How to manage peanuts after emergence? How to fertilize peanut yield?

After the emergence of seedlings, top dressing should be carried out at the seedling stage to promote seedling strength and improve yield, peanuts need nutrients after flowering, phosphate fertilizer should be supplemented, and foliar fertilizer should be sprayed on the flower surface.

If you want to improve the yield of peanuts per mu, the first point is to ensure that the number of peanut plants per mu is scientific and reasonable, many farmers have rich planting experience, know how many seeds need to be sown in an acre of peanuts, but it is inevitable that because of the seeds or other external factors caused by planting can not sprout, at this time farmers should timely replant peanuts to ensure that there are enough plants per mu, peanuts after sowing, generally less than a week of time, Peanuts will emerge, so farmers should go to the field for seedling replanting about a week after peanut sowing, and in the process of checking seedlings and replanting, they should see poor seedlings and weak seedlings in a timely manner, and replant seeds to ensure the normal growth of peanuts in the later stage.

After the emergence of peanuts, the seedlings should be checked in time to fill the gap, if it is a film peanut, the seedlings should be picked in time, closed weeding should be carried out before the emergence of seedlings, proper cultivation after the emergence of seedlings, and do a good job in advance to prevent leaf spot disease, etc., in terms of fertilization, the first is the application of basic fertilizer. Organic fertilizers are applied to low-fertility soils, and phosphate fertilizers and urea should follow. Second, before the flowering period, organic fertilizer, calcium, and medium tillage soil are applied.

Thirdly, the addition of phosphorus and nitrogen can be obtained by spraying potassium dihydrogen phosphate and 1% urea solution at the pod-setting stage.

Peanuts are a common crop in rural areas, don't look at it as very ordinary, it is rich in nutritional value. What are peanuts fertilized universally today? What is Fertilizer Production? What are the rules for fertilizer growth?

Peanut. First of all, when are peanuts? What is Fertilizer Production?

Peanut tandem should be determined based on intensity, basal fertilization, and peanut growing conditions.

Peanuts are not too short, and there are few phenomena, there are more shells; Peanuts lack zinc and yellow; The lack of bomb peanuts affects the nitrogen requirement of peanuts and affects yields. At the same time, we have to overcome the habit of using nitrogen, peanuts need nitrogen, not nitrogen in the soil, but through nitrogen in the air, how to promote high yields of arachidon polyamines. Therefore, there is no reason to say that the "peanut manure" of the peasants is unreasonable.

This requires us to fertilize peanuts without too much nitrogen fertilizer. At the same time, we will also apply a large amount of organic fertilizer, medium microelement fertilizer, phosphorus, potassium and various active bacteria, and create a "loose, soft, fat, fat" high rate of life. In order to meet the demand for high yield and quality of peanuts.

In the positive direction of the organic microbial package pure fertilizer, collect nitrogen and phosphorus phosphorescent multi-organic fertilizer, humic acid organic fertilizer, medium-sized micro-inner membrane fertilizer, multi-functional compound microbial fertilizer, four-functional, intelligent regulation, continuous release of long-term terminology, promote peanut more tumors, less disease, especially peanut rot, crown rot, baking soda, focal diseases and other pathogens, and have a good killing effect on underground pests such as rickets.

Second, what are the laws for peanut growth?

Peanuts are the crop with more oil and protein. Usual growth and development requires various elements such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, zinc, copper, iron, manganese, which requires the most nitrogen and peanuts have nitrogen, but the seedlings are not nitrogen until they are formed. Nitrogen fertilizer should be sufficient to promote seedling growth at the seedling stage.

Phosphate fertilizers can promote peanuts, full particles, and improve pods. Potassium uptake is very large, potassium is facing the growth of stems, shells and nuts, the effect of potassium fertilizer is obvious, soil, soil land land. Other elements can provide a state based on soil nutrients, and they can be used for sexual use.

Peanuts have a strong ability to breathe, in addition to roots, fruit needles, young fruits and leaves directly absorb nutrients. Peanuts have different fertilizers and the amount of nutrients required at the seedling stage is small. The absorption of nitrogen, phosphorus and potassium accounts for only about 5 of the total absorption.

The amount of absorption and nutrients increases dramatically during the flowering period. Nitrogen absorption accounted for 17 of the total content, phosphorus accounted for and potassium accounted for; The POD period is the period of vegetative growth and reproductive growth of peanuts, forming a large number of pods, as well as the most nutrient absorption, and nitrogen absorption accounts for all absorption. 42 amounts, 46 of phosphorus, 60 of potassium; The ability to absorb nutrients gradually increases during maturation, with nitrogen uptake accounting for 28 percent of the total life expectancy and phosphorus accounting for 7 percent.

