Why are potatoes seedling, and the detailed method of seedling

Flowers sown in the open field are generally seeded twice. For the first time, after the seedlings are ready, 2-3 seedlings are left in each pier, and the excess is removed according to a certain plant row spacing; The second seedling is also called the fixed seedling, when the seedling grows to 3-4 true leaves, in addition to the grass and flowers that are prepared to be planted in clusters, generally leave a strong seedling, the flower seedlings under the middle can be planted to make up for the lack of plants, for some transplantable flowers, can also be planted to other nurseries.

After thinning, it should be watered in time to prevent the seedlings from being loosened during the seedling thinning process. Seedlings refer to the elimination of unwanted crop seedlings, mainly the elimination of unwanted seedlings. Seedling thinning and seedling setting are two aspects of the same operation.

Seedling: refers to leaving the needed crop seedlings, mainly seedlings.

In the planting process, the seedlings are to be able to better leave high-quality seedlings and improve the overall quality from the foundation.

Seedlings are also known as sparse seedlings. The seedlings should be carried out in a timely manner, with the principle of keeping even, retaining, retaining good, and removing inferiority. Weeding between plants is often carried out at the same time as seedlings to avoid weeds competing for nutrients.

After each seedling, it is best to combine fertilization or watering to promote the healthy growth of seedlings. The last thinning carried out at the seedling stage is also called seedling fixing, and robust seedlings must be selected and retained according to the predetermined planting density and plant row spacing in a timely manner.

Of course, the seedlings and potatoes should be planted in Longqi.

The line spacing should be 50-60

Plant spacing should be 30-40

I believe everyone likes to eat food made of potatoes, fried shredded potatoes, French fries, hash browns, etc. So do you know that potato seedlings need to be pruned during potato growth?

The first thing to understand is that if the leaves of a potato are cut off, it can still survive. The leaves of a potato can be cut alive because it has leaf buds under the leaf axils, and after cutting, new leaves can germinate. The germination of new leaves consumes a lot of nutrients, resulting in excessive dispersion of nutrients, affecting the growth of potato tubers, making potatoes smaller and not fuller, resulting in low yields.

If potato seedlings grow too vigorously, then proper pruning is required. How? Just prune some bushy leaves. Don't trim too much. If you prune too much, the plant will not be able to photosynthesize to make enough organic matter.

1.Pruning: Pruning is required when potato seedlings grow too tall.

In order to reduce the consumption of nutrients, it is necessary to pinch off the overgrown parts, which can promote the growth of side branches and the growth of underground tubers. They cannot grow at will. Otherwise, the nutrients** in the above-ground parts will grow wildly and the underground tubers will be affected.

Seriously affect the income of the farmer's uncle!

2.Pharmacological control: It can also be controlled by medication to avoid overgrowth of potato seedlings. It can be controlled by spraying growth regulators such as paclobutrazol and diluted paclobutrazol once every seven days, twice in a row.

3.Adjust maintenance: adjust maintenance methods, reduce the amount of nitrogen fertilizer, and apply fertilizer reasonably to ensure the balance of various nutrients. Watering should also be controlled to avoid stagnant water. The temperature should not be excessively high and kept within the appropriate range.

4.When pests and diseases occur in potatoes, the leaves should be cut off and the cause should be found according to the symptoms of pests and diseases. Whole-plant spraying of related drugs can achieve the best effect, ensure the recovery and growth of potatoes after pests and diseases, and reduce the death of potatoes after pests and diseases.

In addition, it also needs to be watered properly. In general, watering every 3-4 days is sufficient. The number of watering does not need to be too frequent.

Potato seedlings do not need to be pruned. As long as you water and fertilize regularly, potato seedlings will affect the yield of potatoes if they are pruned.

I think pruning is needed because it increases the yield of the potatoes and it also makes the potatoes grow better, and it also prevents pests and diseases, so I think pruning is needed.

Yes, because in this way the intake of nutrients can be guaranteed, the yield and quality of the crop will not be affected, and the harvest can be improved later.

There is no need to prune, the potato seedlings themselves are not long, and the leaves are the parts that absorb nutrients, and after pruning, it will affect the reproductive growth later. And it also has a certain protective effect on the fruit.

1. Temperature: 15 to 25 degrees is the most suitable for leaf growth, but the suitable temperature for tuber growth is between 16 and 18 degrees. Due to its high temperature requirements, if it does not provide a suitable temperature, it will seriously affect its growth.

If it is above 25 degrees, its tubers will stop growing.

2. Light: Potatoes are more afraid of strong light, and in the growth period, appropriate light time is necessary, otherwise the quality of its fruit will be affected, and the taste is not good. Bright light must be avoided, otherwise the leaves may dry out.

3. Watering: Potatoes like moisture, and a moist soil environment needs to be provided during the growth period. However, when it is rainy in summer, it is necessary to drain the stagnant water in the ground in time, otherwise it will harm the root system.

