A Detailed Guide to the Correct Timing and Methods of Fertilizing Peanuts
Peanuts are used very widely in China; they are not only a everyday snack in our daily lives, but also a basic raw material for our country's cooking oil. At present, China's peanut planting area is very extensive, and when growing peanuts, the work of topdressing is indispensable. So when should peanuts be fertilized? How exactly should they be fertilized? Below, the editor will introduce them one by one for everyone. Let's take a look!
1. Seedling stage
During the peanut seedling stage, because its root nodules have not yet fully developed, its demand for nutrients is relatively small. As long as sufficient base fertilizer is applied before sowing, the nutritional needs for growth can be met, and the growth rate will also be increased. At this time, properly applying compound fertilizer as a topdressing is enough to ensure the normal growth of peanuts, but note that too much phosphorus and potassium fertilizer must not be applied, otherwise it will instead have adverse effects on the seedlings. When fertilizing at the seedling stage, if the base fertilizer is insufficient, then it should be applied promptly before the beginning of flowering, mainly with nitrogen fertilizer, and the fertilization methods are mainly broadcasting and furrow application.
2. Flowering stage
The nutrient consumption of peanuts during the flowering stage is relatively large, because during this period the growth direction of peanuts will gradually shift to reproductive growth. Their nutritional needs will also increase sharply, so at this time topdressing must be done promptly to ensure sufficient nutrients to promote peanut flowering. At this time, the proportion of peanut nutritional needs is mainly phosphorus and potassium fertilizer. And because peanuts have nitrogen-fixing ability, it is enough to properly supplement phosphorus and potassium fertilizer; too much nitrogen fertilizer must not be applied, otherwise it is very easy to cause excessive vegetative growth of peanuts and reduce yield. In addition, if it is found that the flowering rate of peanuts is low, then it may be caused by boron deficiency, so boron fertilizer should also be properly applied as a topdressing.
3. Pod-setting stage
When peanuts are in the pod-setting stage, it is the period when the nutrients required for their growth are most vigorous, and their demand and consumption are the greatest throughout the entire growth period. Therefore, at this time, a large amount of nutrients should be supplemented to promote pod growth and increase yield. During this period, 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 leaf growth, strengthen leaf photosynthesis, and increase the accumulation of photosynthetic substances. This can both ensure pod growth and prevent premature aging.
4. Maturity stage
After peanut pods gradually mature, the demand for nutrients will slowly decline, so the ability to absorb nutrients will also gradually weaken. However, there will still be a certain demand for nitrogen, phosphorus, and potassium elements. During the maturity stage, the demand for nitrogen fertilizer is relatively high, and reasonable fertilization can improve the resistance of peanuts to pests and diseases. Prevent undesirable phenomena such as empty pods and rotten pods. Foliar nitrogen fertilizer can be properly sprayed, and its utilization rate can reach about 60%, which is also very effective in promoting pod maturity. However, care should be taken to control the dosage well and not fertilize blindly, otherwise it is easy to produce the opposite effect.
The above is a brief introduction to peanut fertilization timing and methods. The fertilization work for peanuts is very important throughout their entire growth period. If fertilization is improper, the impact on peanuts may be irreversible. That is all for today's introduction. This article is for reference only. Thank you all for reading and supporting.