When planting peanuts, it is necessary to fertilize more after flowering, because a large amount of fertilizer will be consumed during this period, and it is necessary to replenish it in time, adding fertilizer about once a week, so that the nutrients are more sufficient.

Peanut fertilization is not a one-time can, in the whole growth process, should be fertilized about 3 times, respectively, seedling fertilizer, flower needle fertilizer, podding fertilizer. At each stage of peanut growth, it should be decided what fertilizer to use according to its growth characteristics, so that the peanut yield can be higher.

The cultivation of plants is inseparable from fertilizers, especially if you want to obtain high-yield, high-quality peanut fertilizer, phosphorus, potassium fertilizer, human manure and plant ash mixed farm fertilizer. It should be noted that different fertilizers should be applied in different growing seasons of peanuts. Third, the time and method of planting peanut topdressing should be clear!

Timely topdressing of peanuts can promote early emergence of seedlings and improve the quality and yield of peanuts, so it is very important to fertilize at what time and what fertilizer to fertilize. 1.Top dressing time of peanut (1) The application of fast-acting nitrogen fertilizer and Huawang No. 3 at the seedling stage (growth of 3-5 leaves) can promote more flowering and branches of peanut, and can increase the number of flowers and pods.

2) Apply nitrogen fertilizer after peanut flowering, compound fertilizer and calcium fertilizer at flowering. (3) Apply phosphate fertilizer in the full stage of peanut pods, spray potassium dihydrogen phosphate plus new high-fat film spray every 7-10 days, and spray it two or three times in a row.

The demand for potassium is close to half of the whole growth cycle, and some nutrients are transported to flowers, needles, and young fruits. Urea and potassium dihydrogen phosphate can also be sprayed to supplement nutrients. In the summer, the heat is hot and muggy, and the leaves of the peanuts are all sun-dried. High temperature and drought will affect the pin-forming pods of peanuts, the soil is not moist when the soil is dry, the fruit needles cannot penetrate the soil, and the formation of pods cannot be completed by growth and development, which will cause a reduction in yield.

Peanut farmers know that peanuts like stubble, planting is afraid of heavy stubble, heavy stubble peanuts are generally small, yellow, early deaf, pests and diseases, few fruits and small, usually can only reach 70% to 80% of the normal yield, so peanut planting must be staggered heavy stubble. In the application of basal fertilizer, on the one hand, it should be carried out in accordance with the principle of "organic fertilizer as the mainstay, supplemented by chemical fertilizer", on the other hand, the basal fertilizer should be applied as deep as possible, and at the same time, it should be reasonably matched with the ratio of various nutrients and pay attention to the supplement of medium and micro fertilizers.

The first topdressing is after wheat harvest and early stubble topdressing before peanut clusters, and the amount of fertilizer is 30 40 kg of peanut fertilizer per mu, or 10 kg of urea, 15 kg of diamine, and 10 kg of potassium chloride. The second topdressing is in the beginning of the expansion period of young fruits, and 10 kg of urea per mu is generally applied. If peanuts want to bear more fruits, the prevention of pests and diseases is also very important, there are two main types of diseases, one is peanut leaf diseases including leaf spot; the other is root diseases such as root rot; The main insect pests are grubs and needleworms.

Peanut seedling stage, can be said to be the key period of peanut planting management, peanut seedlings emerge, seedlings are strong, seedlings grow vigorously, rapid growth after seedlings emerge, and play a great role in the yield of peanuts. Potassium dihydrogen phosphate is a binary chemical fertilizer containing phosphorus and potassium, which is widely used in agricultural production. Spraying potassium dihydrogen phosphate at the seedling stage of peanut can supplement phosphorus and potassium through foliar surface, promote the growth of peanut roots, strengthen peanut growth, and enhance stress resistance.

It is a good measure to increase production.

At the seedling stage of peanuts, attention should be paid to the density of planting, and the soil should be selected to be loose, but should be applied to him with fertilizers that are conducive to the growth of roots.

The peanut seedling stage is mainly to do a good job of weeding and pest control, and the mid-term field management should apply a small amount of nitrogen fertilizer and spray zinc fertilizer in time to the yellowing field management. The bottom fertilizer is used to fill the total growth of the field, and it is necessary to spray pesticides such as polycarpus and dwarf harvest to control the excessive growth potential of flowers and more fruits. During the growth of peanuts, pesticides should be sprayed once or twice to prevent damage to the fruit by underground pests.

The most important thing in the peanut seedling stage is the prevention and control of pests and diseases, common root rot, stem rot, aphids and so on. It can be controlled by seed dressing, root irrigation, foliar spraying and other methods. Apply fertilizers containing nitrogen, phosphorus and potassium.

Apply the right fertilizer to grow vigorously, apply the wrong fertilizer is easy to hurt the roots and seedlings, and apply peanuts in spring, there is 1 point to pay attention to.

