Potatoes are a kind of temperature loving crops, and potatoes will wither their leaves when they gro

Potatoes are potatoes, and potatoes contain a lot of starch, which is also the main energy we eat potatoes. And the protein content is also high, which can promote the growth of the human body.

Leaf blight is the key to damage potato leaves, from the leaves and their edges to dry up gradually in the early stage of disease, and the green-brown spots slowly expand into a large area of light brown dead spots, and the leaves lose green and gradually roll in the middle and late stages, and finally cause a whole leaf to scorch.

Potatoes are yellowed on a large scale, but because it is very similar to the lack of water, many people mistakenly think that it is caused by a lack of water and drought, so they will water the potatoes, but after watering, the disease does not reduce, but becomes more and more serious. Some trees will even wither and die. Diseased potatoes generally start from the lower leaves of the plant or turn yellow, and then gradually develop the trend, the potato plant will turn brown and dry up, and the leaves will dry up but not fall off in the middle and late stages.

When the pathogenic bacteria gradually infect the plants, it is easy to cause the withering of yellow seedlings. The pathogenic bacteria remain in the soil environment, and when the environmental temperature and other standards are achieved, it is easy to infect the plant according to the wounds and root hairs of the plant, causing potato disease and dryness.

Potatoes do not grow with zinc, and the outermost part of the leaves, along with the tips of the leaves, are the main signs of dryness and drying. In the long run, the leaves and stems of potatoes will also die due to fertilization. Lack of fertilizer is also very harmful to the growth of upright stems of potatoes.

Potatoes are grown under conditions of prolonged drought, and the relevant management methods are not usually implemented. According to the needs and thoughts of growers, under long-term dry conditions, irrigation of a large amount of water in the continuous high temperature range at one time will cause the branches of potatoes to wither.

There are many flora added to chemical fertilizers, which can fill a lot of flora for the soil layer, and continue to multiply, inhibit the growth of harmful and beneficial bacteria, maintain potato rhizomes, adjust and improve the natural environment for potato growth, and loosen the quality of the land. Filling the soil layer with a variety of nutrients can support the growth of potatoes and improve their ability to resist work.

Without the potassium fertilizer needed to supplement the potatoes, the leaves above the surface of the potatoes will dry up and shrivel. Fertilization is just one of the causes of potato leaves drying out, factors such as moisture and pests and diseases. This is also the main reason for the yellowing of the leaves of potatoes.

Late blight begins with greenish-brown spots like water stains at the tips or edges of the leaves, with faint green halos around the spots. When the leaves are wet, a white mold layer will also be formed on the spots. After that, the lesions gradually increase, turn brown and wither, and crack brittle when pinched.

Finally, the whole leaf is dried and withered, turning into scorched, if the potato is deficient in potassium during the growth process, in its tuber formation period, there will be symptoms of atrophy of the leaf tip and leaf edge, and gradually yellowing, serious will be scorched and withered, and it will be broken when pinched.

In the process of potato planting, if the potato leaves are withered, it is likely to be affected by the natural environment, and it should be watered in time to replenish the moisture of the root system.

Potato seeds need to have sprouts, when cutting to ensure that each piece of potatoes has germination, some pieces of cutting do not reserve buds on it, then after planting in the soil, the potato is dead, and it can not grow normally. After simmering in the soil for a period of time, this potato cube will naturally rot slowly, because there is more contact with the outside world, bacteria invade, and this is a lifeless potato species. Be sure to pay attention when cutting the pieces and make sure you have them on top of each one.

In the early stages of potato planting, there is a need for water, but it is not possible to do so with too much water, especially when there is water in the soil. After the potato is cut into pieces, the cut surface itself is very fragile and easy to be invaded by bacteria, at this time, too much water in the soil will cause the incision to be eroded by water, making it easier for bacteria to erode the potatoes, until finally the potatoes are successfully rotten by water and rot. Before planting, it is important to know how wet the soil is and how much rain will fall.

In the growth of plants, diseases can be said to be relatively common, some kinds of potatoes do carry pathogens, but they are not in the budding state in the early stage of planting, and they can not be seen, and after planting, the disease develops rapidly, and finally leads to the rot of potato seeds, which is the rot caused by the disease. Therefore, potatoes will basically be disinfected before sowing, but some of the disinfection is not in place or will rot, which is mainly dependent on your own carefulness, which is difficult to avoid.

For seeds, temperature is always a big problem, and many varieties of crops often fail to germinate due to high temperatures, especially on the potato side, and the temperature discomfort can eventually lead to rot. Potatoes are stuffy in the soil, if the temperature is too high, some germs will be very active, seriously affecting the growth of potatoes, you must know that there are not a lot of bacteria in the soil, and the final result is rot.

If there is a sudden problem, it may also be due to the variety, and the potatoes are not treated in advance, which can also lead to rot.

It may be because the cutting area is too large, or it may be that the cutting is not up to standard, or it may be that the soil is too wet.

Potato planting should not be heavy, and the heavy cropping plots not only have more and more serious pests and diseases, but also the yield is getting lower and lower. Therefore, it is advisable to rotate crops and avoid heavy cropping. Potatoes can be rotated with wheat, corn, millet and other crops, and avoid cross-stubble with Solanaceae crops such as eggplant, tomatoes, peppers, etc., which are easy to be infected with diseases.

The plots should not be replaced, first of all, fertilizer should be applied according to the characteristics of potato fertilizer, and secondly, it is necessary to prevent the diseases that may occur when planting heavy crops, and carry out soil improvement.

