Time and method of fertilization for Peanut

Peanuts are widely used in our country, which is not only a small snack in our daily life, but also a basic raw material of edible oil in our country. Now the planting area of peanuts in our country is very extensive, and topdressing is essential when planting peanuts. So when should we fertilize peanuts? How to apply fertilizer exactly? The following editor will introduce you one by one, let's have a look!

1. Seedling stage

In the seedling stage of peanut, the demand for nutrition is relatively small because the root nodule is not fully developed. As long as sufficient base fertilizer is applied before sowing, the growth nutrition can be satisfied, and the growth rate will be improved. At this time, proper topdressing of compound fertilizer can ensure the normal growth of peanuts, but we should pay attention not to apply too much phosphorus and potassium fertilizer, otherwise it will have a bad effect on the seedlings. If the basal fertilizer is insufficient in the seedling stage, it should be applied in time before the first flowering, mainly nitrogen fertilizer, and the main fertilization methods are sprinkling and furrow application.

2. Flowering period

The nutrition consumption of peanut in flowering period is relatively large, because during this period, the growth direction of peanut will gradually change to reproductive growth. Its nutritional demand will also increase sharply, so it is necessary to topdressing in time during this period to ensure that there is sufficient nutrition to promote peanut flowering. At this time, the proportion of nutritional requirements of peanuts is mainly phosphorus and potassium fertilizer. And because peanuts have nitrogen fixation capacity, so appropriate supplement of phosphorus and potassium fertilizer, do not apply too much nitrogen fertilizer, otherwise it is very easy to lead to peanut growth and reduce yield. In addition, if it is found that the flowering rate of peanuts is low, it may be caused by boron deficiency, so boron fertilizer should be applied properly.

3. Podding period

When the peanut is in the podding stage, the nutrition needed for its growth is the most exuberant, and its demand and consumption are the largest in the whole growth period. Therefore, it is necessary to supplement a lot of nutrition at this time to promote the growth of pods and increase the yield. During this period, the main fertilizer of topdressing was potassium fertilizer, supplemented by nitrogen and phosphorus, to improve the disease resistance of peanut. And we should also pay attention to the application of trace elements, enhance the growth of leaves, strengthen the photosynthesis of leaves, and increase the accumulation of photosynthetic substances. It can not only ensure the growth of pods, but also prevent premature senescence.

4. Mature period

When the peanut pods gradually mature, the demand for nutrients will slowly decline, so the nutrient absorption capacity will gradually weaken. However, there is still a certain demand for nitrogen, phosphorus and potassium, and there is a high demand for nitrogen fertilizer in the mature stage. Reasonable fertilization can improve the resistance of peanut to diseases and insect pests. To prevent the occurrence of empty fruit, rotten fruit and other bad phenomena. Foliar nitrogen fertilizer can be properly sprayed, and its utilization rate can reach about 60%, which is also very effective in promoting pod ripening. However, we should pay attention to control the dosage, do not apply fertilizer blindly, otherwise it is easy to backfire.

The above is a brief introduction of the time and methods of peanut fertilization, peanut fertilization is very important in the whole growth period, if improper fertilization, the impact on peanuts may be irreparable.
