When planting peanuts, how to use plant ash scientifically?

Use plant ash in the peanut needle stage.

Peanut needle period is the key stage of peanut fruit formation, peanut needle period reasonable fertilization can promote flowering, but must be combined with the actual growth of peanut reasonable fertilizer. If the peanuts are growing normally at this time, then you can sprinkle the plant ash into the peanut field or ditch the 10 cm side of the peanut root, cover it with soil and water it.

The main component of plant ash is available potassium fertilizer. Appropriate amount of potassium fertilizer can improve the photosynthesis of peanuts and promote the healthy growth of peanuts. Regulate the opening and closing of leaf stomata and cell osmotic pressure, and improve the ability of peanut to resist disease, drought and waterlogging. Potassium fertilizer should not be excessive, otherwise it will inhibit the absorption of calcium and magnesium.

The peak potassium requirement of peanut is at the flowering and needle stage and pod expansion stage. At the seedling stage, plant ash and nitrogen fertilizer should be applied as basal fertilizer, and it is best to apply furrow. Appropriate amount of topdressing and watering at the flowering needle stage is conducive to nutrient absorption.

The plant ash is covered with peanuts, which can keep the peanuts warm and keep them from cold when it rains.

Summary. The use of plant ash: in the peanut (pod expansion period), mix 200 kg of water with 10 kg of plant ash, stir evenly, after half a day of standing, filter out the slag of plant ash, and spray the plant ash leaching solution on the peanut.

When planting peanuts, how to use plant ash scientifically?

The use of plant ash: Qin Qin in peanuts (pod swelling period), with 200 catties of water with 10 catties of plant ash, stirring which mix evenly, after half a day of standing after the completion of the attack, the slag of the plant ash is filtered out, and the plant ash leaching solution is sprayed on the peanuts.

In order to achieve the best effect of the grass and wood key ash, under normal circumstances, it is necessary to spray the plant ash leaching solution on the peanut about 2-3 times, and the interval between each time is about a week.

1. When should peanut fertilizer be applied?

1. The law of fertilizer demand.

For every 100kg of peanut pods produced, nitrogen, phosphorus, potassium, and calcium are required, and the ratio is nitrogen:phosphorus:potassium:calcium = 5:1:3:2.

2. Fertilization technology.

1) Base fertilizer. Apply 1000-1200kg of decomposed farm fertilizer, 5-10kg of ammonium sulfate, 15-25kg of calcium-magnesium phosphate fertilizer, and 5-10kg of potassium chloride per mu. Two-thirds of them are applied to a depth of 30 cm and one-third to a layer of 10-15 cm.

2) Seed fertilizer. Use 1000kg of decomposed organic fertilizer, 5-10kg diammonium phosphate mixed furrow application or hole application. At the same time, before sowing, peanut rhizobia agent and 10-25g ammonium molybdate were used for seed dressing per mu.

3) Top dressing. > is mostly used for summer peanuts or intercropping peanuts with insufficient basal fertilizer application. Before the first flowering of peanuts, 500-1000kg of decomposed organic fertilizer, 4-5kg of urea, 10kg of superphosphate are applied per mu, or in the middle and late stages of peanut growth, foliar spraying 2-3 times of soil chef polymerized potassium dihydrogen phosphate + 2% urea mixed fertilizer.

Yes, plant ash can be used as base fertilizer, seed fertilizer and top dressing, and sprinkled into the soil can eliminate pests and viruses, and prevent the occurrence of diseases such as blight, powdery mildew and root rot. Spraying plant ash leachate on the leaf surface can control aphids, red spiders and other insect pests.

Peanut planting management.

1. Choose peanuts with full grains and peel them, soak the peanuts in water or mix them with medicine for later use 2. Dig a small pit with a hoe, put two or three peanuts into each pit, and then cover the soil. (Of course, now it's all machine-seeding).