4. Fertilization: fertilizer plays a relatively large role in the growth of potatoes, and can effectively improve the yield. The base fertilizer is very important, and then the top dressing is mainly the water-soluble fertilizer of fertile leaves.

During the growth of potatoes, potato seedlings do not need to be pruned, because the leaves on the potato seedlings play a photosynthetic role and produce the main organ of photosynthetic matter, which should be protected.

1. Soak seeds with gibberellin and carbendazim, and when sowing, the potatoes are in a dormant state. In order for the beans to take root and germinate as soon as possible, it is necessary to break the dormancy period and germinate quickly. First cut the * bean seed block, put it in milliliters of gibberellin solution, add 10 grams of 50% carbendazim powder, prepare an appropriate amount of solution according to the number of potato seeds, soak for 10 15 minutes, remove and drain, add grass ash and stir evenly to be sown.

2. Soak the seeds with gibberellin and prochloraz, add 1 2 ml of 25% prochloraz to prepare the solution according to milligrams of gibberellin solution, soak the seeds for 10 15 minutes and then pick it up, stir it evenly with plant ash and wait for sowing. 3. Compound seed dressing with a variety of agents. The specific operation is that for every 300 catties of potato seeds, 100 grams of methyl tobuzin, 14 grams of agricultural streptomycin, 5 ml of sodium nitrate, and 25 catties of water are sprayed, which is required to be uniform.

Then use 10 20 pounds of plant ash and mix well.

The way to dress seeds is to cut the potatoes into large pieces, then add some talcum powder and a medicine, mix them well, and then stir well.

We should use some potions, and we should turn the seeds with a hoe, so that we can increase the material of the soil, and it is also a particularly easy way.

Flowers sown in the open field are generally seeded twice. For the first time, after the seedlings are ready, 2-3 seedlings are left in each pier, and the excess is removed according to a certain plant row spacing; The second seedling is also called the fixed seedling, when the seedling grows to 3-4 true leaves, in addition to the grass and flowers that are prepared to be planted in clusters, generally leave a strong seedling, the flower seedlings under the middle can be planted to make up for the lack of plants, for some transplantable flowers, can also be planted to other nurseries.

After thinning, it should be watered in time to prevent the seedlings from being loosened during the seedling thinning process. Seedlings refer to the elimination of unwanted crop seedlings, and the main limb early acre is to remove unwanted seedlings. Seedling thinning and seedling setting are two aspects of the same operation.

Seedling: refers to leaving the needed crop seedlings, mainly seedlings.

When sowing in spring, it is advisable to choose a suitable seed dressing agent for potato seed dressing to prevent and control the occurrence of soil-borne diseases, improve the quality of seed potatoes, prevent seed potato pieces from rotting, and ensure that the seedlings are full, complete and strong, so as to lay the foundation for high yield and good commerciality of potatoes. <>

There are several reasons why potatoes should be dressed before sowing:

First of all, potato seed potatoes are also easily infected by viruses or germs during loading, unloading, transportation and storage, and if not treated, it will cause cross-infection, rot and deterioration, and the seeds will rot when planted in the ground, and the bacteria will infect the plants and cause diseases.

Secondly, when cutting the seed potato into pieces, the cutter is not completely sterilized, which will cause the germs to be transmitted to other healthy seed blocks through the cutter. In addition, due to the trauma caused to the potatoes when cutting, the wounds are easy to breed germs in a humid environment, making the seeds sick. <>

Finally, there are soil-borne disease bacteria in the soil, and if the seeds are not treated well, they are easily infected with the bacteria in the soil when planted in the ground, so that the plants are sick. Therefore, seed dressing can not only effectively reduce bacterial infection, but more importantly, promote seedling emergence, make the seedlings neat and robust, and significantly improve the commodity value and yield of potatoes. Therefore, doing a good job of seed dressing before sowing is to lay a solid foundation for ensuring potato quality and yield.

The types of potato seed dressing are mainly used as agents to prevent and control potato seedling diseases, soil-borne diseases and other problems, such as methyl trop, methyl frost, fludioxonil, azoxystrobin, etc. However, for the perennial problems encountered in potatoes, seed dressing can be carried out in a targeted manner, such as soil-borne diseases are more serious, such as black mole disease, wilt, can be dressed with thioflochloramine, etherstrobin, methyl tropia and other agents, such as late blight, can be used to enoyl manganese zinc, methyl frost manganese zinc, propylene manganese zinc and other agents for seed dressing, such as underground pests are more serious, can be used imidacloprid, thiamethoxam, clothianidin and other agents to dress seeds, and at the same time can also control aphids, planthoppers, thrips and other insect pests at the seedling stage; The general formula can be used methyl tray + downy mildew + streptomycin, etc., and the prevention and control are relatively large.

Now the quality of seed potatoes is uneven, and the soil pollution is serious, therefore, the seed dressing can not be sloppy, and the seed dressing must be done before planting, which is also an important link to ensure increased production and income.

