What fertilizer is good for growing peanuts? What fertilizer is better to use for growing peanuts

1. Farmhouse fertilizer is a good fertilizer for peanuts.

In the past, when the use of chemical fertilizers was not common in rural areas, farm fertilizers were used. In the past, there were thatched latrines in rural areas, and the mixed farm fertilizer of human manure and plant ash was the first choice for planting peanuts, or the mixed fertilizer of grass ash and poultry manure such as chicken and duck manure. Grass ash is indispensable, and plant ash contains trace elements such as potassium, calcium, magnesium, phosphorus, etc., which is the most needed fertilizer for peanuts.

2. Farm fertilizer.

Only calcium, magnesium and phosphorus are used for planting peanut fertilizer, and there is no need to use different fertilizers at the seedling stage, flowering stage, and pod-setting stage.

Only peanuts will use this fertilizer, and other crops use compound fertilizer or compound fertilizer and nitrogen fertilizer (urea). Nowadays, many people complicate simple things, planting peanuts in rural areas only need to apply foot fertilizer (calcium, magnesium and phosphorus), and apply some base fertilizer calcium magnesium and phosphorus before sowing after ditching, and then basically no more top dressing. If the peanut seedlings grow is caused by too much nitrogen fertilizer, peanuts can not be planted in too fertile soil to avoid peanut seedlings growing.

3. Calcium, magnesium and phosphate fertilizer.

Conclusion: Peanut fertilizer needs calcium fertilizer, magnesium fertilizer, phosphate fertilizer, potassium fertilizer and other trace element fertilizers, avoid nitrogen fertilizer.

In rural areas, peanuts are generally planted in the land with average fertility and loose soil, and the high fertility of the land causes the growth of peanut seedlings and reduces the yield. In the past, only plant ash mixed with human and animal manure was used in rural areas, but now chemical fertilizers such as calcium, magnesium and phosphorus are used.

1. What is the best fertilizer for peanuts?

It is best to apply organic fertilizer to peanuts. In peanut planting, we generally apply organic fertilizers, supplemented by inorganic fertilizers. Among them, organic fertilizers need to be fully decomposed, otherwise peanuts will be infected with pests and diseases.

Inorganic fertilizers are mainly nitrogen fertilizers, phosphate fertilizers and potassium fertilizers, and the mixed application of organic fertilizers and inorganic fertilizers can better promote the growth of peanut plants, improve yield and economic benefits. When planting peanuts, an appropriate amount of decomposed organic fertilizer is applied as the base fertilizer when cultivating the land, and an appropriate amount of nitrogen, phosphorus and potassium compound fertilizer is applied as the seed fertilizer when sowing, and the amount of base fertilizer and seed fertilizer accounts for about 80% of the total amount of peanut fertilization, providing sufficient nutrients for the normal growth and development of peanuts.

Second, how to plant and manage peanuts.

1. Seed selection. When selecting seeds, it is necessary to choose peanut seeds with full grains, no damage, and no pests and diseases. The selected peanut seeds should not only be healthy and full in morphology, but also have strong resistance to diseases and pests and high yields.

The selected peanuts need to be dried for 1 3 days before peeling, and then the kernels are selected after peeling, and high-quality grains are selected as the seeds of peanuts.

2. Watering. Peanuts enter the late stage of development, need to maintain appropriate moisture, generally the appropriate moisture content is about 50 60%. If the weather is dry, the root system is easy to decay, and timely watering is required to avoid the wilting of peanut stems and branches due to lack of water, reduce the satiety rate, and lead to a decrease in yield.

If there is continuous rainy weather, it is necessary to drain the water in time to avoid peanut root rot caused by stagnant water.

1. Organic fertilizer is the main fertilizer, supplemented by inorganic fertilizer: organic fertilizer is full of nutrients, can increase soil aggregate structure, improve soil physical and chemical properties, and is beneficial to rhizobia activities, increase nitrogen, and can reduce the loss and fixation of inorganic fertilizer when used in conjunction with chemical fertilizer.

