What should I do if the potato seedlings grow too tall? How tall are potato seedlings generally not

1. Pinch the tip and prune:When the potato seedlings grow too high, they need to be pruned with the tips and cannot be allowed to grow, or the aboveground part will be fed with nutrients, and the underground tubers will be affected. It is necessary to pinch off the part that grows too high to reduce the consumption of nutrients, which can promote the growth of side branches and also facilitate the growth of underground tubers.

2. Drug control:It can also be controlled by drugs to avoid excessive growth of potato seedlings, and paclobutrazol can be sprayed.

Oxybutramol and other growth regulators are controlled, sprayed once every seven days or so, and can be controlled by spraying twice in a row.

3. Adjust maintenance:It is also necessary to adjust the maintenance method, reduce the application of nitrogen fertilizer, and apply fertilizer reasonably to ensure the balance of various nutrients. It is also necessary to control watering to avoid water accumulation.

The temperature should not be too high and keep it within the appropriate range.

The reason for the longevity

1. High planting density: the potato seedlings grow long, which may be due to the large planting density, the large number of plants, the mutual shading between branches and leaves, and the affected lighting, which will lead to the growth of potato seedlings.

2. Overwatering: If you water too much, it will be supplied to the stems and leaves in large quantities, causing the potato seedlings to grow wildly and cause them to grow.

3. Improper fertilization: too much fertilization or too much nitrogen fertilizer will cause growth.

Breed classification

Colored potatoes include purple, red, black, yellow potatoes, colorful potatoes, etc. China has cultivated high-quality colored potatoes mainly purple and red, and cross-crossed old purple and red potato varieties with excellent high-yield potato varieties to improve and screen more than 100 varieties of colored potatoes.

Compared with the old varieties, the improved colored potato sprouts have small eyes, good appearance, strong disease resistance, and the yield per mu can reach 1000 to 1500 kg. Colored potatoes can also be developed as a specialty food. Because it contains antioxidants, it is colored potato chips after being fried at high temperatures.

It still retains its natural color. In addition, purple potatoes are not sensitive to light, and fried potato chips retain their original color for a long time.

The black-purple color of black potatoes is due to the high amount of anthocyanins.

Whereas, anthocyanins have anti-aging effects. At the same time, it also has the characteristics of developed main stalks, few branches, strong growth potential and strong disease resistance, with a yield of 1500 kg per mu, which is about 20% higher than that of ordinary potato varieties. At the same time, due to the improvement of disease resistance of this variety, the dosage of pesticides is greatly reduced in production, which is conducive to the production of pollution-free and pollution-free green food.

If the potato seedlings grow too tall, they must be topped, that is, the tips must be pinched.

There are two main periods of potato topping and forking, one is the period when potatoes are about to bloom after budding, at this time, you can top early to remove the flower buds to avoid moss flowering and affecting nutrient accumulation, which can promote the development and maturity of potatoes.

Another is in the period when potatoes appear for a long time, and you can also control the prosperity by topping, and promote the growth of the later stage through this measure. In addition to the above two cases, potatoes generally do not need to be topped and crossed in other periods.

Maintenance method. 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 organic fertilizer.

If the potato seedlings grow too tall, they must be topped, that is, they must be pinched off, because the potatoes are divided into two parts: above-ground stems and underground stems, and if the above-ground part grows crazy, it will affect the growth of underground tubers.

You can pluck the top, the potatoes should not be watered too much, and they should be exposed to more sunlight.

If you cut the potatoes, you will still grow them.

Potato seedlings are generally no more than two meters. The height of potato seedlings is not absolute, generally needs to be controlled within 50 centimeters, if the planting soil is fertile and the nutrients are sufficient, the potato seedlings can grow to a height of one to two meters. In the daily management of potato seedlings, we should pay attention to pinching the tip, the time of pinching the tip is selected after the potato blooms or grows buds, and the plant height of the potato seedling is controlled at about 40 cm after pinching the tip, and the potato pinching tip can reduce nutrient consumption and is more conducive to the growth of tubers.

Potato straw pinching time

The pinching of the wild beans is to hit the top, and after pinching the tip, it will bear more fruit and increase the yield. Potatoes are generally pinched after flowering, and the pinching is mainly to remove the buds and moss of the plant, so as to save nutrients for the plant, so that the potatoes have sufficient nutrients and can grow and develop normally. When pinching potatoes, there is no need to pluck the branches, which will affect the growth of the plant.

After the potatoes bloom during the summer, they need to be topped with the tips of the plants, which mainly removes the buds and moss of the plants. After removing the flower buds and moss, you can avoid a large amount of nutrient consumption of the plant and save nutrients. The nutrients of the plant are sufficient, which is conducive to the growth and development of potatoes, can make potatoes abundant, and can ensure the quality of potatoes.

