Growing peanuts in the south, do you think you need to control the prosperity?

The peanut planting area in China is relatively extensive, and the peanut planting in the south is mostly summer peanut. Compared with the peanut growing areas in the north, the rain is generally more abundant, and the peanut plants generally grow vigorously. In order to increase the yield of summer peanuts, it is generally necessary to control the prosperity.

The purpose of <> peanut control is to control the growth of plants, avoid the imbalance of asexual growth and reproductive growth, so that peanuts only emerge from seedlings and do not bear fruit, so as to improve the yield of peanuts. Peanut control generally chooses chemical control, that is, the use of popularizers, commonly used prevention and control of popularizers paclobutrazol and must control Wang, should be the southern weather is hot, and the rain is sufficient, with these two necessary conditions peanut growth is very strong, if you do not go to the popularization agent, there will be peanuts lush, and pick up not many peanuts; Whether it is the south or the north, the flower grows to about 30 cm, and it can be properly sprayed.

Farmers all know that once the soil is fertile and the temperature is conducive to the growth of stems and leaves, peanuts are prone to growth. This will lead to an imbalance between supply and demand of nutrients in a short period of time and a lack of nutrients in the later stage. This will lead to a great impact on peanut flowering and fruiting, late fruiting, relatively dry grains, and reduced yields.

If the fruit stalk has grown to 30-35 cm, extra attention is required...If the growth rate is fast, it needs to be controlled in time. Make sure the stems are under 60 cm when they are ripe.

There is also a method of judgment, which generally requires special control after 50 days after sowing, and the analysis at this time is more accurate. After the house is built, it will be returned to you, or you can ask for money at one time without a house, which depends on your choice.

Do a detailed interpretation of the problem, I hope it will help you, if you still have any questions, you can leave me a message in the comment area, you can comment with me more, 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.

Planting peanuts in the south needs to be controlled, because this can improve the yield of peanuts, so that each seedling peanut grows very well, the flesh will be relatively full, and there will be no small peanuts and poor quality.

Yes, because in this way, the yield of peanuts can be guaranteed, the fertility of the soil can be guaranteed, and the work of insecticide and weeding can be done in the planting process, and then the low yield of peanuts can be prevented.

I feel the need for it. If it grows too vigorously, the fruit is relatively small, and the yield is not particularly high, so the plant should be controlled.

It needs to be empty, because the temperature in the south is relatively high, and if it is not controlled, it will definitely affect the yield of peanuts.

If there is a lot of rain in the peanut flowering and needle stage, the peanut seedlings will grow rapidly, and when it exceeds 40 cm, it is necessary to control the prosperity and spray it in the later stage of peanut flowering. Peanuts can not be used during the full flowering period. Peanut control agent is generally recommended to be used when the plant height is 35 cm after the peanut is sealed.

Another reliable standard is to use the anti-growth agent from the needle stage to the pod-setting stage (after the peanut blooming stage and when the underground fruit grows to the shape of a chicken's mouth). If the drug is used too early, there may be fruit shrinkage, resulting in a decrease in peanut yield.

If the peanut is in full bloom or just flowering, it will lead to the phenomenon that the peanut fruit does not grow.

When the peanut control pesticide is used, it must be used according to the rainfall, and the amount of one use must not be too large, if the peanut is still strong after use due to the large rainfall, the peanut can still be sprayed many times, but it must not rely on increasing the amount of medicine to control the growth.

It is necessary to control the prosperity. Choosing well-drained, loose soil, choosing seeds with full grains suitable for the local climate, and proper fertilization during peanut growth are all keys to high peanut yields.

First, the benefits of peanut seedling control.

Controlling the growth of peanut seedlings can make the peanut plant strong, the root system is developed, the roots are strong, and the leaves are green and thick. Promote the branching of peanuts, more side branches to help the differentiation of flower buds, flowering, peanut branches grow robustly, promote the flowering of peanuts, especially around the roots to form effective needles, more pods, the formation of effective pods, in the peanut seedling stage to control the prosperity, help the peanut high yield in the later stage.

Second, the time of peanut planting.

The first time to control the bloom, generally when the flower grows to 5 to 6 leaves. You can control the wang, at this time the wang can increase the branching of the peanut, because the main stem of the peanut is not under the needle, so the more branches will occur, the higher the yield. At the time of branching, 20 grams of polynidazole per mu are used to control the vigor, which will increase the branching of peanuts.