2. Apply sufficient base fertilizer and appropriate top dressing: organic fertilizer as base fertilizer, in the case of full base fertilizer, according to the growth situation, the appropriate amount of Bika water-soluble fertilizer should be applied in a timely manner, and at the same time, nitrogen, phosphorus, potassium and micro fertilizer should be reasonably matched, and foliar fertilizer should be sprayed according to the growth in the middle and late stages.

Which fertilizer is better for growing peanuts? In fact, the fertilizer suitable for each stage is different, which fertilizer is better for each stage of planting peanuts?

1. Application of boron fertilizer before peanut flowering.

1) Boron is a very important element, "diligent boron lazy calcium", boron plays a very important role in the growth and development of crops. It can promote the carbohydrate operation and protein synthesis in the peanut body, and can make the peanut grow and develop well, with a high pod setting rate, a large amount of fruit, and full grains.

2) Application method: If you use basal boron fertilizer, you can apply it directly when planting peanuts (you must not sprinkle it directly with the seeds to save trouble). If you choose high-purity boron fertilizer that can be sprayed on the foliar surface like Axi, you can choose to spray once at the peanut seedling stage, early flowering stage, and pod stage (the dosage is according to the instructions of the boron fertilizer you choose), and at the same time use it with Trim potassium dihydrogen phosphate, the effect is very good.

2. Sprinkle farm fertilizer before winter and plough the field.

1) This deep ploughing must not be raked, so that the deep ploughed soil will experience winter snow and severe cold, and most of the germ eggs will be frozen to death by turning deep to the ground. The old experience in rural areas is that cultivated land and hoeing are equal to fertilization, which can increase soil permeability, resist drought and protect moisture, and the deep soil also increases the contact area, which can better absorb rain and snow water, and make the land more fertile.

2) The fields treated in this way, directly planting peanuts around May Day, generally do not need to apply any base fertilizer, than those heavy stubble, before the winter did not sprinkle farmhouse fertilizer deep ploughing, but in the spring hastily fertilized and sown peanuts, less chance of disease and insect pests, conducive to healthy growth.

3. The importance of potassium dihydrogen phosphate to peanuts phosphorus and potassium, peanuts are too needed. With the application of boron fertilizer, it can not only provide rich nutrients for peanuts, improve the saturation rate and grain weight of peanut pods, and increase yield, but also realize natural control of prosperity, prevent peanut vine greed, prevent premature aging, and promote most of the nutrients to be directly supplied to pods.

4. Grass ash for increasing production is an old experience of farmers. Because the main element of plant ash is potassium, it naturally has a significant effect on peanut yield after needle, and can also control many pests and diseases. If you want to save money, you don't use potassium dihydrogen phosphate, only plant ash, which is also a good choice.

Common nitrogen, phosphorus and potassium fertilizers and foliar fertilizers such as a spray of green can be used, and the effect is very good.

Priority is given to the special fertilizer for green food that has been recognized by the green food management department. With the autumn land preparation for ridges, apply rotting circle manure, kang hole soil, green manure, etc. Shi 10,000 kg hectares, ridges for ditching, thinning, furrowing for sprinkling.

Ridge cultivation can also be thinned with fertilizer before planting in the year of sowing.

High-yield fertilization technology for peanuts.

1. Suitable soil fertility strip for peanuts.

Peanuts have a wide range of adaptability to soil, but high-yielding peanut fields require good soil conditions. It is best planted on the sandy loam soil under the sand and the solid sandy loam soil on the pine, which can quickly drain water when it rains, and can be quickly irrigated and permeable quickly in drought; The depth of the cultivated layer is about 30 cm. Rich in calcium, the organic matter content is about 1%, more than 2% of the pods are polluted, the quality is reduced, it is suitable to plant new stubble, and the yield is reduced by about 20% in 1 year, which is suitable for rotation with wheat, rice, corn, etc.

Second, the law of peanut fertilizer demand.

The amount of fertilizer absorbed by peanut seedlings is very small, less than 10% of the total, but it is the critical period of nitrogen, phosphorus and potassium fertilizers, and the lack of fertilizer will hinder the early emergence of strong seedlings and the formation of root nodules. The flowering and needle stage of early-maturing peanuts or the podding stage of late-maturing peanuts is the peak period of nitrogen, phosphorus and potassium fertilizers, and the amount of fertilizer absorbed accounts for about 60% of the total. The ripening period and fertilizer amount of full fruit only account for about 10% of the total.

