When planting peanuts, what do you need to pay attention to in the later stage?How to manage to be p

Peanuts sown in the summer also enter the late stage of peanut growth. The late growth stage of peanut refers to the late pod and cannon fruit ripening period in peanut growth, and the peanut enters the late growth stage after 30 days of flowering of summer-sown peanuts, which lasts for about 50 days. The pause in the early and middle stages of peanuts, fertilizer, seed selection and preparation, sowing density, sowing quality, etc. are the basis for high yield of peanuts.

In the later stage of peanut growth, the growth of stems and leaves began to stagnate slowly, and the growth of pods was vigorous, which was mainly the key period of pod growth. The high-yield appearance of this period is that the stems turn yellow, the leaf color is normal, and the fruits are double.

So the management precautions for this period. The main purpose is to ensure the stable growth of stems and leaves on the ground, as far as possible without disease spots or few disease spots on the leaves, late disease spots, and prolong the function of stems and leaves. Keep the soil dry and wet to ensure the quality and high yield of peanuts.

Maintain the autumn rain outside the roots, and the steady growth of stems and leaves. According to the growth situation, foliar spraying was used to harvest fertilizers and plant growth regulators such as potassium dihydrogen phosphate (suitable concentration of 3%) or urea (suitable concentration of 2%) to promote particle formation. At the same time, trace elements are sprayed on the foliar surface to preserve the flowers, increase the fruits, and prolong the functional period of the leaves.

Generally about 40 days after flowering, sprinkle 2 3 times every 10 to 15 days.

There is little need for water in the later stages of growth, but when there is drought, the roots are prone to decay, the top of the head drops, the stems wither, and the saturation rate decreases. Therefore, if the soil moisture does not meet the normal growth needs of peanuts, they should be watered immediately. In particular, sandy land should be supplemented with roots and leaves to increase the saturation rate.

When watering, do small water or ditch irrigation and do not let large water overflow. Rainwater should be removed in time. Too much moisture can affect the viability of the roots, producing pod sprouts and even rotten fruits.

Peanuts require very few nutrients in the later stage, but the formation of yield and pod fullness also have a great influence on the improvement. The absorption capacity of peanut root is weakened in the later stage, and 3 2 1 2 potassium dihydrogen phosphate are mixed and sprayed every 30 catties from the later stage of the pod. 2 3 consecutive sprays every 7 10 days, 3 barrels per acre.

It can effectively prolong the functional time of the upper lobe and improve the satiety of the pod.

In the later stage of peanuts, there is a lot of rain and high humidity in the field, which is prone to leaf diseases such as peanut brown spot and black spot, and stem rot. At the same time, red spiders, cotton bollworms, horses, Meng Lincai, etc. also continue to harm the leaves. According to the occurrence of pests and diseases, it can be prevented in time in combination with foliar fertilization.

Fungicide added 15 grams of 10% phenylethethyl ether cresol water granules, or 10 ml of 40% silicone oil, or 15 grams of 50% ethylamine per barrel. Insecticides can choose pyrethrin, nail rhinitis, chlorantraniliprole, etc., mixed with mites, enzhongmine, thiamine, etc. Put 15 ml of avermectin in the compartment with red spiders.

The general interval is 5 7 days, two consecutive precautions, which can control the risk.

In daily life, do you know what you need to pay attention to when planting peanuts? How to manage to be productive?Peanuts should be relatively common in life, and farmers usually like to plant peanuts very much in the process of planting.

It is also very popular in the market, and it is actually very simple when growing peanuts in the early stage. However, in the later stage, the management should be relatively meticulous to ensure the normal growth of the plant. When planting peanuts, trace elements such as calcium, phosphorus and molybdenum boron should be supplemented during their growth.

The effect of calcium and phosphorus fertilizer is to make the peanut shell form well, and at the same time, the peanut particles are full. If calcium and phosphorus fertilizer is insufficient, peanuts are prone to a lot of empty pods and the particles are not full. The time to apply this phosphate fertilizer is best between the second and third weeks after the peanut flower needles have been put into the soil, when the fertilizer can be used to promote the formation of peanut pods.

The function of molybdenum boron fertilizer is to increase the yield, generally starting at the beginning of peanut flowering and continuing to the whole growth stage, spraying on the leaves of peanuts.

Perform an out-of-roots fertilizer spray.

In the later stage of peanut growth, the growth of stems and leaves will gradually stagnate, and the growth of pods will gradually increase, and the nutrients will also need to be sufficient, and at this time, the root absorption capacity is relatively weak, and it is easy to defertilize and premature aging, which requires extra-root spraying. 1%-2% urea aqueous solution can be used, sprayed once a week, and fertilizer can be sprayed two or three times in a row.