After the potatoes are topped, an appropriate amount of carbendazim solution can be applied to the wound site of the plant, which has the effect of sterilization and disinfection. Potatoes are an annual herbaceous plant of the Solanaceae family, and the plants can be sown in multiple seasons, sown between February and March in spring, and harvested between May and June. Autumn is sown between October and December and can be harvested between January and March of the following year.

Cut off the tips of the orange field, and cut off the excess branches and leaves when the potato seedlings are too high; drug prevention and control, the use of paclobutrazol and uniconazole growth regulators to inhibit the growth of seedlings; Moderate fertilization, watering every 10 days, spraying potassium dihydrogen phosphate on the flowers and leaves after the stems have grown; Light management, to ensure more than 7 hours of light every day, when the light is strong, build a shade net in time to block strong light.

1. Trim and sharpen.

When the potato seedlings are too high, the seedlings should be pruned and pointed out in time, so that they can not grow freely, and the nutrients will be taken away by the transported seedlings, which will affect the growth of the underground potato tubers. The branches and leaves that grow too tall of potato seedlings are cut off to reduce nutrient consumption and promote the growth of side branches of seedlings.

2. Drug prevention and treatment.

In addition to physical pruning to remove the tip, drugs can be used to control and prevent the potato seedlings from growing too tall. The growth of paclobutrazol and uniconazole growth regulators was used to inhibit the growth of seedlings, and the pesticides were sprayed about once every 7 days. Generally, it can be controlled by spraying twice.

3. Moderate fertilizer and water.

Too much watering, a large amount of water is supplied to the stems and leaves of potato seedlings, which will cause the stems and leaves to grow wildly. Pay attention to reasonable fertilization, after the potato stems grow, you can spray potassium dihydrogen phosphate on the flowers and leaves to reduce the number of nitrogen fertilizers, in high temperature weather, watering once every 10 days, after heavy rain, timely drainage, to avoid water rot roots.

4. Light treatment.

When maintaining potato seedlings, it is necessary to ensure more than 7 hours of light time a day to promote the photosynthesis of plants and prevent the phenomenon of only growing seedlings. When the light is strong in summer, build a shade net in time to block the strong light and promote the growth of the bottom stem.

Summary. 1. Pinch the tip of the pruning: pinch off the part of the potato seedlings that grow too high to reduce nutrient consumption.

2. Spraying growth regulator: spray paclobutrazol on potato seedlings every seven days, and spray twice in a row. 3. Post-management:

In the later maintenance process, the amount of nitrogen fertilizer should be reduced and water control should be strengthened. 4. Precautions: Reasonable dense planting to avoid excessive growth of potatoes.

1. Pinch the tip of the pruning: pinch off the part of the potato seedlings that grow too high in the first mountain to reduce nutrient consumption. 2. Spraying growth regulators:

Spray paclobutrazol on the potato seedlings every seven days, and spray twice in a row. 3. Post-management: In the post-maintenance process, reduce the amount of nitrogen fertilizer applied and strengthen water control.

Xinghui 4. Precautions: Reasonable dense planting to avoid excessive growth of potatoes.

How to deal with the potato seedlings growing too vigorously 1, pinching the tip pruning The potato seedlings are too vigorous, which can be solved by pinching the tip of the pruning, the potato seedlings grow too vigorously, and a large amount of nutrients need to be consumed, which affects the growth of underground tubers, so it is necessary to pinch off the parts that grow too high, reduce nutrient consumption, promote the growth of side branches, and facilitate the growth of underground tubers. 2. Spraying growth regulator potato seedlings can also be controlled by drugs to avoid excessive plant growth and affect tuber growth. 3. In the later stage, the maintenance method should be adjusted to reduce the application of nitrogen fertilizer, and the reasonable fertilization should be applied to ensure the balance of nutrients required by the potatoes.

4. Pay attention to the situation that the potato seedlings are too long, which may be the planting density is too large, the branches and leaves of the plants block each other, and the lighting is affected, which in turn leads to the phenomenon of over-growth of the plants.

The potato seedling is too tall and needs to be taken in time, you can pinch the tip of the prune, pinch off the part that grows too much or taller, promote the growth of side branches, and also facilitate the growth of underground tubers. It can also be controlled by drugs, spraying paclobutrazole, dillobutrazol and other growth regulators, and spraying twice in a row every seven days. You can also adjust the maintenance method to reduce the application of nitrogen fertilizer, control the watering, and the temperature should not be too high.

<> potato seedlings grow too vigorously, they can be improved by pinching the tips appropriately and spraying drugs. The top of the seedlings is removed, and the top of the plant is cut off by hail, so that the nutrients can be supplied to the bottom of the ground, so that the nutrients can be transported to the potato tubers. Spray some anti-growth agents to control, such as adding 100 mg of paclobutrazol spray with one liter of water, and generally use it 2-3 times in a row to have an effect.