The ratio of nitrogen, phosphorus and potassium absorbed by peanuts is 3::1. However, peanuts rely on rhizobia to supply nitrogen up to 2 3-4 5.

In fact, the nitrogen application level is not high, which highlights the nutritional characteristics of potassium and calcium in peanuts. In addition, peanuts are also sensitive to magnesium, sulfur, molybdenum, boron, manganese, iron, etc.

3. Fertilization technology of peanuts.

1. Basal fertilizer: Peanuts should focus on the application of sufficient basal fertilizer. Generally, 25% lotus amino acid fertilizer 30 40 kg per mu is applied; Or use 16% lotus amino acid peanut special fertilizer 40 to 50 kg.

2. Top dressing is generally used for wheat set peanuts or summer peanuts with insufficient base fertilizer. Apply 16% or 18% lotus amino acid fertilizer 30 40 kg per mu at the early flowering stage of peanuts;

3. Foliar fertilization should consider the application of iron, boron, manganese and other micro-fertilizers on the northern alkaline soil with strong calcareous nature; Attention should be paid to the application of molybdenum, boron and other micro-fertilizers on the acidic soil in the south of the rainy area. The amount of foliar fertilizer spray is small, easy to apply, and the effect is good; With lotus amino acid foliar fertilizer (peanut special), 300 500 times in the early flowering period, foliar spraying 2 3 times, combined with the prevention and control of leaf spot disease, mixed with fungicides, can achieve twice the effect with half the effort, that is, supplementing the micro-fertilizer, and preventing and controlling the disease.

It is better to use potassium fertilizer for peanuts. Noisy limbs

Peanut fertilization method

1. The absorption of nitrogen, phosphorus and potassium and the proportion of fertilizer required by peanut.

Generally, for every 100 kg of peanut fruit produced, nitrogen needs to be absorbed from the soil to kilograms, phosphorus pentoxide to kilograms, potassium oxide to kilograms, and the ratio of nitrogen, phosphorus and potassium is 1 to 0 ratio: to about 1:0, the higher the peanut yield, the higher the absorption of nitrogen, phosphorus and potassium.

Second, the principle of peanut fertilization.

Peanuts are formulated with nitrogen, phosphorus and potassium. The formula ratio is 1 ratio, the principle of fertilization is to base fertilizer, timely top dressing, base fertilizer to organic fertilizer, with phosphorus, potassium fertilizer, top dressing seedling stage to the appropriate amount of available nitrogen fertilizer, the general bottom fertilizer accounts for more than 80% of the total amount of fertilizer.

3. Peanut fertilization method.

1) Base fertilizer and seed fertilizer: peanut base fertilizer accounts for 80% to 90% of the total fertilizer, mainly organic fertilizer, with nitrogen, phosphorus and other chemical fertilizers. The exact application varies depending on the amount and type of fertilizer applied.

Generally, it is a combination of dispersion and concentration, most of which are used for base fertilizer before sowing, and a small part is left in combination with sowing concentrated furrow application or hole application.

2) Fertilization requirements: 2500 to 5000 kg of organic fertilizer, 10 kg of urea or 15 kg of diammonium, 4 to 6 kg of potassium dihydrogen phosphate per mu, and the use of long-lasting compound fertilizer is advocated, 30 to 50 kg per mu. In order to comprehensively improve the level of fertilization, to achieve the purpose of sufficient and balanced fertilization.

1. Apply farmhouse fertilizer.

1. Farm fertilizer: If you grow peanuts at home, in order to ensure that the peanuts are greener, it is best to apply farm fertilizer, that is, animal manure, including pig manure, chicken god manure, etc., it should be noted that when applying farm fertilizer, we must ensure that the fertilizer is fully rotted.

2. How to ferment: Farmhouse manure is generally fermented by composting, that is, the farmhouse manure is piled on the ground, and a layer of soil is covered on the compost to prevent insects from laying eggs.

