Can I plant peanuts without bottom fertilizer and then apply top dressing?

Let's take a look at the law of peanut fertilization and how to top dress.

Peanut is an oil crop with more oil and protein, and the yield has a great relationship with the increase in fertilizer, and the most needed are the four elements of nitrogen, phosphorus, potassium and calcium.

Peanut in different growth periods of nutrient absorption law is different, from seedling to flowering, due to the small plant, the need for nutrients is relatively less, but if the lack of nitrogen nutrition, the seedling yellowing, weak growth, branching and flowering will be reduced, affecting growth and development, and ultimately affecting the yield.

Peanuts in the pod-setting stage, is the period of the largest growth, that is, to maintain the growth of the plant, but also to concentrate the growth of nutrients ** pods, so it is the period of the greatest fertilizer demand, especially the greatest demand for potassium. The peak demand for calcium is also at this time.

If there is a lack of fertilizer in this period, the fruit will be small and small, the amount will be small and light, and the yield will be low.

When the pods are full to maturity, the absorption capacity of the root system gradually weakens, but a certain amount of nutrients are still needed to enrich the pods, but the potassium absorption has been reduced to a minimum.

It has been proved that when soil fertility is low, nitrogen deficiency is general, and phosphorus deficiency is severe, especially in mountainous and thin soils, increasing the application of bottom fertilizer is the most effective measure to increase yield. However, some people think that peanuts have a nitrogen-fixing effect, and they are crops that do not need to be fertilized or do not need to be fertilized, and more fertilizer will cause crazy growth, which is a wrong understanding.

If the amount of fertilizer used in peanuts is insufficient, the nutrients are insufficient, the plants are thin and short, and the flowers and fruits are not much, the yield cannot be increased.

Therefore, the daily planting of peanuts is mainly based on the application of foot fertilizer, supplemented by top dressing or no top dressing.

Peanuts are now mostly mulched and cultivated, top dressing is not easy, you have to open the mulch film at the top or the base of the ridge top dressing, and you have to chase early, you have to chase at the beginning of the flowering period, at the latest can not be later than the peak flowering period, if you chase late, miss the critical period of peanut fertilizer, affect the formation of root nodules, affect its ability to fix nitrogen, and the development of pods, resulting in long growth and late maturity, the gains outweigh the losses.

As we all know, peanuts have a relatively long growth period, and they are very fond of organic fertilizers with long and slow fertilizer efficiency and sufficient fertilizer. Generally speaking, the application of organic fertilizer in peanut land, especially the sandy loam land with low fertility and poor drought resistance must increase the input of high-quality organic fertilizer.

I think it's okay, as long as you give the peanuts enough nutrients to do it.

Personally, I don't think it's possible, because this is not conducive to the growth of metaphysis, and the yield cannot be increased, because when I was young, I planted peanuts at home with base fertilizer first.

Yes, as long as it is given enough nutrients, it is okay to fertilize it at any time.

OK. Doing so allows it to be produced in more quantities and also promotes the reproduction and growth of this food.

Peanut base fertilizer technology

1. How much base fertilizer to apply.

Before stubble removal or ridge formation, 750 to 900 kg of special fertilizer or 300 to 375 kg of three-element compound fertilizer can be applied to peanuts per hectare.

When using single-element fertilizers, 75 to 90 kg of potassium sulfate, 150 to 180 kg of urea or 375 to 450 kg of ammonium bicarbonate and 300 to 375 kg of superphosphate can be applied per hectare.

2. Appropriate amount of watering of the bridge.

For plots with insufficient moisture, splash the ground first to create moisture and pour in an appropriate amount of water to ensure the soil moisture demand of seedlings and seedlings at the seedling stage.

3. Reasonably increase the application of base fertilizer.

When planting peanuts, it is necessary to reasonably increase the bottom fertilizer, and the soil for peanut planting is mostly hilly gravel soil, plain alluvial sandy soil and red and yellow loam soil in the south, this kind of soil texture is sandy, the structure is not very good, and the fertility is relatively low.

In order to ensure the high yield of peanuts, the bottom fertilizer mineral source potassium fulvic acid black gold crystal diluted 300 to 500 kg of water in the field is used to improve the soil, improve the germination rate of peanuts, improve the utilization rate of fertilizer, and promote the fullness of peanut fruits, so as to increase the yield of peanuts per mu.

Types of peanut bottom fertilizer.

1. Nitrogen fertilizer. Peanut roots have rhizobia, which have a nitrogen-fixing effect, which can provide nitrogen elements for plants, and many farmers no longer apply nitrogen fertilizer. But with the progress of planting, the yield of peanuts has also been improved, some plots can reach about 1,000 catties per mu, this kind of peanut plots need a large amount of fertilizer, only rhizobia nitrogen supply can not meet the growth needs, but also need to increase nitrogen fertilizer to solve.

Nitrogen fertilizers commonly used in planting peanuts include urea, ammonium sulfate, ammonium bicarbonate, etc., which are applied as base fertilizers. Urea is a commonly used nitrogen fertilizer on peanuts, generally 20 kg per mu. However, urea cannot be used as seed fertilizer, and it is easy to have rotten seeds and lack of seedlings.

