What kind of peanuts have a high yield, and how to grow peanuts with a high yield

In order to further improve the yield of summer-sown peanut, the scientific method of fertilization was summarized in practice, which could not only increase the yield of peanut, but also scientifically use the fertilizer source.

1. Early nitrogen application. Peanuts absorb a large amount of nitrogen, and generally 3-kg of pure nitrogen is required to produce 50 kg of pods. In fact, peanuts themselves have rhizobia symbiosis, and 80% of the nitrogen required is fixed by rhizobia.

After peanut enters the seedling stage, the nitrogen in the seeds is basically used up, and the nitrogen fixation ability of rhizobia on the root system of the seedlings is very weak, so the early supplementation of fast-acting nitrogen fertilizer is not only conducive to cultivating strong seedlings, promoting the differentiation of flower buds in the early stage, but also can play a role in promoting the development of rhizobia. Generally, 3000 kg of high-quality rotting farmhouse fertilizer and 5 kg of urea are used as base fertilizer per mu, and the time of applying seedling fertilizer should not be later than the flowering and needle period, and it should not be too much.

2. Sufficient phosphorus: although peanut absorbs less phosphorus, phosphorus is very important for peanut growth and development, and phosphorus fertilizer can not only effectively enhance the nitrogen fixation ability of rhizobia in the process of peanut growth, but also significantly promote the reproductive growth of plants, and improve the quality of peanuts. The peak period of phosphorus requirement of peanut is mainly before the podding stage, so sufficient phosphorus fertilizer should be applied in the early stage, and it is appropriate to apply 12 kg of superphosphate per mu.

After sealing the ridge, if the phosphate fertilizer is insufficient, you can spray 3% superphosphate solution, spray once every 7-10 days, and spray 2-3 times in a row.

3. Skillful supplementation of molybdenum and calcium: peanut is a crop that likes calcium very much, and the role of calcium is mainly to promote the development of pods and the formation of peanut kernels, which has a great impact on yield and quality. Calcium fertilizer is better with gypsum, and the dosage per mu is about 20 kg.

When applied, the gypsum is ground into a fine powder, and applied when the peanut is in full bloom and most of the fruit needles are in the ground. If the peanut tree grows too vigorously, you can use your feet to step on the peanut seedlings, which can not only prevent the seedlings from growing vigorously, but also help the fruit needles to be pricked. At the same time, peanuts also need molybdenum.

The role of molybdenum is to promote nitrogen fixation by rhizobia and the utilization of nitrate nitrogen by peanut. Commonly used molybdenum fertilizers mainly include ammonium molybdate, sodium molybdate, etc. It is used by seed dressing, soaking and foliar spraying.

Such as seed dressing, 90-225 grams of ammonium molybdate are weighed per hectare of peanuts, dissolved in warm water with a small amount of 35-40 degrees Celsius, and then the solution prepared by kilograms of water is directly sprayed with a sprayer, sprayed and mixed at the same time, and can be sown after drying. Such as soaking seeds. Each hectare of peanuts weigh 225-375 grams of ammonium molybdate, kilograms of water, prepared into a solution, and then soak the seeds, soak for 3-5 hours, and then sow after fishing.

Such as foliar sprays. Spraying concentration, spraying liquid per hectare of 750 kg, can only be sprayed at the seedling stage or flowering stage, can also be sprayed at the seedling stage, flowering stage each once sprayed, the latter effect is good. The application of molybdenum fertilizer must strictly control the dosage, such as exceeding the specified standards, not only has a certain impact on peanut germination, but also easy to cause heavy metal molybdenum pollution to peanuts and the environment.

Peanuts can be grown with high yields by cultivating soil and applying foliar fertilizer.

During the planting process, we need to carry out appropriate soil cultivation according to the softness of the soil and the growth rate of the plants. Cultivating can make the soil softer, improve the permeability of the soil, strengthen the respiration shelter of the roots, make the nutrient absorption more comprehensive, and promote the growth of peanuts.

Foliar fertilizer is very important for peanuts, and the application of foliar fertilizer can not only provide water for leaf growth, but also promote leaf growth rate, enhance photosynthesis, and increase nutrient accumulation within the plant. However, it is not possible to blindly apply foliar fertilizer, if it is not used properly, the leaves may not be too hypertrophied, affecting the light of the plant, and it will have a certain impact on the vertical length of the plant.

Precautions for peanut planting

Choose the right peanut variety according to the climate and soil conditions of the growing area. Different varieties have different adaptability to environmental conditions, and selecting the right varieties can improve yield and resistance to pests and diseases. Peanuts prefer loose, fertile soils.

Before planting, soil tilling and weed removal are carried out to ensure that the soil is well drained and rich in organic matter. Peanuts are suitable for sowing in seasons when temperatures are stable. Depending on the local climatic conditions, choose the right time to sow seeds, usually in spring or summer.

In the process of peanut growth, proper fertilization is very important. Depending on the soil quality and the growth needs of the peanuts, appropriate organic and mineral fertilizers are applied. Take care to avoid over-fertilization to avoid causing harm to the plants.

Peanuts are susceptible to some viruses, fungi, and pests. Regularly inspect peanut plants, detect and deal with pests and diseases in a timely manner, and take appropriate control measures, such as spraying biological pesticides or using chemical pesticides rationally.

The above content refers to the encyclopedia - peanuts.

The cultivation methods for high peanut yields are as follows:

1. Neutral soil is the best. Acid-base adjustment is carried out, so that it is suitable for the growth of peanuts. Deep ploughing is also required to keep the soil loose.