3. How to apply: farmhouse fertilizer can be used as base fertilizer and top dressing, before planting peanuts, that is, when preparing the land, farm fertilizer will be used as base fertilizer, mixed into the soil of planting peanuts, and then with the growth of peanuts, farm fertilizer can be applied several times as top dressing.

Second, the application of chemical fertilizers.

1. Chemical fertilizer: If you plant peanuts in the earth, in order to sell the peanuts, it is best to apply chemical fertilizers, the most commonly used of which are urea and superphosphate, which are used as fertilizers to supplement nutrients for peanuts.

2. How to apply: Before deep ploughing and land preparation, mix urea and superphosphate into the soil, supplement nitrogen fertilizer and phosphate fertilizer for the plants, and prepare a small amount of plant ash by the way, compensate for potassium fertilizer for the plants, and then carry out top dressing as appropriate with the growth of the plants.

Fertilization is essential in the process of growing peanuts, and generally speaking, only applying enough fertilizer to peanuts can promote their good growth and also improve peanut yield and quality.

When planting peanuts, it is best to apply organic fertilizer, such as farm fertilizer, that is, animal manure, including pig manure, chicken manure, human manure, etc., but it should be noted that when applying farm fertilizer, it must be ensured that the fertilizer is fully decomposed, otherwise it will harm the plant and affect its growth.

Plant peanuts with fertilizer to increase yield.

If you want to increase the yield when planting peanuts, you can mix kilograms of peanut rhizobia agent with seeds per mu of peanuts, or you can mix gram molybdicic acid, and mix gram boric acid per kilogram of seeds to plant, which can improve the yield.

Planting flowers talks about annihilation, fertilization, and more flowering.

Planting peanuts to promote Kao No. 3 can produce more flowers, because it can promote the flower bud differentiation of the plant, and has a good effect on promoting the early prosperity of branches and increasing the number of flowers and pods.

Peanut fertilization time.

Generally speaking, there are three times for fertilizing peanuts, the first is general application of basal fertilizer, the second is before flowering, and the third is the pod stage.

Peanut fertilization method

Basal fertilizer: basal fertilizer includes basal fertilizer and seed fertilizer, before sowing combined with cultivated land application fertilizer is called basal fertilizer, sowing ditch and opening concentrated application of fertilizer is called seed fertilizer, generally speaking, most of the base fertilizer is applied before sowing to the front, and a small part is combined with sowing concentrated ditch application and hole application.

Top dressing: according to the growth of peanuts in a timely manner, seedling top dressing should be carried out before flowering, generally add urea 80 100kg square, superphosphate 150 200kg square, ditch application.

1. Peanut fertilization is mainly based on base fertilizer, which can account for 70% 80% of the total amount of fertilizer, generally about 2 tons of high-quality manure per mu, 50 kg of cake fertilizer, and 4 kg of nitrogen, 7 kg of phosphorus and 7 kg of potassium. When applying, the coarse fertilizer is used as the base, the fine fertilizer is covered, the fertilizer and soil are mixed evenly, and the fertilizer is separated from the seeds, so as not to harm the seeds.

2. The topdressing of peanuts should be determined according to soil fertility and growth. Generally, when plowing and weeding after the seedlings, see the seedlings apply seedling fertilizer once, and use about 3 kg of urea per mu to water the water. If the basal fertilizer is sufficient, the seedling fertilizer can also be omitted.

3. Peanuts should be topped with heavy fertilizer at the first flowering stage, 3 kg of urea, 5 10 kg of phosphate fertilizer, and 3 5 kg of potassium chloride per mu, which should be applied before the first flowering.

4. For calcium-deficient soil or acidic soil, 50 kg of lime can also be applied at this stage to meet the calcium needs of peanut pods.

5. Spraying ammonium molybdate solution at peanut seedling stage and full flowering stage can promote root nodule nitrogen fixation, and spraying plants with borax solution at early flowering and full flowering stage can improve peanut fruiting rate and seed setting rate. Spraying potassium dihydrogen phosphate in the full flowering period of peanuts can promote the expansion of pods and improve quality.