2. Potash fertilizer. Potassium promotes nitrogen uptake and improves plant resistance. The most commonly used peanuts are potassium sulfate and potassium chloride. In the potassium-deficient plots, 15 kg of potassium sulfate per mu was used as the base fertilizer, and the yield increase effect was better.

Potassium sulfate is used in a variety of soils, and some farmers have experienced that the fruit of peanuts turns white after using potassium sulfate. Potassium chloride is used in a much simpler way, and chloride ions inhibit the supply of nitrogen by rhizobia.

3. Calcium fertilizer. Peanuts also have a high demand for calcium when they are grown, surpassing phosphate fertilizers. In the calcium-deficient plots, the rate of peanut rot and empty fruit is relatively high. When excessive nitrogen and potassium fertilizers are applied, it will also affect the absorption of calcium by plants.

The best way is to apply calcium fertilizer to the base fertilizer, which provides calcium at the pod-setting stage, when the calcium is required to the maximum amount of calcium to promote the growth of the pods. Generally, 40 to 50 kg of superphosphate is applied per mu, and phosphate fertilizer is supplemented at the same time, which can be sprinkled during land preparation.

When peanuts are applied to base fertilizer, nitrogen, phosphorus, potassium and calcium are used together, which can not only meet the growth needs of high-yield peanuts, but also save money.

Although the amount of boron, molybdenum and iron is small, it has a great effect, and the effect of base fertilizer or foliar spray is good. Some soils are not deficient in trace elements and can be foliar sprays during the growing period. When there is a serious shortage of fertilizer in the soil, it should be supplemented with base fertilizer, and foliar spraying should be carried out later.

Summary. Hello dear, glad to answer for you! Proper top dressing is required.

Peanuts have rhizobia, and when they reach the flowering and needle stage, rhizobia are gradually formed, and gradually have a certain nitrogen fixation ability, which can provide a large amount of nitrogen to the plant, and until the late growth of peanuts. For plots with good soil conditions and suitable environment, in this ideal state, when it comes to flowering and pod-setting, spraying potassium dihydrogen phosphate aqueous solution can ensure the yield of peanuts.

Hello dear, I'm glad that Yunqinqing has answered for you! Proper top dressing is required. Peanuts have rhizobia, and when they reach the flowering and needle stage, rhizobia are gradually formed, and gradually have a certain nitrogen fixation ability, which can provide a large amount of nitrogen to the plant, and until the late growth of peanuts.

For plots with good soil conditions and suitable environment, in this ideal state, when it comes to the flowering and pod-setting stage, spraying a solution of potassium dihydrogen phosphate next to water can ensure the yield of peanuts.

In the middle and late stages of peanut growth, the number of top dressing should not be too much.

Summary. The biggest nutritional feature of peanut is that there is a root nodule on the root, and there is a symbiotic nitrogen fixation habit, so it can be topdressed according to the symbiotic nitrogen fixation habit, and the peanut root has the effect of nitrogen fixation, but in order to promote the seedling growth period to better grow seedlings, a certain amount of urea can be appropriately applied. In the peanut cluster stage, 7-lo kg of compound fertilizer per mu is topdressed, with 5 kg of urea top dressing.

I wish you a happy life! Hope mine is helpful to you ha<>

Hello dear <>

Peanuts should be properly topdressed. If the soil fertility of peanut is relatively low at the seedling stage, nitrogen fertilizer is the main topdressing, and phosphorus and potassium fertilizer should be applied with the same potato. After the first number of filial piety flowers of peanuts, basal fertilizer and seedling fertilizer should be applied according to the growth of peanuts.

Foliar fertilizer spray is best in the late growth stage of peanut growth and root senescence.

The largest section of peanut is that there is a nodule on the root, and there is a symbiotic nitrogen fixation habit, so the peanut can be topdressed according to the symbiotic nitrogen fixation habit, and the peanut root has the effect of nitrogen fixation, but in order to promote the seedling growth period to grow better seedlings, a certain amount of urea can be appropriately applied. In the peanut cluster stage, 7-lo kg of compound fertilizer per mu is dressed, and 5 kg of urea is used for top dressing. I wish you a happy life!

Summary. Peanuts should not be fertilized.

Peanuts should not be fertilized.

Peanuts still need to be fertilized, especially phosphorus and potassium. Planting peanuts, although rhizobia will fix nitrogen, but also need to fertilize, nitrogen, phosphorus and potassium potato reputation reasonable ratio of the number of eggplant segments. The effect of planting peanut bottom application or top application of peanut special controlled-release fertilizer is good.

Fertilization is required to grow any crop in order to achieve high yield and high efficiency, but it varies according to the fertilizer needs of the crop. Peanuts can be rarely nitrogen-defined, and phosphorus and potassium fertilizers can be applied. Due to the annual planting, the soil fertility decreases, and the elements needed by the plants are lacking, so fertilization is important.

Today's crops need to be fertilized. To grow peanuts, fertilize them, preferably with organic fertilizers. Planting peanuts can be done with some farm fertilizer.

Partial application of n, p, or k is not good. Fertilizer should be applied in a balanced manner according to soil conditions and crop needs.

I'm talking about the location of the fertilization, not directly below the seeds.

Then that's fine, it's okay, planting peanuts and fertilizing them is mainly about improving soil quality.