With the expansion of potato planting area, heavy cropping is serious, with as little as 1 year and as much as 2-3 years, which leads to the unreasonable structure of soil microbial population and the obstacle of continuous cropping. In addition, continuous cropping has aggravated soil-borne diseases such as mole, dry rot and black shin disease, resulting in reduced crop yields. In addition, seed potatoes are easy to be infected with germs during transportation and storage, and artificially bring trauma to potatoes when sowing and cutting, and their wounds are moist and easy to be infected with miscellaneous bacteria. Therefore, when sowing in spring, it is advisable to choose a suitable seed dressing agent for potato seed dressing to prevent and control the occurrence of soil-borne diseases, improve the quality of seed potatoes, prevent seed potato pieces from rotting, and ensure that the seedlings are complete, the seedlings are complete, and the seedlings are strong, so as to lay the foundation for high yield and good commerciality of potatoes.

Because seed potatoes are easily infected by viruses or germs during loading, unloading, transportation and storage, if not treated, it will cause cross-infection, rot and deterioration, and the seeds will rot when planted in the ground, and the bacteria will infect the plants and cause diseases.

This is conducive to the absorption of water, the nutrient absorption of potato seeds, and the fruit of potatoes can grow large and lush.

1. It is very important to choose potato seeds, be sure to choose potatoes that are full and have a smooth and round skin to make seeds. And cut the seeds are juicy inside, and a potato can be cut into three or four seeds. Each seed should have a seed bud on it.

In this way, the potatoes can grow vigorously, and the seeds of the potatoes can be dried in the sun for a day, and then they can be planted in the old chain. Never use wilted or rotten potatoes as seeds. This will affect the harvest of the year.

2. To plant all the cut potatoes in the sorted soil, basically 1 to 2 potato seeds should be placed in a nest. The dug nest is basically 10 cm deep and then covered with soil. Basically, the spacing should be kept at 30 cm, the plant spacing should be kept at 20 cm, and if the weather is cold when planting, you can cover the plastic foam to increase the temperature.

Basically, the temperature at which potatoes grow is about 20 degrees, and the potato seedlings should have enough light, so that the potato seedlings will grow vigorously. Basically, there are potatoes grown in greenhouses, such as potatoes grown in greenhouses, as long as the temperature and light are suitable for potato growth, it is very easy to manage, at least diseases and insect pests will be reduced.

<> after the emergence of potato seedlings, generally 1 seed block can leave 1-2 seedlings, to ensure that the seedlings have enough growth space to grow, when the seedlings need to be seedlings and seedlings after the seedlings, and combined with weeding for the first time in the cultivating, the depth is generally 8-10cm, 10-15 days later combined with the soil for the second tour of the macro dry tillage, the thickness of the soil should not exceed 10cm. It should be noted that if the potatoes enter the seedling stage in early summer, it is also necessary to pay attention to ventilation and control the temperature in the shed.

1. Leave one potato seedling or a bunch of seedlings

1. The number of seedlings retained.

When the potatoes emerge, generally 1-2 seedlings can be kept on 1 seed block, and the other seedlings can be pulled out to ensure that the seedlings have enough space to grow and the area of the nutrient cave can be grown.

2. How to manage after emergence.

1) Seedlings and seedlings: after the seedlings need to be checked in time, seedlings, and seedlings should be erected, and the seedlings should be weak and strong, so as to ensure the variety of the plant and ensure the yield.

2) cultivating soil: the first cultivation after the seedlings, the depth is generally 8-10cm and combined with weeding, 10-15 days after the first cultivation and then the second cultivation, but also need to carry out soil cultivation, soil thickness should not exceed 10cm.

3) Timely top dressing: After the emergence of seedlings, it is necessary to apply sprout fertilizer, and generally apply clean manure water and a small amount of nitrogen fertilizer to promote the growth of seedlings as soon as possible.

4) Ventilation: Under normal circumstances, potatoes should be in early summer when they enter the seedling stage, and the temperature at this time is rising, so the potatoes planted in greenhouses need to be ventilated. At about 9 a.m. every day, when the temperature is above 16, open the vent for ventilation to avoid the temperature in the shed from exceeding 25.

Second, the potato seedlings grow too tall to deal with the treatment

1. When the potato seedlings grow too tall, you can spray an appropriate amount of paclobutrazol to control the growth, generally spraying once every 7 days, and spraying 2 times in a row.

2. If too much nitrogen fertilizer is applied, but no phosphorus and potassium fertilizer is applied, it will also cause the plant to grow, so it is necessary to stop the application of nitrogen fertilizer after this problem, and appropriately apply some fertilizers containing phosphorus, potassium, magnesium and other nutrients, the frequency of application is generally not too high, and it is advisable to apply it once every 10-15 days.

3. The phenomenon of overgrowth can also be solved by controlling water, and the water should be controlled when the potato seedlings grow too tall, until the seedlings appear in drought, and then water an appropriate amount of water. Usually the potato seedlings are not watered before they see flowers, and when the potato seedlings see flowers, they can be watered once every 10 days in the case of drought and no rain.
