Peanut planting technology: symptoms and control methods of phosphorus deficiency in peanut

When I met Liu, I asked a question, will you still plant peanuts next year? Why did you ask this question? It turned out that Liu Da Ge and the old man of the same village had contracted a piece of land to plant early peanuts in the village. I didn't think that the Peanut plants were not only short, branching, but also the leaves were not shiny. Wang Laotou was still fainted and lived in the hospital. What happened to the hospital?

When I saw it in the ground, I found that, like Liu`s big brother, the peanuts were short, the leaves were dull and the red and red lines appeared on the lower leaves and stem base. This is a typical lack of phosphorus. Today, Kobayashi will share the symptoms and prevention methods of sharing phosphorus deficiency in peanuts.

First, what are the symptoms of phosphorus deficiency?

(1) When phosphorus is deficient, peanut growth will stagnate, leaves will be dark green; lower leaves and stems will be purplish red. Seedlings will be severely deficient in the spring and cold seasons; however, as the climate warms, the roots gradually expand and the phosphorus deficiency will gradually disappear.

(2) In the absence of phosphorus, the plants are short, the roots are poorly developed, the secondary roots are few, and the base of the stems is red.

Second, the importance of phosphorus

Phosphorus is an essential component of genetic material and participates in the metabolism of plants. It plays an important role in photosynthesis, protein formation and oil conversion. When the phosphorus supply is sufficient, it can promote the development of peanut roots and improve the resistance of peanuts to adverse environments.

Third, how to do peanut deficiency

10 to 15 kg of calcium phosphate per acre or 25 to 100 kg of phosphate rock powder can be used as base fertilizer, seed fertilizer or top dressing. When mixed with nitrogen fertilizer, the application effect is better.

Liu Da Ge will plant peanuts next year, and certainly will not let the peanuts lose phosphorus. This is really a deep experience. So in order to prevent the occurrence of this symptom of peanut planting, everyone must carefully read this article!
