What are the precautions for fertilizing peanuts? Keep these points in mind
Peanut cultivation is very common in our country, and the nutritional value of peanuts is very high. When growing peanuts, management work is very important. Fertilization work in particular: reasonable fertilization can provide peanuts with the nutrients they need for growth and is also the key to ensuring healthy peanut growth. However, when fertilizing peanuts, there are many things we need to pay close attention to. So today, the editor has brought you the precautions for fertilizing peanuts. Let's take a look together below!
1. Application of base fertilizer
In the early stage of peanut growth, the number of root nodules is very small, and their own nitrogen-fixing capacity is also relatively poor. After they enter the middle and late stages, fertilizing is no longer suitable after the pegs enter the soil, so applying sufficient base fertilizer is something we need to pay close attention to. Peanut base fertilizer accounts for about 80% of the total fertilizer, and it is also the main method of fertilizing peanuts. The fertilizer is mainly farmyard manure. The more base fertilizer applied, the greater the yield will be. For plots with high soil fertility, the effect of base fertilizer is more obvious. Only by ensuring the application of organic fertilizer can the yield be guaranteed.
2. Pay attention to nitrogen fertilizer
During the growth process of peanuts, the absorption of nitrogen is mainly achieved through nitrogen fixation by the plant's rhizobia. If peanuts lack nitrogen, the leaves are prone to yellowing, and the stems also turn red. This leads to a decrease in the number of rhizobia, causing poor plant growth, and the yield will also decline as a result. However, attention must also be paid to controlling the application of nitrogen fertilizer. If nitrogen fertilizer is applied excessively, it can easily cause peanut vines to grow excessively, leading to lodging in peanuts, which in turn affects peanut yield, and quality will also decline as a result.
3. Balanced fertilization
Balanced fertilization is also something we need to pay close attention to when fertilizing peanuts. When fertilizing, we should pay attention to controlling the proportions of fertilizers such as nitrogen, phosphorus, and potassium, and apply them in a reasonable combination. We should also reasonably match trace element fertilizers such as iron and boron according to soil fertility. This is because peanuts also have a relatively large demand for trace elements during growth. If trace elements are lacking, peanuts are prone to various deficiency symptoms, thereby affecting peanut yield and quality, so everyone must pay close attention to this.
4. Increase the application of calcium fertilizer
Peanut is also a calcium-loving legume crop, and calcium is also very critical to peanut growth. It is very beneficial to the growth and development of peanut roots and root nodules. It can promote the formation of peanut pods and improve their plumpness. At the same time, it can also reduce the rate of empty peanut shells and increase yield. In addition, calcium can also regulate soil acidity and alkalinity, improve the growing environment for peanuts, and enhance the activity of microorganisms in the soil. Therefore, reasonably increasing the application of nitrogen fertilizer is very beneficial to both the yield and quality of peanuts.
The above is a brief introduction to the precautions for fertilizing peanuts. That's all for today's introduction. This article is for reference only, and we hope it can be helpful to everyone!