What needs to be noted in the later stage is that the planting process must be mastered well, and if you want to have high yield, you should water more and fertilize more, so as to achieve a very ideal effect, and there will be no out-of-production.

For high peanut yield, use Fengxin Agriculture's peanut high yield program.

Fuda "two mixes and three sprays" peanut high-yield technology.

Peanut is the late stage of growth and development, at this time, the root vitality is weakened, the peanut is immature, and the leaves have the phenomenon of premature senescence such as drying, yellowing and falling off. In the early stage, too much imidacloprid is used to control the prosperity, which is particularly prone to the problem of premature aging of leaves and yellow leaves.

<> temperatures are still high, sometimes dry or rainy. In the event of a drought, the humidity in the field is low, the root system declines prematurely, causing the leaves to fall off and the dried fruit of peanuts increases. On the contrary, when there is a lot of rain, peanuts are easy to emerge and do not spit fruit.

If the drainage is not timely, the flower roots will rot easily, and the peanut pods will rot or sprout. The land on the side is only 20 centimeters high, and there is no need to control the growth of this kind of land.

Lao Zhao said. "By the way, it is necessary to judge the length of the peanut by the height of the peanut, and the time to see the needle into the ground. After controlling the prosperity, if the plot is still vigorous, spray it again.

In the later stages of peanut growth, fertilizer should be refertilized. The same fertilizer should be sown in the early stage, and fertilizer can be removed in the later stage. Therefore, fertilizing can promote the growth of pods and prevent premature aging"。

In addition to controlling the prosperity and topping, Lao Zhao said that there is no good way to control pests and diseases, mix seeds before sowing, pay attention to drug prevention from the seedling stage, and add some trace elements to improve the disease resistance of the plant, so that pests and diseases will be reduced, there are a small number of serious peanuts, do not feel bad, pull out in time. Judging from Lao Zhao's management methods, his planting experience is to control the excessive growth of peanuts in the middle stage, and to prevent premature aging and ensure the yield of peanuts in the fast maturity period. It is only through such management that high yields of peanuts can be achieved.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you guys have any ideas, you can let us know in the comments below.

To ensure the stable growth of stems and leaves, the soil is moist, the method of fertilization should be foliar fertilization, you can use some urea, the concentration of urea should be kept at about 3% or 2%, and then some trace elements should be sprayed on the page, 40 days after flowering, every 10 15 days 2 3 times on it, if you want high yield, you should choose molybdenum boron fertilizer, spray directly on the leaves.

It is necessary to pay attention to the growth of the flowering period, but also to pay attention to the prevention and control of drugs, do not miss the planting time, choose good soil for planting, pay attention to the amount of fertilization and watering in the later management, and be sure to control the temperature. It is necessary to loosen the soil frequently, but also to carry out spraying management, to prevent insect pests in advance, and to learn some skills during management, so that you can achieve high yields.

Although peanut does not need a lot of watering in the later stage of production, in case of dry weather, the root system of peanut is easy to decay, resulting in wilting, drying and falling off of the parietal leaf, thereby reducing the satiety rate and reducing the yield. Continuous rainy weather can cause poor drainage in the field, which can lead to water accumulation, affecting root viability and pod development, and in severe cases, even rotting fruit.

If there is continuous rainfall in the later stage of peanut growth, it is easy to lead to water accumulation, resulting in peanut root rot, weak plant growth, and waterlogging, so it is necessary to drain water in time. However, if there is no precipitation for a long time in the late growth stage of peanuts, then it is easy for the roots to dry up, causing the peanut leaves to fall off, so once it is found that there is no precipitation for a long time, it is very important to water in time. Long flukes are very common, and they are so harmful that the pods in peanut fields can be eaten.

Therefore, in the later stage of peanuts, it is also very critical to control this underground pest. When peanuts enter the late growth stage, there is also a common phenomenon, that is, premature aging, which is usually due to nutrient deficiencies, and it is recommended to use foliar sprays to prevent premature aging of peanuts.

Watering water. Peanuts have a greater demand for water in the process of growth, so if you want to make peanuts have high yields, in the later stage of maintenance, you can also provide mineral-rich river water and pure water to soak all the soil, and you need to pay attention to the amount of watering in the process of watering, it is best to water it when the soil is dry, and postpone watering when the soil is wet.

