. At the same time, it is combined with spraying of new high-lipid film to prevent bacterial infection, improve the ability to resist natural disasters, improve the intensity of photosynthesis, and protect the growth of seedlings.

4. Field management, should be timely loosening, soil ridge formation, timely watering, weeding, reasonable fertilization, at the same time should be before potato flowering, tuber formation period and expansion period timely spraying of the fruit strong Tiling, in order to effectively control the wild growth of branches and leaves on the surface, accelerate the ultra-rapid expansion of underground tubers, enhance the ability to resist insect pests, and ensure the high quality, efficiency and harvest of potatoes.

5. To prevent and control pests and diseases, apply 3-4 bottles of phosphine at the time of sowing or before tubing, remove underground pests, and cooperate with the spraying of new high-fat film to improve the efficacy; At the same time, for aphids, 28-star ladybugs, early blight, late blight and other pests and diseases, they can be sprayed according to the requirements of plant protection to kill the pesticides, and at the same time, the new high-fat film is sprayed 800 times to consolidate the effect.

Here's how:1. Cut into pieces to promote germination. 20 days before preparing to sow potatoes, that is, at the beginning of March every year, we have to start germination, and each seed is cut with at least one bud eye, and then use small ash dry mix or carbendazim powder to 1:

200 times sterilization and disinfection of water-soaked seeds.

2. At room temperature above 15, use sand in the corner of the house to promote germination, a layer of sand and a layer of seed blocks.

3. In the outdoor ventilation and chaoyang, dig a pit in the east-west direction to promote germination, the pit is about 25cm deep, a layer of sand and a layer of seed blocks, it is advisable to put 3 layers, and then add arch shed film cover, and cover the straw curtain at night to keep warm.

4. Prepare the land and open the ditch. Before planting must look at the soil moisture, if the moisture is not good, it is necessary to consider irrigation ditch moisture, the best time to make moisture during the planting period is about 7-10 days before planting, potato planting is generally double ditch planting, ditching can be used large row 50 cm, small row 40 cm.

1.When choosing a bean seed, use potatoes that weigh about 60-80 grams and were planted the year before as seeds, and generally choose healthy and intact potatoes with more sprouts on them. 2.

Plough the land, apply an appropriate amount of manure before turning the soil, and then plough, the depth of ploughing is to cut the pieces to promote germination, use a sterilized knife to cut the potatoes into 3-4 pieces, each small piece should have small buds on it, and then sterilize the wound on the small piece of potatoes, and finally dry it to sow seeds. 4.Plant the mulch, sow the processed potato pieces into the ploughed soil, and pay attention to the sprout eyes of the potatoes facing upwards so that they can sprout and grow better.

Then cover with a thin layer of soil, and then cover it with a layer of mulch film after the thin soil is leveled, so that the potatoes can grow in a warm and moisturizing environment. 5.In the later stage of maintenance, after the potato planting is completed, it should be watered once permeable, and suitable temperature and light conditions should be provided for it, and the potatoes will grow seedlings in about 7-10 days.

After the potatoes have grown seedlings, apply thin manure to speed up their growth. Do a good job of weeding after 1 month to prevent weeds from absorbing too much nutrients. [Bixin] [Bixin].

The way to grow potatoes is to choose the right soil and handle the potatoes well.

Potatoes are native to the Andes Mountains of South America, and their cultivation can be traced back to the southern region of Peru from 8,000 to 5,000 BC. In the mid-16th century, potatoes were brought to Europe from South America by a Spanish colonist. At that time, people always admired the beauty of its flowers and used it as an ornament.

Northeast China and Hebei are called potatoes, North China is called yam eggs, northwest and two lakes are called artichoke, and Jiangsu and Zhejiang are called artichoke or yangshan potato. Guangdong is called the potato, and the eastern part of Guangdong is called the Dutch potato. In eastern Fujian, it is called sweet potato, and in northwest Hubei it is called potato.

Tips for buying potatoes

If there is no broken skin, try to choose a round one, and the rounder the better. The skin must be dry, without blisters, otherwise the storage time will be short, and the taste will not be good. Don't have buds and greens, that's pretty much it.

Potatoes that have sprouted sprouts contain toxins and should not be eaten. If you notice that the skin of the potatoes is green, do not eat even a very light green color. Because the green color of potatoes is a sign of the presence of toxic alkaloids, they can be poisoned if eaten.

Inferior potato chunks are small and uneven; There are lesions or moth-eaten holes; The tubers wilt and soften, and the tubers sprout or turn green; mixed with more insect pests and crippled potato pieces; There can be no small buds on the potatoes with a rotten smell, otherwise it will have a great impact, and there is no color to see if it is fresh, and there should be no black bruises. Most of the inside is bad, of course, ** is also one thing, the real thing is the best.
