What fertilizer is best for growing plastic film peanuts (how to fertilize plastic film peanuts to increase yield)

Is it better to cover or not cover peanuts?

Will covering the peanut field with film definitely result in higher yield than not covering the field with film? The answer is of course it will! Because covering the field with film has many benefits when growing peanuts.

The best temperature for planting plastic film peanuts in spring is when the daytime temperature is stable between 10-15°C, which is between the Qingming Festival and the Grain Rain. If the temperature is not high during the planting of plastic film peanuts, the germination rate of peanuts will be seriously affected.

First of all, let me make it clear that covering the ground with plastic film for planting peanuts is generally for spring peanuts. When planting peanuts in spring, the temperature is relatively low. Covering the ground with plastic film is mainly to increase the ground temperature. As for what fertilizer to use, it is the same as not covering the ground with plastic film. As for what fertilizer is best for peanuts, let's talk about it in detail below!

Principles of fertilizing peanuts covered with plastic film

① Peanut fertilization should be scientific, with organic fertilizer as the main fertilizer and chemical fertilizer as the auxiliary fertilizer;

②Base fertilizer is the main fertilizer, supplemented by topdressing; topdressing is mainly seedling fertilizer, supplemented by flower fertilizer and fruit fertilizer;

③ The basic principle of nitrogen, phosphorus, potassium and calcium application. In addition, peanuts are very sensitive to calcium, magnesium, sulfur, molybdenum, boron and other elements, and these fertilizers are indispensable.

How to fertilize peanuts covered with plastic film to increase yield

① Fertilizer

Peanuts are prone to molybdenum, boron and calcium deficiency, so they can be used as seed fertilizer . Fertilizers can be ammonium molybdate, boric acid or gypsum.

②Base fertilizer

Peanut basal fertilizer is mainly organic fertilizer, supplemented by chemical fertilizer . Generally, 2,000 kg of decomposed organic fertilizer, 5 kg of potassium chloride, 15 kg of diammonium phosphate, and 5 kg of urea are applied per mu of peanuts.

③ Fertilize from seedling stage to before flowering

From the seedling stage to the flowering stage of peanuts, quick-acting nitrogen fertilizer is mainly applied to promote the branching and flowering of peanuts. 4-5 kg ​​of urea and 10 kg of superphosphate are applied per mu, combined with inter-cultivation and soil cultivation .

④ Fertilization during pod-setting period

During the flowering and pod-setting period, peanuts need the most nutrition. The main fertilizer for topdressing is potassium fertilizer, supplemented by nitrogen and phosphorus, to improve the disease resistance of peanuts. Attention should also be paid to the application of trace elements to enhance the growth of leaves, strengthen the photosynthesis of leaves, and increase the accumulation of photosynthetic substances.

For top dressing, you can choose 15 kg of potassium sulfate, 5 kg of urea, or directly choose special compound fertilizer for peanuts. For example, 3 15 or 3 17 special fertilizers. At the same time, spray potassium dihydrogen phosphate + trace element foliar fertilizer on the leaves.

⑤ Fertilization during maturity

Spray potassium dihydrogen phosphate + urea solution on the leaves of peanuts during maturity to prevent premature aging, promote full pod formation, and increase yield. Spray once every 7 to 10 days, and spray 2 to 3 times in succession.

【Summarize】

In general, the selection of base fertilizer for planting plastic film peanuts should focus on the reasonable combination of organic fertilizer and compound fertilizer , but in the later growth and development period, it is also necessary to supplement nutrition through foliar fertilizer. In this way, the quality and yield of peanuts can be maximized.