The soil must be loosened in time, the crop rotation must be reasonable, and then the ventilation and drying must be ensured, the moisture of the soil must be ensured, and then the pests must be removed, and the weeds must be cleaned up in time.

It rains a lot, fertilize it often. Frequent watering, poor soil quality, and too dry soil for planting can all affect the yield of potatoes.

Potatoes are common vegetables in our daily life, because of their rich nutrition by people, potato planting area is also increasing year by year, but potato planting needs for water and fertilizer is very special, how to manage water and fertilizer for potatoes is a headache for vegetable farmers, so, how to water in the whole process of potato planting? What are the precautions when watering? Let's take a look!

When potatoes are planted, if the soil is wet and cold, the moisture is good, you can do not need watering, directly after planting, the top is covered with plastic film, moisturizing and replenishing water and heating, and the seedlings will emerge soon, if it is planted at the time of planting, the soil is seriously dry, and the potatoes are planted in the soil that lacks moisture, through the potatoes that promote the teeth, although they can grow buds again, but because the rhizomes are in the dried soil, the ability to grow roots decreases, and the water cannot be provided on time, and the nutrients commonly used for potato germination are all given by the mother potato, therefore, The growth of this potato can be severely affected.

Potatoes that have not been mulched with plastic film, if there is no reasonable precipitation before the seedlings emerge after planting, the spring will often cause drought and affect the emergence of potato seedlings, therefore, moderate watering should be carried out for especially arid soils, improve the moisture content in the soil, and let the potatoes have sufficient water to digest and absorb, which is beneficial to the emergence of potato seedlings.

Control the water as much as possible during the potato clump period to avoid the growth of potatoes or the dry soil that affects the normal growth of the potato. Whether potatoes can produce high yields or not, whether the potato plants grow robustly at this stage is more related. Potato watering can only be carried out along the furrow irrigation like a sail, and the water should not be allowed to flood the planting ridge, which will affect the normal rooting of potato seedlings.

For the land lacking fertilizer, it can also be flushed with amino acid water-soluble fertilizer along the stream to cultivate the iron frame for potato harvest.

At this time, it is the time period when potatoes must have more moisture, and the water supply is not sufficient, which usually affects the production of potatoes. At this time, the soil temperature has already risen, and the temperature is relatively high. If the temperature does not rain, you need to carry out watering once a week, potato disease is often associated with the soil is too wet and cold, and the ambient temperature is too low.

Therefore, if there are consecutive rainy days, reduce the frequency of watering as much as possible. Especially in the middle and late stages of potato growth, the interval is about 10 days, and the watering should be stopped, which can alleviate the appearance of potato diseases and increase the storage time of potatoes.

When planting potatoes, you should start watering from the time of bean flower, during this time, the stem will be large, and you need more water to grow up. During the emergence of potatoes, it is necessary to decide whether to water or not according to the situation of land dismantling. Water the potatoes after they have come out, but not too much.

When the potatoes begin to relieve the heat, it is necessary to increase the amount of water for Li Feng, and water it for three consecutive days without rain.

If it is particularly dry, you can use or a few small amounts of water to water, if it is not a special drought, then wait until the time of flowering to water.

Be sure to irrigate when watering, and then ensure that the soil is moist, water once a week, and clean up the stagnant water in time.

Potato plants have very strict soil requirements, and the soil with deep topsoil, loose structure, good drainage and aeration and rich in organic matter is the most suitable, especially the soil with large porosity and good aeration, which can better meet the oxygen needs of root development and tuber growth. 1. When planting potatoes, we should first pay attention to choosing land with fertile soil and loose soil. 2. Before planting potatoes, you need to apply some base fertilizer and cut the potatoes into pieces, which is conducive to the germination of potatoes.

3. When the potatoes sprout and grow to a certain height, the potatoes are planted in the ground. 4. When selecting potato seeds, pay attention to choosing hypertrophied and uniform

Temperature, the normal growth and development of various plants requires a certain temperature to complete the entire growth stage. Potatoes are native to the alpine regions of South America and prefer cooler climates. High temperatures are not conducive to the formation of potato chunks.

Potatoes germinate at 5-7°C and germinate fastest at 12-16°C. However, the soil is wet and cold, and it is not easy to emerge in time after sowing, which is easy to cause rotten seeds. When there is a lot of water and it is not easy to infiltrate, the most suitable soil pH is .

At pH level, most varieties grow well. In acidic soils, the starch content of tubers tended to increase. When the pH of the soil is reached, the growth of varieties that are not tolerant to salinity begins to be affected. 1 You can cut a regular-sized raw potato into two to three pieces, each with one or more eyes, and then these will grow into separate potato plants.

2.Prepare a container. Your container needs to be at least two feet deep because potatoes need deep roots to grow.

A shallower container will result in the harvest of smaller potatoes 3Fill in the soil. 4 kinds of potatoes 5

Water, wait!

The best soils for growing potatoes are soils or sandy loams with high organic matter content, thick soil layers, loose and permeable steep slopes, and plenty of moisture. It has good air permeability, good water storage and soil fixing ability. This soil is conducive to the rapid and neat budding of rhizomes, which contributes to the development trend of rhizomes, and the rhizomes can be successfully grown.

The rhizome that emerges is normal-shaped, neat and commercialized. In areas where there is more precipitation, the method of high ridge planting is adopted, and the sewage ditch is left when planting; In arid climates, irrigation equipment should be gradually added, wells and canals should be repaired, and irrigation machinery and equipment should be purchased to ensure that irrigation is carried out when potatoes need water.