In the later stage, it is mainly to ensure the steady growth of aboveground stems and leaves, so that there are no or few lesions on the leaves as much as possible, and the lesions appear late to prolong the function of stems and leaves. Keep the soil dry and wet moderately to ensure high quality and high yield of peanuts. 1. Top dressing outside the roots to ensure the steady growth of stems and leaves, 2. Reasonable watering, drought watering and waterlogging drainage, 3. Prevention and control of pests and diseases.

Peanuts should be fertilized in the later stage, so that peanut seedlings can grow more vigorously and grow more.

It is necessary to strictly manage water and fertilizer, and control the humidity and temperature in the greenhouse, so that the peanuts can be highly produced.

In recent years, many farmers have often used the drug three times when planting to increase the yield of peanuts. The three spraying of peanuts refers to the spraying of peanuts once at the critical stage of growth to prevent insects, diseases and nutrition, so as to increase yield and improve quality. In addition to watering and fertilizing, it is also crucial to use peanut three times correctly, mainly the formula and spraying time.

After the peanut emerges, check the seedlings, and then pay attention to whether there are pests and diseases, whether there is a lack of water and fertilizer. Many farmers ask if the first medicine can be used after it emerges. For the first time, it is recommended to use it after the seedlings are sown and before the flowering begins.

It is best to use it during this period when the seedlings have grown two true leaves and 50% of the plants have produced their first flowers.

Spraying too early, the seedlings have small leaves and weak absorption capacity. And there is no way to choose chemicals based on growing conditions. If spraying too late, it can not promote roots and flowers, and the seedling growth will be poor, which will affect the later growth.

Therefore, the time of the first spraying should be grasped. In addition, the formula for the first spray is special. Some farmers mainly use foliar fertilizer, while others mainly use pest and disease control, which can be decided depending on the growth of the plant.

For example, some plots are planted with continuous crops and peanuts all year round, and soil-borne diseases are quite serious. Root rot and crown rot can lead to the death of seedlings and trees. Then, the application of nutrient foliar fertilizer is mainly to promote plant growth and early flowering.

Therefore, it is very important to prevent diseases and supplement fertilizer.

Fungicides such as difenoconazole and dioxazine are commonly used for disease prevention. Before sowing, there is generally no plot of seed dressing, the disease is serious, and we must do a good job in the prevention and control of the pests in the month to aphids and underground pests, and the use of systemic drugs for seed dressing, the effect of post-seedling control of aphids is ideal. Imidacloprid can be added when aphids appear.

In the first application, there are many kinds of foliar fertilizers, such as urea, potassium dihydrogen phosphate, boron fertilizer, molybdenum fertilizer, and some regulators. If the content of nitrogen, phosphorus and potassium in the base fertilizer is sufficient, boron and molybdenum can be used to promote the flowering of rhizobia and improve the nitrogen fixation capacity. Molybdenum fertilizer has been used for seed dressing, which can be used after flowering, and does not need to be sprayed at the seedling stage.

Seed dressing and foliar sprays work best. The addition of brassicin to foliar fertilizer can improve the stress resistance of plants, such as high temperature and drought at the seedling stage, and promote plant growth.

Generally speaking, peanuts can be sprayed with difenoconazole, difenoconazole, dichlorfen, boron fertilizer, molybdenum fertilizer, and brassinin from the seedling stage to the flowering stage. When spraying, dilute the nutrient fertilizer first, then add fungicide, and try to spray in the morning or afternoon, so that the absorption effect is better.

In the planting process, according to the softness of the soil and the growth rate of the plant, the soil should be properly cultivated. Foliar fertilizer can not only provide water for leaf growth, but also promote leaf growth rate, enhance photosynthesis, and increase nutrient accumulation in plants.

In order to produce fruitful and high yields, peanuts should first be planted in moist and non-slabbed sandy soil, not loess or soil. Since the root system of peanuts needs loose and highly aerated and active soils, semi-wet sandy soil planting is preferred. The second is fertilization, which should be carried out before planting insecticide and soil fertilization and fertilizer storage, and the fertilizer should be used organic or farmhouse fertilizer for shallow soil burial.

Peanut three times is sprayed once at the key growth stage to prevent insects, diseases, and nutrients, so as to achieve the effect of increasing yield and improving quality. In addition to watering and fertilizing, it is also crucial to use peanuts three times correctly, mainly in terms of formulation and spraying time. After the peanut seedlings emerge, it is necessary to check the seedlings and replenish the seedlings, and then pay attention to whether there are pests and diseases, and whether there is a shortage of water and fertilizer.
