When to hit the foliar fertilizer of peanuts?

Peanut is a common crop, many areas make money by growing it, and if you want peanuts, you have to apply good fertilizer. When will peanut foliar fertilizer be hit?

1. Seedling stage

Peanut seedlings are mainly growing seedlings, at this time, it is recommended to supply nitrogen fertilizer, although phosphorus and potassium fertilizer is also very important, but at this stage, the nutritional consumption of these is really small, more consumption of nitrogen fertilizer. You can consider nitrate nitrogen fertilizer such as ammonium nitrate or ammonium chloride or ammonium nitrogen fertilizer, of course, potassium nitrate is also a good choice.

2. Flowering period

Peanut has a decreased demand for nitrogen fertilizer at flowering stage, and its own nitrogen fixation ability is strong, so it is no longer necessary to supplement nitrogen fertilizer, and some phosphorus and potassium fertilizer can be added appropriately. Phosphorus plays an important role in the growth and development of peanut root and nodule. At the same time, potassium fertilizer can also promote flowering and prevent lodging. However, at this time, only phosphorus and potassium fertilizer supply is still slightly insufficient, scientific Xingnong suggested that peanut supply of some trace elements, zinc (Zn) and iron (Fe) elements can increase yield and prevent disease.

In summary, we can consider supplying some foliar fertilizers such as potassium dihydrogen phosphate + zinc sulfate + ferrous sulfate and so on. Of course, there are also specially sold trace fertilizers, which can be used together with potassium dihydrogen phosphate to increase production and disease resistance.

3. Podding and expansion period

Potassium dihydrogen phosphate can be sprayed during the pod expansion period, which can promote the demand of pods for phosphorus and potassium fertilizer, and greatly improve the potassium fruits and vegetables and fruit plumpness of peanuts.

It should be noted that spraying foliar fertilizer must pay attention to control the concentration, must follow the instructions, and do not blindly increase the dosage. And when spraying, we should also pay attention to the weather and spraying time to avoid futility.