3. Fertilize and hoe the soil.

When the flowers grow seedlings, the compound fertilizer and phosphorus fertilizer are sprinkled next to the peanut ridge, and the fertilizer is covered with a hoe, and the peanut soil is cultivated at the same time, and the trime potassium dihydrogen can also be used.

4. After half a month, hoe for the second time, sprinkle in the ashes of the grass and trees, then hoe the ground, and pull the grass at the same time.

5. Flowering needle is to hoe the soil again, which is convenient for peanuts to stick needles and set fruits, and at the same time remove weeds.

1.Overview of peanut grass ash.

Peanut plant ash is rich in potassium oxide, calcium, magnesium and trace elements, and is a natural organic fertilizer. It can also regulate soil pH, promote plant growth, and improve crop quality and yield. Because it effectively reduces the use of chemical fertilizers, it is increasingly favored by farmers.

2.How to use:

There are many ways to use peanut plant ash. First of all, mix peanut grass ash in the soil, mix well, then dig a small pit around the plant, pour it into the soil, gently pat the top layer of soil, and then water it appropriately. Secondly, peanut grass can be used for seed preparation, plant planting and land preparation and fertilization.

3.Plants suitable for the use of peanut grass ash.

Peanut plant ash is suitable for the growth and fertilizer supplement of various crops such as fruit trees, vegetables, wheat, rice, etc. It is especially suitable for nutrient-rich germination crops, and the use of peanut plant ash can promote the growth of these crops, as well as benefit the harvesting and storage of crops.

4.Precautions.

Attention should be paid to the amount of peanut plant ash, too much will lead to soil salinization, too little will have no obvious effect. When using, attention should be paid to mixing and mastering the wetness of watering, so as not to cause concentrated rot in the roots of plants. Peanut plant ash is best mixed with other organic fertilizers to get better results.

5.Let the peanut grass ash say goodbye to abandonment.

Waste peanut ash can also be reused to make new organic fertilizers. For highly acidic or salty soils, waste peanut plant ash can be mixed with other organic fertilizers, and finally applied to the soil, which can play a good role in improving soil pH.

6.Advantages of using peanut plant ash.

The advantage of using peanut plant ash is that it is natural, non-toxic, safe and environmentally friendly. It is rich in organic matter and also has a good revitalizing effect on the soil. In addition, this fertilizer is easy to use and can promote healthy plant growth, enhance the plant's natural resistance, and improve the quality and yield of the plant.

7.Benefits of using peanut grass ash.

The use of flower and cave raw plant ash has good economic and social benefits. When farmers use chemical fertilizers, due to their high cost per mu, the operating benefits are limited, and at the same time, it will lead to environmental problems such as soil pollution. The use of peanut plant ash instead of chemical fertilizer can not only improve the yield and quality of crops, but also ensure ecological security and promote the sustainable development of agricultural production.

It is not recommended that the contact between the ash and nitrogen fertilizer can easily cause nitrogen volatilization loss. Because the peanut is a crop that coexists with nitrogen-fixing bacteria, the demand for nitrogen fertilizer is large, and the rhizobia powder can be selected for seed dressing, and 25g of rhizobia powder is added to the seed amount per 667 square meters, and the fungus powder is mixed into a bacterial solution with 100 150ml of water, and it is evenly mixed on the seeds.

During the peanut mulching to the emergence of the seedling, when it is found that the film is broken or the coverage is not tight, it should be used in time to re-bury and plug tightly. When the seedlings break through the membrane arch soil and begin to expose the true leaves, the soil on the membrane is removed to expose the cotyledons to the surface. If a hole is found, immediately replant it with seeds that promote germination.

Before flowering, 1 tillage and weeding was carried out in the furrow. During the period from flowering to pod fullness, according to the flower growth potential, the foliar spray of Trim potassium dihydrogen phosphate 800 times solution 2 3 times, or, and spray Zhuangtilin to increase the amount of nutrient delivery, promote fruit development, and improve the yield of peanuts. During this period, in case of drought, it is necessary to irrigate in time.