The second time is to control the growth of the fruit during the expansion period after the end of the needle, which can control the growth of the aboveground part and supply all the nutrients to the following parts.

3. Steps to make peanuts highly productive.

If you want to make peanuts productive, early management is very important. First of all, before planting, choose a soil that is fertile and loose, and can ensure that it has good drainage. In this way, the growth of long flowers in the future can be guaranteed to be good and the yield is high.

Because peanuts do not need much water in the later stage, if the drainage is not good, the stored water will cause the peanut cheeks to rot and affect the yield. When choosing peanut seeds, be sure to choose excellent seeds with full grains, suitable for the local climate and strong disease resistance. This can lead to some unnecessary pests and diseases during peanut cultivation.

Finally, pay attention to the top dressing of peanuts, the fertilizer nutrients required at each growth stage are also different, and some nitrogen fertilizers can be paid attention to in the early stage of peanut growth. In the middle of peanut growth and flowering and needle placement, you can add some powder fertilizer. Therefore, if the planting of peanuts is well managed in the early stage, it is very conducive to the high yield of peanuts.

If you want to have a high yield of peanuts, you must learn to control the prosperity, but also increase the planting density and increase the application of fertilizer. Before and after the eruption of pesticides, pay attention to maintaining soil moisture in the field to ensure the normal growth of plants. Excessive drying, negative nutrient absorption, and increased peanut inhibition led to single-kernel phenomenon.

What do peanuts use to control Wang?

Peanut control is mainly the use of growth regulators, but farmers should strictly control the dose, if the dose is too high, it will have an adverse effect on the growth of peanuts. Common means of controlling the growth of peanuts include the application of chemicals. If the dose is too large, the shell of the peanut pod will become thicker and smaller.

These agents remain in the soil for a long time and can easily inhibit the growth of the next crop after the peanut is harvested. <>

What causes peanuts to be low in constant?

In the process of growing peanuts, due to climate and fertilization, farmers often cause peanuts to grow vigorously, resulting in peanut deposition and reduced yields. Spraying is an effective measure to control peanut overgrowth. However, producers often have incorrect practices, such as premature control of time and overuse, resulting in inhibited peanut overgrowth, early defoliation in the later stages and significant early sedimentation affecting the formation and accumulation of photosynthetic products.

A variety of flexible regulation can ensure the reasonable growth process of peanut, coordinate nutrient distribution, and effectively prevent premature aging and yield reduction.

What is the most used peanut control method?

At present, the most widely used peanut control is chemical control. Plant growth regulators are used to control the growth of peanuts. However, there are drawbacks to the use of medications.

It can prevent the growth of peanuts at one time, which is easy to cause disease in the later stage, accelerate the premature aging of peanuts and reduce yield. Secondly, for peanut fields with poor fertility, it is not recommended to use drugs to control prosperity. It is best to use human intervention to control growth.

This method is suitable for growing peanuts in small plots. If you want to have better results, it's best to do it after rain or after irrigation and when the soil moisture is right. It speeds up the time it takes for peanut needles to enter the soil, forming more pods and increasing yields.

Peanuts need to be controlled or not, to see the sky, the ground, and the growth, not blind. For peanut fields with normal light and precipitation, normal soil fertility and normal plant growth, there is no need to invest manpower, material resources and financial resources to control prosperity, but for peanut fields with more rainy weather, sufficient soil fertility, excessive use of nitrogen fertilizer, excessive soil moisture, excessive planting density and excessive seedling growth, it is very necessary to carry out special control treatment, so as to promote the development and transformation of peanuts from the growth of above-ground stems and leaves to the development of flowers and pods. On the contrary, it can increase the yield of peanuts in the later stage and improve the quality of fruit pods.

Peanuts are vigorous and may occur in the seedling stage and in the middle and late stages of growth, but it is most likely to occur in the middle and late stages of growth with high temperature and sufficient fertilizer and water. In terms of the method of controlling the vigor, on the one hand, it is recommended to clear the seedlings and squat the seedlings at the seedling stage (after the seedlings are gathered, the topsoil around the seedlings can be peeled off, so that the two ** leaves of the seedlings can leak out of the ground), or when the flowers grow 5-6 leaves, 300 times of 15 paclobutrazol is used for spraying; on the other hand, drug control is carried out after peanut flowering to the needle drop period; On the other hand, moderate water and fertilizer control should be carried out for vigorous peanuts to inhibit continued growth.