2. It is best to choose excellent seeds on the market. Medicate the seeds in advance to prevent pests and diseases in the orange soil and ensure that the peanut seedlings are rooted.

3. Keep sufficient water and fertilizer to ensure the growth and flowering of peanut seedlings.

4. Pay attention to pest control, mainly from seedling stage to early flowering stage, flowering period to pod-setting stage and podding stage to fruit expansion stage.

Peanuts should be in sandy soil areas with a warm climate, a long growing season and moderate rainfall. Nitrogen application should not be too much during the seedling shortage group period. Deep ploughing and deep ploughing are conducive to the growth and development of peanuts.

If you want to improve the yield of peanuts and corn, pay attention to a few points: 1. Choose high-quality and high-yield seeds, and soil disinfection are important measures to effectively improve the yield. 2. It is best to choose the land that has not been planted with legumes, and the soil should be loose and well-drained sandy loam soil, and the soil should be neutral and planted.

3. Generally, choose a suitable temperature for sowing in spring, ridge the land, ridge spacing 50 cm, hole spacing 15 16 cm, and then sow two seeds per hole, water, and cover with soil after sowing. 4. After germination, pull out weeds and fertilize in time, and do a good job in the prevention and control of pests and diseases.

In the peanut flowering stage and pod stage, according to the dosage of 50 kg of water + 50 grams of ammonium molybdate per mu, spray 1-2 times continuously, and spray once every 7-10 days, which can make the pod grains of peanut develop more full and full, and generally can achieve more than 10% increase in yield.

The method of improving peanut yield is very simple, the key is to add scientific and correct methods with heart, the following will introduce you to some methods to improve the production and quality of flowers, I hope it will be helpful to you.

1. Sowing seeds in the shell.

Sowing seeds with shells can make the peanut shells gradually decay in the ground, promote the absorption of nutrients by the roots, create better ventilation conditions for the soil of the root system of the peanut, and maintain the internal water demand of the peanut. In contrast, grown huskless peanuts grow slowly. The seedling stage of shelled peanut is at least 3 5 days earlier, and the seedlings are strong and leafy.

The green leaves in the later stage can greatly improve the fruit setting rate, making the pods fuller, more concentrated and easier to harvest.

2. Germination. Taking measures to promote peanut germination by soaking seeds can shorten the seedling emergence time of peanut, avoid the problems of rotten seeds and lack of piles in the later stage, and improve the seedling emergence rate. Studies have shown that germination at least a week earlier than non-sprouted peanuts significantly increases emergence (about 16%).

Specific method: After the peanut is dried, soak it in 35 warm water for 12 hours, drain the water, put it in the straw basket to buy, keep it at a temperature of 20 30, place it for 36 hours, and germinate after sowing.

3. Autumn peanut planting.

Autumn peanut seeds have a lower fat content than spring seeds, and many seeds contain hydrophilic starch and protein.

After sowing, it absorbs water and has a high respiration intensity, which can promote seed germination. At the same time, the autumn storage temperature of peanut seeds is low, the storage time is short, the possibility of seed mildew is small, and the germination rate, antibacterial ability and seedling emergence rate of peanut seeds are not high, which will greatly improve their germination rate, antibacterial ability and emergence rate.

Fourth, add gypsum.

The scientific use of gypsum in the peanut planting industry is conducive to improving the soil, promoting the increase of calcium content in the core layer, and improving the seed setting rate and seed yield. The results showed that the average yield of peanut per mu could be increased by 25 35 kg by 25 35 kg with 667 m2 as the standard. In addition, gypsum is more effective than basal fertilizer.

Spraying gypsum on the fruit circle after peanut flowering can effectively improve the quality and yield of peanut. Soil tillage and needle tillage can be divided into two periods.

The first time: 4 5 days before peanut flowering, put the first pair of peanut side branches on the first root, two fruit needles buried in the soil, and wait for the second side branch fruit needles to just grow a deep hoe nest, which can improve the fruit setting rate of side branches.

The second time: before and after Shenghua, the use of high soil can ensure that the needles in the middle and late stages of the high section can be quickly buried in a short time, and the thickness of the soil layer can be controlled at about 3 cm.

Sowing seeds in the shell, stepping on the seedling cover needle, removing the main stem, peanut topping, fertilization methods, and fertilization types can all improve peanut yield.

Choose the right variety of planting, so that you can better plant the Lingchen tung planting, a foot of calm to pay attention to the planting link, pay attention to the planting conditions, so that you can better complete the planting, pay attention to watering, pay attention to fertilization, pay attention to the use of fertilizer. Brother.

First of all, we should choose high-quality varieties, and secondly, we should water and fertilize in a timely manner, strengthen the management of water and fertilizer, ensure that the light is sufficient, spray pesticides regularly, remove insect pests in time, pay attention to temperature control, and then we should also relax the soil in time, maintain the permeability of the soil, and do a good job in drainage and ventilation.

6.Shennong peanuts: a special product of Jiaozuo City, Henan Province, China, with high yield, good quality, high oil content and unique flavor.

Stepping on the seedling cover needle, a large number of flower needles will be formed during the flowering period of peanuts, and the flower needles will form pods when they enter the soil. It can be used to step on seedlings or cover soil to improve the penetration rate of flower needles, so as to increase the yield of peanuts.

The first point is that peanuts are like that special brand, then they will definitely have a high yield, and the second point is that farmers can graft and manage them when planting, which can improve the yield.

It is necessary to choose the right variety according to the local environment, and when planting, you must pay attention to the surrounding environment, pay attention to watering, and pay attention to fertilization.

The yield per mu of peanuts can generally reach 300 kilograms, and the high-yield fields can be close to 400 kilograms.