1.Replenish the seedlings. After the peanut seedlings emerge, the first thing to check is the growth of the seedlings, and if there is a large area of the plot lacking seedlings, the seedlings should be replenished. Seedling replenishment is generally carried out between ten days and half a month after sowing.

2.Weeding. When the peanut seedling stage is the best period for weeding, generally start to spray herbicides when the weeds have 2-4 leaves, before 10 o'clock in the morning or after 15 o'clock in the afternoon, according to different weeds, choose not to use the agent.

3.Topdressing. When peanuts are in the seedling stage, they can be topdressed, generally before the first flowering, in order to promote the germination of seedlings.

However, not all plots need to be topdressed, such as plots with good flower growth, vigorous leaves, and darker colors, you can choose not to top dressing. Top dressing is mainly carried out in the place where the growth is weak and the leaf color is light and small when the peanut has 4-5 leaves, mainly phosphate fertilizer and potassium fertilizer.

4.Watch out for leaf spot. Peanut leaf spot disease generally occurs after peanut seedlings.

First of all, the leaves will be infected, and the lesions will gradually spread from the lower part to the upper part, and then the peanut stems will also be invaded into lesions, and at the same time, after being infected with the pathogens, the root growth will be hindered, and the flower growth will be slowed down, which will affect the normal growth of peanuts. If the disease occurs, you can choose the agent carbendazim, chlorothalonil, methyl tobuzin, etc., when encountering a more serious plot, it is not good once, you can wait for about a week, and come several times.

After the peanut emerges, we must pay attention to the suitability of the water source and soil. If the land is dry and water-scarce, then it is important to water the peanuts to ensure that they receive the right water every day so that the peanuts can thrive.

Water and fertilizer management.

Peanuts in the plot with sufficient bottom fertilizer do not need to be topdressed, and the plot covered by plastic film is not convenient for topdressing. If there are weak seedlings and seedlings with green leaves, you can focus on fertilization to ensure the normal growth of the plant. For example, in some replanted plots, when replanting, you can chase a little fertilizer to promote growth.

After the seedlings grow, we should manage the weeds in the field and pull out the weeds, so as not to consume more nutrients, reduce the nutrients of peanuts, and ensure the quality of peanut harvest, because weeds will share the nutrients of peanuts, so we should pay attention to removing weeds.

After the seedlings grow, we should also pay attention to fertilization, to ensure the strong growth of the seedlings, high yield at the time of harvest, pay attention to the growth of the seedlings, proper watering, in addition to watering and fertilizing, we should also pay attention to prevent the destruction of pests and diseases to the seedlings, peanuts have more pests and diseases, we should not use a single pesticide treatment, should be a variety of pesticides to treat the seedlings.

In order to increase the yield of peanuts, it is necessary to ensure the vigorous growth of the plant, after all, only if there are enough branches and leaves, can more nutrients be provided. The growth of branches and leaves requires a lot of nitrogen, which is well absorbed and works very quickly. Especially during the flowering and podding period, urea solution should be sprayed every other week or so, which can ensure the ** nitrogen level, make the plant grow more vigorously, and be conducive to flowering and peanut podding.

<> should not apply too much phosphorus and potassium fertilizer when paying attention, otherwise it will have adverse effects on seedlings. If the basal fertilizer is insufficient when fertilizing at the seedling stage, then it should be applied in time before the first flowering, mainly nitrogen fertilizer, and the fertilization method is mainly sprinkled and furrowed. Especially during the flowering and podding period, urea solution should be sprayed every other week or so, which can ensure the ** nitrogen level, make the plant grow more vigorously, and be conducive to flowering and peanut podding.

Peanut fertilizer management 2: skillful application of phosphorus and potassium fertilizer.

It is rich and relatively complete in nutrients, and also contains organic matter that can improve the soil structure. Chemical fertilizers contain single nutrients and high content of nitrogen available nutrients, and the combined application of the two can promote each other, improve fertilizer efficiency, improve soil structure, and continuously cultivate soil fertility. Fertilizer supplemented with trace elements for peanuts, ferrous sulfate solution can be used to supplement iron for peanuts, boric acid or borax water can be used to supplement peanuts, zinc sulfate can be used to supplement zinc for peanuts, and sprayed according to the situation.

Top dressing nitrogen fertilizer at flowering needle stage can refer to top dressing at seedling stage. In addition, according to the characteristics of peanut fruit needles and young fruits that directly absorb phosphorus and calcium nutrition, 10-20 kg of superphosphate and 150-250 kg of high-quality circle fertilizer can be applied per mu, which can improve the phosphorus and calcium nutrition of peanuts and increase yield significantly. The "pods" grow in the ground, with a hard shell on the surface, and inside are delicious peanut kernels.

As an important cash crop, its market is relatively large and relatively stable, so for farmers, the benefits are also relatively high.
