What formula is good for peanut fertilizer, and what fertilizer is good for planting peanuts

Peanut fertilization. 30 40 kg of nitrogen, phosphorus and potassium (15 15 15) potassium sulfate compound fertilizer is used as base fertilizer per mu. When seedlings have 2 3 true leaves, apply 8 10 kg of urea per mu to promote seedlings.

Apply 25 30 kg of nitrogen, phosphorus and potassium (15 15 15) potassium sulfate or nitrosulfur-based or pure sulfur-based compound fertilizer plus 10 15 kg of potassium sulfate per mu at the flower bud stage before flowering to promote podding.

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.

Peanut fertilization with basal fertilizer

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.

Peanut fertilizer. Peanuts are a fertilizer-loving plant. The demand for chemical fertilizers is relatively large, and the demand for organic fertilizers, phosphorus and potassium fertilizers is relatively large. When fertilizing at the age of the cover, organic fertilizer and inorganic fertilizer should be used together, and the amount of fertilizer absorbed at the seedling stage of the flower is very small.

Compound fertilizer for peanuts.

Peanuts are a vegetable that can be compounded with fertilizer. First of all, you can make base fertilizer, 10 catties of compound fertilizer per mu. In addition, compound fertilizer can also be used when topdressing, and the specific dosage is 20-25 kg.

Peanut fertilization time.

The fertilization time of peanut was seedling stage, flowering stage, podding stage and maturity stage. Compound fertilizer can be applied at the seedling stage, phosphorus and potassium fertilizer can be used at the flowering stage, potassium fertilizer can be used at the pod-setting stage, and some foliar fertilizer can be sprayed at the maturity stage.

Peanut fertilization methods and tips.

1.Scattering: Peanut fertilization methods mainly include sowing and ditching.

Spreading is to spread the required fertilizer evenly in the ground and then sow the seeds. 2.Ditch Shi:

Furrow application: Dig a soil ditch in the field near the root system of peanuts, then apply fertilizer to the ditch, and then fill the soil to cover it.

Peanuts are familiar to everyone, it is a common crop in our country, almost everywhere has it, will be planted.

But if you want to grow peanuts well, you need to apply good fertilizer.

So, do you know what fertilizer is used for peanut fertilization? How to fertilize peanuts? Let's take a look at it together.

What fertilizer is used for biomimetic fertilization of flower chong, nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, calcium fertilizer, sulfur fertilizer, etc.

The ratio of the demand for nitrogen fertilizer, phosphate fertilizer and potassium fertilizer in the judgment is 1, followed by the demand for several elements such as sulfur and magnesium.

Generally, organic fertilizer is the main fertilizer, supplemented by inorganic fertilizer, and in the case of sufficient organic fertilizer, foliar fertilizer is sprayed according to the growth in the middle and late stages.

How to fertilize peanuts 1, base fertilizer: base fertilizer includes base fertilizer and seed fertilizer, before sowing combined with cultivated land into the fertilizer called base fertilizer, sowing ditch or hole concentrated application of fertilizer for seed fertilizer.

Peanut base fertilizer accounts for more than 80% of the total fertilizer, should be based on organic fertilizer with nitrogen, phosphorus and other fertilizers, the specific application method varies with the type and quantity of fertilization, generally should be dispersed and concentrated combined, most of the land preparation before sowing for bottom fertilizer sprinkling, leaving a small part of the combination of sowing concentrated furrow application or hole application.

In order to improve the efficiency of phosphate fertilizer, phosphate fertilizer and organic fertilizer can be composted for 15 to 20 days before closed fertilization.

Peanut sowing with rhizobia agent can increase the effective rhizobia, in addition, ammonium molybdate or boric acid aqueous solution can be used to supplement the trace elements required by peanuts.

2. Top dressing: according to the growth of peanuts should be timely top dressing, seedling top dressing should be carried out before the first flowering, generally top dressing urea 80 100 kg square kilometers, superphosphate 150 200 kg square kilometers, ditching strips.

After flowering, 300 400 kg of gypsum powder and 150 200 kg of superphosphate can be applied to increase the phosphorus and calcium nutrition in the fruiting period.

In the case of peanut pod-setting and full fruit stage and no topdressing, potassium dihydrogen phosphate and 2% urea can be used for foliar spraying 1 2 times, which can play the role of root preservation and leaf preservation, and improve the seed setting rate and fruit satiety rate.