It needs to be controlled. According to local conditions, choose improved varieties, different peanut species, different varieties of planting areas, but also pay attention to crop rotation, do not plant peanuts in the same field for many years, otherwise even if fertilizer is increased, the yield of peanuts will not be too good. Peanut seed selection peanut seeds can dry the seeds before sowing, promote the maturity of the seeds, can effectively improve the rapid germination of seeds, seedling emergence operation, peanut peeling time from the sowing period as close as possible.

If the soil moisture for sowing is suitable for sowing, if the soil is too sandy, take the soil one step seed, and inhibit the soil in time after mulching, so as to avoid soil hardening and impact, and pay attention to the emergence of peanuts in this aspect of the problem.

This is certainly needed. When the peanuts are 30 centimeters tall, they should be controlled. Be sure to water in time, ensure that the water and fertilizer are sufficient, and also pay attention to the density of cultivation.

Peanut is a game process of vegetative growth and reproductive growth, especially in the peak control period after the full flowering period, reproductive growth is the main thing, and vegetative growth is supplemented. Fertilizer control during the peanut growth period can slow down the continuous growth of peanut plants at the podding stage. During peanut planting, basal fertilizer should be applied as much as possible so that top dressing is not required in the later stages of growth.

Due to the great demand for trace elements in peanuts during the flowering period, it is necessary to supplement some trace elements such as boron and molybdenum to effectively ensure the nutrients during the flowering period. It is difficult to control fertility because it can easily cause the fruit of the plant to suffer from insufficient fertility, affecting yield and quality.

The essence of peanut control is to inhibit the growth of vegetative organs such as stems and leaves, promote flowering and fruiting, transform into reproductive growth, and achieve increased yield. Improper field management and excess water and fertilizer in the early stage will lead to vigorous growth. If the flowering is not controlled in time, it will lead to late flowering, or even less flowering, and severe flowering.

The distance from the soil surface is large, so that the needle cannot penetrate the soil. Slowly degenerates, resulting in a situation where only seedlings grow and do not bear fruit. Peanuts are a crop with a well-developed root system.

Before sowing, land preparation generally requires loose, fine, non-compacted, moderate water content, and convenient drainage and irrigation, so that the growth and development of peanuts are always in a suitable soil environment.

Peanut has few root nodules in the early stage of growth, weak nitrogen fixation ability, and has been buried in the middle and late stages of growth, which is not suitable for fertilization. It is very important to apply sufficient basal fertilizer to peanuts. Generally, before sowing, combined with land preparation, sufficient basal fertilizer is applied at one time to meet the fertilizer needs of the whole growth period.

Peanut seedlings should be inspected in time after emergence, and the seedlings should be replenished in time in places where there is a serious shortage of seedlings, so that the number of seedlings per unit area can meet the planned requirements, generally carried out 3-5 days after the emergence of seedlings. Peanut is afraid of both drought and waterlogging, and the irrigation cycle is mainly determined according to the precipitation and distribution of peanut at each growth stage, soil water content and soil moisture requirement. Peanut is a drought-tolerant crop, but it has poor waterlogging tolerance, excessive water in the field, and lack of air in the soil, resulting in poor root development, less root nodules, weak nitrogen fixation ability, short yellow plants, increased flowering nodes, difficult needle dropping, decreased seed setting rate and fullness rate, and increased fruit rot, which seriously affected the yield and quality of peanuts.

It is necessary to sow seeds at the right time to reduce the occurrence of pests and diseases.

The 24 solar terms are closely related to farming. Just like we grow spring peanuts in the south, if they are planted too early and the temperature is lower than 15, the peanuts will not germinate; If it is too late, due to the influence of external factors, it is very easy to attract pests and diseases. Peanuts are warm-loving and sun-loving crops that are not cold-tolerant, and the 24 solar terms song is the wisdom of the ancients in our country.

When it is above 30cm, it is necessary to take drugs to control Wang. It is necessary to apply fertilizer skillfully, and do a good job of seed treatment before sowing to improve the vitality of seeds.

To regulate the growth of peanuts, do not hope that the growth can be controlled overnight, which does not conform to the normal growth law of peanuts. Correct use of the method of controlling the peanut, gradually control, in the flowering stage, the needle stage and the pod-setting stage of peanuts, according to the requirements of the foliar spray chemical control agent. After a large number of peanut flower needles are put into the soil, the peanut field with more vigorous growth and lodging risk is controlled to coordinate vegetative growth and reproductive growth, promote peanut pods, and achieve the effect of increasing yield, which is more labor-saving and the effect is also good.
